Tesla CEO Elon Musk has one. And so does Tesla CTO JB Straubel. Both execs are now proud owners of a Solar Roof -- the cornerstone of the company's solar strategy moving forward. Tesla showed off the Solar Roof for the first time last October, wowing a crowd with textured solar tiles made to look like high-end shingles. The company unveiled pricing and started taking orders on the product in May. Musk recently announced the company had recently completed the first Solar Roof installations.
