Textured quartz roof tiles with solar cells embedded are designed to look like a traditional clay or slate roof while seamlessly and invisibly integrating solar. This new product is stronger than traditional roofing and eliminates the need for separate solar panels, announced Tesla’s CEO, Elon Musk. He rolled out an update to its energy-storing Powerwall as well. The flatter battery provides 14kWh of storage with a 7kWh power draw, or as much electricity used in a four bedroom house for one day. Musk’s vision is of a home that makes and stores its own power for daily use and for fueling the family electric vehicle. For more information.
