How We Chose the Best Solar Companies in Texas

If you're curious what we consider when choosing the best solar companies in Texas, you can visit our solar methodology page. We rate installers based on factors such as reputation, costs and financing, services offered, ease of installation process and customer experience.

Choosing the Best Solar Installer for Your Home

When evaluating which Texas solar installer is best for you, we advise considering the following:

Services Offered

The breadth, quality and relevance of services offered is an important factor in determining the best Texas solar installer for your needs. When you're considering solar companies, think about specific features or add-ons you may want, such as energy efficiency packages, solar financing, EV chargers or backup batteries.

Installation Process

Unsurprisingly, the ease and quality of the installation process itself is a main determinant of the best solar companies in Texas. Companies with more resources (like SunPower) may have easier installation processes than a local company. When speaking with solar representatives, we encourage you to ask what the installation process involves.

Steer clear of companies that hire subcontractors to carry out the installations, lack knowledge of local net metering and have bad customer reviews online. Most bad reviews come from snags during or after the installation.

Pricing and Financing

Though solar can provide clear long-term savings, the initial cost of solar panel installation can be significant and is often a deterrent for customers. Many solar panel companies now offer more flexible financing options than ever, however, determined to help you find a way to confidently navigate the finances of solar.

Industry Affiliations

To make sure that the renewable energy provider you select is trusted within the industry, we recommend checking for a few key certifications. These include whether the company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it belongs to the Solar Energy Industries Association (SEIA) or other industry groups.

Types of Panels

If it weren't clear by now, different companies offer different types of products. Panels, inverters, batteries and chargers all vary in their cost, quality, ethics and warranty. This is why we advise that you focus on companies that are certified to sell and install products from manufacturers with proven track records of quality and reliability.

Warranty

Going solar is a big investment, but a warranty can help you trust that your system functions as expected for decades. Most of the best solar companies in Texas provide warranties on their technology and workmanship for 25 years or more, but you'll definitely want to ask about this on the front end.

Cost of Solar in Texas

Based on market research and data from top solar panel brands, we found the average current cost of solar in Texas to be around $2.69 per watt. Using this average, we can calculate that after applying the federal solar tax credit, a 5-kW solar panel system would cost around $9,953 and a 10-kW system would cost around $19,906.

Any of the best solar companies in Texas should advise you on incentives and solar tax exemptions to reduce your overall project costs. In Texas, expertise in local incentives will be paramount to your choice, since the tax structure is so decentralized. Most incentives operate on a city or utility-specific basis, so we encourage you to check the DSIRE database to familiarize yourself with what's available in your area.

Here's a rundown of Texas solar incentives:

Texas Solar Incentive

Texas Solar Incentive Overview

Net Metering

Texas offers a robust net metering program that gives solar panel owners credits for the unused electricity generated by their panels. These credits can be used to pay for energy you pull from the grid at night.

Solar Sales Tax Exemption

Texas residents do not have to pay the state's 6.25% sales tax on solar panels or other eligible solar equipment.

Solar Property Tax Exemption

Installing solar panels boosts your property value in Texas, but the state doesn't require you to pay any additional taxes that would typically come with home add-ons.

You can learn more in our article covering solar incentives in Texas.

How to Find the Best Solar Installer in Texas

With Texas' massive energy needs continuing to rise, solar energy is poised to be a big part of the Lone Star state's future. We expect government policy to continue to direct more investment toward renewable energy sources like wind and solar throughout the state. These incentives will likely continue to be led by cities or specific utilities, so in Texas, we place extra emphasis on finding a solar company with proven expertise in local tax structures and policies.

We recommend getting quotes from a handful of installers. With competing offers, you can potentially find thousands of dollars worth of value while expanding your knowledge of the solar incentives available to you.

What We Like: Lumina Solar offers fully integrated solar technology to help its customers make a practical leap to new levels of energy efficiency, conservation and independence. Lumina’s solar panel systems are built with cutting-edge technology, and the company was the first in the state to offer Tesla Powerwall batteries. Though a young company, the team is made up of industry veterans sure to provide an aesthetically pleasing, reliable installation.

What We Don’t Like: Lumina Solar is only a 4-year-old company, albeit an impressive one. Given that warranties are only valid if your chosen company stays in business, we typically advise choosing companies with closer to 10 years of experience and that have a proven, sustainable business model.

What Customers Are Saying: “Lumina installed my solar system a couple of months ago, and I want everyone to know how fantastic this company is.

Installing Silfab, Longi, Q Cells and REC solar panels (which are some of the best available), Solar Energy World offers high-quality technology backed by a simple and tested process.

What We Don’t Like: Relative to some competitors on this list, Solar Energy World’s size can cause lapses in organizational presence and individualized attention. Those seeking a highly personalized, hands-on experience may be better off with a smaller company.

What Customers Are Saying: “Every step of the entire process was great — a low-pressure and knowledgeable consultation, a realistic and well-priced estimate (that turned out to match the design exactly), all steps in the process happened on or before schedule, the installation was quick and easy and neat (with cleanup), county inspection and all of the after-sale steps were taken care of quickly.” — Daniel via BBB

SunPower's reputation for excellent customer care and all-in-one solar solutions earns it a high spot on our list of the best Maryland solar installers.

What We Don’t Like: SunPower is a national company, working with local dealers in Maryland to install its systems. As a result, the quality of your workmanship will be fairly dependent on the SunPower dealer nearest you.

What Customers Are Saying: “Very knowledgeable, professional and easy to work with. I was pleasantly surprised that the entire staff has been very helpful and not "pushy" like other solar companies.” — Scott via BBB

Celestial Solar Innovations

Location: Northwest Maryland; Based in Frederick

What We Like: A local company with a passion for solar and exceptional service, Celestial Solar Innovations offers flexible solar financing options and knows the ins and outs of Maryland policies to ensure its customers receive the best possible value for their investment in solar power. Its strong Maryland roots make homeowners feel their experience is valued over profits, and stellar customer reviews back this sentiment.

What We Don’t Like: Celestial Solar Innovations only offers services in a small region of Northwest Maryland. This can be advantageous to customers in the area, as it means they receive more attention for their projects, but the majority of Maryland will be left outside Celestial Solar Innovations’ service area.

