⚠️ 2026 update on the federal tax credit
The 30% federal residential solar tax credit (Section 25D) expired on December 31, 2025 for systems you buy with cash or a loan. Cost and savings figures on this page that assume that credit may be out of date. Two things still apply: Nevada's sales-tax and property-tax exemptions and NV Energy net metering, and systems on a lease or PPA may still qualify for a federal incentive through the end of 2027. For numbers that reflect today's incentives, book a free review and talk to a tax professional about your situation.
California's Self-Generation Incentive Program (SGIP) pays $150–$1,000 per kWh of installed battery storage in 2026, depending on which tier you qualify for. A 13.5 kWh Powerwall in a high-fire or low-income zone can land $5,000–$13,500 in rebate; in the standard residential tier, expect $1,000–$2,500. The catch is that the largest tiers (equity, equity resiliency) require specific income, location, or medical-baseline qualifications.
What SGIP is
SGIP is California's storage incentive, administered by the CPUC and funded through ratepayer charges. It pays a per-kWh rebate to homeowners and businesses who install qualifying battery storage. Full program docs at CPUC SGIP page.
The five tiers (residential)
- General Market (Tier 1): ~$150–$200/kWh. Open to most California homeowners. Funds run out fast — often waitlist-only.
- Equity (Tier 3): ~$850/kWh. Requires CARE/FERA enrollment, low-income housing, or San Joaquin Valley disadvantaged community status.
- Equity Resiliency (Tier 4): ~$1,000/kWh. Requires equity eligibility PLUS one of: PSPS-affected area, high fire threat district (HFTD Tier 2 or 3), or medical baseline customer.
- Small Business Equity: Different scale, not covered here.
- Heat Pump Water Heater (HPWH): Newer tier, separate eligibility.
Real example payouts
A single Tesla Powerwall 3 (13.5 kWh usable) installed in California:
- General Market: 13.5 × $150 = $2,025
- Equity: 13.5 × $850 = $11,475
- Equity Resiliency: 13.5 × $1,000 = $13,500
Two Powerwalls (27 kWh usable) at Equity Resiliency = $27,000 of rebate. On a $30,000 two-Powerwall install, that SGIP rebate alone can cover most of the cost in equity-tier scenarios. Note: the 30% federal credit expired December 31, 2025 for purchased systems, so for a 2026 cash or loan buy there's no longer a federal credit to stack on top — SGIP is now the incentive that moves the number.
Who qualifies for Equity / Equity Resiliency
This is where the real money is. Equity tier requires one of:
- Enrolled in CARE or FERA (utility low-income programs)
- Live in a deed-restricted low-income housing development
- Live in a San Joaquin Valley Disadvantaged Community
- Tribal land
Equity Resiliency adds requirements:
- Located in High Fire Threat District (HFTD) Tier 2 or Tier 3 (check at the CPUC HFTD map)
- Or medical baseline customer (electricity-dependent medical equipment)
- Or experienced 2+ PSPS events in past 3 years
NEM 3.0 and SGIP — why they go together
Under California's NEM 3.0, exporting solar to the grid pays much less than retail. Self-consuming via battery is now the central economic strategy for new California solar. SGIP exists partly to subsidize that shift. If you're in California and adding solar in 2026, you should be modeling solar + battery, not solar alone. More on California specifics in Solar in California.
Application process
- Confirm tier eligibility (your installer should help; don't assume)
- Pre-application reservation through your utility's SGIP portal (PG&E, SCE, SoCalGas, or SDG&E for incentives)
- Reservation locks in your incentive funding while permits and install proceed
- Install + interconnection
- Performance verification — most tiers require 5 years of operational compliance, including annual discharge requirements
- Rebate paid to installer (assigned) or homeowner
Funding runs out — speed matters
SGIP is budgeted in tranches. General market funds are usually exhausted within weeks of opening. Equity and Equity Resiliency typically have longer availability but still run out. Check your utility's current SGIP funding status before getting too excited about a quoted rebate. DSIRE California tracks current program status.
The federal tax credit no longer stacks
The 30% federal Residential Clean Energy Credit (IRS page) used to stack with SGIP on a purchased battery. That credit expired December 31, 2025 for systems you buy, so for a 2026 cash or loan install there's no federal credit to stack — SGIP stands on its own. Only lease and PPA systems can still capture a federal incentive (through end of 2027), and there the third-party owner claims it. If you're buying, model SGIP plus NEM 3.0 self-consumption, not a federal credit.
What to watch for
- Installer assigning your rebate to themselves. Read the assignment language. Sometimes appropriate, sometimes not.
- Inflated battery pricing on rebate jobs. Some installers raise prices to capture the rebate as margin. Compare cash quotes with and without SGIP.
- Performance verification failures. If your battery doesn't discharge per the program rules, partial rebate clawback is possible.
- Eligibility misrepresentation. If you claim equity tier without actually qualifying, the rebate claws back and the installer gets blacklisted. Verify CARE/FERA enrollment before assuming.
Why I cover SGIP from Nevada
I install across the Nevada–California border for clients with second homes and clients in Inyo, Mono, and San Bernardino counties — areas with HFTD Tier 2/3 designations and real PSPS exposure. The economics of California battery storage in 2026 now rest on two levers for owners: SGIP and NEM 3.0 self-consumption (the federal 30% credit expired December 31, 2025 for purchased systems). Done right, an equity-tier SGIP rebate can still make out-of-pocket on storage in California lower than in Nevada. Done wrong, you miss the rebate window entirely.
