Structured for Success

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 reality in months, rather than years. Competitors have the chance to win $4.1 million in cash prizes and other resources to help them advance in the competition and accelerate the development of their solution.
