The 30% Tax Credit Is Gone. This 20% Discount Isn't.

Let's get the uncomfortable truth out of the way first. The 30% federal solar tax credit — the one that put solar within financial reach for millions of American homeowners — expired on December 31, 2025. It's gone. 

But there's an incentive available right now that most solar companies aren't talking about — probably because they don't offer it, or they don't fully understand it. It's called a Prepaid PPA/Lease agreement, and for the right homeowner, it applies a discount of 17% to 30% directly to your total cost at signing.

That's not a small number. On a $20,000 solar system, 17% is $3,400 back in your pocket on day one. At 30%, you're looking at $6,000 off the top. And unlike the tax credit, this doesn't depend on how much you owe in federal taxes. 

First, Let's Make Sure We're On the Same Page 

You already know what a standard PPA (Power Purchase Agreement) or Lease looks like. You sign a contract with a third party, they install solar panels on your roof, and you either pay for the power those panels generate (PPA) or rent the system itself (Lease). The panels technically belong to the financing company, not you. 

For years, these agreements got a bad reputation — and honestly, some of that reputation was deserved. Long contracts, escalating rates, complicated transfer processes when selling a home. A lot of homeowners who could qualify for a loan stayed away from PPAs and Leases for good reason. 

But here's what changed. A Prepaid PPA/Lease flips the model on its head. Instead of making monthly payments over 20-25 years, you pay for the agreement in full — upfront, all at once. And because the financing partner is collecting the full value of the contract immediately instead of waiting years to get paid, they pass a significant portion of those savings directly to you in the form of a discount. 

That discount is where the 17-30% comes from. You're paying in full today, and the financing partner is rewarding you for eliminating their collection risk. 

How the 17-30% Upfront Discount Actually Works 

When you finance solar through a standard loan, the lender is exposed to risk over the life of the loan — interest rate changes, defaults, economic shifts. They build that risk into the interest rate you pay, which is part of why solar loans often carry rates between 5% and 10%. 

With a standard PPA or Lease, the financing company faces a different kind of risk: they're collecting small payments every month for 20 to 25 years. A lot can happen in 25 years. People move. Situations change. Even at low default rates, that's a long time to wait to be made whole. 

When you choose a Prepaid PPA/Lease, you eliminate that risk entirely. The financing partner gets their money today. In return, they apply a discount to the total contract value — and that discount is what gives you the 17-30% reduction in cost. 

Think of it like buying a hotel room. If you book a fully refundable room for next month, you pay full price. If you prepay and commit now, the hotel offers you a discount because they’ve locked in the revenue. Same logic applies here. 

This matters a lot in 2026, because the homeowners who benefited most from the 30% federal tax credit were those with a high enough federal tax liability to actually claim it. If you owed $8,000 in federal taxes, you got $8,000 worth of benefit. If you only owed $2,000, you only claimed $2,000 that year — and had to roll the rest forward. 

The Prepaid PPA/Lease discount doesn't care what you owe in taxes. It doesn't require you to wait for April. It's built into your contract value from the moment you sign. 

State Availability: Where the Prepaid PPA/Lease Is Currently Offered 

This incentive isn't available everywhere, and the discount percentage can vary by state based on local regulations and financing structures. Right now, IntegrateSun offers Prepaid PPA/Lease agreements through our financing partner in the following states: 

Texas 

Texas homeowners can access the full Prepaid PPA/Lease product, covering both solar panels and battery storage systems. Given Texas's unique grid environment — and the growing interest in battery backup after the February 2021 winter storm — this is particularly relevant for homeowners looking to pair solar with a Tesla Powerwall or similar battery. 

California 

California is one of the strongest markets for this product. With NEM 3.0 fundamentally changing the economics of grid-tied solar, the case for battery backup has never been stronger in California. The Prepaid PPA/Lease is available here for full solar-plus-storage systems, and the upfront discount helps offset some of the sting of the new export compensation rules. 

Colorado 

Colorado homeowners can access the Prepaid PPA/Lease for solar and battery systems. Colorado has strong solar resources and, depending on your utility, some favorable rate structures that make locking in your solar costs upfront a smart financial move. 

Oklahoma 

Oklahoma is an often-overlooked solar market, but it has solid sunlight resources and lower-than-average electricity rates — which actually makes the upfront Prepaid structure even more attractive, because you're locking in predictable energy costs before utility rates climb. 

Nevada 

Nevada's abundant sunshine and history of shifting net metering policies make it a strong candidate for the Prepaid PPA/Lease. Paying upfront insulates you from policy changes that could affect the value of your solar exports over time. 

Pennsylvania 

Pennsylvania homeowners have access to the Prepaid PPA/Lease for full solar systems. Pennsylvania has some strong state-level Solar Renewable Energy Credits (SRECs) that can stack on top of a Prepaid agreement, making the overall economics quite favorable. 

