California has more rooftop solar than any other state — and the highest electricity rates in the country, averaging about 33¢/kWh. That combination still makes solar one of the best home upgrades a California homeowner can make, but the math changed in 2026: the federal residential tax credit is gone and NEM 3.0 net billing has reshaped how exported power is paid. Here is what installing solar in California actually costs and saves in 2026.

A typical residential solar system in California runs $2.50–$2.80 per watt installed. Most homes need a 8–9 kW system, which lands at roughly $18,700–$25,300 before incentives, with a payback period of about 7–9 years. With local electricity at about ~33¢/kWh (roughly 80% above the U.S. average), every kilowatt-hour you self-generate is worth that much off your bill.
Pairing solar with a battery adds roughly $10,000–$16,000 but is now central to the economics under NEM 3.0 — storing midday production to use during the expensive evening peak is what drives the savings.

The federal residential tax credit ended on December 31, 2025, so California's state, utility, and financing-based incentives now do the heavy lifting. Here is the current stack.
Homeowners who buy a system in 2026 can no longer claim the 30% federal credit; it ended December 31, 2025. A solar lease or PPA can still pass through the commercial 48E credit via the system owner. IRS — One Big Beautiful Bill FAQ
The Self-Generation Incentive Program still pays for home batteries. General-market funds (~$200/kWh) are largely exhausted, but equity and equity-resiliency tiers run far higher — up to roughly $1,000–$1,100/kWh for qualifying low-income, medical-baseline, or wildfire/PSPS-zone households.

California excludes the added value of a solar system from your property-tax assessment — but the exclusion is set to sunset, so systems generally must be completed before January 1, 2027 to lock it in. CA Board of Equalization

Since April 2023, PG&E, SCE, and SDG&E customers fall under NEM 3.0, the Net Billing Tariff. Instead of crediting exported power at the retail rate, exports are now paid at the utility's avoided cost — frequently in the range of 4–8¢/kWh rather than the ~30¢ you pay to buy power. That ~25%-of-retail export value is exactly why a battery matters: self-consuming your own stored energy in the evening is worth far more than exporting it midday. NEM 3.0 was upheld by a California appeals court in March 2026. CPUC NEM 3.0 (coverage)
Solar installers in California must hold an active CSLB license — typically a C-46 (Solar) or C-10 (Electrical) classification. Look up any contractor's license number on the CSLB site to confirm it is active, bonded, and free of disciplinary actions. Check it at the California Contractors State License Board (CSLB).
Favor crews with at least one NABCEP-certified installer, verify $1M+ general liability plus workers' compensation, and insist on a written workmanship warranty of 10 years or more in addition to the panel and inverter manufacturer warranties.

The largest rooftop-solar market in the U.S.; LADWP and SCE territory with strong owner-occupied demand.
SDG&E has the highest rates in the state, giving solar-plus-battery the fastest payback in California.

Served by SMUD, a municipal utility outside NEM 3.0, with its own solar and battery/VPP incentives.
Hot Central Valley climate and strong irradiance drive both home and agricultural solar.
California commercial solar is having a stronger year than residential: businesses keep the 30% federal credit through Section 48E (for projects that begin construction by mid-2026), stack it with MACRS depreciation, and can add a domestic-content bonus. High commercial demand charges make solar-plus-storage attractive for peak-shaving, and NEM aggregation lets agricultural and multi-meter sites spread credits across meters.

Residential solar systems in California typically cost $16,000–$26,000 installed. California's net billing rules favor pairing solar with battery storage for best economics The federal residential ITC (Section 25D) expired December 31, 2025, so state and utility incentives are now the main driver of net cost.
California homeowners may benefit from California Solar Initiative, DAC-SASH for low-income households, and NEM 3.0 net billing through the IOUs. Solar leases and PPAs may still capture the commercial 48E credit indirectly. Ask any contractor on this page for a current incentive stack analysis specific to your address and utility.
Every state maintains a contractor licensing database — typically operated by the state's Department of Consumer Affairs, Contractors State License Board, or Board of Electrical Contractors. Ask the contractor for their license number and verify it directly. Top Solar Services confirms license status before issuing the Verified or Premier Verified badge.
For many California homeowners, yes — particularly where retail electricity rates are high, net metering exists at retail or near-retail rates, and state rebate or SREC programs apply. The federal residential 25D credit expired December 31, 2025, which has stretched typical payback periods, but lifetime savings on a 25-year system remain positive in most cases. Solar leases and PPAs (third-party owned systems) may still capture the commercial 48E credit indirectly through pricing.
