Comparing the 6 Best Solar Companies in Maryland

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)

Lumina Solar at a Glance:

  • Year Founded: 2018
  • Services Provided: Solar panels, backup battery installations
  • Warranty: Product-specific warranties
  • Financing Options: Cash payment, solar loans, power purchase agreements (PPAs)

Trinity Solar

Location: State of Maryland

What We Like: Trinity Solar has installing solar PV systems throughout the Northeast since 1996. As a family-owned operation, it builds its business upon the core values of integrity, reliability and impact. It offers high-quality panels along with multiple batteries and financing options.

What We Don’t Like: Trinity Solar does not offer a guarantee of your estimated savings in your contract as some other solar companies do. This can be problematic for customers choosing solar leases or power purchase agreements (PPAs). If you sign a lease and your panels don’t perform as advertised, you may not be able to cancel your contract or get your money back. Make sure to read the fine print.

What Customers Are Saying: “Have nothing but good things to say about Trinity Solar. Very professional installation with no problems three years out. Saving money and helping the environment with renewable solar energy. They also made good on their promise to reward me for making a referral to my neighbor who also joined the Trinity family.” — Carl via Google Reviews

Trinity Solar at a Glance:

  • Year Founded: 1994
  • Services Provided: Solar panels, backup battery installations; energy efficiency upgrades
  • Warranty: 25-year manufacturer, 5-year workmanship warranty
  • Financing Options: Cash payment, solar loans, solar leases, power purchase agreements (PPAs)

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:

  • Year Founded: 2009
  • Services Provided: Solar panels, backup battery installations, live energy monitoring
  • Warranty: Product-specific warranties ranging from 20-25 years
  • Financing Options: Cash payments, solar loans

SunPower

Location: State of Maryland

What We Like: SunPower has been an industry leader since 1985, manufacturing some of the best solar panels on the market. With nationwide service, SunPower can connect you with a certified dealer near your home or business to conduct the installation. 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

SunPower at a Glance:

  • Year Founded: 1985
  • Services Provided: Solar panels, backup battery and electric vehicle charger installations
  • Warranty: 25-year all-inclusive warranty
  • Financing Options: Cash payments, solar loans, solar leases
  • Learn More: SunPower Review

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

Celestial Solar Innovations at a Glance:

  • Year Founded: 2013
  • Services Provided: Solar panels, backup battery installations
  • Warranty: Product-specific warranties
  • Financing Options: Cash payments, solar loans

Edge Energy

Location: State of Maryland; Based in Beltsville

What We Like: A certified master dealer of SunPower solar panels in Maryland, you can trust that Edge Energy installs some of the highest-quality solar technology on the market. 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
  • Financing Options: Cash payments, solar loans

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 six 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 $9,695 after the 30% 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.
