Are Solar Panels Worth It in California?
Last updated July 1, 2026 · based on California energy prices
In California, where residential electricity averages about 32¢/kWh and rooftop solar yields roughly 1,550 kWh per kW per year, solar pays back relatively quickly — roughly 9.4 years at California electricity prices.
California solar cost & savings (typical 7 kW system)
| Metric | Estimate |
|---|---|
| Annual production | 10,850 kWh |
| Installed cost (before incentives) | $21,000 |
| Estimated annual savings | $2,224 |
| Payback period | 9.4 years |
| 25-year net savings | +$31,394 |
Figures use California average prices, a 7 kW system at $3.00/watt, 50% self-consumption at retail plus a conservative 9¢/kWh net-metering credit, and ~0.5%/yr panel degradation. Sources: EIA electricity prices and NREL PVWatts production modeling.
What this means for California homeowners in 2026
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in California carries the full upfront cost unless a state or utility incentive applies. Because California electricity costs well above the national average, the payback case is favorable for most well-suited roofs.

Are solar panels worth it in California in 2026?
At California's electricity price of 32¢/kWh, a typical 7 kW system saves about $2,224 per year and pays for itself in roughly 9.4 years. There is no federal solar tax credit in 2026 (Section 25D expired December 31, 2025), so these figures reflect bill savings and net metering only.
How much do solar panels cost in California?
A 7 kW system costs roughly $21,000 installed at about $3.00/watt before any state or utility incentive. Costs vary by installer, equipment, and roof complexity.
How much electricity will solar produce in California?
About 1,550 kWh per year per kW installed in California, so a 7 kW system produces roughly 10,850 kWh/year. Your exact output depends on roof orientation, tilt, and shading.
