Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future

by Ashlee Vance

The Rives decided to make buying into the solar proposition much simpler and formed a company called SolarCity in 2006. Unlike other companies, they would not manufacture their own solar panels. Instead they would buy them and then do just about everything else in-house. They built software for analyzing a customer’s current energy bill and the position of their house and the amount of sunlight it typically received to determine if solar made sense for the property. They built up their own teams to install the solar panels. And they created a financing system in which the customer did not need to pay anything up front for the panels. The consumer leased the panels over a number of years at a fixed monthly rate. Consumers got a lower bill overall, they were no longer subject to the constantly rising rates of typical utilities, and, if they sold their house, they could pass the contract to the new owner. At the end of the lease, the homeowner could also upgrade to new, more efficient panels. Musk had helped his cousins come up with this structure and become the company’s chairman and its largest shareholder, owning about a third of SolarCity.
