Herndon is a historic Town within Fairfax County, sitting minutes from the Dulles Toll Road tech corridor and the Herndon Metro station on the Silver Line. Its housing stock ranges from established single-family homes near downtown Herndon and the W&OD Trail to newer townhomes and condos built up around the Silver Line corridor. As part of Fairfax County, Herndon homeowners get the same 100% solar property tax exemption under Virginia Code § 58.1-3661, Dominion Energy’s 1:1 net metering tariff, and the Virginia Solar Freedom Act’s HOA protections as the rest of the county — with the same Virginia SREC market stacking on top. The residential federal tax credit (Section 25D) expired December 31, 2025, so Herndon quotes are built on the state and local incentives that remain. We size every Herndon quote around the specific roof pitch and orientation of a home, not a generic county-wide estimate.

Herndon Solar FAQs
How much do solar panels cost in Herndon, VA?
A typical Herndon home needs an 8–12 kW system, generally $23,000–$34,000 before incentives — offset by the Fairfax County property tax exemption and Virginia SREC income. The residential federal credit ended December 31, 2025 and is quoted at $0.
Does Dominion Energy offer net metering in Herndon?
Yes — Dominion Energy Virginia credits excess solar production at the full retail rate under its 1:1 net metering tariff, which applies throughout the Town of Herndon and all of Fairfax County.
Can newer townhomes near the Herndon Silver Line station go solar?
Often, yes — newer townhome and condo roofs near the transit corridor tend to have less obstruction from mature trees than Herndon’s older established neighborhoods, though shared-roof HOA rules sometimes apply. We confirm feasibility as part of every quote.
