why this estimate changes

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.
