Elon Musk's Master Plan - the Solar Roof?

Find out how solar roofs fit into Elon Musk's master plan.  Interesting stuff. Here's an excerpt:

Earlier this month, Elon Musk made news again when he announced his intention to offer solar roofs, a product he sensed might need a few words of clarification.

"It's a solar roof as opposed to a module on a roof," he said on an earnings call about the planned merger between his electric car company, Tesla, with his cousin’s solar panel company, SolarCity. "It's not a thing on the roof, it is the roof."

This wasn’t technically the first mention of the solar roof — it also appeared in Musk’s Master Plan, Part Deux, released in July:

Create a smoothly integrated and beautiful solar-roof-with-battery product that just works, empowering the individual as their own utility, and then scale that throughout the world. One ordering experience, one installation, one service contact, one phone app.

Intriguing indeed. But we don’t have much more information than that.

Since then, the roofs have been called "out of left field," and "a sweeping expansion of Tesla’s clean energy ambitions," but they are neither. Solar roofs are not some side goof of Musk’s; they’ve been part of his ambition all along. People just haven’t been taking him seriously.
