Washington, D.C. runs the richest solar incentive stack in the country, and almost none of it is a tax credit: the money is in solar renewable energy certificates that have traded at $360 to $400 each, stacked on Pepco’s full-retail net metering, with a genuine free-installation program underneath for income-qualified households. A typical 7 kW system mints about 8 certificates a year, roughly $3,000 of income before a single bill credit. Here is what each layer pays in 2026, who will not qualify, and the paperwork that decides who actually collects.
The Certificate Stack: How D.C. Pays Roughly $3,000 a Year
The District’s renewable portfolio standard forces utilities to buy local solar certificates, and scarce D.C. rooftops keep the price extraordinary. SRECs have traded at $360 to $400 against a $440 compliance ceiling, while most states’ certificates fetch under $50. Every megawatt-hour your system generates creates one certificate, so a 7 kW row-house array produces about 8 a year, worth roughly $2,900 to $3,200 at current trades.
For programs beyond Washington DC, our solar incentives nationwide covers every state.
Two caveats belong next to that number. Certificates only pay once your system is registered and the certificates are sold, directly through the PJM tracking registry or through an aggregator that takes a fee. And prices ride the compliance market: they have stayed high because District supply is scarce, but the $440 ceiling is a cap, not a promise. Model income at current trades and stress-test lower before you borrow against it.
Pepco’s Full-Retail Netting Under the Certificates
Beneath the SREC headline sits ordinary good policy: Pepco credits exported energy at your full retail Pepco rate, one-to-one against your usage. No successor tariff is pending, no export haircut, no time-of-use gymnastics. Combined with certificate income, the netting routinely repays District systems faster than anywhere in the country.
What Each Layer of the D.C. Stack Pays in 2026
Incentive Layer | What It Pays | Who Gets It | The Catch |
|---|---|---|---|
SREC sales | ~$2,900-$3,200/yr on 7 kW | Whoever owns the certificates | Must be registered and sold; prices move with the compliance market |
Pepco net metering | Your full retail Pepco rate, 1-to-1 | Every interconnected system | Credits reduce your bill; they do not pay out as cash |
Solar for All | Installation covered outright | Households at or below 80% of area median income | FY2026 applications waitlisted |
Federal residential credit | $0 | Nobody, since December 31, 2025 | Quotes still showing it are out of date |

Solar for All: The District’s Genuine Free-Install Program
Through the DC Sustainable Energy Utility, Solar for All covers installation outright for households at or below 80% of area median income. Demand is real: FY2026 applications sit on a waitlist. Apply anyway; cohorts cycle, and if you qualify, joining the waitlist should come before paying for anything the program might cover. Renters and condo residents can also benefit through the program’s community solar component, which credits participating households without touching their roof.
The Paperwork That Decides Who Collects
When a roof earns $3,000 a year, contract language is money. Leases and some purchase contracts quietly assign certificates to the installer; in the District that single clause moves thousands a year. Before signing anything, find the SREC clause and confirm it names you as owner along with the registration path, or prices the assignment as a genuine, visible discount. Then ask who files the registration, what the aggregator’s fee is, and get the answer inside the contract rather than a conversation.
You Likely Won’t Qualify for the Full Stack If…
- You rent or don’t control the roof. The SREC and netting layers follow roof ownership. Community solar through Solar for All is the workable route instead.
- Your household is above 80% of area median income. Solar for All is closed to you; the SREC stack and netting still are not, and they carry most of the value anyway.
- Your roof is heavily shaded. Neighboring buildings and mature street trees cut production no certificate price rescues. A site study comes before any incentive math.
- You sign a contract that assigns your certificates. You will technically have solar and practically have given away the District’s best incentive.
- You are waiting on a tax credit. The federal residential credit ended for systems whose installation is completed after December 31, 2025, and the District’s stack never depended on it.
Certificate income is the piece most D.C. quotes get wrong, in both directions. Enter your ZIP code and we will estimate what your roof’s certificates are worth at current market prices.

Frequently Asked Questions
What are Washington, D.C. SRECs worth in 2026?
D.C. SRECs have traded at $360 to $400 each against the District’s $440 compliance ceiling, the highest certificate prices in the nation by a wide margin. A typical 7 kW system produces about 8 per year, roughly $2,900 to $3,200 of annual income. Prices move with the compliance market, so model at current trades and stress-test lower before borrowing against them.
Is there still a solar tax credit in Washington, D.C.?
Not for homeowners who buy their system. The federal residential credit ended for systems whose installation is completed after December 31, 2025, and the District offers no local solar tax credit. Third-party owners such as lease and PPA companies can still claim a separate business credit (48E), which should show up as better lease pricing. D.C.’s stack never depended on tax paperwork: the value flows through certificate sales, full-retail net metering, and, for income-qualified households, Solar for All.
Do I qualify for Solar for All in D.C.?
You qualify for Solar for All if your household income is at or below 80% of area median income; the program then covers installation outright through the DC Sustainable Energy Utility. FY2026 applications are waitlisted, so join the list before paying for anything the program might cover. Renters can participate through the community solar component.