What Customers Are Saying: “Celestial Solar was a joy to work with. We had numerous estimates before meeting with Jim and CSI. They delivered on every promise. Not a hiccup. The system they installed works very well and is delivering in excess of 100% power. Each month, in addition to a zero-dollar power bill, there is an overage that we are now selling each month as SRECs (they set that up as well).” — Nate via Google Reviews

Add a comprehensive service range that includes energy solutions, audits and upgrades, and it’s no surprise Edge Energy consistently ranks as one of the best solar companies in Maryland.

What We Don’t Like: SunPower’s solar panels are some of the best in the business, especially when it comes to efficiency. However, this lone offering can be limiting to customers who may not need the most efficient solar panels or who are interested in purchasing a different brand of products.

What Customers Are Saying: “Edge Energy used the best quality solar panels and related equipment. They did a great job of installation. Their system provides an online account that keeps track of solar production and energy usage. I have produced more energy than I use and been paid back by the energy companies for the energy I produce.” — Bryan via Google Reviews

Edge Energy at a Glance:

  • Year Founded: 2006
  • Services Provided: Solar panels, backup battery installations, energy efficiency upgrades
  • Warranty: 25-year all-in-one warranty via SunPower

Trinity Solar

Location: State of Maryland

What We Like: One of the more established companies in the solar business, family-owned Trinity Solar is the largest privately held residential solar installation company in the nation. With over 80,000 installations under its belt, Trinity Solar is a reliable choice for home and business owners in Maryland.

What We Don’t Like: The Trinity’s size has led to some issues in communication. We’ve seen reviews lately from customers who have struggled to get in touch with customer service.

What Customers Are Saying: “From the very first day someone came out to look at my house ‘til the day it was finished, Trinity was great! Always on time and did what they said they were going to do each and every time. Best part was, they kept me informed all the time. If you're going solar, Trinity is the company you want doing it.” — George via BBB

Pairing roofing experts with solar specialists, American Sentry Solar offers residential and commercial installations and upgrades of the highest quality at a competitive price.

What We Don’t Like: Though we love the Enphase Encharge 10, we’d like to see American Sentry Solar offer other solar battery options to its customers.

What Customers Are Saying: “Other than the competitive price offered by American Sentry Solar, we were very pleased with their guarantee, warranty and monitoring plan included with the system. They answered our questions and gave us step-by-step information on what to expect for the whole process. Our panels are neatly arranged and look great on our roof. I love to think of all the money I am saving while sitting by the pool looking up at our panels.” — Jackie via Google Reviews

What We Like: Relative to its competitors, Energy Select offers the most comprehensive service we’ve seen when it comes to the overall efficiency and performance of your home or business’s energy system. We love seeing companies that stress minimizing energy use before moving on to installing solar panels. Energy efficiency upgrades can reduce the number of solar panels you’ll need, in most cases greatly reducing overall project costs.

What We Don’t Like: As with American Sentry Solar, we’d like to see Energy Select expand its battery offerings. Currently, it only offers the LG Chem.

What Customers Are Saying: “This service is amazing. All involved were professional and paid great attention to our questions. They are fast and leave the property clean and all trash removed. The difference in the home is amazing. All persons involved from start to finish are the best in their field. I would give them more than 5 stars.” — Frances via Google Reviews

What We Don’t Like: Maryland Solar Solutions’ focused approach can be limiting for customers seeking add-ons like backup battery installations or EV chargers.

What Customers Are Saying: “We were impressed with the quality and efficiency of the panels used by MSSI as compared with other companies. Furthermore, their commitment to customer service is unsurpassed. They were knowledgeable and very helpful through the entire process, from HOA approval to installation to coordinating with BGE to registering to sell the extra energy we produce.” — Wilma via Google Reviews

Maryland Solar Solutions at a Glance:

  • Year Founded: 2008
  • Services Provided: Solar panel installations, energy efficiency audits

How We Chose the Best Solar Companies in Maryland

Our company selection process includes researching the product portfolios, solar services, financing options, customer feedback and industry reputations of every major Maryland installer. Looking at metrics in these categories, we rated and ranked each company to narrow down our list of the nine best solar companies in Maryland. See our solar methodology for more information.

Choosing the Best Solar Installer for Your Home

There’s a great deal that goes into determining the best solar installer for your home, including your region, utility company, electric bills, roof space, energy consumption and more. The following factors might help you consider what to prioritize when choosing the best Maryland solar installer for your home or business.

Services Offered

Solar installation companies in Maryland will vary in service offerings and specializations. For instance, Maryland Solar Solutions chooses to focus strictly on solar panels, while companies like Edge Energy prioritize efficiency and home energy upgrades and use panels only to supplement your home’s energy system. Think about what makes your home or business unique — then find a company that prioritizes those needs. Other things to consider might be whether you need roofing work, EV chargers or backup power systems.

Installation Process

Before you sign a contract, make sure you're confident in your understanding of the installation process. Here are a few questions you’ll want the answers to:

  • How long does permitting take in my area?
  • What is my utility company's net metering policy?
  • Will any add-ons be installed along with the solar?
  • How long will the entire process take?

Permitting and interconnection can vary from city to city, so it's best to be sure you have realistic expectations.

Solar Pricing and Financing

Home solar is a great investment — especially in Maryland. Solar’s payback period can vary anywhere from 5 to 12 years (on average), so think about whether you might need special financing options to fit solar into your budget. Maryland is full of experienced solar installers familiar with the difficulties of high up-front costs, so be sure to ask about flexibility in financing options.

Industry Affiliations

It’s a good idea to hire a company that maintains industry credentials, such as membership in the Solar Energy Industries Association (SEIA), a B Corp certification or affiliation with other professional associations. Memberships and certifications are a great indicator of the company's professionalism, workmanship, reputation and reliability.

Types of Panels

Some types of solar panels are better than others, and each installer will offer a differing portfolio of products. Small homes in confined areas will likely need high-efficiency solar panels, while commercial projects with more space can prioritize the most affordable solar panels. It can only help to ask what brands of panels your company is certified to sell and install. Certifications from some of the best solar panel brands like Tesla, Panasonic, LG or REC might also be a good indicator of legitimacy.

Incentives, Rebates and Tax Credits

Maryland offers some of the best solar incentives in the country. Though effective, these incentives can be difficult to navigate, and finding a solar installer with experience securing the best value from these incentives may provide the best return on investment in the long run. It pays to think locally. Does the company you're looking at have plenty of experience in your community?

Warranty

Most warranty issues with solar don’t stem from the panels themselves, but instead from the workmanship of the installer. As a result, we recommend choosing a solar provider with a robust workmanship or all-in-one warranty to avoid any issues to your roof or home that may emerge months to years after installation. Most reputable solar companies will offer at least a 10-year warranty that covers workmanship.

