California homeowners in 2026 can access the 30% federal Investment Tax Credit (ITC), 25% CA tax credit (up to $1,000) + sales tax exemption; NEM3 billing. Stacking these incentives typically reduces a $22,000 system cost to $12,000–$16,000 net. The ITC is scheduled to step down after 2032 — installing in 2026 captures the full 30%.
All California Solar Incentives Available in 2026
The incentive landscape for California solar in 2026 is strong. Here is a complete breakdown of every program available to homeowners:
Federal Investment Tax Credit (ITC) — 30%
The federal ITC allows you to deduct 30% of your total solar installation cost from your federal income taxes. On a $22,000 system, that's a $6,600 tax credit claimed on Form 5695 when you file. The ITC applies to panels, inverters, batteries installed simultaneously, and installation labor.
California State Incentives
25% CA tax credit (up to $1,000) + sales tax exemption; NEM3 billing. California's 25% state tax credit (up to $1,000) stacks with the federal ITC. The state also exempts solar equipment from sales tax and provides the Self-Generation Incentive Program (SGIP) for battery storage.
Net Metering in California
NEM3 — export credited at avoided-cost rates by IOU. Net metering improves your system's effective yield by ensuring every kWh your panels produce has value — either consumed directly or credited against future bills.
How to Stack California Solar Incentives for Maximum Savings
- Claim the federal ITC first. Ensure you have sufficient federal tax liability to use the full 30% credit. If not, the credit carries forward to future years.
- Apply state incentives. File for the state tax credit separately on your California state return.
- Enroll in net metering immediately. Contact PG&E / SCE / SDG&E to enroll in net metering before your system turns on. Delays can cost you months of credits.
- Consider battery storage. Battery systems may qualify for the federal ITC if installed alongside solar, and some California utilities offer additional incentives for battery backup.
- Get multiple quotes. Installer pricing varies 15–30% in California. A marketplace like EnergySage lets you compare certified quotes without sharing your info with every installer individually.
How to Claim California Solar Incentives in 2026
Step 1: Install with a Certified California Installer
Only systems installed by licensed California contractors qualify for state incentives. Verify your installer's license with the state contractor licensing board before signing.
Step 2: Claim the Federal ITC
Complete IRS Form 5695 when filing your federal return. Your solar installer should provide a detailed cost breakdown documenting eligible expenses.
Step 3: File State Credits and Exemptions
File for the California state tax credit on your state return. Your installer will provide the documentation needed.

Yes. California homeowners can stack the federal ITC, 25% CA tax credit (up to $1,000) + sales tax exemption; NEM3 billing, and net metering credits from PG&E / SCE / SDG&E — all together, significantly lowering your net cost and improving your return on investment.
Do I need to own my home to claim California solar incentives?
