Solar car solar vehicle used for land transport

A solar car is a solar vehicle used for land transport. Solar cars usually run on only power from the sun, although some models will supplement that power using a battery, or use solar panels to recharge batteries or run auxiliary systems for a car that mainly uses battery power.

Solar car racing refers to competitive races of electric vehicles which are powered by solar energy obtained from solar panels on the surface of the car. The first solar car race was the Tour de Sol in 1985 which led to several similar races in Europe, US and Australia. Such challenges are often entered by universities to develop their students' engineering and technological skills, but many business corporations have entered competitions in the past. A small number of high school teams participate in solar car races designed exclusively for high school students.

Stella (solar vehicles) technical university students team

Stella and its successors Stella Lux, Stella Vie and Stella Era are a series of solar racing family cars, built for the World Solar Challenge in Australia, sofar winning its Cruiser Class all four times it was held – in 2013, 2015, 2017 and in 2019. Stella is considered the world’s first solar-powered family car and was given the 'Best Technology Development' Award at the 8th annual Crunchies in San Francisco in 2015. Being the only competing vehicle with a license plate, the road registration of Stella contributed to the winning score in the races. The vehicles are designed and built by "Solar Team Eindhoven" (STE) — some 26 students of different faculties of the Eindhoven University of Technology (TU/e) in the Netherlands. The group have set up a non-profit foundation to promote their concepts for practical solar vehicles for adoption on a broader scale.
