What changes in Virginia
Virginia's residential electricity rate is 4.2% below the U.S. average. Combined with a planning yield of 1,422 kWh/kW-year and a $3/W installed-cost benchmark, the same 8 kW system produces a different state-level cost and value profile.
This 8 kW snapshot is a comparison scenario, not a quote. It uses CalcuRiver's state planning yield, installed-cost benchmark and EIA 2026-07 residential rate. Actual roof production, export compensation, taxes, financing and local incentives can materially change the result.

How this Virginia estimate works
- Annual production = system size × 1,422 kWh/kW planning benchmark.
- Retail-value ceiling = annual production × current Virginia residential electricity price.
- The value-capture control lets you haircut that ceiling for self-consumption/export economics.
- Simple payback = entered net installed cost ÷ modeled annual electricity value.

How Virginia differs
Virginia's July 2026 residential electricity benchmark is 4.2% below the U.S. average. Production and cost are planning benchmarks; utility export rules can change realized savings.

Why this solar estimate changes
Solar value is driven by local production, installed cost, the retail value of electricity you avoid buying, and the compensation you receive for exported energy. CalcuRiver does not assume export credits equal the retail rate unless that utility program is explicitly verified.
Core logic: self-used solar offsets retail purchases; exported solar is valued only under a verified export-compensation rule.
