California Solar in 2026: Wildfires & PG&E Rates

The Perfect Storm: Wildfires and Rising Electricity Costs

California homeowners are navigating two simultaneous crises that reinforce each other: increasingly destructive wildfires and electricity rates that have more than doubled over the past decade. These aren't separate problems — they are deeply, financially entangled. And for many families, residential solar paired with battery storage has moved from a green lifestyle choice to a straightforward economic and safety decision.

Average residential electricity rates in California rose approximately 104% between January 2015 and April 2025, according to the Public Advocates Office of the California Public Utilities Commission. The average combined gas and electric bill climbed from roughly $179 per month in 2020 to around $300 today. That's not inflation. That's a structural shift in how California pays for its increasingly dangerous energy grid.

Wildfires sit at the center of that shift. Utility equipment has caused less than 10% of California's fires by count but nearly half of the state's most destructive fires on record. The financial liability from those events cascades directly onto ratepayers through billions in mandated wildfire mitigation spending — spending that shows up in your monthly bill whether you asked for it or not.

Residential solar doesn't make wildfires stop. But it does give homeowners a meaningful measure of control over their energy costs and resilience during outages — which is increasingly the point.

PG&E's Role: From Liability to Rate Increases

No utility's name is more synonymous with California's wildfire crisis than Pacific Gas & Electric. PG&E emerged from bankruptcy in 2020 after its equipment was found responsible for several catastrophic and deadly fires, including the 2018 Camp Fire in Paradise — the deadliest wildfire in California history. Since then, the company has undertaken one of the most aggressive grid hardening programs in U.S. utility history — and its customers are footing the bill.

PG&E's electricity rates have increased by approximately 41% in the last three years alone, and by more than 100% over the past decade. The primary driver isn't generation costs — it's the delivery side of your bill, the transmission and distribution infrastructure that PG&E controls and is now massively rebuilding.

The company has buried 800 miles of power lines underground since 2021, with each mile costing between $3 and $4 million. PG&E's plan to bury an additional 10,000 miles of lines in its highest-risk service territory is deeply contentious precisely because of that cost — and ratepayers bear most of it. The CPUC authorized PG&E to spend $4.66 billion on wildfire costs between 2020 and 2022. The company ultimately spent $11.7 billion and is seeking reimbursement through future utility bills.

The cycle is self-reinforcing: fires cause liability, liability triggers infrastructure investment, infrastructure investment triggers rate increases, and rate increases make energy independence via solar more financially compelling than ever.

In 2026, PG&E is implementing a new Base Services Charge in March that restructures how delivery costs appear on bills. While PG&E projects some rate stability through 2026 as certain cost recovery mechanisms roll off, its 2027–2030 General Rate Case — currently pending CPUC approval — would add additional increases in the years ahead. Experts broadly expect California electricity rates to remain elevated long-term as the state modernizes and fire-hardens its grid infrastructure.

For homeowners in PG&E territory — which spans Northern and Central California — solar is no longer just a way to reduce a bill. It is an economic hedge against a utility that has little structural incentive to lower costs and every regulatory incentive to spend more.

How Solar Became a Survival Strategy

The link between wildfires and residential solar adoption in California is both symbolic and literal. PSPS events — Public Safety Power Shutoffs — are the most direct manifestation of this link. When fire risk is high, PG&E and other utilities intentionally cut power to hundreds of thousands of homes to prevent their lines from sparking new fires. These shutoffs can last days. Homeowners with solar panels but no battery storage lose power just like everyone else. Homeowners with solar and a battery storage system can stay online independently.

This reality has transformed how Californians think about rooftop solar. It is no longer primarily a financial tool for reducing electricity bills (though it remains that). It is increasingly viewed as resilience infrastructure — a home energy system that keeps the lights on when the grid goes down, whether due to a PSPS event, a fire-related outage, or a broader grid emergency.

This shift is reflected in California's policy architecture. The CPUC's Self Generation Incentive Program (SGIP) specifically provides enhanced rebates — called "Equity Resiliency" incentives — for households in high fire-risk areas, because regulators recognize that battery storage in those communities serves a public safety function beyond individual benefit.

For homeowners in fire-prone zones across PG&E's Northern California territory, from the Sierra Nevada foothills to the Wine Country, the calculus is particularly compelling: solar-plus-storage means energy independence during the exact moments when your utility is most likely to leave you without power.

NEM 3.0: The Rule Change That Changed Everything

Before understanding the current state of California solar, you need to understand Net Energy Metering 3.0 — the policy that reshaped the market's economics more than any other development of the past several years.

Under the old NEM 2.0 framework, California homeowners who installed solar panels were credited for excess electricity they exported to the grid at close to the full retail electricity rate — roughly $0.30 to $0.35 per kilowatt-hour. That made solar a relatively straightforward investment with payback periods as short as 4 to 5 years.

In April 2023, the California Public Utilities Commission implemented NEM 3.0 (officially called the Net Billing Tariff) for all new solar interconnections. Under NEM 3.0, export compensation dropped to roughly $0.08 per kWh on average — a reduction of approximately 75% from NEM 2.0 rates. The credit a homeowner receives for sending solar energy back to the grid is now based on the wholesale "avoided cost" of electricity rather than the retail rate they pay to consume it.

