Although I’m not a huge fan of the depot, this is big news for renewables. I have solar and am just waiting for the powerwall to become a little more affordable. Then it’s an electric car for sure. Some people don’t understand this about home solar — if you are grid tied and produce only 100% of your electric needs, adding an electric car would end up causing a significant not negative balance on the meter. But adding the powerwall, or other battery system, would allow you to store a lot of the energy produced during the day when you aren’t actually much of it. So without adding more panels to the array, the powerwall would make an electric car very cheap to charge.
