Request Maryland solar quotes
Ready to compare Maryland prices?
Enter your ZIP code to ask solar providers that serve your area for quotes. Compare each quote with the checklist below.
Solar providers that serve your area may contact you, and they pay EcoGen for the introduction. Providers can include installers, solar marketplaces and lead exchanges, and more than one may contact you. How we make money.
Need to know
- We rated 8 Maryland solar companies on licensing, warranties, local presence, track record and options. The top three: Solar Energy World (5, Top-rated), Trinity Solar (5, Top-rated) and SunnyMac Solar (4, Very good).
- Every Maryland utility credits exported power kWh for kWh. That deal closes to new homes on July 1, 2027, or sooner if the 3,000 MW limit fills, and a home connected before then keeps it.
- Maryland requires a licensed home improvement contractor (MHIC) to mount the panels and a licensed electrician to connect them. Ask for both numbers; the state’s online search now requires a human check.
What solar costs in Maryland
No federal credit for systems you buy in 2026. Maryland’s 6% sales-tax and property-tax exemptions still apply. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.
Source: EcoGen Solar Cost Index, September 2026 Edition, prices as of September 25, 2026. Full breakdown: Maryland solar panel prices.
Solar incentives, tax breaks and rebates in Maryland
- Net metering
- Each kWh you send to the grid cancels one kWh you buy. It closes to new homes on July 1, 2027, or sooner if the state limit of 3,000 MW fills; a home that is in before then keeps it.
- State rebate
- The Maryland Solar Access Program pays $750 per kW, up to $7,500, to households at or below 150% of the state median income ($195,375 for four people). Reserve it before the install, by May 31, 2027.
- SRECs
- One certificate per 1,000 kWh, about 11 a year for a typical 7.78 kW system. A market sets the price; the supplier fee it tracks is $45 in 2026 and $35 in 2027.
- SREC bonus
- Systems of 20 kW or less switched on between July 1, 2024 and January 1, 2028 can be certified under the Brighter Tomorrow Act, so each certificate counts 1.5 times, within the first 300 MW.
- Battery grant
- State law caps it at 30% of the installed cost or $5,000, whichever is lower. Reserve before the battery goes in; apply by May 31, 2027.
- County credits
- Five places take money off one property tax bill, for example up to $2,500 in Anne Arundel County and $5,000 in Baltimore City.
- Taxes
- No 6% sales tax on solar equipment and no property tax on it. Maryland has no state income tax credit for solar, and the federal credit is $0 for home systems finished after December 31, 2025.

What to check with your utility
BGE
- Its volumetric rate is 21.10¢ per kWh, and a BGE interconnection costs $100 to $150.
- The fixed monthly customer charge stays on the bill even when your panels cover all your use.
- A January 2026 review found weeks-long waits for permission to operate. Ask how long recent BGE jobs waited.
Pepco
- Its volumetric rate is 19.76¢ per kWh, and the fixed monthly customer charge stays on the bill.
- Some homes near Washington, D.C. are on lines tied to the D.C. grid and cannot get the state rebate. MEA links a Pepco map to check.
- The same review found weeks-long waits for Pepco permission to operate.
Delmarva Power
- Its volumetric rate is 21.51¢ per kWh, the highest of the four.
- Leftover credits are paid out after April at the lower generation rate by default; you can choose instead to roll them forward with no end date.
Potomac Edison
- Its 14.88¢ rate is the lowest in the state, so payback runs well past the 9.3-year best case.
- Weigh it harder if you may move within five years.
SREC market
- No state office publishes a price. Treat SREC income in a quote as an estimate and ask which year's price it uses.
- After switch-on, certify the system at pscrec.com ($50) and answer yes to the Brighter Tomorrow question.
- With a lease or PPA, the company usually keeps the SRECs.
Check the company and its warranty
Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.
- Contract company: look up its license on the Maryland Home Improvement Commission (MHIC) contractor license, Maryland Department of Labor. The State Board of Master Electricians licenses master electricians, and a local license is also required.. The name must match your contract.
- Electrical connection: The MHIC says solar panel systems must be mounted by a licensed home improvement contractor, and the person who connects them to the electric box or the grid must hold an electrician's license issued by the local jurisdiction (https://www.labor.maryland.gov/license/mhic/mhicgreen.shtml). Ask who does it.
- Warranty documents: ask for the workmanship warranty, the roof coverage terms and each equipment warranty before you sign.
Before your first sales call, read questions to ask your solar installer and how to read a solar quote.
Compare your Maryland quotes
Ask every company to quote the same basics. Then the differences you see are real.
From quote to permission to operate
Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.
Proposal and site check
The installer looks at your roof, shading and electrical panel and gives you a written proposal.
You and the installerDesign and applications
After you sign, the installer finishes the design and applies to your utility for the connection.
Installer; you sign the formsPermits and utility review
Your town or county reviews the building and electrical permits. The utility reviews the connection.
Permit office and utilityInstallation and inspection
The crew installs the system. A licensed electrician connects it, and the inspector checks the work.
Installer crew, electrician and inspectorPermission to operate
The utility approves the system and updates your meter if needed. Turn the system on only after this step.
Utility
How we rate Maryland solar companies
Each company gets up to 100 points from facts anyone can check: its own website and Maryland’s public license records, read October 14, 2026. Facts a company does not publish earn no points. No company pays for its rating, and we do not use customer star reviews.
- Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
- Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
- Local presence (15 points): an office in Maryland and Maryland named as a service area.
- Track record (10 points): years installing solar.
- Options (10 points): batteries and the number of ways to pay.
Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.
Maryland solar company FAQs
How do I check a Maryland solar installer's license?
Ask for the company’s Maryland Home Improvement Commission (MHIC) number and check it in the Maryland Department of Labor license search, which now asks for a human check. The MHIC says panels must be mounted by a licensed home improvement contractor and connected by a licensed electrician, so ask for that license too.
Does Maryland still have net metering?
Yes. Each kWh you send to the grid cancels one kWh you buy, under Public Utilities Code § 7-306. A 2026 law closes this to new homes on July 1, 2027, or sooner if net-metered systems reach 3,000 MW. A home under a net metering contract on that date keeps it.
How much is the Maryland solar rebate?
The Maryland Solar Access Program pays $750 per kW of system size, up to $7,500, to households at or below 150% of the state median income. You must reserve it before the install, use a contractor on MEA’s list, and apply by May 31, 2027, or sooner if the $10 million budget is requested.
Who keeps the SRECs with a lease or PPA?
Usually the company that owns the system. If you buy, the SRECs are yours to sell: one is issued for every 1,000 kWh your panels make, about 11 a year for a typical system. No state office sets the price, so treat SREC income in a quote as an estimate.
Will the companies on this page contact me?
Not because they appear here. This page is an editorial comparison. If you request quotes, the providers that serve your area may contact you. They can include installers, marketplaces and lead exchanges. Our page on how we make money explains how EcoGen is paid.
