During the earnings call Elon seemed to imply that the Solar Panels at supercharger stations would provide enough energy to get them close to self sufficient. He said that many people do "back-of-the-envelope" calculations but they don't consider that they are charging up a battery all week. I would really like this to be explained to me since it is very frustrating that he would insist on this when it seems misleading. Going by the picture on the website I see a 5x20 solar panel array. When I do a quick search it looks like the average solar panel has peak power of about 200 watts which could translate to 1.6 kWh/day in the summer. In an array of 100 panels that is 160 kWh/day or a little more than 1mWh/week. So, assuming on average people will pull 40 kWh in a charge that is 25 charges covered by the weekly output of the solar panels. I have a hard time believing superchargers will not be far more popular than this.
Can anyone tell me where I'm wrong?
