> It’s really popular on motor homes and narrow boats etc because you can actually get significant amounts of power. Depends what you mean by significant I suppose, but unless you have tons of square footage for panels (like the whole roof of a house), you're not getting a lot of power from solar. Have you done solar installations and tried to live off the power they generate? It all sounds great until you do the math and realize how little power you have. I have both a boat and a travel trailer and spend occasional time living off the grid on both. You quickly learn to be very frugal on power. > a solar car could average 5kWh per day How much roof surface area you'd need for that? Is there a car large enough?
