Solar Without the Federal Tax Credit in California

Start with the current federal rule

The IRS's current energy-credit guidance says the Residential Clean Energy Credit under Internal Revenue Code Section 25D is not allowed for expenditures made after December 31, 2025. Its transition FAQ explains that a solar expenditure is generally treated as made when the original installation is completed. If installation finished after December 31, 2025, paying or signing earlier does not preserve the homeowner credit.

That rule changes the arithmetic for a new 2026 homeowner-owned project. A proposal should not reduce the displayed net price by 30%, describe the expired credit as money back, or imply that a homeowner can claim it later. Tax situations can be complex, so use the current IRS material and a qualified tax professional for individual advice. A salesperson's worksheet is not a tax determination.

Rebuild the ownership comparison from the full price

For a cash purchase, begin with the complete contract price before any uncertain incentive. Identify the modules, inverter, battery, electrical work, roof work, permits, interconnection support and monitoring included. List exclusions separately. A lower headline price may omit a main-panel upgrade, reroofing, trenching, backup equipment or work required by the authority having jurisdiction.

For a loan, compare the same installed scope and show the principal, interest rate, term, payment schedule, fees and total of payments. Ask whether the quoted payment assumes a voluntary principal reduction that was previously expected from a tax refund. If it does, request a second schedule with no such reduction. The useful comparison is the amount the household is obligated to pay, not a net figure that depends on a credit unavailable to a new 2026 installation.

Understand why third-party ownership is different

A lease or power purchase agreement is not a homeowner purchase of the solar equipment. Under a lease, the customer generally pays for use of the system; under a PPA, the customer generally pays for the electricity it produces. The provider owns the equipment during the agreement term, subject to the controlling contract. That ownership difference can change who may use business-related tax attributes, but it does not create a Section 25D homeowner credit for the customer.

Compare the actual agreement rather than treating third-party ownership as a replacement tax credit. Record the starting payment or energy price, annual escalator, term, service obligations, production terms, transfer process, prepayment rights, purchase options and end-of-term choices. A qualifying offer may require no upfront equipment payment, but it creates a long-term payment obligation and remaining utility charges still apply.

Compare four totals on the same timeline

A responsible decision compares staying with the utility, paying cash, financing ownership and using a lease or PPA over the same number of years. For every path, show estimated utility imports, fixed or base charges, contract payments, financing costs, maintenance responsibilities and any known replacement expense. Keep future utility-rate and equipment-performance assumptions visible.

Do not give one option a favorable assumption that the others do not receive. Use the same household load, weather basis, system size, roof, module model, battery configuration and analysis period. Present a zero-escalation utility case as well as clearly labeled alternatives; historical rate changes are not guaranteed forecasts. If a lease or PPA escalates, show each year's payment instead of only the first month. A comparison that hides the timeline can make unlike offers appear equivalent.

Model California import and export rules separately

The California Public Utilities Commission explains that new customers of the large investor-owned utilities generally take service under the Net Billing Tariff, commonly called the Solar Billing Plan. Imported electricity and exported electricity are not a one-for-one exchange. Exports receive time-varying credits based on avoided-cost values, while imports are billed under the applicable retail tariff. Publicly owned utilities and community-choice providers can have different rules or additional components.

A useful proposal separates on-site solar use, grid imports, grid exports, export-credit dollars, battery charging and battery discharge. It should identify the utility or community-choice provider, current rate schedule, tariff version and assumed permission-to-operate date. Multiplying all solar production by the retail import price overstates the value of exported energy. The expiration of the federal homeowner credit does not change these billing mechanics, so both issues must be modeled independently.

Treat battery incentives as eligibility dependent

California's Self-Generation Incentive Program supports qualifying distributed-energy systems and includes specific residential solar-and-storage equity budgets. The CPUC states that applicants must meet program criteria and directs homeowners to current budget status and program administrators. Income, location, technology, operating requirements and available funds can affect eligibility. Some budgets close, reopen or change.

Do not subtract an SGIP amount from every proposal or promise that a reservation will be approved. Request the budget category, current incentive rate, program administrator, eligibility basis, application stage and party responsible for the paperwork. Compare the project both with and without the incentive until eligibility and funding are documented. A battery can also serve resilience or time-shifting goals, but neither incentive eligibility nor a particular bill saving should be assumed from the presence of storage alone.