Cost of Solar in Maryland

As of 2022, our market research and data from solar brands conclude the average cost of solar in Maryland is around $2.77 per watt. This means a 5-kW system would cost around $10,261 after the federal solar tax credit is applied. Keep in mind that a 5-kW system is about the minimum size you'll need for your home.

Luckily for those in Maryland, the state offers a number of helpful incentives (in addition to the federal tax credit) to help reward residents who switch to clean energy. Visit the DSIRE database for more information on incentives in your area.

Maryland Solar Incentive

Maryland Solar Incentive Overview

Solar Renewable Energy Certificates (SRECs)

Maryland rewards its residents with SRECs for contributing to the state’s renewable portfolio standard. SRECs are certificates earned for every MWh of clean energy generated that can be sold through the SREC market to help offset the cost of solar.

Residential Clean Energy Grant Program

A much simpler incentive to understand than SRECs, Maryland’s residential clean energy grant program sends you a direct $1,000 rebate for installing a solar energy system of at least 1 kW.

Sales & Property Tax Exemptions

Solar installations in the Free State are exempt from paying both the sales and property taxes associated with your solar purchase and added property value.

Maryland Net Metering

Maryland has a statewide net metering program that allows you to sell excess solar energy back to the grid in exchange for credits that go toward any future utility bills.

2022 Florida Solar Tax Credits, Incentives & Rebates

See how you can save money on solar panels in Florida.

Florida is well-known as the Sunshine State because of its year-round sunny weather that draws millions of tourists each year, but historically, Florida hasn't actually been a national leader when it comes to solar energy generation. That said, financial incentives like Florida solar tax credit and rebate opportunities have played a huge part in its rise to become one of the top states for solar energy.

To the glee of clean energy advocates across the state, various Florida solar incentives have succeeded in bringing solar power throughout the state. According to the Solar Energy Industries Association, in 2020, Florida ranked third in the nation for solar energy capacity, and it had the second-most installations during the second quarter of 2021.

This progress in the solar field comes from many different sources, not the least of which is Florida solar incentives. For any homes or businesses feeling left behind while the rest of the state goes solar, these types of solar tax credits are still widely available across Florida, which will be discussed in this article.

For most homeowners, the decision to go solar comes down to cost. To see how much you'd pay for a home solar system (and how much you can shave off that price with Florida solar tax credit and incentive opportunities), you can get a free quote from a top solar company near you by using this tool or filling out the form below.

Florida Solar Tax Credits and Solar Rebates

As much as transitioning to clean energy is the best thing for the environment and the fight against climate change, the reality has always been that such changes would be slow to happen (if they happened at all) unless they made sense financially. When solar energy systems are proven to save money for those who pay the high upfront costs to install them, those purchases are better considered a worthy investment.

As such, some of the most effective policies encouraging solar installations have been those making the decision a no-brainer from the budgetary perspective. Let's take a look at some of the top Florida solar incentives.

Florida Solar Incentive Program Overview
Florida Net Metering Programs Credits homeowners when their solar panels produce extra electricity and it is exported to the local power grid
Florida Tax Exemptions Property tax exemptions and sales tax exemptions for solar and other renewable energy equipment
Local Incentives Incentives, rebates and low-interest financing programs at the town, city, and county level that encourage local solar installations

Florida Net Metering Programs

Regardless of the state, one of the most critical types of energy policy for solar panels is known as net metering. Through net metering, homeowners can feed excess electricity produced by their solar panels into the power grid in exchange for utility credits. These credits can be used to pay for the energy a home uses when panels aren't producing (such as at night).

Net metering tends to be a state-by-state policy, as there is no federal policy regarding net metering. Florida is one of the states where there is, in fact, a statewide net metering program, applicable for homeowners regardless of which utility serves their area.

The specific net metering provision covers up to 2 megawatts (MW) of capacity for any customers who generate electricity with a renewable energy source. Florida Power & Light and Duke Energy have the largest net metering programs in the state.

The availability of such net metering serves as an incentive for Floridians to install solar panels on their property. Not only do they benefit by reducing their power bills from pulling energy from the grid less often, but they can even profit when the utility pays them for generating more power than they consume, bringing their solar payback period down.

Florida Solar Tax Exemptions

Another financial mechanism that the Florida state government offers to solar system owners is solar tax exemptions. To start, Florida doesn't want to make the upfront cost to purchase and install solar equipment to be any higher than the open market says it should be, so since 1997, all solar energy systems have been completely exempt from Florida's sales and use tax.

Once a solar photovoltaic system is purchased and installed, there is a statewide property tax abatement that further helps homeowners avoid paying taxes on it. Most home additions, such as a new shed or outdoor patio built in a home's backyard, would be appraised to determine the value it added to the property and thus increase the overall property tax. However, the added home value of solar panels is excluded from the property's taxable value.

Local Incentives

Florida is also a large, diverse state, so in addition to the state solar incentives, many local jurisdictions enact their own policies to encourage and support installation of solar energy systems. At the town, city or county level, Floridians will commonly find low-interesting solar financing options, specific solar incentives or rebates, and more.

You can determine whether your locality offers such incentives by investigating your local government websites or talking to utility company representatives. When you do, you may come across such successful programs as Jacksonville's $2,000 rebate for solar battery installations, Boynton Beach's Energy Edge Rebate Program, or the Solar Energy Rebate Grant Program offered by Dunedin.

Federal Solar Tax Credit

Floridians, of course, can also benefit from all the tax incentives, rebates and credits that are offered at the federal level. Over the past two decades, the federal solar investment tax credit (ITC) has attributed largely to the rapid growth in solar energy across business sectors, geographies and customer types.

For systems installed and operational before the end of 2022, the federal solar tax credit is equal to 26% of the value of the installation, dropping to 22% for systems installed in 2023. It is currently set to expire afterward, though the idea of extending the ITC beyond its current expiration date, as has been done in the past, has been a part of active clean energy policy debates.

FAQ: Florida Solar Incentives

Does Florida have a solar tax credit?

State-wide, there is no specific Florida solar tax credit. However, all utilities in the state of Florida do offer customers the ability to utilize net metering, Florida solar homeowners are eligible for the federal solar tax credit, and some local jurisdictions in Florida may offer their own tax credits.

Is solar tax exempt in Florida?

In Florida, the purchase and installation of a home solar system is exempt from all sales tax, and the value of renewable systems are excluded from 100% of residential property taxes.

