I have been using them since five years and the batteries are still working.
Nissan leaf convert with solar panels on roof.
The idea was that when you got back into the car on a really hot day it wouldn t feel like a cook house.
They used it to power some tiny fans to extract hot air from the car in the summer.
The solar panel trickle charges the batteries very well.
Based on it s size i d assume the amorphous solar panel is only generat.
I am very confident that nissan leaf s spoiler solar panel is even better than my cheap solar panel so it definitely helps keep the 12v battery charged up.
He then spent another 2 400 on solar panels batteries a charge controller.
Back in the early 1990s audi put a similarly sized solar panel onto the roof of the audi a8.
