The One Big Beautiful Bill Act was signed into law on July 4, 2025. For the residential solar industry, the most significant provision was straightforward: the 30% federal solar tax credit for homeowner-purchased systems, known as the Section 25D Residential Clean Energy Credit, terminated on December 31, 2025. Systems installed on or after January 1, 2026, do not qualify. There is no partial credit, no phase-down, and no transition period.
That is the bad news, and it is real. For a homeowner purchasing a $22,000 system, the expired credit represented roughly $6,600 in federal tax savings. But the end of that one incentive does not mean solar stopped making financial sense in California, and it does not mean all federal incentives are gone. The situation is more nuanced than most of what is circulating online, and Central Valley homeowners deserve a clear-eyed account of what actually changed.
What the One Big Beautiful Bill Act Actually Did to Solar Incentives
The bill made several changes to clean energy tax policy. For residential homeowners, the relevant change is singular: Section 25D, the credit that allowed individual homeowners to deduct 30% of a solar or battery installation from their federal taxes, was terminated as of December 31, 2025. The Solar Energy Industries Association (SEIA) confirmed the termination in its official analysis of the bill.
What the bill did not eliminate is the commercial investment tax credit under Section 48E. This credit is claimed by businesses, not individual homeowners, and it remains available for solar projects that began construction by July 4, 2026. The practical significance for homeowners: solar leases and power purchase agreements (PPAs) are structured as third-party-owned systems. The company that owns the panels, not the homeowner, claims the commercial credit. That company then passes the value of the credit to the customer through lower monthly payments or a reduced prepaid cost. As Solar.com explains in its 2026 California guide, third-party-owned solar arrangements are currently the only way for homeowners to indirectly benefit from a federal solar tax credit.
The table below summarizes the key provisions and their status as of mid-2026.
| Provision | What Changed | Effective Date |
|---|---|---|
| Section 25D — Residential ITC | Terminated. No federal credit for homeowner-purchased solar or battery systems. | January 1, 2026 |
| Section 48E — Commercial ITC | Still active. Third-party owners (lease/PPA providers) can still claim 30% through end of 2027 for projects beginning construction by July 4, 2026. | Phased — July 4, 2026 construction start deadline |
| Property Tax Exclusion (CA SB 710) | Not affected by the federal bill. California state exclusion remains in place with its own sunset of January 1, 2027 (PTO deadline). | CA state law — independent of OBBA |
| NEM 3.0 / Net Billing Tariff | Not affected by the federal bill. PG&E export credit structure unchanged. | No change |

Does Solar Still Make Financial Sense in California Without the Tax Credit?
Yes, for most homeowners paying above-average electricity rates, and PG&E customers in the Central Valley are firmly in that category. The tax credit changed the upfront cost calculation; it did not change the underlying math on what solar production is worth each month.
Consider the impact in practical terms. Before the credit expired, a homeowner purchasing a $22,000 system received a $6,600 federal tax credit, bringing the net cost to approximately $15,400. With the credit gone, the same system costs the full $22,000. Annual electricity savings on a PG&E bill in Fresno averaging $280 per month run approximately $2,000 to $2,600 depending on system size and usage. Analysis from EcoFlow’s solar ROI calculator estimates that payback periods in California extend by roughly two years without the credit, moving from approximately four years to six years for a Fresno-area homeowner paying a typical PG&E bill.
Six years is still a strong payback on a system that produces electricity for 25 years. After payback, the electricity the panels generate is free, and every future PG&E rate increase makes that free electricity worth more. The removal of the federal credit did not eliminate the financial case for solar in a high-rate market like the Central Valley. It extended the timeline to break even.
The Lease and PPA Option: How to Still Access a Tax Credit in 2026
For homeowners who want to reduce their upfront cost or who would rather not take on ownership of a solar system, third-party-owned options currently offer an indirect path to the commercial tax credit.
Under a solar lease or PPA, the solar company owns the equipment. The homeowner pays a monthly fee (lease) or a per-kilowatt-hour rate (PPA) that is set below the local utility rate. Because the company owns the system, it claims the Section 48E commercial credit and structures its pricing to reflect that benefit. The result, as described by NuWatt’s 2026 state-by-state solar guide, is that monthly payments under a lease or PPA are typically 10 to 30 percent below the homeowner’s current electric bill from day one, with no upfront cost.
