Prepaid Leases Are Reshaping How Americans Pay for Solar
Prepaid solar leases are transforming how homeowners access clean energy. Discover their benefits and the future of solar financing!
The residential solar industry built its growth story on one foundational promise: buy a system, claim your 30% federal tax credit, and let the math work in your favor. That promise is now off the table for homeowners. Section 25D — the residential solar tax credit — is gone, and the industry is scrambling to replace the financing engine that drove millions of installations.
The answer it's landing on is the prepaid lease, and it's more elegant than it sounds.
What a Prepaid Solar Lease Actually Is
A prepaid lease isn't just a renamed product; it's a structurally different financial arrangement that routes federal incentives through a commercial entity instead of the homeowner.
Here's how it works: a solar provider or financier owns the rooftop system. Because the provider is a commercial entity, it can claim the Section 48 commercial Investment Tax Credit — still sitting at 30% — which is completely unavailable to individual homeowners under current law. The provider then passes that credit value to the customer as an upfront discount on the total system cost. The homeowner writes one check, pays for 25 years of solar electricity in advance, and walks away with a lower effective cost than they'd pay for the same system outright today.
The counterintuitive result: a financing model built around third-party ownership can actually deliver a lower price point than direct purchase, precisely because it unlocks tax benefits the homeowner can't access alone.
If the installer uses U.S.-manufactured hardware, a 10% domestic content bonus stacks on top of the base 30% ITC. That pushes the total discount to 40% of system cost — a number that genuinely changes the purchase calculus for households sitting on the fence.
The ownership structure comes with a built-in transition. For the first six or seven years, the solar provider handles all maintenance. That window isn't arbitrary; it's the IRS's requirement for the provider to legitimately claim the commercial tax credit. Once that period closes, the homeowner has the option to buy out the system for a nominal fee and take full ownership for the remaining life of the panels, typically another 18 to 20 years.
Why Section 25D's Expiration Matters More Than It Seemed
When the residential tax credit expired, the initial reaction from some corners of the industry was measured. After all, the credit had lapsed and been renewed before. But this expiration landed differently — it came alongside a broader policy environment that made revival feel less certain, and installers couldn't afford to wait.
The practical fallout was immediate. Without Section 25D, a homeowner considering a $30,000 solar installation could no longer reduce their federal tax liability by $9,000. For most middle-income households, that credit wasn't just a bonus; it was the variable that made the math work. Remove it, and the payback period stretches, the monthly loan payment climbs, and the sales conversation gets harder.
Third-party ownership models don't solve the underlying policy gap, but they reroute the incentive so the financial benefit still reaches the customer — just through a different legal structure.
What's notable here is that the commercial ITC wasn't expanded or modified to accommodate this shift. Section 48 has always existed. Installers are simply now finding it worthwhile to build product structures around it because the residential alternative has closed. That's an industry adapting in real time, not waiting for Washington.
What This Means for the Homeowner
From a customer's perspective, the prepaid lease removes two significant friction points: tax complexity and maintenance risk.
Under a traditional solar loan or cash purchase, the homeowner has to actually owe enough federal income tax to absorb the credit. A family with $9,000 in credits but only $6,000 in tax liability has to carry the remainder forward — or loses it entirely if their situation changes. That calculation made some customers hesitant and required installers to spend real time in the sales process explaining tax liability concepts that most people understandably find opaque.
Prepaid leases eliminate that conversation entirely. The discount is baked into the price. The customer sees a lower number and doesn't need to think about IRS Form 5695.
The maintenance coverage during the initial service term also shifts risk in a meaningful way. Inverter replacements, panel issues, and system monitoring headaches are the provider's problem for the first several years — the exact period when a new system is most likely to surface hardware or installation defects. After that window, the homeowner can acquire a system that's already been running for years, with a documented performance history, for a small buyout fee.
Who's Building for This Moment
Two programs are worth watching as early examples of how this model gets productized.
All Energy Solar's EnergyLock and SolSource's Propel both use the prepaid lease structure and are designed to layer in the domestic content bonus where possible. Michael Allen, CEO and co-founder of All Energy Solar, framed it directly: the goal is letting customers benefit from commercial solar incentives "while enjoying long-term energy independence on their own roofs."
That framing matters from a sales perspective. One of the persistent anxieties around any lease structure — prepaid or monthly — is that the homeowner doesn't actually own the equipment on their roof. The prepaid model addresses that objection by design: the ownership transition is built into the contract from day one, with a clear timeline and a defined buyout path.
For installers, the sales process simplification may matter as much as the economics — replacing a complex tax credit conversation with a straightforward discount is a genuine operational improvement.
The domestic content angle is also worth unpacking. The 10% bonus for U.S.-manufactured hardware creates a direct financial incentive to specify American-made components. In a market where procurement decisions are often driven purely by price, that bonus changes the competitive position of domestic manufacturers in a real and immediate way. Whether the module supply chain can scale to meet increased demand is a separate question — but the demand signal is now clearer.
Where This Goes From Here
Ohm Analytics, presenting at a Roth Capital Partners webinar, projected that prepaid offerings could reach roughly 10% of U.S. residential solar market share by the end of Q4 2026. That would push the overall share of third-party owned products to somewhere between 60% and 65% of the financing mix.
Those numbers represent a genuine structural shift. For most of the past decade, the industry moved steadily toward direct ownership — loans displacing leases as customers became more financially sophisticated and wanted to capture the tax credit themselves. That trend has now reversed, not because homeowners changed their preferences, but because the policy environment changed the math.
The longer-term question is what happens if the residential tax credit returns. Some version of that debate will likely play out in Congress over the next few years. If Section 25D is reinstated, the calculus shifts again — and installers who've built their businesses around prepaid lease infrastructure will need to decide whether to maintain that capability or pivot back toward direct ownership models.
But that's a problem for another policy cycle. Right now, the prepaid lease is the most practical tool the industry has for keeping residential solar accessible. Installers who move early to build relationships with financiers, get comfortable with domestic content sourcing, and train their sales teams on the new conversation will be positioned better than those still waiting for the old playbook to come back.
The credit is gone. The opportunity isn't.
