Editor's Note: This entry has been cross-posted from DOE's Energy Blog.We commonly think that the sun provides free energy. That’s true, but photovoltaic panels and other equipment to harvest that energy aren’t free. The question is: how are they paid for?
U.S. residential and commercial solar system customers have historically paid the old-fashioned way: with cash. But the large upfront cash requirements can place solar energy systems out of reach for many utility customers. Financial markets are responding and increasingly providing solar customers with new options. Purchases can be rolled into mortgage refinances, and consumers can opt to lease solar equipment just as they can lease a car. Others are choosing power purchase agreements, in which homeowners host equipment on their roof or property. In these agreements, homeowners neither buy nor lease the equipment; instead they agree to purchase the power produced.
The growing list of financing options is exciting, but we don’t know much about what type of financing consumers are choosing, how often and with what results.
