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.
