A prepaid solar PPA is one of the strongest ways to go solar in California in 2026, and most homeowners have never heard of it. It gives you much of the savings homeowners used to get from the 30% federal solar tax credit, with no monthly payments, and you own the system in the sixth year. For homeowners in Sunnyvale, Mountain View, Los Altos, Los Altos Hills, Saratoga, Palo Alto, Santa Clara, Redwood City, Cupertino, San Jose, San Carlos, and San Mateo, it has quickly become the smart way to go solar this year.

We specialize in solar panel removal and reinstallation during reroofing. Financing available. Nearly 20 years of experience. We coordinate everything so you never manage multiple contractors.

How a Prepaid Solar PPA Works
A prepaid solar PPA keeps things simple. The structure looks like this:
- A solar system is installed on your roof.
- The system is owned by a third party owner for the first five years.
- You make one upfront payment for a discounted system price, or you finance that payment with a loan.
- You use all the power the system produces.
- In the sixth year, ownership transfers to you at no additional cost.
You pay once, you have no monthly solar bill, and you end up owning the system. The third party owns it during the early years because that is what the IRS rules require for the tax credit to apply.
The 30% ITC Advantage and Why It Still Applies
The residential federal solar tax credit, Section 25D, expired on December 31, 2025 for homeowners who buy with cash or a loan. If you purchase a system outright in 2026, there is no federal tax credit for you.
The commercial Investment Tax Credit, Section 48E, is different. It continues through 2027 for systems owned by a business. A prepaid PPA uses that rule. Because a third party owns the system during the early years, that owner claims the 30% commercial credit on the full installed system, then builds a large part of that value into your lower upfront price.
What that means for you:
- You do not need taxable income to benefit.
- You do not wait until April for a refund. The discount is applied immediately, at purchase.
- There is no tax paperwork or filing on your end.
- You typically pay around 70% of the comparable cash price upfront, with the credit covering the rest.
What You Pay and How You Pay It
You make one payment for the discounted system price. There is no monthly solar payment and no annual escalator. There is no lien on your home. The only filing is a UCC-1 on the solar equipment itself, not on your property.
You can cover the prepaid amount two ways:
- Cash. The cleanest option. You get the full discount and own the system in year six with no ongoing payments.
- Financing. Use a HELOC, a credit union solar loan, Go Green Home, or another lender. Your loan payment goes to the lender, not to the program. With a HELOC, the interest may be tax-deductible. Because the prepaid price already reflects the built-in credit value, your loan amount is lower than it would be on a full-price purchase.
What Can Be Included
Because the whole installed system qualifies for the commercial credit, a prepaid PPA can cover more than panels.
- Solar panels. High-efficiency panels sized for your home and usage.
- Battery storage. A Tesla Powerwall 3, Enphase IQ Battery, or Qcells battery can be included. Under California's NEM 3.0 rules, a battery is essential. It stores your daytime solar and lets you use it during high-cost evening hours instead of exporting it for a low credit. The battery qualifies for the credit as part of the system, and that value is built into your price.
- EV charger. A Level 2 home charger installed as part of the project also qualifies, so the credit value applies to the charger too. If you drive electric or plan to, this is one of the most cost-effective ways to add charging at home.
How a Prepaid PPA Differs From a Traditional PPA or Lease
This is where homeowners often get confused, so it is worth being clear.
In a traditional PPA or lease, the provider owns the system and you pay every month for the power it produces. Because you are paying for production, the provider monitors output and offers production guarantees. That is the whole point of that model.
A prepaid PPA is not that. You prepaid for the system, not for monthly production. There is no monthly bill, no production-based billing, and no production guarantee, because you are not paying per kWh. The equipment carries the manufacturer warranties you would get on any system, the third party is responsible for it during the first five years, and in year six it becomes yours.
Prepaid Solar PPA vs Your Other Options
This comparison shows why many California homeowners choose a Prepaid Solar PPA when combining solar with battery backup and EV charging under current utility rules.
| Option | Upfront Cost | Monthly Utility Bill | Maintenance | 30% ITC Value | Battery | EV Charger | System Ownership |
|---|---|---|---|---|---|---|---|
| Prepaid Solar PPA | One-time prepaid (about 70% of cash price), or financed | Low and predictable | Manufacturer warranties; provider owns years 1 to 5 | Built into your prepaid price | Can be included | Can be included | Transfers to you in year 6 |
| Monthly Solar PPA | $0 | Monthly payment for power produced | System owner | Kept by the system owner | Case by case | Case by case | Stays with third party owner |
| Owned Solar (cash or loan) | High | Low | You, the homeowner | Expired Dec 31, 2025 for cash and loan | Added cost | Added cost | You own it from day one |
The third party owner holds the system for the first five years to claim the commercial tax credit. Ownership transfers to you in the sixth year.
The Case For and Against a Prepaid PPA
The case for it:
- Lower effective system cost, with the credit value built in
- Solar, battery, and EV charger in one project
- No monthly solar payment and no escalator
- The discount is immediate, with no income requirement and no tax filing
- Predictable energy costs, then full ownership in year six
The case against it:
- The system is third party owned for the first five years before it transfers to you
- It is a better fit if you can pay the prepaid amount or finance it than if you want zero upfront cost
- If you specifically want to own the system from day one, a cash or loan purchase fits better
Who a Prepaid PPA Is Right For
A prepaid PPA is a strong fit if any of these apply:
- You want solar savings without a full-price purchase and without the residential credit that expired at the end of 2025.
- You do not have enough taxable income to have used a purchased solar tax credit anyway.
- You want battery backup for outages and peak-hour savings.
- You drive an EV, or plan to, and want to charge at home.
- You want to lock in low energy costs without a long-term monthly payment.
It is not the right fit if you want to own the system outright from day one, or if you plan to move within the next few years without transferring the agreement.
The Prepaid PPA Programs We Work With
We work with more than one prepaid PPA program so we can match the right structure to your situation. Both current programs follow the same core model: a discounted upfront price, no monthly solar payment, no lien on your home, and ownership transferring to you in year six.
- HDM Capital. A prepaid PPA built around the commercial credit and depreciation, with a UCC-1 on the equipment only and flexible ways to finance the prepaid amount.
- Participate Energy. A prepaid PPA following the same upfront, no-monthly, year-six-ownership structure.
As new prepaid PPA programs become available, we fold them in here. During your free estimate, we compare the available programs side by side and recommend the one that fits your finances and goals.

