We’ve heard from over 100,000 verified solar customers since 2018, including dozens in Maryland.
A couple of things we know for sure: People like powering their homes with a reliable source of cheap, clean energy. They don’t like getting into solar contracts that don’t meet their expectations.
Here’s what to expect and what to look out for when buying solar panels in Maryland.
In Maryland, a typical residential solar panel system costs $9,323 to $26,372, depending on the size of your system and what financial incentives you qualify for.
Jump to insightThe federal solar tax credit expires soon. You have until Dec. 31, 2025, to install a system and get the 30% solar tax credit.
Jump to insightMany solar customers are happy with the service, installation and cost savings. Others felt misled by pushy sales tactics and ended up with monthly bills higher than expected.
Jump to insightSolar panels are a long-term investment — most systems last 25 years or more. That means choosing the right installer is just as important as choosing the right equipment.
Based on our research, the best solar energy companies share a few traits: strong customer reviews, high-quality equipment and reliable warranties. Here are the five steps to finding the right fit.
Local experience matters. Companies with a history in Maryland understand state-specific incentive programs, utility rules, permitting requirements and how to design systems that perform well in the occasionally snowy winters and warm, humid summers.
Look at reviews on platforms like ConsumerAffairs, Better Business Bureau and solar-specific forums to see real customer experiences. Watch out for these red flags:
Get at least three solar quotes to compare prices, equipment, warranties and services. Be cautious of unusually low bids — they may signal poor-quality panels, hidden fees or weak warranty coverage.
As you’re getting quotes, consider if you want a solar storage battery, an electric vehicle (EV) charger or a monitoring system to ensure optimal output. It’s also smart to ask about critter guards in Maryland.
Solar installation companies have to be licensed as home improvement contractors with the Maryland Home Improvement Commission.
And if the solar panels connect to your electrical system or the power grid, a licensed electrician has to do that part. Confirm your installer also has:
The contract should be easy to understand. If anything about payment schedules, warranties, monitoring services or system maintenance doesn’t make sense — ask for clarification.

Average solar panel costs in Maryland typically range between $9,323 and $26,372. The size of your solar panel system is a big factor in your total cost. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets.
The table below doesn’t include the cost of a solar storage battery. Adding a battery to your system can increase your overall system costs by $7,000 to $18,000.
Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Maryland, the average cost per watt is $2.64.
Average solar panel costs by system size in Maryland
| 5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
|---|---|---|---|---|---|---|
| Before federal tax credit | $13,186 | $15,823 | $18,460 | $21,097 | $23,735 | $26,372 |
The federal solar investment tax credit (ITC) is now set to expire at the end of the year, much earlier than previously scheduled. The credit was expected to drop gradually, then fully expire in 2035 — but those future step-downs have been eliminated as of July 2025.
The ITC expired at the end of 2025.
This means you have until Dec. 31, 2025, to install and pay for a system in order to qualify for the 30% credit.
On the bright side, Maryland also has additional tax incentives and rebates. For example, homes with solar can get property tax credits and exemptions for the value the solar equipment adds to their homes.

The general consensus is that solar panels are worth it in Maryland. On average, homeowners can avoid $75,628 in total utility costs over 25 years.
We’ve talked to dozens of Maryland residents who have gone solar. Many reported significant savings on their electricity bills after installing solar panels.
Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.
For example, Rebecca in Baltimore said she likes getting cheap bills from Delmarva Power since installing solar panels: “It's definitely worth it. It's crazy how much money we're saving already.”
However, we’ve also heard about problems with leaks and roof damage. For instance, Roger in Aberdeen, who was overall happy with his decision to go solar, told us, “I was very unsatisfied with the time it took to both remove the panels and then put them back when I had my roof replaced.”
The return on investment of a solar panel installation depends on the efficiency and size of your system. Assuming an upfront purchase, it takes about 9.84 years to break even (when your savings with solar panels make up for the cost).
It's definitely worth it. It's crazy how much money we're saving already. ”
Getting solar panels is similar to buying a car. You could pay cash, but many people finance their system through a solar loan. If you have enough savings to pay upfront, the biggest advantage is no interest charges.
Leasing solar equipment is an attractive option for people who don’t want to get a loan or be responsible for maintaining a system.
Maryland also has legalized power purchase agreements (PPAs), unlike many other states. PPAs work very similarly to leases. The biggest downside to both is that you’ll be disqualified from many of the best financial incentives, like the 30% federal solar tax credit. It also might make your house harder to sell since a new buyer will have to take over the lease agreement.
» SOLAR PANELS: Lease vs. buy
Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Solar photovoltaic (PV) technologies, more commonly known as solar panels, absorb sunlight and convert it into usable electricity. If you have a lot of shading around your house, they might not get enough sun to power your home.
It’s also smart to upgrade any old, inefficient appliances first. Reducing your electrical loads now means you can get a smaller system, which will be cheaper.
Use the National Renewable Energy Laboratory’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house — just type in your address. Project Sunroof is a free solar savings estimator powered by Google Earth imagery.
» STILL NOT SURE? Solar energy pros and cons
As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This will cost around $5,000 for a 19-panel setup.
» SHOULD YOU: Replace your roof before going solar?
We are not aware of any legitimate programs for free solar panels in Maryland. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can end up costing you quite a bit of money.
» FREE SOLAR PANELS: Are they really free?
Net metering lets homeowners get credits for extra electricity their solar panels generate. Your solar panels convert sunlight into electricity that powers your home first. Any excess electricity your panels generate flows back into the grid.
In Maryland, systems eligible for net metering must be less than 2 megawatts (MW) in capacity or 200% of your annual baseline electricity. Each month, you are still billed for the net difference between your electricity usage and the amount you generate:
