The Solar Prize encourages the rapid development of innovative solar energy solutions capable of addressing the tough challenges facing the solar industry. Solar Prize competitors participate in three contests—the Ready! Set! and Go! Contests to transform their ideas into concepts and then early-stage prototypes ready for industry testing. Competitors have the chance to win $3 million in cash prizes and other resources to help them advance in the competition and accelerate the development of their solution.
Anyone with a big idea for solar can participate.
