Is solar worth it in District of Columbia?
At District of Columbia’s average rate of 22.3¢/kWh and about 1300 kWh per kW of panels a year, a typical home pays back its system in roughly 9.5 years on electricity savings alone — no federal credit, which ended for buyers at the end of 2025 — then keeps saving. Run your own numbers below.

What drives solar payback in District of Columbia
District of Columbia homeowners pay about 22.3¢/kWh, which is 3.9¢ above the national average. A rooftop here generates roughly 1300 kWh per kW each year — about the typical US figure. On exports, District of Columbia offers full retail net metering: Among the most valuable SREC markets in the country, which can sharply cut payback.

A worked example
For a District of Columbia home with a $195/month power bill (typical household usage at District of Columbia’s rate):
That nets out to a payback of about 9.5 years — shorter than simply dividing net cost by year-one savings, because power prices climb ~2.5%/yr so your savings grow each year. Assumes 3.00 $/W installed before incentives and a typical 40% self-consumption; your actual cost, roof and usage will differ — adjust the calculator above.
Who supplies your power in District of Columbia
The District is served by a single electric distribution utility: Pepco (the Potomac Electric Power Company), which delivers power to essentially every home in DC. Because there is only one wires company and one set of District-wide rules, your net-metering terms, interconnection process and incentive eligibility are the same wherever you live — from Georgetown to Anacostia. DC's retail electricity market is technically deregulated, so you can choose a competing supplier for the generation portion of your bill, but Pepco remains the utility that reads your meter, handles interconnection and applies your net-metering credits regardless of who supplies your electrons.
What you’re paid for what you export
District law keeps net metering at the full one-for-one rate: exported kilowatt-hours earn exactly what you pay for imported ones, and unused credits carry forward month after month, indefinitely, against future consumption. Any balance still standing at the annual true-up is settled at the utility's generation (avoided-cost) rate rather than retail, which is the one reason not to deliberately overbuild — match the system to your own usage. There is no District-wide capacity cap on net metering, and a normal rooftop array sits comfortably inside the eligible size limit. While California has moved to slashing export values, DC still lets the grid work as a near-perfect one-for-one credit bank.
District of Columbia incentives & taxes in 2026
Own a solar roof in the District and you hold some of the most valuable renewable-energy certificates in America. DC's Renewable Portfolio Standard carries a large and rising solar carve-out backed by steep compliance penalties — the solar alternative compliance payment — which has historically kept DC SREC prices at or near the top of the national table. A typical home system mints several SRECs a year, and that income by itself can shorten payback dramatically. Lower-income households have a further route: Solar for All, which can cover much or even all of an installation. SREC values and programme eligibility move with policy, so confirm the current numbers before building them into your plan.
The 30% federal credit ended on 31 December 2025 and can now only reach a homeowner indirectly through a lease or PPA. Check the current state and utility programs on DSIRE’s District of Columbia list, then type any incentive into the calculator above to see how it shortens your payback.
What solar costs in District of Columbia
Row-house roofs make DC pricing idiosyncratic: tight rooftop access, shading from the neighbours and dense urban permitting feed into quotes of roughly $2.90 to $3.40 per watt — a touch more than the typical American install — and mean estimates vary more here than in open-lot suburban markets. A standard residential system ends up in the low-to-mid five figures before incentives. The consolation is that SREC income carries most of the payback load anyway.
The honest verdict for District of Columbia
One market makes the District's case: SRECs. Policy-backed certificate prices near the top of the national table, stacked on one-for-one retail crediting, can offset a large share of system cost and keep payback competitive despite dearer-than-average installs and only middling sunshine. The caveat is the same as the strength — SREC values ride on market and policy, so count them as strong rather than guaranteed. If you own a suitable roof in the District, solar in 2026 still stacks up better here than in most states.