Frequently Asked Questions
Do I own the solar system? Not at first. The system is owned by a third party owner for the first five years, which is what the IRS rules require for the commercial credit to apply. In the sixth year, ownership transfers to you at no additional cost.
Does the 30% federal tax credit still apply? For third party owned systems like a prepaid PPA, yes. The commercial Investment Tax Credit continues through 2027. The owner claims it on the full installed system and passes the value back to you through a lower prepaid price. The residential credit for cash and loan purchases expired December 31, 2025.
Do I make monthly payments? There is no monthly solar payment. You pay once upfront, or you finance that amount with a loan. If you finance, your loan payment goes to your lender, not to the program.
Will there be a lien on my home? No. There is a UCC-1 on the solar equipment only. There is no lien on your home or your property title.
Can a battery and EV charger be included? Yes. Both can be included as part of the installed system, and both qualify under the commercial credit along with the panels. That value is built into your prepaid price. Batteries we install are the Tesla Powerwall 3, Enphase IQ Battery, and Qcells.
How is a prepaid PPA different from a traditional PPA or lease? A traditional PPA or lease charges you every month for the power produced, and the provider monitors output and guarantees production because you are paying per kWh. A prepaid PPA is paid once upfront for the system, so there is no monthly bill and no production guarantee. Ownership transfers to you in year six.
What happens if I sell my home before year six? The agreement transfers to the new buyer, or the buyer can buy out the system at fair market value if they prefer to own it right away. After year six, you own the system outright and sell the home like any home with owned solar. Talk to us before you list so we can help structure it.
Can I finance the prepaid amount? Yes. Many homeowners use a HELOC, a credit union solar loan, Go Green Home, or another lender. HELOC interest may be tax-deductible. Because the prepaid price already reflects the built-in credit value, your loan amount is lower than on a full-price purchase.
Do I need to replace my roof first? If your roof is near the end of its life, yes. Solar should not go on a roof that will need replacement in the next few years. Home Pro handles the roof replacement first and coordinates everything as one project.
Who installs and coordinates the project? Home Pro coordinates the full project, one point of contact for your roof, solar, battery, and EV charger. The solar is installed by our solar partner under the prepaid PPA agreement.
