Is solar worth it in Washington DC?
Short answer for a typical Washington DC home: a reasonable payback if you'll stay put — roughly 10.7 years to break even after the 30% credit. Run your own bill through the calculator below.
Washington DC gets moderate sunshine — about 4.2 peak sun hours a day — and residential electricity runs around $0.16/kWh. For a typical $150-a-month power bill, that points to roughly a 9.2-kW system costing about $19,264 after the 30% federal tax credit, paying for itself in about 10.7 years and netting on the order of $42,101 over 25 years. Your own numbers will differ — the calculator above uses your real bill.
DC's standout is its SREC market — solar renewable energy credits here have been among the most valuable in the country, often dramatically shortening payback on top of the energy savings. Worth checking current SREC prices.
What changes the math in Washington DC
- Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Washington DC sits at about $0.16.
- Sun hours — more sun means a smaller, cheaper system covers the same usage. Washington DC averages ~4.2 hours.
- Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
- Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.
