Buying a home is complicated enough, but buying a house that comes with a solar power purchase agreement adds even more math to the decision.

As shared by a prospective homebuyer in Reddit's r/solar community, buying a home with a 12-kilowatt solar system under a 20-year power purchase agreement in year four is a complicated decision. The reason is that the seller won't buy out the contract, meaning the new homeowner would need to assume it at $127 per month with a 3% annual escalator.

"They will not pay off the lease, I have to take it or leave it," the original poster wrote. "12 kW system will produce more electricity than we use on a yearly basis, my electric company allows us to accrue surplus generated energy indefinitely. So when I get an EV, I will be able to use that accrued energy."

It is important to understand the distinction between owning your panels and leasing. Owning typically delivers the biggest long-term savings and boosts home value, while third-party agreements like PPAs can be more complex, especially during resale. That doesn't mean solar itself is the problem. Either way, solar can help homeowners shield themselves from the energy inflation that is occurring around the world.

For homeowners who are set on owning their own system, EnergySage offers a suite of free tools to compare quotes, find incentives, and get the best deal on a rooftop array.

Smart upgrades that slash monthly bills

Installing solar panels remains one of the most powerful ways you can cut your utility bills, shield yourself from rising electricity rates, and make your home more resilient. Here are some tools to help you get started on lowering your bills with rooftop solar.

For this homeowner's situation, the fixed monthly payment and built-in annual price increase immediately raised eyebrows among commenters.
