Bad value versus what? If you invest the same money in a stationary PV grid at home, it is a much better value, that is the point of the article. As I have a PV grid at home I mostly agree with that.
- tomrod 4y agoNice, I like when people add home PV. Is it always an either/or decision then?
- AdrianB1 4y agoFrom an economic and environmental perspective home PV make sense (but the investment takes many years to recover), on cars not at this point, maybe in the future. The article describes options less than 1 KW, at home you put 5-20KW, it's a very different kind of beast.

This matches pretty well with the amount of solar generation you can put on your roof! The cool thing too is that you get more sun in summer, when it is hotter.. and you use more electricity because of the AC.. so it matches pretty well! Now that same 20KwH in winter is enough to fill 20-30% of your battery of your EV to drive 60-80mi.