There are trade-offs. A leased or PPA system does not add the same resale value to the home as an owned system. The homeowner does not build equity in the equipment. And when selling the home, the lease or PPA contract must be transferred to the buyer, which can add complexity to the transaction. For homeowners who plan to stay in their home long-term and want maximum lifetime savings, purchasing remains the stronger financial choice over 25 years, even without the tax credit. For homeowners who prioritize lower monthly costs from day one with no upfront commitment, a lease or PPA is worth evaluating.
What Did Not Change: California Incentives That Are Still in Place
The One Big Beautiful Bill Act is a federal law. It did not touch California’s state-level solar incentives, and those remain worth understanding before any homeowner makes a decision.
Property Tax Exclusion
California prevents a residential solar installation from triggering a property tax reassessment, even though owned solar systems add measurable market value to a home. This benefit is governed by California state law under SB 710 and is entirely independent of the federal bill. The current exclusion has a hard sunset: systems must receive Permission to Operate (PTO) from their utility before January 1, 2027. Exspenditure’s California incentives guide notes that construction completion alone is not sufficient; PTO from PG&E can take several weeks after installation, so homeowners targeting this deadline should plan accordingly.
Net Billing Tariff (NEM 3.0)
The federal bill made no changes to California’s solar export credit structure. PG&E’s Net Billing Tariff continues to credit solar customers for excess energy exported to the grid at time-varying wholesale rates. Homeowners who pair solar with battery storage can still maximize their savings by storing midday production and using it during the 4 to 9 PM peak window, when grid electricity is most expensive.
SGIP Battery Rebates
California’s Self-Generation Incentive Program, which provided battery storage rebates for qualifying households, closed its general market funding at the end of 2025. Equity and resiliency program funding remains available for income-qualified households and those in designated high fire-threat districts. Homeowners in Fresno and the broader Central Valley should ask their installer to confirm current SGIP availability for their specific situation, as funding levels and category availability change. The CPUC administers SGIP through PG&E, SCE, and SDG&E.
Frequently Asked Questions
Is there any federal solar tax credit available for homeowners in 2026?
Not for homeowners who purchase a solar system outright. The Section 25D Residential Clean Energy Credit terminated on December 31, 2025. Homeowners who go solar through a lease or PPA can indirectly benefit from the commercial tax credit, which the third-party system owner claims and passes through as lower pricing. The SEIA has confirmed the 25D termination in its official analysis of the bill.
Can I still claim the tax credit if I installed solar in 2025?
Yes. If your system was installed and operational before December 31, 2025, you are still eligible to claim the 30% credit on your 2025 federal tax return. The termination applies to systems placed in service on or after January 1, 2026. There is no retroactive component to the law.
Did the One Big Beautiful Bill change anything about California’s net metering program?
No. The bill is federal legislation and did not affect California’s state-administered Net Billing Tariff. PG&E customers who go solar in 2026 are subject to the same NEM 3.0 export credit structure that has been in place since April 2023. The federal bill’s solar provisions were limited to tax credits under the Internal Revenue Code.
Is a solar lease a good option now that the residential credit is gone?
It depends on your priorities. A lease or PPA offers immediate monthly savings with no upfront cost, and the third-party owner passes through the value of the commercial tax credit in the form of lower pricing. The trade-off is that you do not own the system, it may not add resale value to your home the way an owned system does, and the contract must transfer to the buyer if you sell. For homeowners who want day-one bill reduction without capital outlay, it is worth a serious look. For those who want maximum long-term savings and home equity, purchasing remains the stronger 25-year play.
Does the expiration of the federal tax credit mean solar is no longer worth it?
Not for Central Valley homeowners on PG&E. The credit made the upfront cost lower and the payback period shorter; it did not create the underlying savings. Those savings come from producing electricity at a fixed cost instead of buying it from PG&E at rates that continue to rise. EnergySage data for Fresno County shows average payback periods of approximately four years before the credit expired. Post-credit estimates extend that to around six years, still an excellent return on a system that produces electricity for 25 years.
What Fresno Homeowners Should Take Away from This
The One Big Beautiful Bill Act changed one significant piece of the solar financial equation: it removed the federal tax credit for homeowners who purchase systems outright. Everything else, PG&E rates, Fresno sun hours, the property tax exclusion, NEM 3.0, and California’s long-term rate trajectory, remained in place.
For homeowners who installed before the deadline, nothing has changed and the tax credit will appear on their 2025 return. For homeowners who are evaluating solar now, the question is not whether the incentive landscape is as favorable as it was in 2024. It is not. The question is whether the remaining financial case makes sense given their specific PG&E bill, their roof, and how long they plan to stay in the home. For most Fresno-area homeowners paying $200 or more per month to PG&E, the answer is still yes.
