What Solar Incentives Are Still Available in California in 2026?
The biggest change for 2026: the Federal Residential Solar Tax Credit (ITC) expired on December 31, 2025 for homeowner-owned systems. But that doesn't mean solar is unaffordable — California homeowners can still save 30-50% through alternative financing structures and state programs. Here's your complete guide to what's available right now.
Up to 40% Discount Through PPA and Prepaid Lease with Domestic Content Bonus
While the residential ITC expired, the commercial solar ITC remains at 30% base credit under Section 48E. Third-party solar companies can claim this credit and pass the savings to you through a Power Purchase Agreement (PPA) or prepaid lease structure. Even better: if the installer uses domestically manufactured panels and components (meeting U.S. steel/iron and 45% domestic manufactured component requirements), the credit jumps to 40% with the domestic content bonus. This full 40% discount gets passed to you at the point of sale. Advanced Conservation Systems uses qualifying domestic-content equipment to ensure our customers get the maximum discount available.
How the 40% PPA/Lease Discount Works
Here's the structure: A third-party company owns the solar system, claims the 40% federal credit (30% base + 10% domestic content bonus) at the corporate level, and passes that full discount to you as a price reduction. On a $30,000 system, that's a $12,000 discount — and you don't need to have a tax liability to benefit. The system is installed on your roof, you get the energy savings, and the financing company handles the tax credit. Projects must begin construction before July 4, 2026 to qualify for the domestic content bonus.
Additional Bonus Credits That Can Stack
The 2026 commercial ITC under Section 48E is stackable with additional bonuses beyond the domestic content adder. Projects in designated energy communities (areas with significant fossil fuel employment or retired coal plants) qualify for an additional +10%. Projects serving low-income communities can qualify for +10-20% more. In total, the ITC can reach up to 70% for qualifying projects. Ask Advanced Conservation Systems if your location qualifies for any of these bonus credits.
NEM 2.0 Grandfathering Deadline: April 15, 2026
If you submitted your solar interconnection application before April 15, 2023, you have until April 15, 2026 to complete your grid connection and lock in NEM 2.0 rates. NEM 2.0 credits solar exports at near-retail rates (25-35 cents/kWh), which is significantly more valuable than NEM 3.0's 5-8 cents per kWh. If you're grandfathered under NEM 2.0, act immediately — this deadline is fast approaching.
NEM 3.0: Battery Storage Is Essential
New solar customers in 2026 are under NEM 3.0 (Net Billing Tariff), which reduced export compensation by about 75% compared to NEM 2.0. The key strategy is pairing solar with battery storage like the Tesla Powerwall to store excess energy during the day and use it during expensive evening peak hours (4-9 PM). This self-consumption approach can deliver payback periods of 6-8 years in Lancaster's sunny climate.
SGIP Battery Rebates: Equity Budget Still Available
The ratepayer-funded SGIP budgets closed December 31, 2025, and general market applications are waitlisted. However, the RSSE (Residential Solar and Storage Equity) program funded by $280 million in state money is still accepting waitlist applications, offering up to $1,100/kWh for battery storage for qualifying low-income households. Many Antelope Valley communities qualify for this equity-tier pricing.
California Property Tax Exclusion — Through 2027
Solar energy systems installed before January 1, 2027 are excluded from property tax reassessment. Your solar panels won't increase your property taxes, even though they add $15,000-$30,000 in market value to your home.
How Lancaster Homeowners Save Big in 2026
The combination of the 40% PPA/lease discount with domestic content, NEM 3.0 savings with battery storage, property tax exclusion, and potential SGIP equity rebates means solar remains one of the best investments for Antelope Valley homeowners.
