Get answers to common questions about home solar services in Annandale, Virginia.
For a typical 6-8 kW system in Annandale, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, you can reduce this by 30% with the federal Investment Tax Credit (ITC). Additionally, Virginia offers a state tax exemption on the increased home value from solar, and you may benefit from net metering with Dominion Energy, which credits you for excess power sent to the grid.
Annandale's four-season climate provides excellent solar potential, with peak production during long, sunny summer days. While winter production is lower due to shorter days and potential snow cover, modern panels are efficient in cold, clear weather. Importantly, our region receives sufficient annual sunlight (about 205 sunny days) to make solar highly viable, with systems designed to generate power year-round.
Installation requires permits from Fairfax County, which includes Annandale, for building and electrical work. Your chosen installer should handle this process, ensuring compliance with the Virginia Uniform Statewide Building Code and local zoning. A key local step is interconnection approval from Dominion Energy, which is streamlined under Virginia's net metering rules for systems under 15 kW.
Prioritize Virginia-licensed, insured, and certified installers (like NABCEP) with extensive local experience in Fairfax County. Review their portfolio of Annandale-area projects and check reviews on platforms like SolarReviews. Obtain multiple detailed quotes and confirm they handle all local permitting, interconnection, and provide strong warranties (25+ years on panels).
An ideal Annandale roof faces south, east, or west with minimal shading from mature trees (common in our area) and is in good structural condition. Reputable local installers will conduct a detailed site assessment using tools like a solar pathfinder to analyze shading throughout the year. Even partially shaded roofs can be effective with modern microinverters or power optimizers.
