written by David Belden

How can companies like SunRun, Sungevity, and SolarCity provide a zero down or $1000 down solar lease while charging less per month than a utility company? Sound too good to be true? It’s not. Here’s a high level overview of how solar leases (and PPAs) work.

First, let’s briefly review how a homeowner would purchase and install a solar system without the benefit of a solar lease or PPA.  A home owner purchases
