Request Washington D.C. solar quotes
Ready to compare Washington D.C. 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 9 Washington D.C. solar companies on licensing, warranties, local presence, track record and options. The top three: Solar Energy World (5, Top-rated), Sunrun (4.5, Excellent) and Solar Solution (3.5, Good).
- Pepco credits exported power kWh for kWh, but power above 100% of your yearly use is paid only at the generation rate each December. The SREC income goes to whoever your contract names.
- DLCP licenses contractors in DC. Ask for the company’s Home Improvement Contractor license number and the DC master electrician who supervises the electrical work; DLCP’s electrician search needs a sign-in.
What solar costs in Washington D.C.
There is no upfront rebate to subtract for most buyers; the District’s value arrives as income. The federal credit ended December 31, 2025. 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: Washington D.C. solar panel prices.
Solar incentives, tax breaks and rebates in Washington D.C.
- SRECs
- A home system earns one SREC per 1,000 kWh. The Public Service Commission reported a price of around $370 in mid-April 2026, and your contract decides who sells them.
- SREC price cap
- The legal cap is $440 per SREC for 2026 and $420 for 2027. It falls to $300 in 2033 and $100 in 2042.
- Net metering
- Pepco credits extra solar power kWh for kWh on a later bill. Each December, power above 100% of your yearly use is paid at the generation rate only.
- Solar for All
- For households at or below 80% of area median income. Free rooftop systems are on a waitlist; free community solar credits are worth about $500 a year for up to 15 years.
- Taxes
- No District income tax credit for home solar. Solar systems are exempt from the personal property tax, and the federal credit ended for systems installed after December 31, 2025.
- Association rules
- Since July 17, 2018, a condo, co-op or homeowners association cannot ban solar on your own property or on a roof that covers only your unit.
Who qualifies, deadlines and sources: Washington D.C. solar incentives.
What to check with your utility
Pepco
- Extra solar power comes off a later bill kWh for kWh, and credits carry over month to month.
- Each December, power above 100% of your yearly use is paid at the generation rate only; a credit over $25 is refunded.
- A home system can be sized up to 200% of your past year of use, but the monthly customer charge stays on the bill.
DC SREC market
- The PSC reported around $370 per SREC in mid-April 2026. The cap is $440 for 2026 and falls $20 a year to $300 in 2033.
- Only a PSC-certified system earns SRECs, and production must be reported in GATS at least twice a year.
- On a lease or PPA, read the SREC clause: the company that owns the panels can keep them.
Solar for All
- For households at or below 80% of area median income, or on a federally approved assistance program.
- Free rooftop applications go on a waitlist until further notice; DCSEU had posted no terms for the new budget year.
- Do not sign a solar contract while you wait: a signed contract makes the home ineligible.
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 DC Department of Licensing and Consumer Protection (DLCP) Basic Business License with a Home Improvement Contractor or General Contractor/Construction Manager endorsement. DLCP's Board of Industrial Trades licenses electricians and electrical contractors.. The name must match your contract.
- Electrical connection: DLCP's Board of Industrial Trades licenses electricians, and a licensed electrical contractor must name a DC-licensed master electrician who supervises its work (https://dlcp.dc.gov/sites/default/files/dc/sites/DLCP/publication/attachments/Trade%20Contractor.pdf). 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 Washington D.C. 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.

How we rate Washington D.C. solar companies
Each company gets up to 100 points from facts anyone can check: its own website and Washington D.C.’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 Washington D.C. and Washington D.C. 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.
Washington D.C. solar company FAQs
How do I check a DC solar installer's license?
Ask for the company’s DLCP Basic Business License number with its Home Improvement Contractor or General Contractor endorsement, and check its status and end date in DLCP’s records. DLCP says home improvement contractors need a Home Improvement Contractor license. Also ask who the DC-licensed master electrician on your job is.
Does Washington, DC have net metering?
Yes. Pepco credits extra solar power kWh for kWh on a later bill, and credits carry over month to month. Each December, power above 100% of your yearly use is paid at the generation rate only, and Pepco refunds a credit of more than $25. The monthly customer charge stays on your bill.
How much is a DC SREC worth in 2026?
The Public Service Commission reported a price of around $370 per SREC as of mid-April 2026. The legal cap is $440 for 2026 and $420 for 2027, and it falls to $300 in 2033. The price moves with the market, so ask which price a quote uses for each year.
Is DC Solar for All taking new households?
Partly. It serves households at or below 80% of area median income. Free rooftop applications go on a waitlist until further notice, and DCSEU had posted no terms for the new budget year when EcoGen checked. Free community solar enrolls income-verified households when a project has room.
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.
