Lyndon Rive, Elon Musk’s cousin, is planning it for SolarCity:

Economies of scale are part of SolarCity’s plan. The company will manufacture the modules at its new facility in Buffalo, which it hopes to have fully operational by the end of 2017, pumping out enough solar panels to supply 200,000 homes a year. Of course, to hear the CEO say it, we’re already in a pretty good place, cost-wise.

“Solar is not expensive; in fact, there is no cost at all,” SolarCity CEO Lyndon Rive told ThinkProgress. “There are savings on day one.”

This ongoing revolution in making solar panels affordable has made the transition to clean-generated electricity possible. Now if we could just do the same for batteries and other energy storage technologies, we could actually solve climate change — or at least minimize the damage to keep the planet livable in the coming centuries.
