SunRun PPA Question

Hello, first time home buyers with a new build home in San Diego that has Solar panels from SunRun. We have the chance to lease or buy the panels outright for $11K.

Talking to SunRun, they are offering a flat rate of $0.25/kwH for a PPA. This has no Annual Escalator tied to it for 25 years and they said we can purchase the Solar panels after 5 years, 20 years and 25 years. Comes with monitoring and performance guarantees.

But is there a catch? I see myself saving money monthly on power and the upfront cost as well. Am I just paying for the PPA and also the lease for the panels? Or just the PPA? Anyone have similar experiences?

Thanks!
