I dont even get it how the Tesla guy, managed to sell and promote a single grid tie solar system... in the year 2016, and present it as new technolgy.... besided the fact that it looks good... is so simple and so undertech than other companies producing solar products for the last 20 year... But thas another story, of good marketing and using your fame to make more money...
I would love to put ecocaptule on wheels and ride the world by the way :)
