Why Fairfax Homeowners Are Going Solar in 2026

If you’re a homeowner in Fairfax, Fairfax County, there’s never been a better time to go solar. Electricity rates from Dominion Energy have been climbing — the current average is 15.58¢ per kWh, and most Fairfax households pay around $175/month. That’s money going to the utility with nothing to show for it.

A typical Fairfax home needs a 11 kW system to offset most electricity usage. Over 25 years, that’s estimated savings of $48,000+ — before the 30% Federal Tax Credit (~$11,000 back).

Fairfax County runs Solar Co-op programs and supports community solar initiatives. The county’s larger homes with higher energy bills make solar particularly cost-effective.
