The biggest challenge would be the size of the panel; a panel that would charge a golf cart in less than a week would be too big to mount on it. A panel covering the roof of an average house powering a charging station would probably charge it in a day’s time. A far more practical application would be for mobile electronic devices.
Actually, every square meter of solar panel in Florida would produce about 500wh of electricity per day. The roof of a golf cart is about 3 square meters, so you have 1.5kwh per day. That is enough electricity to drive a golf cart about 10 miles per day.
