Is the SolarCity Model the Only Way to Scale Residential Solar?
The U.S. residential solar market is growing rapidly and undergoing a major transformation at the same time. A new acquisition, partnership, or project fund seems to be announced every week.

SolarCity and Vivint Solar, the top two residential installers in the U.S., installed more than one-third of all residential systems in 2013 and raised more than half of the $2.3 billion in project funds announced last year. (We’ll discuss more finance trends in an upcoming update to last year’s U.S. Residential Solar PV Financing report.) The two companies have very different strategies, especially when it comes to acquiring customers. Vivint is known for selling exclusively door-to-door, while SolarCity has a diversified approach that includes retail partnerships, cold calling, advertising, and anything else you could think of.

Across these and other finance providers, the TPO model has proven easy to scale given the large addressable market of consumers who can afford a lease but not the purchase of a system.
