The following submission statement was provided by /u/darth_nadoma:

The Berkeley lab study finds that one of the factors that has helped to
expand access to rooftop solar is the use of leasing and other
third-party ownership models. By leasing panels or subscribing to a
local community solar project, a customer can use solar without having
to pay high upfront costs. The main drawback is that third-party
ownership usually means less savings for the consumer.
