The Solar Car Challenge is an annual event that fosters education and innovation in renewable energy by engaging high school students in the design, engineering, and racing of solar-powered vehicles. Founded in 1989 [ 6 ] by Dr. Lehman Marks, the challenge has grown to become a premier educational program, combining science, technology ...
Solar Cells/Array 5.00-square-metre (53.7 sq ft) array consisting of 318 monocrystalline silicon cells with an approximate efficiency of 22% Seats 4 Chassis Carbon fibre monocoque with foam and an aramid honeycomb core Motors Twin, rear wheel, in hub, synchronous DC motors, both of which are brushless and have permanent magnets Maximum speed
The most popular solar cell material, silicon, has a less favorable band gap of 1.1 eV, resulting in a maximum efficiency of about 32%. Modern commercial mono-crystalline solar cells produce about 24% conversion efficiency, the losses due largely to practical concerns like reflection off the front of the cell and light blockage from the thin ...
The American Solar Challenge (ASC), previously known as the North American Solar Challenge and Sunrayce, is a solar car race across the United States. In the race, teams from colleges and universities throughout North America design, build, test, and race solar-powered vehicles in a long distance road rally -style event.
The Formula Sun Grand Prix (FSGP) is an annual solar-car race that takes place on closed-loop race tracks. In the race, teams from colleges and universities throughout North America design, build, test, and race solar-powered vehicles. Every two years the race serves as a qualifier for the American Solar Challenge road race. [1]
Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.
A combination of high-efficiency silicon solar cells and maximum power point trackers are used to extract the maximum possible power from the available solar energy and feed it into a lithium iron phosphate battery pack. The vehicle is driven by a specially designed axial flux wheel motor via a custom controller, resulting in higher efficiency ...
The Eco-Marathon has different classes of competition, according to the energy source used: Fuel cells, solar cells, gasoline, Diesel fuel and LPG. During the competition, cars must attain an average speed of at least 15 mph (23 km/h) over a distance of 10 miles (16 km). The course is typically a motor racing track or closed-off city streets.