How much is the solar tax credit for 2022?

For any solar panel system installed before the end of 2022, the federal solar investment tax credit is equal to 26% of the value of the system.

Is Florida a good state for solar?

Florida is a great state for solar from the perspective of having year-round sunny weather, higher-than-average solar irradiance and a policy landscape conducive to solar installations. Because of these factors, Florida ranked third among all states in terms of solar capacity installed in 2020 (rising to second when looking at the third quarter of 2021), per the SEIA.

How much do solar panels cost in Florida?

Based on market research and data from top solar companies, we've found the average cost of solar panels in Florida is $2.53 per watt. However, this is only an average, and prices can vary widely depending on where you live, the number of solar panels you need and more.

Titan Solar Power makes a great choice for homeowners far from the Phoenix area who may have limited access to its local solar companies.

How We Chose the Best Solar Companies in Arizona

Wondering how we chose the best solar companies in Arizona? We rate installers based on factors such as reputation, costs and financing, services offered, ease of installation process and customer experience. Visit our solar methodology page for more information.

Choosing the Best Solar Installer for Your Home

The best Arizona solar installer will be different for everyone. Each company varies in its location, services, financing and brands, and homeowners will place different weights on each depending on their needs. Overall, here's what we recommend keeping in mind:

Services Offered

Different solar installers are going to offer slightly different services. Design and installation of solar panels is one thing, but will the company also help install battery storage and an EV charging station for your electric car? Will it provide windows or weatherization to help boost your household's energy efficiency? You want to choose a full-service solar company whenever possible, unless you can pinpoint your specific needs.

Installation Process

Before you hire a solar company, it's helpful to ask about the installation process. Though it may seem simple, the process can vary a lot from company to company. Find out what the customization and design elements of solar panels will encompass. Also, keep in mind that some companies, like Titan Solar Power, hire third-party contractors to perform the work. Never assume anything when working with a solar installer.

Pricing and Financing

Installing solar panels is a significant investment on the front end, but ultimately pays for itself in tax credits and monthly electric bill savings. If that initial investment is a bit steep for you, you can always ask about solar payment plans and leasing opportunities. You never know what might be available to you until you ask.

Industry Affiliations

To ensure that the solar provider you hire is reputable and reliable, we recommend hiring a company that's held in high regard within the industry. Specifically, look for a provider with Solar Energy Industries Association (SEIA) affiliation and North American Board of Certified Energy Practitioners (NABCEP) certification.

Types of Panels

If you have your sights set on some of the best solar panel brands, it's important to check that the company you're speaking to is certified to install that brand. Most companies will post their certifications on their websites. If not, you can ask about brands when speaking to a solar energy consultant from one of Arizona's solar installers.

Incentives, Rebates and Tax Credits

As we mentioned, there are rebates and tax incentives to help offset the initial cost of your solar installation. Look for a solar company that can help you navigate these offers and obtain the savings you need.

Warranty

Most solar installers will include a warranty on their products and services, with 25-year warranties being the industry norm. These warranties can give some much-needed peace of mind that both the technology and workmanship behind your new photovoltaic system will hold up over the years.

Cost of Solar in Arizona

Based on market research and data from top solar panel brands, we found the average current cost of solar in Arizona to be around $2.61 per watt. Using this average, we can calculate that after applying the federal solar tax credit, a 5-kW solar panel system would cost around $9,657 and a 10-kW system would cost around $19,314.

The best solar companies in Arizona should have no trouble helping you find and apply for

local incentives and solar tax exemptions to offset a chunk of your solar costs.

Here's a rundown of Arizona's solar incentives:

Arizona Solar Incentive

Arizona Solar Incentive Overview

Arizona Residential Solar Energy Tax Credit

A state solar tax credit of 25% is available for residential solar systems in Arizona (maximum $1,000 personal income tax reduction).

Energy Equipment Property Tax Exemption

Arizona offers a property tax exemption on the added property value from solar.

Solar Equipment Sales Tax Exemption

Similar to the property tax exemption, Arizona allows an exemption on the state's 5.6% sales tax.

Federal Solar Tax Credit

The federal solar tax credit of 26% is available for solar energy systems purchased before December 31, 2022. The tax credit is set to phase out thereafter.

Regrettably, controversial policy in the state has all but phased out net metering incentives. However, it is still available in certain areas, so we encourage you to check with your local utility company to learn more.

How to Find the Best Solar Installer in Arizona

Arizona, the sunniest state in the nation, offers unparalleled value when it comes to harnessing the benefits of solar energy systems. The state has a long history of solar reliance, meaning there are a large number of experienced, reputable solar installers to choose from.

We understand that investing in a solar energy system can be intimidating, but the first step is actually pretty simple. We always recommend speaking with a few of Arizona's best solar installers to compare quotes and proposals. By comparing these quotes, you can get a better idea of what solar might cost you, and whether solar is worth it for your home or business.

How We Chose the Best Solar Companies in New York

We researched the product portfolios, solar services, financing options, customer feedback and industry reputations of every major New York solar installer. Using this methodology, we rated and ranked each company to narrow down and rank our picks for the top solar companies in New York.

Choosing the Best Solar Installer for Your Home

Everyone's needs are different when it comes to solar, so what may be the best solar company for your neighbor might not be right for you. Give these factors some thought and place more emphasis on what will meet your home's needs when choosing the best company for your installation:

Services Offered

To start, due to the unique range of needs of home and business owners in New York, a variety of solar installers focus on different services. For instance, Brooklyn SolarWorks focuses more exclusively on downtown roofs, which are typically flat and have needs different than a larger home in Long Island. Think about what makes your home or business unique — and find a company that prioritizes those needs. Other things to consider might be whether you need electrical upgrades, EV chargers or backup power.

Installation Process

Before you sign any paperwork, make sure you're confident in knowing how the installation process will look. How long before the installation day will happen? How many days will it take? What is my utility company's net metering policy? Permitting and interconnection can vary from city to city, so it's best to be sure you're familiar with the process.

Solar Pricing and Financing

Solar energy systems are a great investment — one that takes planning and time to mature. Think about whether you might need special financing options if your budget is tight. Any of the best solar companies in New York should be able to assist you in applying for the federal solar tax credit, but specific financing options and flexibility will vary from provider to provider.

Industry Affiliations

We generally recommend hiring a company that maintains industry credentials, such as membership in the Solar Energy Industries Association (SEIA), a B Corp certification or affiliation with other professional associations. Memberships and certifications are a great indicator of the company's professionalism, workmanship, reputation and reliability.

