Estimated production
4 panels of Mission Solar MSE380SX5R in LA produce about
4 panels × 380 W = 1.52 kW of panel
kWh per month, DC at the panel before inverter conversion. Assumes nameplate STC power, a 20° south-facing open-rack mount, typical-year weather for California, and PVWatts default system losses of about 14% (soiling, shading, wiring, mismatch and availability). A real roof's tilt, orientation and shade will move these numbers.
What an array this size is worth
Priced as an installed grid-tied system against 14,400 kWh a year of household use, on the production estimated above once a typical inverter has converted it to AC. Every assumption here is a slider — change anything that doesn't match your case.
