How this calculator works
Estimates daily kWh usage based on household size, state climate, and major appliances (AC, pool, solar offset). Multiplies by your tariff rate, adds the daily supply charge, and projects to a quarterly bill. Solar offset reduces usage based on system size and state irradiance.
