How much does solar cost and save in California in 2026?
A typical 7 kW system (18 × 400 W panels) costs about $21,000 installed and produces roughly 12,152 kWh/year at 5.8 peak sun hours. At 33.25¢/kWh with low export credit (battery usually needed), that is worth about $2,424 in the first year — a ~8.7-year simple payback with no federal tax credit.
| Item | Estimate |
|---|---|
| Installed cost at $3.00/W | $21,000 |
| Federal tax credit (§25D ended 12/31/2025) | $0 |
| Annual production | 12,152 kWh |
| Value of production counted (60% — net-metering adjusted) | $2,424/yr |
| Simple payback | ~8.7 years |
| 25-year net savings (3%/yr rate rise, 0.5%/yr degradation) | $61,600 |

Does California have net metering?
Low export credit (battery usually needed). California's Net Billing Tariff (NEM 3.0, since April 2023) credits exports at a fraction of retail, so solar-only systems save far less than before and batteries improve returns.
When exports earn little, size the system to your daytime usage, shift flexible loads (EV charging, laundry, pool pumps, water heating) into sunny hours, or pair solar with a battery. A system sized to 100% of annual use usually pays back more slowly here.
What solar incentives are available in California?
Federal: no credit for 2026 installs
The 30% Residential Clean Energy Credit (§25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Systems finished in 2025 are claimed on the 2025 return, and unused credit from earlier years can still carry forward. Leases and PPAs are the exception: the company that owns the system can still use the commercial §48E credit for systems placed in service by the end of 2027 and may pass some of that value to you.

California state and local programs
California has no state solar tax credit. The SGIP program offers battery-storage rebates (with larger incentives for income-qualified and high-fire-risk households), and solar adds no property-tax reassessment.
Program details change often — verify on DSIRE and with your utility. Policy checked September 29, 2026.
Is solar worth it in California in 2026?
Yes, for most homeowners with a sunny roof: a ~8.7-year payback is well inside a 25–30 year panel life, even without the federal credit.
