Has anyone broken a lease?

The house I'm looking to buy has leased solar panels. It's not a great deal. It's a power purchase agreement. .20 p kwh (my utility PSEG is about .27 (Long Island) with a 2.9% escalator. We would need to pay for all the power the panels generate. There's about 12 years left on the lease. 60 panels.

If I accept the lease transfer I'll be stuck. I'd rather start new with financing panels and pay them off in 12 years.

The seller can purchase the panels but I'm guessing they don't want to spend $40k. They think the panels are wonderful.

I'm waiting for a call back from the transfer resolution team of the solar company to see if there is any loophole in a cancellation. The biggest thing is that the panels were obviously sized for their family so I'm not sure they would meet the demand for us.

EDIT: i need to also say the house is off market and it's very unique. We cannot lose it.
