The demand for solar energy in Washington D.C. has never been higher. Rising utility costs and strong local incentives make now the perfect time for homeowners to consider installing solar panels. But one of the first questions most homeowners ask is: “What is the cost of solar panels in D.C.?”
The answer depends on a variety of factors—system size, equipment, installation costs, and available rebates. Let’s break it down.
Average Solar Panel Installation Costs in D.C.
The cost of solar panels in D.C. typically ranges from $12,000 to $20,000 for residential systems before incentives. The exact amount depends on your energy usage, roof size, and the quality of panels you choose.
High-efficiency panels like 400-watt solar panels are becoming popular because they generate more power per square foot, making them ideal for urban homes with limited roof space.

- Federal Investment Tax Credit (ITC): Covers 30% of system costs.
- Local rebates and incentives: D.C. provides some of the strongest incentives in the U.S.
- SREC market: Homeowners can earn money for every 1,000 kWh their system generates.
