The American-Made Solar Prize is a $3 million competition designed to revitalize solar manufacturing in the United States by supporting entrepreneurs as they develop transformative technology ideas into concepts and then into early-stage prototypes ready for industry testing.

The first round of the competition ran from June 2018 to September 2019. Innovators from around the country competed in the first stage of the competition, the Ready! Contest, by identifying an impactful idea or solution that addresses a critical need in the solar industry and then developing a path to make their solution a reality. Twenty teams were selected as semifinalists by a panel of expert reviewers and received $50,000 each from a pool of $1 million.

The semifinalists moved on to the second phase of the competition, called the Set! Contest, to design a proof of concept and identify market demand for their solution. In June 2019, 10 teams were selected as finalists to receive $100,000 in funding and $75,000 in vouchers to use at the National Laboratories and elsewhere within the American-Made Network to advance their prototypes.

In the last phase of the competition, the Go! Contest, the finalists demonstrated their prototypes before a panel of expert judges at Solar Power International in September 2019. Two winners were selected and received $500,000 in cash and up to $75,000 in vouchers to use at the National Laboratories and qualified fabrication facilities in the United States. The winners are: 

Phase3 Photovoltaics (Portland, OR) – Prefabricated Solar Systems: This team developed a solution that integrates solar into factory-built homes. By incorporating solar cells in the manufacturing process, they are able to provide their solar home solution at a substantially lower cost per watt as compared to traditional installation.
