What's a Prepaid Solar Lease?
Mike Kleeman - December 14th, 2025
This is how I first put solar on my own home. A Prepaid Lease is a Third-Party Ownership model (TPO) where you make one lump sum payment when your system is installed…and then you’re done. No subsequent monthly lease payments, no future out of pocket expenses, hence the term PREPAID. While you don’t technically own the system during the term (the finance company does), you get all the power it produces, plus the peace of mind of battery backup. Your system is fully monitored and maintained, keeping your home powered and resilient for up to 25 years.
You might be thinking, “Why would I lease my system instead of just buying it to own?” The reason is simple: Your one-time PREPAID payment is going to be 15-30% less than buying the system outright for ownership. It affords you the opportunity to capture the kind of savings homeowners used to get from federal solar tax incentives.
Before 2026, you bought and owned solar outright and claimed a 30% federal tax credit. Spend $40,000, get $12,000 back and your real cost was $28,000. That incentive was intended to run through 2032, before it was prematurely eliminated for residential owners at the end of 2025 with President Trump’s Big Beautiful Bill. The key word here being… Residential.
Here’s the twist. The federal tax credit is still alive and well for Commercial owners through 2027.
So, if a TPO financier owns the system, not you, they claim the 30% tax credit. There’s more. Solar and battery equipment also qualifies for accelerated depreciation and is defined as a ‘commercial asset’, meaning the financier can write your system off in just five years. Combine the tax credit with additional write-offs and you have a recipe that significantly lowers the true cost of the system. And that’s precisely why the finance company is motivated to offer you a significantly lower prepaid price. As much as 30% less than if you were to buy the same system outright for ownership.
The choice then becomes: Invest $40,000 cash to own your system with no incentives or do a Prepaid Lease for $28,000 to $34,000 and get the same power, same battery backup and all the guarantees you’d get from owning your system. The bonus with most Prepaid Leases is there is a clear path to ownership, allowing you to buy the system after 5 years for zero dollars if you choose. Full disclosure, I’ve never felt the urgency to do that, because my system already feels like it’s mine and is fully insured, maintained and provides an ironclad warranty for my family.
On paper, a Prepaid Lease is labeled as such for tax purposes, but really, it’s more like ‘Lease-To-Own’ and checks a lot of boxes:
