Is solar worth it in California? (2026)

Solar pays off for most California homeowners over a 25-year system life — but 2026 marks a real turning point. The federal residential solar tax credit expired December 31, 2025, adding roughly $7,000–$10,000 back onto your out-of-pocket cost, and California’s NEM 3.0 export rules have already cut the value of power you send to the grid. Expect a simple payback of 7–12 years depending on your usage profile and whether you pair panels with a battery — still a solid financial return, but a harder upfront case than two years ago.

Why California’s fundamentals still work

Four variables determine whether solar makes economic sense: electricity rate, net-metering quality, sun, and local incentives.

Electricity rate: strong. California’s residential rate sits at 31.6¢/kWh — roughly double the national average. Every kilowatt-hour your panels produce and your household consumes directly is worth 31.6 cents in avoided costs. High electricity rates are the single biggest driver of solar savings, and California ranks among the top states in the country on this measure.

Net metering: weakened. The shift to NEM 3.0 — officially the Net Billing Tariff — is the most consequential policy change in California solar in a decade. Under NEM 2.0, power exported to the grid was credited at close to retail rates: roughly the same 31.6¢ you’d pay to buy it back. Under NEM 3.0, those exports earn the avoided-cost rate, averaging roughly 5–9¢/kWh depending on the hour. Midday solar that hits the grid now earns about one-fifth of what it did two years ago. That shift is why a battery has moved from a nice-to-have to the product that largely defines your payback timeline.

Sun: excellent. California averages 5.5 peak sun hours per day statewide — more in the Inland Empire, Central Valley, and Southern California; slightly less along the coast. A clear, south- or west-facing roof with no major shading will get maximum production from that resource.

Incentives: limited in 2026. There is no California state income-tax credit for solar. The federal residential credit (IRC §25D) expired December 31, 2025 and delivers $0 in tax savings for systems purchased in 2026. What remains: a California property-tax exclusion that shields the added home value from reassessment, and the SGIP rebate, which can meaningfully offset battery storage costs for eligible households. For a full breakdown, see California solar incentives.

A real numbers example

Take a home in Sacramento averaging $260/month in electric bills — approximately 9,800 kWh per year at 31.6¢. An installer sizes an 8 kW system.

Upfront cost: 8,000 W × $2.95/W = $23,600 (estimate; prices vary by roof type, panel brand, and installer — get itemized quotes from at least three companies)

Annual production: 8 kW × 5.5 hours × 365 days ≈ 16,060 kWh

Under NEM 3.0 without a battery, figure roughly 55% self-consumption — production used directly in the home during daylight hours:

• Self-consumed: 8,830 kWh × $0.316 = **$2,790 in avoided costs** (estimate)
• Exported: 7,230 kWh × $0.07 avg = **$506 in export credits** (estimate)
• Total estimated annual value: ~$3,300
• Simple payback: $23,600 ÷ $3,300 ≈ 7.2 years

Had the 30% federal credit still applied, net cost would have been roughly $16,520 — a payback of about 5 years. Losing the credit alone adds roughly two years to this example. Combined with the lower NEM 3.0 export rates compared to the pre-2023 era, many California homeowners now face a payback 3–5 years longer than projections from just a few years ago suggested.

Over 25 years, that same system could produce an estimated $60,000–$85,000 in total value against a $23,600 investment — rough estimates that depend heavily on future rate changes. Use the solar savings calculator to model your specific home and usage.

What adding a battery changes

Under NEM 3.0, a battery is no longer optional if you want to maximize your return. The logic is straightforward: store solar energy produced at midday — when export credits are low — and discharge it in the evening, when you’d otherwise buy power at 31.6¢.

A quality 10–13 kWh home battery adds roughly $10,000–$14,000 to system cost before incentives. The SGIP rebate used to offset a meaningful chunk of that, but the standard residential SGIP budget closed at the end of 2025 — only equity and high-fire-risk tiers remain, and they’re often waitlisted. Unless you qualify for one of those tiers, budget for the battery at full price and treat any SGIP rebate as a bonus, not a baseline.

With a battery pushing self-consumption to 75–85%, that same 8 kW system could generate an estimated $4,200–$4,800 per year in savings, cutting payback on the combined solar-plus-storage investment to roughly 8–10 years. That is not faster in dollar-payback terms than solar alone — the battery carries its own cost — but it adds backup power, protection against evening peak rates, and the ability to draw on stored solar during the most expensive billing hours.

Leases and PPAs follow different economics: you don’t own the system and receive no direct tax credits. The solar company may pass through savings from the commercial §48E credit (still active in 2026), often resulting in a lower monthly payment than your current utility bill. If the $23,600+ upfront cost is a barrier, a PPA is worth comparing — just read the rate escalator clause carefully before signing.

Who it makes sense for in 2026

Profile	Solar worth it?	Notes
Own your home, planning to stay 10+ years	Yes	Long ownership horizon captures most of the 25-year value
High electricity bills ($200+/month)	Yes	More kWh to offset at 31.6¢ improves the math significantly
South- or west-facing roof, minimal shade	Yes	Maximizes production from California’s 5.5 peak sun hours
Can add a battery or size for self-consumption	Yes	Mitigates the impact of low NEM 3.0 export rates
Planning to sell within 3–5 years	Wait or lease	Payback unlikely to complete; explore PPA or disclose to buyer
Heavily shaded or north-facing roof	Wait	Poor production undercuts the economics regardless of rates
Renting your home	Not applicable	Look into community solar subscription programs instead
Cash-limited, no access to solar loan	Evaluate PPA/lease	$23,600+ upfront is a real barrier; third-party options exist

The 25-year picture

Even at a 7–10 year payback, the case over the full system life is strong. Panels carry 25-year performance warranties. California electricity rates have risen an average of 4–5% annually over the past decade, with no sign of reversing — every rate increase raises the value of every kWh your panels produce. That compounding effect is what makes the long-term economics resilient even without the federal credit.

For homeowners who own their roof, plan to stay, and can size the system to their actual consumption rather than oversizing, California solar in 2026 is a financially sound decision. The payback window is longer than the 2022–2024 era led people to expect. The 25-year return is not.

Check current solar panel cost in California to benchmark any quote you receive. Ask every installer to show you a savings model built on NEM 3.0 export rates — not outdated NEM 2.0 assumptions. If a salesperson mentions a 30% federal tax credit for a 2026 purchase, treat that as a serious red flag.
