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 are many factors to take into account when choosing the best solar installer for your home. For instance, you need to take into account where you live, your utility company, the rooftop space on your property and how much energy you use. You might want to consider some of the following factors when deciding what’s most important for choosing one Maryland solar installer over another.

Services Offered

Solar installation companies in Maryland will differ from company to company since they each offer different services and are more specialized than others. Examples of companies that focus strictly on solar panels: Maryland Solar Solutions. Examples of companies that prioritize efficiency and home energy upgrades but use solar panels as a supplement: Edge Energy. Consider what makes your home or business unique. And then look for a company that is capable of working with these particular needs. Some other things to think about could be whether you need roofing work, EV chargers or backup power systems.

Solar Pricing and Financing

There is no denying that Maryland’s home solar installation market has exploded. It doesn’t matter if you have an average credit score or not. There are plenty of different financing options to be had to help you make solar part of your life. Maryland is full of experienced solar installers who know the difficulties of high upfront costs, so make sure to ask about flexibility in financing options.

Industry Affiliations

Companies who earn industry credentials, such as from the Solar Energy Industries Association (SEIA), B Corp certification or affiliations with other professional associations, are usually worth the investment. When you work with a company that is certified and has memberships, it means that they are reputable, reliable, and trustworthy.

Types of Panels

Some solar panels are better than others, so make sure you do your research and find out what the installer has to offer. For small homes in confined areas, high-efficiency solar panels will likely be a necessity. However, commercial projects with more space may prioritize the most affordable panels. It’s worth asking what brands of panels your company is certified to sell and install. Depending on the quality of certification that they have attained from a respectable solar panel brand, such as Tesla, Panasonic, LG or REC, this is also an indication that they are one of the best.

Incentives, Rebates and Tax Credits

Maryland offers some of the most competitive solar incentives in the country. They’re great for helping you get the equipment you need, but it’s important to do your research to find a installer that knows how to get the best value from Maryland’s current solar incentives. It’s worth looking locally when hiring a company. Does the company you’re looking at have plenty of experience working in your community?


Most warranty issues with solar boil down to the level of quality installation, not the panels. We recommend getting a company with a good installation guarantee or warranty that covers any potential issues with your roof or home in case they occur years after installation. It’s prudent to choose a reputable solar company that provides at least 10-year warranties.

Cost of Solar in Maryland

As of 2022, the average cost for solar in Maryland is around $2.77 per watt. That means a 5-kW system costs around $9,695 after the 30% federal tax credit is applied. Think of a 5kW solar system as the minimum size you need for your home.

Although it can be difficult for those in Maryland to switch to clean energy, the state offers plenty of incentives to help incentivize the switch. Visit DSIRE for more information on available subsidies at this location.

How to Find the Best Solar Installer in Maryland

Maryland provides a renewable energy incentive structure that’s very different to other states. This is great, as it makes Maryland stand out due to the SREC, grant and tax exemptions it offers. However, this can be both good and bad, because these are hard to implement in your business and confusing at first. This is why you need to find a solar company with incentives experience & a proven track record of getting customers the best return on investment in solar.

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