California Solar Incentives & Rebates (2026)
California offers a $1,440 average annual net metering credit reduction under NEM 3.0, but maintains strong incentives including the $10,000+ SGIP battery rebate.
California’s solar landscape has transformed dramatically with the introduction of Net Energy Metering 3.0 (NEM 3.0) in January 2023. The export compensation rate has fallen from 100% retail to approximately 60-75% depending on your utility, significantly impacting net metering economics. However, the state compensates with robust storage incentives, property tax protections, and aggressive utility rebates.
Federal Solar Investment Tax Credit (30% ITC)
The federal solar investment tax credit covers 30% of total installation costs for systems installed through December 31, 2032. For a typical $30,000 residential system, this represents a $9,000 tax credit. Unlike rebates or deductions, the ITC applies directly to your federal income tax liability. The credit is non-refundable but can be carried forward to subsequent tax years if it exceeds your current-year tax liability.
To claim the ITC, file Form 5695 with your federal tax return in the year your system achieves operational status. Systems installed in 2026 can claim the full 30% credit. The credit applies to equipment costs (panels, inverters, mounting hardware, batteries) and labor expenses related to installation. However, it excludes financing fees, property tax exemptions, and sales tax savings.
California State-Specific Solar Programs
California’s Net Energy Metering 3.0 (NEM 3.0)
Residential customers export energy at roughly $0.10-$0.15/kWh rather than full retail rates (typically $0.25-$0.35/kWh). Commercial and larger residential systems face even steeper reductions. Importantly, NEM 3.0 includes a monthly true-up billing cycle rather than annual, affecting cash flow patterns.
Self-Generation Incentive Program (SGIP) Battery Rebate
California offers $1,500-$2,500/kWh for battery systems when paired with solar. A typical 10 kWh battery system receives $15,000-$25,000 in rebates. The program prioritizes disadvantaged communities and resilience zones. Applications are available through your local utility or approved contractors.
Property Tax Exemption
Solar installations add no assessed value to your home. A $25,000 system installation generates zero additional property tax liability in perpetuity. This exemption applies to residential, commercial, and agricultural solar systems throughout California.
No State Income Tax Credit
California eliminated its state solar income tax credit in 2006. Residents rely entirely on the federal 30% ITC and utility-specific incentives.
Utility-Level Incentives
Southern California Edison (SCE) offers time-of-use (TOU) rate shifts reducing peak period costs by 15-25%. Pacific Gas & Electric (PG&E) provides rebates for heat pump integration with solar ($500-$1,500). San Diego Gas & Electric (SDG&E) offers limited rebates due to high rooftop saturation.
Utility-Specific Rebate Programs in California
Southern California Edison (SCE) Solar Rewards Program
$0.10-$0.15/kWh during peak hours, plus equipment rebates up to $500 for qualifying storage systems
Pacific Gas & Electric (PG&E) Cool Roof + Solar Program
Combined incentives up to $2,000 when pairing solar with reflective roofing
San Diego Gas & Electric (SDG&E) Distributed Energy Resources (DER) Program
Limited availability; approximately 25 MW remaining allocation as of 2026

Frequently Asked Questions About California Solar Incentives
What’s the real financial difference between NEM 2.0 and NEM 3.0?
Under NEM 2.0, exported solar energy was credited at full retail rates year-round. NEM 3.0 credits exports at avoided cost rates (typically $0.10-$0.15/kWh), roughly 50-75% less. A system previously generating $800/year in export credits now generates $300-$400. This dramatically extends payback periods from 7-8 years to 10-12 years for many California homes.
Is the SGIP battery rebate still available in 2026?
Yes, the Self-Generation Incentive Program continues accepting applications. The rebate stands at $1,500-$2,500/kWh for new installations. However, funding reallocations have prioritized disadvantaged communities, so standard residential systems may face longer processing timelines.
Do solar panel costs get added to my property taxes?
No. California’s Proposition 13 exclusion protects solar installations from property tax assessment. This exemption has saved California homeowners over $8 billion since 2006 and applies regardless of system size.
Should I wait for NEM 4.0 instead of installing solar now?
The California Public Utilities Commission has indicated NEM 3.0 will remain in effect through at least 2029. System payback periods are still 10-12 years when factoring the 30% federal tax credit and storage incentives. Delaying installation means losing cumulative tax credits and incentive payments.
Start Your California Solar Journey
Solar incentives are substantial in 2026, but they evolve regularly. State programs are adjusted annually based on funding availability and policy priorities. Federal tax credits decrease by 2 percentage points annually after 2032, making 2026-2032 the optimal window for installations.
