American-Made Solar Prize

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 July 9, 2020, DOE launched Round 4 of the American-Made Solar Prize. In the first phase of the competition, entrepreneurial individuals and teams pitch an innovative idea that addresses a critical need in the solar industry and identify market demand for it. Those selected to advance to the second phase will design a proof-of-concept. In the third and final phase, selected individuals and teams will develop early-stage prototypes for industry testing. 

The fourth round of the Solar Prize will run concurrently with the third round, which was announced in September 2019.
