The thin solar panels placed on golf carts convert the sun's energy into charge for the cart, which takes it off the electric grid, and increases drivign distance and battery life; they are widely used by owners who drive long distances, or have fleets of carts.
Solar golf carts are golf carts powered by mounting a photovoltaic (PV) or thin film panel on top of the existing roof or using a PV panel as the roof itself. A controller converts the sun's energy to charge the golf cart's 36-volt or 48-volt battery bank. Not only does the solar power take the cart off the electric grid, it also increases the driving distance and extends the life of the batteries. Solar-powered golf carts are popular with owners who drive long distances, such as maintenance workers, golf course fleets, staff at the Detroit Zoo, transportation vehicles in resorts and cities, and drivers of VIP carts on college campuses.