Types of Panels

Some types of solar panels are better than others, and each company will offer a slightly different product portfolio. Small homes in more dense cities will likely need high-efficiency solar panels, while homes with more space might opt for a sleek design. It can't hurt to ask what brands of panels your company has available, and why they might recommend each. Certifications from some of the best solar panel brands like Panasonic, LG or SunPower might also be a good indicator of legitimacy.

Incentives, Rebates and Tax Credits

New York State has a variety of solar incentives that can vary by city, county and utility. Though effective, these incentives can be complex, and finding a solar installer that knows the ins and outs of local policy may provide the best overall value in the long run. It's best to think locally here. Does the company you're looking at have plenty of experience in your community? This will be important.

Warranty

Finally, we recommend finding an installer that offers a good warranty. Solar panels are incredibly tough, but things happen. The best warranties will last 25 years and cover the equipment, workmanship and performance of your installation.

Cost of Solar in New York

As of 2022, our market research and data from top brands show the average cost of solar panels in New York is around $2.95 per watt. This means a 5-kW system would cost around $10,927 after the federal solar tax credit is applied. Keep in mind that a 5-kW system is about the minimum size for most homes.

New York State also offers a variety of solar incentives to help offset the cost of your system. These incentives have spurred the growth of solar in New York to new highs in 2021, pushing to over $7 billion of total investment. Under the right circumstances, New York's solar incentives are capable of offsetting nearly half of the aggregate system installation costs.

New York Solar Incentive

Incentive Description

NY-Sun Megawatt Block Incentive

This statewide incentive provides direct financial incentives for solar installations on a per-watt basis, meaning the larger your installation, the more financial support you'll receive.

Solar Energy System Equipment Credit

New York residents are entitled to claim a tax credit equal to 25% of your qualified solar energy system equipment expenditure (limited to $5,000).

Sales Tax Exemption

New York residents don't have to pay the state's 4% sales tax on qualified solar equipment.

Net Metering

Standard net metering is available to most New York residents through 2022. Throughout 2022, New York will begin enrolling its solar customers in a net metering alternative aimed at easing utility costs.

How to Find the Best Solar Installer in New York

Sorting through the large number of New York solar installers can seem challenging, but this actually presents a great opportunity for New York home and business owners. Unlike a number of other states, solar customers are far more likely to find a company that tailors to their local needs.

The large number of solar companies in New York also gives solar customers the opportunity to shop competing offers against each other, sometimes securing thousands of dollars during the process. Remember, these companies are competing for you.

Solar panels offer an excellent return on investment, and the savings you can expect over their 25- to 30-year service lives are much higher than their upfront costs. However, there are some performance issues that can affect solar panels, and they will undermine your savings if left unattended. Fortunately, most of these problems are relatively easy to solve, and major issues are covered by a warranty if you purchase high-quality solar panels.

In this article, we will discuss some common issues that may affect solar power systems, as well as how to solve them. By making sure that your solar panels stay productive, you get consistent savings each month and can shorten your solar panel payback period.

Common Issues That May Lower Solar Panel Output

When the electricity output of solar panels is lower than normal, there are many possible causes. However, the following are some of the most common:

Solar Panel Output Issue Issue Description
Dust and dirt Dust and dirt can accumulate on the surface of solar panels, partially blocking sunlight and decreasing their energy output.
Pollen Pollen can have the same effect as dirt and dust during the flowering season of plants.
Cloudy weather Although solar panels work on cloudy days, they do so at a much lower production rate.
Shade from trees Your solar panels may be covered by shadows from trees that were shorter when you installed the system.
Shade from new constructions Shadows from new constructions can also block the sunlight received by your panels. However, most states offer legal protection with solar easements. When you have an easement, neighbors can't build structures that block your solar system.
Disconnected components Solar systems use plenty of wiring, and components can get disconnected by accident.
Malfunctioning components If there's an issue with any part of your system — solar panels, wiring, circuit breakers, inverters, batteries, etc. — it can lead to a reduced panel output.
Seasonal variation Solar panels generate more electricity during summer.
Gradual efficiency loss Even the most efficient solar panels become less productive over time, but this happens at a very slow rate. The annual productivity loss is normally less than 0.5%.
Monitoring errors If you're experiencing what seems like a low output, there's a chance the panels are functioning normally but you have an issue with your monitoring system.

It's important to understand that solar panels will rarely generate their nameplate wattage — they are tested under ideal laboratory conditions, which are not achieved in rooftop installations. Solar manufacturers use the same testing conditions to allow a direct comparison of their products, but the actual electricity output depends on site conditions. You can have two homes with 360-watt solar panels of the same brand, and their electricity output can vary widely due to factors like local sunshine, roof orientation and ambient temperature.

Also, keep in mind that inverters are often sized smaller than the solar arrays connected to them. This is an economic decision: solar panels will rarely reach their peak output outside of laboratory settings, and an equally-sized inverter will rarely operate at rated capacity. Instead, the inverter "clips" the occasional solar power peaks that exceed its wattage.

The capacity relationship between a solar array and its inverter is described by the DC-to-AC ratio, also known as the inverter load ratio or ILR. For example, a 10-kW solar array with an 8-kW inverter has a DC-to-AC ratio of 1.25. This is designed to help homeowners save money on solar panel installations, but it can also occasionally lead to a lower-than-expected solar panel output.

How to Detect Issues with Your Solar Panels

If you suspect that your solar panels are suffering from low productivity, the first step is identifying the exact issue. You could be simply dealing with seasonal variations, or your solar panels could be in need of cleaning. However, your solar PV system could also be suffering a major malfunction, which requires professional attention and possibly a warranty claim.

Solar inverters from leading brands like Fronius and Sungrow come with built-in monitoring systems and mobile apps. You can check the daily output of your solar panels from a smartphone, and performance issues are reflected as a drop in the daily kilowatt-hour output. When this happens, you can start by ruling out normal variations in productivity and problems that are easy to fix, including:

  • Cloudy weather
  • Lower productivity during winter
  • Dust, dirt, pollen, leaves and other particles on the surface of your solar panels
  • Disconnected wires
  • Tripped circuit breakers

Solar panels can be expected to lose productivity over time, but this happens slowly — a sudden drop in electricity output normally means trouble. Keep in mind that the best solar panels lose less than 0.5% of their capacity each year. So if your system generated 10,000 kWh during its first year of operation, you can still expect around 9,950 kWh the second year.

