California Solar Incentives (2026): Programs, Credits, and Utility Rules
California has some of the most impactful Solar Incentives in the U.S., but they don't all work the same way. Some savings come through your federal tax return, others through California programs like battery rebates, and many depend on your utility's solar billing rules. This guide breaks down the incentives homeowners and small businesses most often use in 2026, plus practical Solar Installation steps so you can plan with fewer surprises.
California Solar Incentives at a Glance
In 2026, California's biggest opportunities typically fall into three buckets:
- Federal tax incentives that reduce your income tax bill (and can apply to solar and batteries).
- California programs that support specific customer groups, especially energy storage and income-qualified households.
- Utility rate rules that determine how exported solar power is credited under the Solar Billing Plan (also called the Net Billing Tariff).
If you want a quick refresher before you compare quotes, SolarTech's ways incentives can lower system cost can help you sanity-check what an installer includes (and what they don't).
Federal Solar Incentives for California Homeowners and Businesses
Residential Clean Energy Credit (solar + batteries)
Most homeowners focus on the federal Residential Clean Energy Credit. The IRS explains how qualified expenses work, including the key detail that public utility subsidies/rebates are generally subtracted from qualified expenses (while net metering credits typically don't reduce qualified expenses).
Practical takeaway: if you receive a rebate (for example, for battery storage), it may reduce the amount you can use to calculate your federal credit—so your final savings depends on how incentives stack.
Business clean energy tax credits
Small businesses may qualify for separate federal clean energy credits depending on how the system is owned and placed in service. Start with IRS guidance and your tax professional for the business pathway.
California Property Tax Relief for Solar
Active Solar Energy System Exclusion (property tax exclusion)
California has a property tax exclusion for qualifying active solar energy systems. The California State Board of Equalization notes the exclusion's sunset timing and extension through the 2025–26 fiscal year, with the statute scheduled to sunset January 1, 2027.
Why it matters: solar can increase home value, but this exclusion is designed to prevent certain solar-related value increases from triggering new construction reassessment treatment during the eligible period.
Battery Rebates in California
Self-Generation Incentive Program (SGIP)
SGIP is California's flagship incentive for energy storage. It provides incentives that support distributed energy resources, including battery storage, and includes equity-focused categories in its broader program structure.
SGIP availability and rules can vary by territory and funding status, so it's smart to check your utility's SGIP page alongside CPUC program info.
Why batteries are a bigger deal in California now: under the Solar Billing Plan, export credits are time-varying and often lower than retail rates, so many households use batteries to shift usage or exports into higher-value hours.
Income-Qualified and Disadvantaged Community Solar Programs
California has multiple CPUC programs aimed at expanding access beyond "standard" rooftop solar economics.
DAC-SASH (Disadvantaged Communities – Single-family Solar Homes)
DAC-SASH enables income-qualified homeowners in disadvantaged communities to receive no-cost rooftop solar installations, per CPUC program descriptions.
DAC-GT (Disadvantaged Communities – Green Tariff)
DAC-GT is designed for income-qualified customers in disadvantaged communities who may not be able to install solar on their roof, providing utility-scale clean energy with a bill discount.
CSGT (Community Solar Green Tariff)
CSGT provides local solar energy with a bill discount structure, and it includes community sponsorship and workforce development elements as described by the CPUC.
CARE and FERA utility bill discounts (often tied to eligibility)
Many low-income clean energy programs use CARE/FERA as eligibility or enrollment touchpoints. CPUC guidance explains FERA and which major utilities it applies to.
Multifamily Affordable Housing Incentive: SOMAH
Solar on Multifamily Affordable Housing (SOMAH)
SOMAH provides financial incentives for installing solar on qualifying multifamily affordable housing. CPUC program information includes incentive level details and how projects are structured.
If you're a property owner/manager, SOMAH is often one of the most meaningful California Solar Incentives because it's designed around tenant benefits and affordable housing requirements.
Community Solar and "Solar for All" Developments
California also has broader efforts to expand community solar and solar + storage access. The California Energy Commission's Solar for All program page outlines the program's planning status and coordination across agencies.
Net Metering in California: What Replaced It and Why It Matters
Solar Billing Plan (Net Billing Tariff / "NEM 3.0")
Most new interconnected solar customers in the major investor-owned utility territories are under the Solar Billing Plan (Net Billing Tariff). SCE describes it as the successor to prior NEM tariffs for customers applying after April 14, 2023.
Under CPUC's net billing explanations, export compensation (energy export credits) is generally lower than retail rates but can rise during certain high-value hours—one reason batteries can improve savings.
Where to find export credit values
Utilities publish export pricing references and point back to CPUC-provided values and/or tariff details.
Compare Options the Smart Way
Solar Companies can present incentives very differently in proposals—some show "after incentives" pricing that assumes you qualify for every program. Before you sign, compare at least two to three offers and ask each bidder to separate (1) guaranteed utility/program rebates from (2) tax credits you claim yourself.
Solar Installation Basics in California
A typical Solar Installation flow looks like this:
- You collect site info and electric bill history so the system can be sized appropriately.
- The contractor completes a site visit and final design, then submits for permits and utility interconnection.
- Installation happens after approvals; then inspections and utility "permission to operate" follow.
- After PTO, you track billing and export credits under the Solar Billing Plan (or applicable tariff).
Because some incentives are reservation-based or funding-limited, it's important to confirm program steps early—especially for SGIP.
What is Needed for Solar Installation in California
Homeowners and small businesses usually need a mix of home readiness, paperwork, and utility steps. Here's what typically matters most:
- Roof and site suitability: roof condition, shading, and usable space (and whether you need a reroof first).
- Electrical readiness: main panel capacity, service size, and space for breakers; battery installs can add requirements.
- Permits and local requirements: building/electrical permits and inspections, plus HOA rules if applicable.
- Utility interconnection: your installer submits the interconnection application and sets expectations for the tariff you'll be on.
- Documentation to claim incentives: itemized invoices, proof of project completion/PTO, and any program eligibility documentation (especially for income-qualified programs and SGIP).
How to Evaluate Solar Companies Without Getting Misled by Incentives
When comparing Solar Companies, incentives should be presented as either guaranteed (rebates approved by a program administrator) or conditional (tax credits depend on your tax situation; some programs depend on eligibility and available funding). A clean quote will clearly show:
- Cash price and financed price (not just monthly payment)
- Battery details if included, and whether SGIP is assumed or confirmed
- Your expected tariff and how export credits are modeled under the Solar Billing Plan
- A timeline for permits, installation, inspection, and PTO
