Home solar is a different animal, the thread is about mobile charging. It's not going to be efficient to lug around a huge solar array. The weight impact to economy alone is likely enough to negate any gains. Even with a 500w setup you are looking at something around 2 miles of range achieved from a "full" day of charging in ideal conditions. That's like 12oz of fuel.I was looking at a 500 watt system, but not just for camping. If I spend 6 hours at the beach 3 times a week, that really starts adding up. Parked in the driveway on sunny days would help too. Planning to use this Jeep for all my short hops around town. We only have one public level 2 station and I dont want to add to my current power bill.
