Net metering / billing
NEM 3.0 (Net Billing)

Under California's Net Billing Tariff (NEM 3.0, April 2023), exported power earns avoided-cost rates (~$0.02–0.08/kWh); self-consumed solar saves at full retail rate, so battery storage maximizes value.

Estimates use the average California current utility rate (before solar) of $0.33/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
