Solar-powered aircraft areelectricaircraft that can be anairplane,blimp, orairship and use either a battery orhydrogen to store the energy produced by thesolar cells and use that energy at night when the sun isn't shining.
Solar-powered aircraft do not requirefuel, so they don't require oxygen, and they are able to operate ataltitudes over 20 kilometres (12 mi) to 100 kilometres (62 mi) for months at a time.[1][2]