This change fundamentally altered the economics of solar-only systems. Payback periods for solar without storage stretched to 8 to 10 years under NEM 3.0, compared to 4 to 5 years under NEM 2.0. The logic behind the policy shift was to incentivize battery storage — to have homeowners store their solar production and use it during evening peak hours rather than export cheap daytime energy to the grid and draw expensive evening energy back.

The strategy worked, at least in its intent. Battery attachment rates in California climbed dramatically as NEM 3.0 took effect. Solar without storage, in many cases, no longer pencils out the way it once did. Solar paired with a properly sized battery system, however, still makes strong financial sense — particularly when stacked with available California incentives and against a backdrop of rates that have doubled in a decade.

If your system was interconnected before April 14, 2023, you are grandfathered under NEM 2.0 for 20 years from your Permission to Operate date. That grandfathered status is genuinely valuable and worth preserving.

The Federal Tax Credit Is Gone — Now What?

This is the most significant policy change affecting California solar buyers in 2026, and it cannot be understated.

On July 4, 2025, President Trump signed the "One Big Beautiful Bill" (OBBB) into law. The legislation eliminated the Section 25D Residential Clean Energy Credit — the 30% federal solar investment tax credit that homeowners had relied on for two decades. Systems installed after December 31, 2025 no longer qualify for this credit. There is no phase-down, no grace period, and no grandfather clause for systems that were in progress but not yet installed by year-end.

The Solar Energy Industries Association (SEIA) described the law as making "steep cuts to solar energy" that will "slow the deployment of residential and utility-scale solar." The demand surge that preceded the December 31 deadline was historic — EnergySage reported one of the largest demand spikes the U.S. solar industry had ever seen, with most installers reaching annual capacity by October 2025.

For homeowners in California considering solar in 2026, the math has changed meaningfully. On a typical 6 kW system costing around $18,000 before incentives, the 30% ITC would have been worth approximately $5,400 in federal tax savings. That money is gone for purchased (cash or loan) residential systems.

There is one narrow federal pathway remaining: the Section 48E business investment tax credit still applies to third-party-owned solar products — residential leases and power purchase agreements (PPAs) — through the end of 2027. Under a solar lease or PPA, a third-party company owns the solar equipment installed on your roof and sells you the electricity it produces at a contracted rate. The federal tax credit flows to the system owner (the solar company), which can pass some of those savings through to you via lower rates. It is a different financial product with different trade-offs, but it remains a viable option for homeowners who want lower electricity bills without the upfront capital commitment.

The bottom line for 2026: the era of the federal residential solar tax credit is over for homeowners who purchase their systems outright. State-level programs and incentive stacking are now doing the heavy lifting.

California Incentives Still on the Table in 2026

The loss of the federal ITC doesn't mean California solar economics have collapsed. The state has a robust set of programs that, when properly stacked, can still make solar and battery storage a financially sound investment.

Self Generation Incentive Program (SGIP) The SGIP remains California's most valuable solar-adjacent incentive in 2026. Administered by the CPUC and available to customers of PG&E, SCE, SDG&E, and SoCalGas, SGIP provides rebates for battery storage systems. Standard residential rebates are approximately $150 per kWh of storage capacity. For qualifying low-income households in disadvantaged communities (the "Equity" tier) and for low-income households in high fire-risk areas or those who have experienced multiple PSPS events ("Equity Resiliency"), rebates jump substantially — to roughly $1.10 per Wh (or $1,100 per kWh) for batteries, plus $3.10 per watt for paired solar systems. SGIP Equity Resiliency is California's most powerful solar incentive in 2026 for those who qualify, but most territories face waitlists. Securing a reservation early is essential.

DAC-SASH Program The Disadvantaged Communities — Single-family Affordable Solar Homes (DAC-SASH) program offers $3 per watt for solar installations up to 5 kilowatts for income-qualifying homeowners in designated disadvantaged communities. This can cover a substantial portion of a system's cost and is stackable with SGIP.

Property Tax Exclusion California's Active Solar Energy System Exclusion prevents solar installations from triggering a property tax reassessment. Given that solar adds an estimated 6.9% to home values in California — on a $700,000 median home, that's roughly $48,000 in added value — this exclusion is worth keeping in mind.

Local and Utility Programs Municipal utilities like LADWP and SMUD offer more favorable net metering terms than the big three investor-owned utilities. LADWP customers, for example, can still access full retail-rate net metering. Community Choice Aggregations (CCAs) across the state offer additional bill credits and programs layered on top of utility-provided incentives.

Incentive stacking — combining SGIP, DAC-SASH where eligible, local utility programs, and favorable financing — can still deliver $15,000 to $43,000 in total savings depending on household income, location, and system configuration.

Solar + Battery Storage: The New California Equation

If there is a single defining trend in California's residential solar market in 2026, it is this: solar without battery storage has become significantly less attractive, and solar with battery storage has become a more complete answer to California's dual challenge of wildfire resilience and rising electricity costs.

