From 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.
- steveBK123 4y agoYes, and people don't understand that EVs actually use quite a lot of power relative to a freestanding home. If your home uses gas/oil for heat & hot water, you might only use, say 20kWh/day in winter and 35kWh/day in summer. 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. Your little car roof will generate minuscule amounts of power by comparison to your entire homes roof, while also being at the wrong angle, sometimes parked indoors or in shade, or in motion & not charging during daylight hours.
