The present invention relates to an automobile toy, and more particularly to a solar electric vehicle toy that is driven by using the electrical energy generated by the solar cell.

As environmental issues arising from global greenhouse gases have become a global concern, automobile makers and automobile related organizations in each country can replace gasoline cars, which are considered as the leading causes of pollution, such as electric cars, hydrogen cars, and solar. Development of automobiles using batteries is being actively conducted, and a lot of researches are being conducted on these trends and batteries, delayed explosion of hydrogen, and solar cells, which are the main power sources of air pollution-free vehicles. Especially in Korea, where no crude oil is produced, much research on this should be done.