Arizona — Battery Only 

Important Note for Arizona Homeowners: In Arizona, the Prepaid PPA/Lease is currently available for battery storage systems only — not standalone solar panel systems. If you're an Arizona homeowner who already has solar installed and is looking to add battery backup, this is a compelling option. If you're looking for a full new solar installation, your IntegrateSun consultant will walk you through the alternatives available in your area. 

Who Is a Prepaid PPA/Lease Actually Right For? 

This is where we get honest with you — because the Prepaid PPA/Lease isn't the right choice for every homeowner. Here's how to think about it. 

It works really well if... 

• You have the cash available to pay upfront and aren't planning to use it for something else in the near term. 

• You're planning to stay in your home for at least 7-10 years. The upfront discount is most valuable when you have time to realize the full energy savings. 

• You had low federal tax liability and wouldn't have claimed the full 30% tax credit anyway. The Prepaid discount has no tax requirement. 

• You want predictable, fixed solar costs without worrying about interest rates or monthly payments. 

• You're in one of the seven states listed above. 

It may not be the right fit if... 

• You don't have liquid capital available and would need to finance the upfront payment itself — at that point, a standard loan likely makes more sense. 

• You're planning to sell your home in the next few years. While prepaid agreements can transfer to new buyers, it's worth discussing the implications with your IntegrateSun consultant before signing. 

• You're in a state not currently covered by the Prepaid PPA/Lease product. 

• You're in Arizona and want a full solar system rather than battery-only. 

The best way to know if a Prepaid PPA/Lease is right for you is a direct conversation about your specific situation — your energy usage, your state, your tax picture, and your plans for the property. That's exactly what IntegrateSun consultations are designed for. 

What About Ownership?

Let's address the elephant in the room, because it comes up every time someone considers a PPA or Lease product. 

You don't own the panels. With a Prepaid PPA/Lease, the solar equipment technically belongs to the financing partner. You own the energy the system produces. You own the reduction in your electricity bill. But the hardware on your roof belongs to someone else. 

For some homeowners, that's a dealbreaker, and we respect that. Ownership matters to a lot of people, and if you want to own your panels outright, a cash purchase or a solar loan is the path you should take. 

But for others, the ownership question is less important than the financial outcome. And here's the honest math: if a Prepaid PPA/Lease saves you $4,000 to $6,000 upfront compared to a cash purchase, and you have no maintenance responsibility because the financing partner handles system performance, some homeowners find that trade-off entirely acceptable. 

It's also worth knowing: maintenance and performance guarantees are typically included in a Prepaid PPA/Lease. If the system underperforms, the financing partner is responsible — not you. That's a level of protection that cash buyers and loan customers don't automatically get. 

Prepaid PPA/Lease vs. Your Other Options in 2026 

With the federal tax credit gone, these are the realistic options available to most homeowners right now: 

Cash Purchase 

You pay full price for the system and own it outright from day one. Maximum long-term value, but requires significant capital and you absorb all maintenance responsibility after the warranty period. Without the 30% tax credit, the payback period is longer than it used to be. 

Solar Loan 

You finance the system and pay it off monthly over 5-20 years, depending on the loan. You own the panels. Interest rates currently range from 5-10% depending on your credit and the lender. Good option if you want ownership and don't have large amounts of liquid capital. 

Standard PPA/Lease (Monthly Payments) 

You pay monthly for either the power or the system rental. No upfront cost, but you're locked into payments for 20-25 years, often with escalating rates built in. Generally the least financially optimal long-term structure. 

Prepaid PPA/Lease (What We're Talking About Today) 

You pay in full upfront — but at a 17-30% discount off the total contract value. No monthly payments. No maintenance responsibility. The discount effectively replaces a significant portion of what the federal tax credit used to provide. 

None of these options is universally "best." The right choice depends on your financial situation, your state, your tax picture, and what you value most. IntegrateSun will walk you through all four options and show you the real numbers for your specific system before you make any decision.  

What Happens Next

If you're in Texas, California, Colorado, Oklahoma, Nevada, Pennsylvania, or Arizona (for battery systems), the Prepaid PPA/Lease may be one of the most financially compelling solar options available to you right now. 

Here's what we recommend: 

• Get a free consultation with IntegrateSun so we can assess your specific property, energy usage, and financial situation. 

• Ask your consultant to run the numbers on all four options: cash purchase, solar loan, standard PPA/Lease, and Prepaid PPA/Lease. See them side by side. 

• Find out the exact discount percentage available in your state, since the 17-30% range reflects variation across our service areas. 

• If you're in Arizona, ask specifically about the battery-only Prepaid structure and whether your home is a good candidate.
