Estimates assume 1,560 kWh/kW/year (Sacramento valley average), PG&E E-TOU-C rates rising 4% a year, 400 W panels at 17.5 sq ft each and the 30% federal tax credit. Your proposal will use your actual shading and usage.
Three things matter most
Orientation
South-facing roofs produce the most. East and west lose about 12% but match evening peak rates better.
Time-of-use rates
Electricity from 4–9pm costs up to 3× more. A battery shifts your noon sunshine into those hours.
Future loads
Planning an EV or heat pump? Size up now — adding panels later costs roughly 40% more per watt.