You can also detect solar panel issues by keeping track of your electricity bills, but note that higher bills can have several causes. For example, if you live in a place with hot summers, you can expect air conditioning to increase your bills during that time of the year.

The best option is having a dedicated monitoring system for your solar panels, to obtain measurements that are not affected by other electrical devices. Older inverters may lack metering functions, but there are monitoring systems that offer compatibility with multiple inverter brands. Modern inverters can detect many types of faults on their own, and they will diagnose exactly what is happening. This makes troubleshooting much easier.

How to Address Issues and Maximize Solar Panel Efficiency

Many solar power issues can be fixed with cleaning and checking if there are loose connections or tripped breakers. However, some problems are a bit more challenging:

  • If your solar panels have been shaded by trees that were previously shorter, the trees must be trimmed. Moving solar panels is not recommended — it's more difficult than trimming trees, system components may be damaged and warranties could be voided.
  • Shading from new constructions can be prevented by getting a solar easement in advance. Just keep in mind that your neighbors must agree to sign it, or otherwise they have no legal impediment to build structures that cast shadows. Before installing your solar panels, take your time to research the constructions that are being planned in surrounding properties.

As mentioned above, there may be cases in which your monitoring system displays zero production but your solar panels are working normally. Or, there could really be an issue that prevents electricity production. In both cases, you should contact your solar PV system provider for an inspection. Waiting for the next power bill is not recommended, as you may get an unpleasant surprise.

Electrical faults and other major malfunctions are rare if your solar power system uses high-quality components installed by professionals. However, these issues can happen even with the best solar products.

Here are some key things to know about solar panel output issues:

  • You may be left without solar power for some days if there is a malfunction, but any damaged components will be replaced for free if you have a solid warranty.
  • Solar panels normally come with a 10- to 12-year warranty against manufacturing defects, and a 25- to 30-year power production warranty.
  • Inverters typically have a 5-year warranty, but there are extended warranty options from several manufacturers.
  • If your system includes a solar battery like the Tesla Powerwall, the typical warranty period is 10 years.

Generally, the company that installed your solar panels will help with warranty claims and component replacements if necessary. However, this only applies if you're dealing with professionals, which is just one reason it's important that you make sure you purchase your solar PV system from a qualified provider.

Even if your solar panels are working normally, there are many things you can do to use their electricity more efficiently and increase your savings. Adjust your energy consumption habits and program your appliances to operate around noon whenever possible, as this is when the sun is directly overhead. Avoid using appliances in the evening, when many electricity providers are charging their highest tariffs. Also, make sure your solar panels are cleaned regularly, or their kilowatt-hour output could drop significantly.

Solar panels allow you to harness the sun's clean, renewable energy, potentially cutting your electric bills as well as your environmental footprint. But do solar panels work on cloudy days, or during seasons of less-than-optimal sun exposure? For homeowners who live outside of the Sun Belt, this is a critical question to consider before moving ahead with solar panel installation.

In this article, we'll go over how solar panels work on cloudy days, whether solar panels work at night, and how to ensure you always have accessible power — even when your panels aren't producing solar energy.

How Solar Panels Work on Cloudy Days

Photovoltaic (PV) solar panels can use both direct and indirect sunlight to generate electrical power. This means they can still be productive even when there is cloud coverage. With that said, solar panels are most efficient and productive when they are soaking up direct sunlight on sunny days.

While solar panels still work even when the light is reflected or partially obstructed by clouds, their energy production capacity will be diminished. On average, solar panels will generate 10 to 25% of their normal power output on days with heavy cloud coverage.

With clouds usually comes rain, and here's a fact that might surprise you: Rain actually helps solar panels work more effectively. That's because rain washes away any dirt or dust that has gathered on your panels so that they can more efficiently absorb sunlight.

Do Solar Panels Work at Night?

While solar panels can still function on cloudy days, they cannot work at night. The reason for this is simple: Solar panels work because of a scientific principle called the photovoltaic effect, wherein solar cells are activated by sunlight, generating electrical current. Without light, the photovoltaic effect cannot be triggered, and no electric power can be generated.

One way to tell if your panels are still producing energy is to look at public lights. As a general rule of thumb, if street lamps or other lights are turned off — whether on cloudy days or in the evening — your solar panels will be producing energy. If they're illuminated, it's likely too dark out for your solar panel system to work.

Storing Solar Energy to Use on Cloudy Days and at Night

During hours of peak sunlight, your solar panels may actually generate more power than you need. This surplus power can be used to provide extra electricity on cloudy days or at night.

But how do you store this energy for future use? There are a couple of options to consider:

You can store surplus energy in a solar battery.

When you add a solar battery to your residential solar installation, any excess electricity can be collected and used during hours of suboptimal sun exposure, including nighttime hours and during exceptionally cloudy weather.

Batteries may allow you to run your solar PV system all day long, though there are some drawbacks of battery storage to be aware of:

  • It's one more thing you need to install.
  • It adds to the total cost of your solar system.
  • Batteries will take up a bit of space.
  • You will likely need multiple batteries if you want electricity for more than a handful of hours. For example, Tesla solar installations require two Powerwall batteries if your system is over 13 kilowatts.

You can use a net metering program.

Net metering programs enable you to transmit any excess power your system produces into your municipal electric grid, receiving credits from your utility company. Those credits can be cashed in to offset any electrical costs you incur on overcast days or at night when you cannot power your home with solar energy alone.

Net metering can ultimately be a cost-effective option and can significantly lower your electricity bills, but there are a few drawbacks to consider, including:

  • You may not always break even.
  • In some cases, you may still owe some money to your utility provider.
  • Net metering programs are not offered in all areas and by all utility companies.

Is Residential Solar Right for You?

Now that you know solar panels can work even when the sun isn't directly shining and that there are ways to store your energy for times your panels aren't producing electricity, you may be more interested in installing your own system.

FAQ: Do Solar Panels Work on Cloudy Days?

How efficient are solar panels on cloudy days?

It depends on the panels, but as a rule of thumb, you can expect your solar panels to work at 10 to 25% efficiency on cloudy days.

How do solar panels work when there is no sun?

If there is literally no sunlight (e.g., at night), then solar panels do not work. This is because the photovoltaic effect, which is the process through which panels convert sunlight into energy, requires there to be some light available to convert.

However, you can potentially use surplus solar power that you've stored in a battery. Also note that solar panels can work with indirect light, meaning they can function even when the sun is obscured by cloud coverage.

Do solar panels work on snowy days?

