Washington, D.C. quietly runs the best rooftop solar economics in America: a typical 7 kW system mints about eight renewable energy certificates a year that trade at $360 to $400 apiece, roughly $3,000 in annual income before a single bill credit. Add Pepco's full-retail net metering and the District becomes the rare place where panels earn their keep. EcoGen America shows the row-house math in full.

D.C.’s renewable portfolio standard forces utilities to buy local solar certificates, and scarce District rooftops keep the price extraordinary: SRECs have traded at $360 to $400 against a compliance ceiling of $440, while most states’ certificates fetch under $50. A 7 kW row-house system produces roughly eight a year, near $3,000 of income before bill savings.
Under it sits ordinary good policy: Pepco credits exports at the full retail rate, roughly 13 to 15¢, one-to-one. Stacked, SRECs plus netting routinely repay District systems faster than anywhere in the country.
Income-qualified households at or below 80% of area median income can pursue Solar for All, which covers installation outright, though FY2026 applications sit on a waitlist from demand.
EcoGen America verifies SREC registration paths, prices quotes against District rates, and matches you with installers who know row-house roofs and DCRA permitting cold.
Every installer we list works D.C. permitting, historic-district review and row-house roofs weekly, not occasionally.
Built-in checks for SREC assignments hiding in contracts, undersold certificate income and dealer fees inside financed totals.
SREC prices move with the compliance market. We model at current trades, not last year's highs.
Your information goes only to the installers you choose to hear from. Nothing is resold.
EcoGen is 100% free for homeowners. We earn a small referral fee from installers only when you choose to proceed with a project through our platform.
This fee comes from the installer’s marketing budget and does not increase your system price. In fact, our pre-negotiated rates often save you money compared to going direct.
No other American rooftop math looks like this. Here is a typical 7 kW District system, itemized.
Income Line | Roughly What It Pays | The Mechanics |
|---|---|---|
SREC sales (~8/yr) | ~$2,900 – $3,200/yr | Certificates trade at $360-$400 against a $440 compliance ceiling; register and sell via the tracking registry or an aggregator |
Net metering offset | Full retail, ~13-15¢/kWh | Pepco credits exports one-to-one against your usage |
Combined effect | Among the fastest paybacks in the U.S. | Certificate income alone can cover a third or more of system cost over its early years |
The corollary: in D.C., who owns the SRECs is the most valuable clause in the contract. A lease or PPA that keeps them is quietly keeping thousands a year.
Own your SRECs. In the District that single contract clause is worth roughly $3,000 a year on a typical system.
Certificates only pay once registered and sold, directly or through an aggregator. Who files, and their fee, belongs in the contract.
Row-house roofs, historic districts and DCRA process reward installers who do this weekly. Ask for recent District references, not regional ones.
Free 15-minute call. Certificate income, netting, permitting path, real total.
The SRECs headline, but the District’s supporting programs matter, especially for income-qualified households.
Between the certificates, the netting and Solar for All, the District has built the country’s most complete solar economics. The paperwork, as ever, decides who actually collects.
DC Contract Checks
When a roof earns $3,000 a year, contract language is money. Read these lines twice.
Leases and some purchase contracts quietly assign certificates to the installer. In D.C. that clause moves thousands a year.
Income at $400 per certificate is today's market, not a guarantee. A sound projection shows lower-price scenarios too.
Historic review and row-house structural quirks stall out-of-town crews. Recent District installs are the credential.
Strong economics attract creative financing. The cash anchor keeps the comparison clean.
Four clauses, any District quote. Native installers answer them without flinching.
Vetted for DC licensing, SREC fluency, permitting record and complaint history.
Even the country’s best math has exceptions inside the Beltway.
Everyone else with sun: move deliberately, keep your certificates, and District arithmetic does the rest. When you are ready for bids, start with the top solar companies in Washington DC.

Certificates have traded at $360 to $400 against the District’s $440 compliance ceiling, the highest in the nation by a wide margin. A typical 7 kW system produces about eight a year, roughly $3,000 of income.
Prices ride the compliance market; model at current trades and stress-test lower before borrowing against them.
Yes: Pepco credits exports at the full retail rate, roughly 13 to 15¢ depending on rate class, one-to-one against your usage.
Stacked under the SRECs, it makes District paybacks the fastest in the country.
A DCSEU program covering installation outright for households at or below 80% of area median income. Demand runs high; FY2026 applications are on a waitlist.
If you qualify, join the waitlist before paying for anything the program might cover.
Because the certificates are the value: thousands per year on an ordinary roof. Leases and some purchase agreements assign them to the company by default.
Read the clause, keep your certificates, or make the assignment show up as a genuine price discount.
