Some rough order of magnitude numbers are as follows. It takes about 200 WHs to go a mile, your mileage may vary. If your cart was outside all day, perhaps you get 1000 maybe 1200 WHs of energy from a 200 W panel (angle of the sun matters, as does cloud cover, etc.). This will add 5-6 miles of charge per day. A 1000 WHs from SECO cost about 13 cents (all taxes, fees). So, maybe you save $50/year?
