Just in time for roofing season, Elon Musk releases the solar roof tiles, presumably for real this time. (In the initial release, they weren’t operational.) The Powerwall2 is twice as powerful and at $5500, a much better return on investment. See his vision in the video: solar + battery + transportation. He sees rooftop solar not as competition for utilities; we will need both. You’re not going to run a cement plant on household solar. Utilities will have to grow to accommodate the switch of all energy toward renewable electricity.
