Planning estimate only, not a quote. Based on typical California rates, sun hours and installed prices. It does not include tax credits or incentives (the federal residential solar credit ended after 2025; business credits and state programs may still apply and we review them with you). Your real numbers come from a site assessment and your actual utility bills.

How this estimate works
- · We convert your bill to yearly usage using a typical all-in rate for your utility.
- · Solar is sized to cover about 95% of that usage, at about 1,450 kWh per kW per year.
- · Savings reflect California's net billing rules: power you use yourself is worth more than power you export, which is why a battery raises savings.
- · The 25-year figure assumes utility prices rise 3% a year and panels lose 0.5% output a year.
- · Prices are typical installed ranges before incentives. Roof condition, panel upgrades, trenching and structures change the real number.
