At present, apart from automobiles and environmental protection enthusiasts, there are not many researches and developments of auto companies on solar cars. The focus of new energy development is on hybrid power. According to experts, it takes another 30 to 50 years to break through the bottleneck of science and technology and make solar cars formally into people's lives.
The application prospect of solar car power
Solar cars are still in the "concept car" state. Because of the instability and dispersion of solar energy (approximately 1 kilowatt/square meter in strong conditions) and the low efficiency and high cost of solar collectors, solar energy is directly an impenetrable bottleneck for automobiles or bicycles. The outlook is not optimistic. The use of fixed devices to collect solar energy on a large scale to generate electricity and to charge battery cars and battery bicycles is relatively realistic. Now it can be done.
