Solar Prize Framework and Support

The American-Made Solar Prize is a $3 million competition designed to revitalize solar manufacturing in the United States. Competitors may be entrepreneurial students, professors, small-business owners, company staffers, researchers at national laboratories, or anyone else based in the United States with a potentially marketable solar technology solution. This challenge requires competitors to make progress on a condensed timeline, form private-sector partnerships, and secure investments to make their ideas a reality.

On March 22, 2019, Round 2 of the American-Made Solar Prize was launched. To participate, competitors must identify a critical challenge related to American solar manufacturing competitiveness, create a proof of concept, and secure a partner to test a prototype. Competitors will participate in demonstration days, where they will pitch their ideas. At these national events, a panel of expert reviewers will evaluate competitors based on the quality of their solution and the progress made during the contest period.

The second round of the Solar Prize will run concurrently with the first round, which was announced in June 2018.
