Solar-powered aircraft are electricaircraft that can be an airplane, blimp, or airship and use either a battery or hydrogen to store the energy produced by the solar cells and use that energy at night when the sun isn't shining.
Usage
Solar-powered aircraft do not require fuel, so they don't require oxygen, and they are able to operate at altitudes over 20 kilometres (12 mi) to 100 kilometres (62 mi) for months at a time.[1][2]
Solar Airship One is being developed by Euro Airship and is planning to launch a would tour in 2026 and fly by 25 countries in 20 days as it travels around the world non-stop.
It will be autonomous and use electrolysis to store hydrogen to keep moving at night when the sun isn't shining.[11]
