Maryland has big plans with solar — in fact, the state actually plans to reach 100% clean and renewable energy by 2040. With that being said, now is the perfect time to jump on the solar system train. However, when it comes to professional installation, who are the best solar companies in Maryland that can save you money? Let’s talk about it.


SunPower, a company that was established in 1985, is renowned for producing some of the greatest solar panels and systems. They install solar photovoltaic (PV) panels, solar systems, batteries, and EV chargers. And, the BBB gives them an A+ rating.

The company has put in approximately 500,000 residential solar power systems in the US. And, they have a 25-year warranty on both the materials and labor, giving you peace of mind. However, SunPower is usually the more expensive option based on installation costs.

Trinity Solar

Trinity Solar was launched in 2004, so the company has been around for around 20 years. It’s also one of the top 10 largest solar companies in the US currently, with a BBB rating of A+.

Trinity Solar installs Qcells solar panels, SolarEdge inverters, and a variety of batteries, including from Tesla and Generac. All of these components come highly rated, and many have at least a 10-year manufacturer warranty. Trinity also offers their own 10-year workmanship warranty when you purchase your system and installation through them. The company claims that its systems costs are market-dependent, and customers have listed prices of $15k to $25k.


Sunrun is a bit of a newcomer on the solar installation scene, starting in 2009. But, the company has thousands of happy customers and an A+ rating on BBB.

A large perk for homeowners who want a solar system but don’t want to pay a lot of money upfront is that Sunrun has two solar leasing options. These leases allow you to get solar with $0 down and a 20-year solar warranty. Sunrun also offers a 10-year warranty for the roof in its installation contract, which is rare! Sunrun routinely monitors and maintains your system as part of its solar services once you’ve leased your system.

ADT Solar

ADT Solar has had a BBB rating since 2013 and has an A+ in the company’s system. Not only does the company offer solar installation, but they also offer a fully integrated smart home experience, which includes security monitoring and automating your home’s systems (including lights).

ADT delivers high-quality equipment in all of the company’s solar projects. This includes both Tesla Powerwall batteries and Enphase inverters. It also offers 25-year warranties for products and labor. Unfortunately, the company doesn’t offer leasing options, so you’ll have to buy your system outright. They’re also a bit more expensive, with some customers reporting around $25,000 for a system.

Edge Energy

Edge Energy offers renewable energy systems and solar systems in Virginia, DC, and Maryland. They are fully licensed, insured, and bonded (including their subcontractors). And while the company is not BBB accredited, they do have an A+ rating.

Unlike other companies on this list, Edge Energy uses one specific company for all of its system components. This helps them avoid supply chain issues that can hold up projects, as well as ensures the system is easy to install, affordable, and easy to repair. However, the system only has a 15-year warranty.

Lumina Solar

Lumina Solar is basically a brand new company, opening in Maryland in 2018. And even though the company isn’t BBB accredited, it does have a high rating of A+. The company currently services four states — Maryland, Virginia, Pennsylvania, and DC.

Lumina Solar makes a promise that they can install your entire system in just one day. They also have their own referral program, where you can get $500 for referring a new customer to them. They offer solar leases on much of their system, and also loans if you need one. The company offers 25-year warranties on panels and inverters. And, they offer a 10-year workmanship warranty on every installation. This comes along with a Solarinsure 30-year extended warranty if you choose that, which is one of the longest options that you can get out of the industry.

Solar Energy World

Solar Energy World is a solar installation company that provides services in Maryland as well as the nearby states of Virginia and DC. They are fully insured and state that they can install a full system in three days or less. They’re also the only company on this list that makes a donation to environmental organizations after each installation. They currently have an A+ rating on BBB.

Solar Energy World installs high-end components from Enphase and Silfab. They have a “Triple Platinum Warranty” which covers the parts and labor of your system for 30 years. The company doesn’t charge for site visits or labor-related expenses. They also have a roof warranty and will replace the roof if needed within ten years of solar installation, along with reinstallation of your solar panels.

