What solar costs and returns here
EnergySage data put average Falls Church pricing at $2.41 per watt in June 2026, or $30,328 for an average 12.57 kW system before incentives. It reports that homeowners who buy upfront break even after about 10.5 years on average.
Most of that value comes from net metering: the Virginia SCC's April 2026 order kept Dominion's one-to-one annual netting, with year-end surplus cashed out at the lower avoided-cost rate, so we size to your yearly usage.