Use consumption and roof evidence before choosing size

Gather at least 12 months of utility usage, interval data when available and expected changes such as an electric vehicle, heat pump, pool or additional occupants. Record the rate plan, community-choice enrollment, assistance programs and any existing solar status. Production should be based on the actual roof planes, shade, orientation, equipment and local weather assumptions, not a generic percentage of the latest bill.

Inspect roof age, material, remaining life, structural concerns, vents and electrical capacity before final pricing. A project sized only to maximize a former tax credit could be larger or more expensive than the home's current objective requires. Without that credit, design discipline matters even more: identify whether the goal is bill reduction, backup power, predictable payments, electrification support or some combination, then ask how each proposed component serves that goal.

Verify the contractor and required consumer documents

The California Contractors State License Board's Solar Smart resources tell consumers to verify contractor licensing, review contracts carefully and understand the parties involved. All Star Solar is an independent solar sales organization and authorized sales partner of Axia by Qcells. The contractor assigned to a project and its license information must be identified in the customer's proposal and agreement; another company's license should never be substituted.

Before signing, confirm the seller, equipment owner, finance or PPA provider, installing contractor, warranty issuers and service contacts. Keep the proposal, contract, financing or third-party-ownership agreement, equipment data sheets, warranties, permit documents and interconnection records. Oral statements about a credit, monthly payment, savings, transfer or future purchase price should be reconciled with the written documents before the cancellation period ends.

Ask for a tax-credit-free proposal page

Request one summary page that contains no federal homeowner credit. It should show the gross installed ownership price, financed total if applicable, lease or PPA schedule, estimated remaining utility charges and any incentive only when its eligibility is documented. Ask the seller to label measured facts, current published rates and projections in separate sections.

The page should also disclose the assumed annual household use, solar production, self-consumption, exports, battery losses, degradation, utility escalation and contract escalation. Ask for monthly results, not only an annual total, because California time-of-use prices and export values vary by hour and season. If the project appears acceptable only after inserting the expired credit or an aggressive forecast, that is a decision signal rather than a reason to hide the assumption.

Evaluate home-sale and long-term obligations

Ownership, a loan, a lease and a PPA can affect a future sale differently. An owned system may remain with the property, while a loan can require payoff or other lender steps. A lease or PPA may require buyer qualification, transfer documents, prepayment, purchase or another contract-defined process. The exact agreement controls, not a general promise that transfer is easy.

Review the term, payment changes, lien or security provisions, transfer fees, removal rights, roof-work process, early termination, default remedies, purchase timing and end-of-term options. Ask what happens if the equipment underperforms, the provider changes, the roof needs replacement or the buyer declines the agreement. The absence of a homeowner tax credit does not make any one payment path automatically better; it makes the total obligations and exit provisions more important to compare.

Use a practical 2026 decision checklist

First, verify the project's completion year and do not include Section 25D for a new installation completed after 2025. Second, establish the household baseline from complete bills and the current tariff. Third, make every offer use the same roof, equipment scope, load and analysis period. Fourth, separate imports, exports, storage flows, fixed charges and contract payments. Fifth, test the result without future utility escalation and without unconfirmed incentives.

Finally, read the controlling contract and confirm every project party. Compare cash price, financed total, third-party payment schedule, service scope, transfer rules and end-of-term provisions. Preserve source documents and ask for corrections in writing. The purpose is not to force solar to work after a tax change. It is to determine whether a specific system and payment structure still makes sense for this home on evidence that can be checked.

Know what a responsible conclusion sounds like

A responsible conclusion may be that cash ownership works at the full price, that a loan is too expensive, that a well-understood PPA or lease better fits the homeowner's priorities, or that the project should wait. It may also be that efficiency work, a roof repair, a rate-plan review or a smaller battery deserves attention first. Solar is not automatically a good or bad decision because the federal homeowner credit ended.

The conclusion should state the evidence used, uncertainties that remain and conditions that could change the result. It should not guarantee savings, eliminate the utility bill, promise incentive approval or offer tax advice. For an All Star Solar review, bring a recent bill and the competing proposal. Larry can explain the energy and contract comparison; individual tax questions belong with a qualified tax professional.