How to Save Money When Hiring a Solar Company in Maryland

Now that we’ve talked about some of the best solar companies in Maryland, let’s talk about how you can save on the panels and installation costs.

Take Advantage of Rebates, Grants, and Promotions

First, you can save thousands on your installation costs by taking advantage of rebates, grants, and promotions. We’ve listed many different rebate programs below, but there are other ways to save too.

First, depending on how you pay (cash, credit card, etc), you may be able to get discounts. Also, don’t be afraid to talk to your potential installers about any promotions they may have to reduce costs.

Shop Around

Another way to save is to shop around and see what each company offers and the cost. Now, this is not to say that the cheapest company will be the best. But, if they have decent ratings, plenty of expertise, and give you the same solar system for a bit less, it can be helpful.

Ask for a Discount

While this may be hit or miss, it never hurts to ask for a discount! Does the company have a referral system? Can you save money by paying cash? What if you use their loan system? Asking for a discount can help you save hundreds if not thousands.

What to Consider Before Hiring a Company

Before you hire a solar installation company, there are a few key points to keep in mind.

Workmanship Warranties

It’s crucial to know whom to contact if something goes wrong with your solar panel installation. Your solar energy system should be backed by a number of warranties, including ones from the manufacturers of the panels and the installer’s craftsmanship.

The craftsmanship warranty can vary, but most are for one to ten years and are related to the job the installer completes. Ask your installer what is covered by the warranty, if there are any exceptions, and whether you would be responsible for any costs if they had to come out and inspect or replace your panels or equipment.

Potential Subcontractors

In some cases, the work involved in your solar installation will be handled in part or entirely by subcontractors. This is normal. However, an installer’s lack of candor regarding who will install your system and their use of subcontractors can be a problem.

Once you’ve narrowed your list to a few potential installers, be sure to ask whether the system will be installed by their own crew or by subcontractors. If they use subcontractors, find out why, and what they will complete, as well as their credentials.


It’s crucial to work with a solar installation with experience in the solar industry and who can specifically meet the demands of their clients, plus getting the necessary licenses and certifications.

The greatest installers will work with you to comprehend your demands and how solar will fit your needs. Make sure your solar installer has proven experience with solar installation as well.


While warranties and expertise are important, it’s also crucial to choose a company that takes care of its customers and keeps them happy. Take a look at their ratings and reviews. This will give you an idea of their craftsmanship and customer service.


Solar energy can have a fantastic return on investment, but the upfront cost is often fairly expensive. Solar systems can cost anywhere between $8,000 to $20,000, and sometimes even more.

Like any other home investment, the cost of solar should be a significant consideration, but keep in mind that the cheapest system is not always the best choice. So, find an installer who can provide decent warranties and products that fit your budget. Also, don’t be afraid to take advantage of grants and rebates!

Are Solar Panels Worth It in Maryland?

So, are solar panels worth it in Maryland? We’d say yes, due to all of the many benefits you can receive. Let’s discuss this below.

Inflation Reduction Act

With the Inflation Reduction Act (IRA), homeowners that meet the requirements and install solar panels on their homes may be eligible for a tax credit of up to 30% of the system’s cost.

Solar Energy System Property Tax Exemption

This tax exemption excludes the value that’s added when you install a solar panel system from your home’s value. This aids savings for tax purposes.

Residential Clean Energy Rebate Program

Also known as R-CERP, this rebate program helps Marylanders who both purchase and install a new solar power system. This rebate can earn them $1,000 if they qualify.

The Federal Solar Tax Credit

Along with the state’s programs and grants, you can still qualify for the federal Solar Tax Credit. With this credit, you can get a 30% discount on the price of your solar system. You’ll need to have sufficient income for the tax credit to be relevant, and this credit only applies to those who purchase their system outright — either with a cash purchase or a solar loan.