If there is cloud coverage and diminished sunlight, then solar panels will not work at their maximum efficiency level on snowy days. With that said, the snow itself is usually not a problem, particularly because a dusting of snow is easily whisked away by the wind.

Snow will only impede your solar panels if the snowfall is so extreme that the panels become completely buried, or if the weight of the snow compromises the integrity of your solar panel structures.

Will my solar panels generate electricity during cloudy, rainy or snowy days?

Cloudy days may limit your solar panel's efficiency, but you'll still be able to generate some electricity. Rainy days can actually help clean your panels, making them even more effective. And snowy days are only a problem if the snow is so extreme that the panels are totally submerged, without any part of them exposed to the sun.

How We Chose the Best Solar Companies in Texas

If you're curious what we consider when choosing the best solar companies in Texas, you can visit our solar methodology page. We rate installers based on factors such as reputation, costs and financing, services offered, ease of installation process and customer experience.

Choosing the Best Solar Installer for Your Home

When evaluating which Texas solar installer is best for you, we advise considering the following:

Services Offered

The breadth, quality and relevance of services offered is an important factor in determining the best Texas solar installer for your needs. When you're considering solar companies, think about specific features or add-ons you may want, such as energy efficiency packages, solar financing, EV chargers or backup batteries.

Installation Process

Unsurprisingly, the ease and quality of the installation process itself is a main determinant of the best solar companies in Texas. Companies with more resources (like SunPower) may have easier installation processes than a local company. When speaking with solar representatives, we encourage you to ask what the installation process involves.

Steer clear of companies that hire subcontractors to carry out the installations, lack knowledge of local net metering and have bad customer reviews online. Most bad reviews come from snags during or after the installation.

Pricing and Financing

Though solar can provide clear long-term savings, the initial cost of solar panel installation can be significant and is often a deterrent for customers. Many solar panel companies now offer more flexible financing options than ever, however, determined to help you find a way to confidently navigate the finances of solar.

Industry Affiliations

To make sure that the renewable energy provider you select is trusted within the industry, we recommend checking for a few key certifications. These include whether the company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it belongs to the Solar Energy Industries Association (SEIA) or other industry groups.

Types of Panels

If it weren't clear by now, different companies offer different types of products. Panels, inverters, batteries and chargers all vary in their cost, quality, ethics and warranty. This is why we advise that you focus on companies that are certified to sell and install products from manufacturers with proven track records of quality and reliability.

Warranty

Going solar is a big investment, but a warranty can help you trust that your system functions as expected for decades. Most of the best solar companies in Texas provide warranties on their technology and workmanship for 25 years or more, but you'll definitely want to ask about this on the front end.

Cost of Solar in Texas

Based on market research and data from top solar panel brands, we found the average current cost of solar in Texas to be around $2.69 per watt. Using this average, we can calculate that after applying the federal solar tax credit, a 5-kW solar panel system would cost around $9,953 and a 10-kW system would cost around $19,906.

Any of the best solar companies in Texas should advise you on incentives and solar tax exemptions to reduce your overall project costs. In Texas, expertise in local incentives will be paramount to your choice, since the tax structure is so decentralized. Most incentives operate on a city or utility-specific basis, so we encourage you to check the DSIRE database to familiarize yourself with what's available in your area.

Here's a rundown of Texas solar incentives:

Texas Solar Incentive

Texas Solar Incentive Overview

Net Metering

Texas offers a robust net metering program that gives solar panel owners credits for the unused electricity generated by their panels. These credits can be used to pay for energy you pull from the grid at night.

Solar Sales Tax Exemption

Texas residents do not have to pay the state's 6.25% sales tax on solar panels or other eligible solar equipment.

Solar Property Tax Exemption

Installing solar panels boosts your property value in Texas, but the state doesn't require you to pay any additional taxes that would typically come with home add-ons.

You can learn more in our article covering solar incentives in Texas.

How to Find the Best Solar Installer in Texas

With Texas' massive energy needs continuing to rise, solar energy is poised to be a big part of the Lone Star state's future. We expect government policy to continue to direct more investment toward renewable energy sources like wind and solar throughout the state. These incentives will likely continue to be led by cities or specific utilities, so in Texas, we place extra emphasis on finding a solar company with proven expertise in local tax structures and policies.

We recommend getting quotes from a handful of installers. With competing offers, you can potentially find thousands of dollars worth of value while expanding your knowledge of the solar incentives available to you.

What We Like: Lumina Solar offers fully integrated solar technology to help its customers make a practical leap to new levels of energy efficiency, conservation and independence.

Though a young company, the team is made up of industry veterans sure to provide an aesthetically pleasing, reliable installation.

What We Don’t Like: Lumina Solar is only a 4-year-old company, albeit an impressive one. Given that warranties are only valid if your chosen company stays in business, we typically advise choosing companies with closer to 10 years of experience and that have a proven, sustainable business model.

Installing Silfab, Longi, Q Cells and REC solar panels (which are some of the best available), Solar Energy World offers high-quality technology backed by a simple and tested process.

What We Don’t Like: Relative to some competitors on this list, Solar Energy World’s size can cause lapses in organizational presence and individualized attention. Those seeking a highly personalized, hands-on experience may be better off with a smaller company.

What Customers Are Saying: “Every step of the entire process was great — a low-pressure and knowledgeable consultation, a realistic and well-priced estimate (that turned out to match the design exactly), all steps in the process happened on or before schedule, the installation was quick and easy and neat (with cleanup), county inspection and all of the after-sale steps were taken care of quickly.” — Daniel via BBB

Celestial Solar Innovations

Location: Northwest Maryland; Based in Frederick

Its strong Maryland roots make homeowners feel their experience is valued over profits, and stellar customer reviews back this sentiment.

What We Don’t Like: Celestial Solar Innovations only offers services in a small region of Northwest Maryland. This can be advantageous to customers in the area, as it means they receive more attention for their projects, but the majority of Maryland will be left outside Celestial Solar Innovations’ service area.

What Customers Are Saying: “Celestial Solar was a joy to work with. We had numerous estimates before meeting with Jim and CSI. They delivered on every promise. Not a hiccup. The system they installed works very well and is delivering in excess of 100% power.

What We Don’t Like: SunPower’s solar panels are some of the best in the business, especially when it comes to efficiency. However, this lone offering can be limiting to customers who may not need the most efficient solar panels or who are interested in purchasing a different brand of products.

