So, the big problem with off grid solar is that battery packs are very expensive. But with the onset of electric cars, people may be investing in large and expensive batteries anyway. Seems like this could be the perfect solution for someone looking to eliminate all ties with the utility company without buying a special battery just for home solar.
I saw some postings online about the Nissan Leaf being able to feed energy from the battery back to the grid at night or even during the day (during high demand). Is this something that Tesla is looking at offering or do they already have such a system available?
Does this idea appeal to anyone else? Why or why not?
