Tesla is coming out with a solar roof that is compatible with their updated battery that can then charge their car. The cost of the roof is supposedly comparable to the cost of a roof plus your current electricity bill. Telsa has recently purchased Solar City as it’s distribution channel. I look forward to see how this technology unfolds.