What Customers Are Saying: “Edge Energy used the best quality solar panels and related equipment. They did a great job of installation. Their system provides an online account that keeps track of solar production and energy usage. I have produced more energy than I use and been paid back by the energy companies for the energy I produce.” — Bryan via Google Reviews

With over 80,000 installations under its belt, Trinity Solar is a reliable choice for home and business owners in Maryland.

What We Don’t Like: The Trinity’s size has led to some issues in communication. We’ve seen reviews lately from customers who have struggled to get in touch with customer service.

What Customers Are Saying: “From the very first day someone came out to look at my house ‘til the day it was finished, Trinity was great! Always on time and did what they said they were going to do each and every time. Best part was, they kept me informed all the time.

What Customers Are Saying: “Other than the competitive price offered by American Sentry Solar, we were very pleased with their guarantee, warranty and monitoring plan included with the system. They answered our questions and gave us step-by-step information on what to expect for the whole process. Our panels are neatly arranged and look great on our roof.

How We Chose the Best Solar Companies in Maryland

Our company selection process includes researching the product portfolios, solar services, financing options, customer feedback and industry reputations of every major Maryland installer. Looking at metrics in these categories, we rated and ranked each company to narrow down our list of the nine best solar companies in Maryland. See our solar methodology for more information.

Choosing the Best Solar Installer for Your Home

There’s a great deal that goes into determining the best solar installer for your home, including your region, utility company, electric bills, roof space, energy consumption and more. The following factors might help you consider what to prioritize when choosing the best Maryland solar installer for your home or business.

Services Offered

Solar installation companies in Maryland will vary in service offerings and specializations. For instance, Maryland Solar Solutions chooses to focus strictly on solar panels, while companies like Edge Energy prioritize efficiency and home energy upgrades and use panels only to supplement your home’s energy system. Think about what makes your home or business unique — then find a company that prioritizes those needs. Other things to consider might be whether you need roofing work, EV chargers or backup power systems.

Installation Process

Before you sign a contract, make sure you're confident in your understanding of the installation process. Here are a few questions you’ll want the answers to:

  • How long does permitting take in my area?
  • What is my utility company's net metering policy?
  • Will any add-ons be installed along with the solar?
  • How long will the entire process take?

Permitting and interconnection can vary from city to city, so it's best to be sure you have realistic expectations.

Solar Pricing and Financing

Home solar is a great investment — especially in Maryland. Solar’s payback period can vary anywhere from 5 to 12 years (on average), so think about whether you might need special financing options to fit solar into your budget. Maryland is full of experienced solar installers familiar with the difficulties of high up-front costs, so be sure to ask about flexibility in financing options.

Industry Affiliations

It’s a good idea to hire a company that maintains industry credentials, such as membership in the Solar Energy Industries Association (SEIA), a B Corp certification or affiliation with other professional associations. Memberships and certifications are a great indicator of the company's professionalism, workmanship, reputation and reliability.

Types of Panels

Some types of solar panels are better than others, and each installer will offer a differing portfolio of products. Small homes in confined areas will likely need high-efficiency solar panels, while commercial projects with more space can prioritize the most affordable solar panels. It can only help to ask what brands of panels your company is certified to sell and install. Certifications from some of the best solar panel brands like Tesla, Panasonic, LG or REC might also be a good indicator of legitimacy.

Incentives, Rebates and Tax Credits

Maryland offers some of the best solar incentives in the country. Though effective, these incentives can be difficult to navigate, and finding a solar installer with experience securing the best value from these incentives may provide the best return on investment in the long run. It pays to think locally. Does the company you're looking at have plenty of experience in your community?

Warranty

Most warranty issues with solar don’t stem from the panels themselves, but instead from the workmanship of the installer. As a result, we recommend choosing a solar provider with a robust workmanship or all-in-one warranty to avoid any issues to your roof or home that may emerge months to years after installation. Most reputable solar companies will offer at least a 10-year warranty that covers workmanship.

Cost of Solar in Maryland

As of 2022, our market research and data from solar brands conclude the average cost of solar in Maryland is around $2.77 per watt. This means a 5-kW system would cost around $10,261 after the federal solar tax credit is applied. Keep in mind that a 5-kW system is about the minimum size you'll need for your home.

Luckily for those in Maryland, the state offers a number of helpful incentives (in addition to the federal tax credit) to help reward residents who switch to clean energy. Visit the DSIRE database for more information on incentives in your area.

Maryland Solar Incentive

Maryland Solar Incentive Overview

Solar Renewable Energy Certificates (SRECs)

Maryland rewards its residents with SRECs for contributing to the state’s renewable portfolio standard. SRECs are certificates earned for every MWh of clean energy generated that can be sold through the SREC market to help offset the cost of solar.

Residential Clean Energy Grant Program

A much simpler incentive to understand than SRECs, Maryland’s residential clean energy grant program sends you a direct $1,000 rebate for installing a solar energy system of at least 1 kW.

Sales & Property Tax Exemptions

Solar installations in the Free State are exempt from paying both the sales and property taxes associated with your solar purchase and added property value.

Maryland Net Metering

Maryland has a statewide net metering program that allows you to sell excess solar energy back to the grid in exchange for credits that go toward any future utility bills.

How to Find the Best Solar Installer in Maryland

Maryland's renewable energy incentive structure makes it unique in the solar market, focusing on SRECs, grants, tax exemptions and more. As stated before, these can be very effective but intimidating and difficult to navigate. This is why we stress the importance of finding a solar company with experience applying for these incentives and with a proven history of maximizing its customers’ solar investments.

If you’re ready to take the first step, we recommend comparing quotes from some of Maryland’s top solar installers. From there, you can see which company offers the best rates and ask more specific questions about incentives, experience and more.

FAQ: Best Solar Companies in Maryland

Who is the most reputable solar company in Maryland?

The most reputable solar company in Maryland may be SunPower, due to its size and national acclaim. However, there are plenty of reputable local companies as well, including Lumina Solar and Solar Energy World.

Is there a solar tax credit in Maryland?

Though there is no statewide tax credit, Maryland offers direct payments of $1,000 to homeowners that install solar via its residential clean energy grant program. The federal solar tax credit is also available to residents of Maryland, along with SRECs, net metering, and sales and property tax exemptions.

How do I find a reputable solar company?

If you’re looking for a reputable solar company in Maryland, you’re in the right place. We recommend starting with this list, narrowing in on your region, and gathering free quotes from the providers available to service your energy needs. From there, you can compare quotes to find the best value and speak with representatives to pinpoint which offer seems best for you.
