Well if you cannot afford to pay for the panels, you cannot afford to replace batteries every 3 to 5 years either. Off grid solar will cost you 10 times more than buying the power. And if in Canada, even higher.Solar- That's a really good idea for them if I can't use them for an EV. I just can't afford the solar panels, and build the EV. Also, I don't own a house at the moment.
