Solar panels in Fairfax, VA

What Fairfax homeowners are paying

There is no average price for solar in Fairfax. What Fairfax homeowners are paying comes down to their Dominion bill size, their roof, and whether they are buying outright or on a Virginia Solar Lease.

What we see: Fairfax single-family homes tend to fall in the mid-size system range. Townhomes often fall below. Larger homes with heat pumps, EVs, or pools push into larger systems. We price every proposal against your actual twelve-month Dominion usage, not a per-square-foot rule of thumb.

Most Fairfax homeowners who go solar with us use our Virginia Solar Lease: zero down, fixed monthly payment below their current Dominion bill, with a production guarantee built in. It is not the only path, but it is the one that protects against both up-front cost and long-term rate uncertainty.

How Fairfax sun hours affect your savings

Fairfax gets enough sun to make solar work across almost any well-exposed roof. Production varies month to month, peaking in late spring through early fall and dipping in late fall through winter. Your system is sized to cover your full-year usage, so winter dips are balanced by summer surplus that banks as net metering credits.

Fairfax gets reliable annual sun, and the mix of wider suburban lots (in parts of the county) gives many homes good southern exposure. Mature tree canopy in established neighborhoods is something to design around rather than ignore.

Dominion Energy net metering for Fairfax

Every Fairfax residential customer we serve is on Dominion Energy. When your panels produce more than your home uses, the surplus flows back to the Dominion grid and your meter records credits. At night or on cloudy days, you draw from the grid and use those credits. Net metering is the mechanism that lets a well-sized Fairfax system zero out most of your electric charges across a full year.

Virginia net metering rules are set at the state level and have evolved over time. We walk through the current version when we put your proposal together, so you know exactly how your credits flow.

Local permitting and timelines in Fairfax

Fairfax County has one of the more rigorous residential solar permitting processes in Virginia. Engineering documentation, detailed roof plans, and structural review are often required. This is a feature, not a bug: rigorous review means fewer surprises later. We are experienced with the Fairfax County process and factor it into your timeline.

A normal Fairfax install, from signed contract to the day your meter starts turning backward, takes a few weeks to a couple of months depending on utility interconnection queue and any county or HOA review. We give you a realistic timeline up front. If something slips, we tell you.

Virginia incentives available to Fairfax residents

Fairfax homeowners qualify for the same stack of Virginia incentives: net metering through Dominion, a local property tax exemption where adopted, SRECs if you own your system, and PACE financing where available in the jurisdiction.

Solar incentives change year over year. We keep current and walk through what is actually available for your specific Fairfax address when you request a quote.
