Solar cars combine technology typically used in the aerospace bicycle alternative energy and automotive industries.
The design of a solar vehicle is severely limited by the amount of energy input into the car. Most solar cars have been built for the purpose of solar car races.
Exceptions include solar-powered cars and utility vehicles.
Solar cars are often fitted with gauges as seen in conventional cars. In order to keep the car running smoothly the driver must keep an eye on these gauges to spot possible problems.
Cars without gauges almost always feature wireless telemetry which allows the driver's team to monitor the car's energy consumption solar energy capture and other parameters and free the driver to concentrate on driving.
Solar cars depend on PV cells to convert sunlight into electricity. In fact 51% of sunlight actually enters the Earth's atmosphere.
Unlike solar thermal energy which converts solar energy to heat for either household purposes industrial purposes or to be converted to electricity PV cells directly convert sunlight into electricity.
When sunlight ***photons*** strike PV cells they excite electrons and allow them to flow creating an electrical current.
PV cells are made of semiconductor materials such as silicon and alloys of indium gallium and nitrogen. Silicon is the most common material used and has an efficiency rate of 15-20%.
