Net metering, tax credits and incentives in 2026
California pays less than retail for exported solar power. Under Net Billing Tariff ("NEM 3.0"), power you send to the grid earns about 7.0¢/kWh, against 33.3¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 17.5¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
Exports earn hourly avoided-cost values (roughly 5-8¢ on average, higher on summer evenings) plus a small adder that drops to 0.9¢ for 2026 PG&E interconnections. Most new California systems add a battery to shift exports into the evening. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
California and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for California and ask installers which programs they apply for you.
