How net metering works
When panels produce more than you use, surplus energy flows to the grid. Your utility credits your account — at retail, avoided-cost, or buyback rates depending on policy.
California has the highest installed solar capacity in the US, with competitive installer markets in Los Angeles, San Diego, and the Bay Area. NEM 3.0 reduced export credit values — sizing for self-consumption is more important than oversizing for grid export.
- Daytime surplus → bill credits
- Evening usage → draw from credits
- Annual true-up may settle remaining balance
California net metering policy
California homeowners qualify for the 30% federal ITC. Check dsireusa.org for active utility rebates — programs change frequently by IOU territory.
California runs 10–20% above US average install cost but high electricity rates ($0.28+/kWh) support strong savings.
Net metering vs battery storage
If export credits are low in California, batteries store solar for evening use. Add-on cost: $10,980 before ITC.
