A new California mapping project reveals another example of how the climate crisis disproportionately impacts vulnerable and disadvantaged communities.

The Toxic Tides project, unveiled during a virtual workshop Tuesday, maps more than 400 hazardous sites like power plants, refineries and toxic waste dumps that could flood if sea levels rise by more than three feet, which they are projected to do by the end of 2100 if little is done to resolve the climate crisis. This is a major environmental justice issue, because these sites are disproportionately located in low income communities of color.

Comparing the 10 Best Solar Companies in Maryland

Lumina Solar

Lumina Solar logo

Lumina Solar

Location: Maryland, Pennsylvania and Virginia; Based in Baltimore

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. I urge anyone looking to make the switch to call Lumina Solar. From the very beginning of researching solar companies, I was most impressed with customer reviews and they were absolutely right.” — Marsha via Better Business Bureau (BBB)

Solar Energy World

Location: State of Maryland; Based in Elkridge

What We Like: Solar Energy World’s excellent industry reputation across the East Coast continues to shine each year, making it one of the fastest-growing independently owned and operated solar companies in the region. In fact, Solar Energy World has ranked as the No. 1 residential solar installer by volume in Maryland five years running. 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

Solar Energy World at a Glance:

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

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

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 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.

Energy efficiency upgrades can reduce the number of solar panels you’ll need, in most cases greatly reducing overall project costs.

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.

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.

North Carolina consistently ranks among the top states for solar energy, but what kinds of incentives are residents able to take advantage of to lower the cost of going solar? In this article, we’ll provide an overview of all North Carolina solar tax credit, rebate and other incentive opportunities available to homeowners, which have contributed to the local growth of clean energy.

The SEIA gathers detailed information about the solar industry in each state, and the outlook for North Carolina is very promising. According to the latest SEIA data, the state has over 7,200 megawatts of solar capacity, which is enough to power more than 846,000 homes. The accumulated investment in North Carolina’s solar industry now exceeds $9.8 billion, with more than 6,100 jobs created so far.

North Carolina has enacted favorable legislation for solar power. There is a net metering policy, which ensures you get full credit when exporting surplus solar energy to the grid. There is also a law that enables low-interest green energy loans from county and city governments. Let’s dig in.

North Carolina Solar Incentives

Although there are sunnier regions in the U.S., the Global Solar Atlas shows North Carolina gets decent sunshine. The state also offers several incentive programs that improve your return on investment when going solar.

North Carolina Solar Incentive

Program Overview

Property Tax Abatement for Solar Electric Systems

North Carolina does not tax you for the increase in property value after installing solar panels.

North Carolina Net Metering Policy

Surplus electricity from your home solar system is credited at retail price on your next power bill.

Duke Energy Solar Rebate

Duke Energy customers can qualify for a cash incentive when installing a solar panel system.

Local Option - Financing Program for Renewable Energy and Energy Efficiency

North Carolina has a law that enables revolving loan programs from cities and counties, with a maximum interest rate of 8% and a maximum term of 20 years.

Local Incentives

Additional incentives may be available from your county, city or utility company.

We'll go into detail about each North Carolina solar incentive below, but if you haven't already, we recommend getting a free quote from a certified installer in your area to see exactly how much these tax credits and rebates could save you. To get started, you can use this tool or fill out the following form:

North Carolina Solar Tax Incentives

North Carolina has offered a property tax exemption for solar panels and solar thermal electric systems since 2008. These systems increase the value of your property, like any other home upgrade, but NC does not tax you for that increase. For example, if solar panels increase the value of a home from $270,000 to $300,000, the owner will still be taxed for a $270,000 home.

This benefit is also available for solar power systems owned by commercial, industrial and agricultural energy users. However, in these cases, the property tax exemption applies for 80% of the system’s value, instead of the 100% exemption available for homeowners.

Net Metering in North Carolina

North Carolina offers net metering for solar power systems up to 1,000 kW of capacity, which covers all residential systems and many industrial and commercial solar systems. However, leased solar systems have a much lower limit for net metering: 20 kW or 100% of estimated demand, whichever is less.

Surplus electricity from your solar panels is credited on your next bill, which means you save the full value of the kilowatt-hours that get exported to the grid. However, your accumulated balance expires at the start of the summer billing period. Having an optimally sized solar power system is recommended, since an oversized system generates electricity that you can never subtract from your bills.

Duke Energy Solar Rebate

If you’re a Duke Energy customer who plans to install solar panels, you may qualify for the utility company’s North Carolina Solar Rebate Program. The available funding for 2021 ran out very quickly, but you can join a waiting list for when the program reopens in 2022. The incentive per kilowatt changes depending on the type of customer, but the program website lists the following rates as of November 2021:

  • Residential customer: $400 per kW, maximum system size of 10 kW ($4,000)
  • Non-residential customer: $300 per kW, maximum system size of 100 kW ($30,000)
  • Nonprofit organization: $750 per kW, maximum system size of 100 kW ($75,000)

Keep in mind that incentive programs managed by energy companies tend to change frequently, and their funding per year is limited. If you’re interested in the Duke Energy rebate, check the company’s website regularly so you don’t miss any updates.

NC Financing Program for Renewable Energy and Energy Efficiency

In North Carolina, city and county governments are legally authorized to offer low-interest loans for solar PV systems in homes and businesses. The loan program also covers other renewable energy technologies like geothermal heat pumps, wind turbines and biomass power.

The maximum interest rate of these revolving loans is 8%, and the maximum term is 20 years. This gives you the option of installing a solar panel system with loaned capital, then using your electricity savings to pay it back over time. This means your out-of-pocket cost is reduced to zero, and your solar power system can cover its own cost with the savings achieved.

Local Incentives

We have listed the main solar incentives available in North Carolina, but keep in mind that additional benefits may be available depending on where you live.

For example, the City of Asheville offers building permit rebates for homeowners and businesses who use solar panels and other green energy technologies. This North Carolina solar rebate changes depending on the technology used; in the case of solar panels, there is a $50 rebate on your building permit application.

Federal Solar Tax Credit

The federal solar tax credit is not a North Carolina incentive, strictly speaking, since you can claim it anywhere in the U.S. However, we mention this benefit here because you can combine it with local incentives.

  • If you install a solar power system before the end of 2022, you can claim 26% of its value as a federal tax credit.
  • The benefit will remain available in 2023, but it will be reduced to 22%.
  • After the start of 2024, there will only be a 10% federal solar tax credit for businesses and 0% for homes.

FAQ: North Carolina Solar Incentives

Does North Carolina have a solar tax credit?

No, there is no specific North Carolina solar tax credit. However, you can still claim the 26% federal tax credit.

Is it worth going solar in North Carolina?

It depends on your unique situation, but in general, it’s worth going solar in North Carolina. The state offers a combination of incentives that reduce your ownership costs and decent sunshine that makes solar panels productive. Solar panels last for more than 25 years if they’re of high quality, and you can achieve a payback period of less than 10 years in North Carolina.

Does solar increase property taxes in North Carolina?

No, there is a 100% property tax exemption for residential solar systems. Your home becomes more valuable, but your property taxes are not raised. Solar power systems owned by businesses get an 80% property tax exemption.

What is the 26% tax credit for solar?

In a few words, for every dollar invested in a solar power system, you can claim 26 cents on your next tax declaration. For example, if you purchase a 6-kW home solar system for $18,000, you can claim a tax credit of $4,680 (26% of $18,000).
