a charging station is a much better idea. So for the solar case, adding a few cells won’t run anything save for some control circuitry. We had about 3 m^2 of solar cells (only 20% efficient, though), and it was just getting enough to get us into the positive power range. regen would be easily doable, and a quick charger could probably get it charged in under an hour of plug-in time. ![]() Now that the long-winded explanation is over… As long as you have good starting torque, the power consumption isn’t a problem really. It was powered off of 3 small lead acid batteries (couldn’t get the li-ion pack working right), so basically a 36v system with 7.2 amp hours. This was also with 20 mph crosswinds and headwinds, and gusting to around 50 mph. ![]() their weird EV conversion factor put us at 2861 mpg, but the actual useful numbers was the fact that we pushed a 158 lb car with a 120 lb driver at around 15-16 mph, using around 170 watts. I just got back from the shell eco-marathon in California, and we had a solar car that kicked some major ass at the competition. 800W is closer to 1 hp (748ish watts/hp), and it’s plenty to move a person.