The logic is straightforward under NEM 3.0. If you export solar energy to the grid during the day, you earn roughly $0.08 per kWh. If you pull that same energy back from the grid during evening peak hours (4 to 9 PM), you pay $0.30 to $0.55 per kWh. The spread between what you get and what you pay is enormous. A battery eliminates that spread by storing your midday solar production and discharging it during expensive evening hours, keeping that electricity in your home at full retail value.

The CPUC's own analysis shows that solar-plus-storage systems can achieve payback periods under nine years with optimized usage, saving homeowners an estimated $136 per month or more — compared to roughly $100 per month for solar-only configurations under NEM 3.0.

And then there's the resilience factor. A battery-backed solar system keeps your home powered during PSPS events and fire-related outages — the precise scenarios that are increasingly common across PG&E's service territory. For many Northern California homeowners, that's not a bonus feature. It's the primary value proposition.

Battery options in 2026 include the Tesla Powerwall 3, Enphase IQ battery systems, and Franklin WH units. A typical solar-plus-storage installation — say, a 6 kW system paired with a 13 kWh battery — runs approximately $38,000 before incentives. SGIP standard rebates can reduce that meaningfully, and for Equity Resiliency-qualifying households, the economics become dramatically more favorable.

Is Solar Still Worth It in California in 2026?

Yes — but the calculus is different than it was two years ago, and the right answer depends heavily on your specific situation.

The core economic case for solar in California remains strong because the underlying problem hasn't changed: California has among the highest electricity rates in the United States, rates driven largely by wildfire mitigation spending that will continue for the foreseeable future. PG&E's rates have doubled over the past decade. There is no credible forecast in which that trajectory reverses dramatically.

What has changed is the financial structure of the investment. The 30% federal tax credit is gone for purchased systems. NEM 3.0 has reduced the value of grid exports by 75%. Battery storage is now essentially required to maximize the economics, adding upfront cost.

For homeowners considering going solar in 2026, the strongest cases look like this:

Strong case for solar + battery: You're in PG&E or SCE territory, paying $250 to $400+ per month in electricity bills, you qualify for SGIP rebates, and you live in or near a high fire-risk area. The combination of bill reduction, wildfire resilience, and SGIP support makes the investment compelling even without the federal tax credit.

Moderate case: You're a typical homeowner with a $150 to $250 monthly bill, you don't qualify for enhanced SGIP, and you're buying a system outright. The economics are workable but the payback period is longer than it was in 2023 or 2024. A solar lease or PPA may make more sense since the 48E credit still flows to third-party owners through 2027.

Consider a lease or PPA if: You want to reduce your electricity bill immediately without a large capital outlay, and you're comfortable with a long-term contract with a solar provider. The trade-off is that you don't own the system and can't claim any credits yourself — but you benefit from lower contracted electricity rates.

The 25-year financial case remains compelling across most scenarios. Properly designed California solar-plus-storage systems still project lifetime savings of $80,000 to $120,000 depending on system size, usage, and rate trajectory.

FAQ

Is the 30% federal solar tax credit still available in California in 2026? No. The One Big Beautiful Bill, signed into law on July 4, 2025, eliminated the Section 25D residential solar tax credit for systems installed after December 31, 2025. If you installed your system in 2025 and it was fully operational by December 31, you can still claim the credit on your taxes. For new installations in 2026, the federal ITC is no longer available for purchased systems.

Can I still get a federal incentive if I lease solar panels? Yes. The Section 48E commercial investment tax credit still applies to third-party-owned residential solar systems (leases and PPAs) through the end of 2027. The credit goes to the solar company that owns the system, but they can pass savings through to you via reduced electricity rates in your agreement.

How does NEM 3.0 affect my solar savings? Under NEM 3.0 (Net Billing), you receive approximately $0.08 per kWh for excess solar you export to the grid — roughly 75% less than under the old NEM 2.0 rules. This significantly reduces savings for solar-only systems and makes battery storage essential for maximizing your return on investment.

What is SGIP and do I qualify? The Self Generation Incentive Program (SGIP) provides rebates for home battery storage systems for customers of PG&E, SCE, SDG&E, and SoCalGas. Standard rebates are roughly $150/kWh. Enhanced rebates are available for low-income households and for those in high fire-risk areas or PSPS-affected zones. Check with the CPUC's SGIP portal or a certified installer to confirm current availability and waitlist status in your territory.

Why are PG&E rates so high? PG&E's rates have been driven primarily by billions in wildfire mitigation spending — undergrounding power lines, vegetation management, equipment upgrades — mandated following its liability for several catastrophic fires including the 2018 Camp Fire. That spending is passed through to ratepayers via delivery charges. PG&E's rates rose over 101% in the past decade, with the largest increases concentrated in transmission and distribution costs that the company controls.

Will California solar rates (NEM 3.0) change? The CPUC reviews net metering policy periodically. As of early 2026, NEM 3.0 remains in effect for new interconnections. NEM 2.0 customers grandfathered before April 14, 2023 retain their rate structure for 20 years from their Permission to Operate date. Changes to NEM 3.0 are possible in future CPUC proceedings, but no significant revision is currently scheduled.
