Hi....if you just expect 7-10 hours of max speed out of your savaging engine seven days a 50 watt board and regulator would work. 50 watt board is $200-250, and a fundamental charge regulator is $50. Morningstar makes great modest regulators and there are quite a few boards, google look for 50 watt sun powered board. PM on the off chance that you need more point by point data.
