There is no universal answer, and anyone who gives you one is selling something. Ownership generally produces the strongest long term value. Leasing removes the upfront cost and most of the responsibility. Which one fits depends on your cash position, how long you plan to stay in the home, your tax situation and how much involvement you want in the system.
What changed in 2026 is that the federal incentive no longer sits on the ownership side of the scale, and that shifted the comparison for the first time in over a decade.
Section 25D, the 30 percent federal credit homeowners claimed when they bought a system, expired on December 31, 2025. A purchase made in 2026 with cash or a loan carries no federal residential credit.
Section 48E, the commercial credit, is still active under its own eligibility, timing and sourcing rules. It is claimed by the owner of the system, which in a third party owned arrangement is the finance company rather than the homeowner. Whether and how any resulting benefit is reflected in the price or payment you are quoted is a question for the provider, in writing, on your specific agreement.
Treatment of leases specifically remains an area where rules and guidance continue to develop. Green Additions does not provide tax advice, and we recommend confirming anything tax related with your own advisor before you sign.
The practical takeaway: do not compare options using a 30 percent figure that no longer applies to purchases.
You pay for the system outright and own it from day one.
No monthly payment, no interest, no lender. The lowest total project cost of any route. Full ownership of the equipment and any production it delivers for the life of the system. You are free to modify, expand or add storage later without a third party in the decision.
It ties up capital. With the federal credit gone, the offsetting return that used to arrive at tax time no longer does, so the full cost sits with you upfront.
Homeowners who have the funds available, plan to stay long term, and want the lowest lifetime cost.
You own the system but spread the cost over a term.
Ownership without paying the full amount upfront. You keep the production and the equipment. GoGreen Financing is a California program designed to make clean energy financing accessible at competitive rates without the high dealer fees attached to many solar loan products. Those dealer fees are worth understanding, because they are often buried in the system price rather than shown as a separate line.
You take on a monthly obligation and pay interest over the term. If your loan payment plus the remaining utility charges exceeds your old bill in the early years, the cash flow benefit arrives later rather than immediately. Ask to see the numbers year by year, not just month one.
Homeowners who want ownership and long term value but prefer not to deploy cash upfront.
Ask before signing: the interest rate, the term, whether any dealer fee is embedded in the price, whether the rate is fixed, whether there is a prepayment penalty, and what the payment looks like if you do not make an expected principal reduction.
A provider such as LightReach owns the system and you pay to use the power it produces, typically with no upfront cost.
No upfront payment. A single predictable monthly amount. Maintenance, monitoring and equipment responsibility generally sit with the provider rather than with you. For homeowners without the cash or the appetite for a loan, it is often the difference between having solar and not having it.
You do not own the system, so you do not build equity in it. Many lease agreements include an annual escalator that increases your payment over time, and that escalator needs to be compared against your realistic expectation of utility rate increases rather than against a best case assumption. Term lengths are long, commonly around twenty years or more. When you sell the home, the agreement must be transferred to the buyer or bought out, and that step can complicate a sale if it is not planned for.
Homeowners who want no upfront cost, minimal responsibility, and a predictable monthly figure.
Ask before signing: the escalator percentage, the full term, the total payments over the term, the buyout terms and timing, exactly how transfer at sale works, what happens if the buyer does not qualify, who is responsible for repairs and roof penetrations, and what performance commitment exists if production falls short.
Most comparisons get distorted because they compare a lease payment against a current electric bill and stop there. A fair comparison looks at total cost over the same period for all three routes, what remains on your utility bill in each case, who carries maintenance and repair risk, what happens when you sell, and what you own at the end.
Run all three against the same usage assumptions and the same rate escalation assumption. If a proposal uses a higher utility escalation rate than it uses for the lease escalator, ask why.
Financing structure affects storage too. Under net billing, a battery is often what makes the economics work, so decide early whether storage is part of the project. Adding a battery later to a leased system involves the lease provider, and the options are narrower than they are on an owned system. If storage is likely within a few years, say so during design.
No. Section 25D expired on December 31, 2025. Purchases made in 2026 with cash or a loan do not qualify for the federal residential credit.
Section 48E remains available to eligible owners of qualifying systems under its own rules. The system owner claims it, not the homeowner. Ask your provider directly what that means for your pricing and get the answer in writing.
Not inherently. It is a different product with a different risk profile. It becomes a poor deal when the escalator is aggressive, the term is long, the buyout terms are unclear, or the homeowner was not told they would not own the system. Read the agreement.
The agreement is normally transferred to the buyer, who must qualify, or bought out at closing. Confirm the process and any transfer fee before you sign, not when your house is in escrow.
Cash purchase, in almost every case. Financing adds interest. Leasing adds the provider's margin and escalation. The tradeoff is upfront cost and responsibility.
Owned systems are generally viewed more favorably by buyers and appraisers than systems carrying a transferable obligation. Local market conditions vary.
