Round 4 Set! Demo Day
The American-Made Solar Prize Round 4 semifinalist teams have been working diligently over the past several months preparing their technologies for their first event: Set! Demo Day. Since learning of their status as Round 4 semifinalists in December 2020, these 20 teams have been developing proofs-of-concept, performing rigorous customer discovery processes, and cultivating a network of mentors and partners to help advance their technologies.
Now, these innovators will present their products in the hopes of becoming a Round 4 finalist.
