The American-Made Solar Prize Round 4 finalist teams have been working hard over the past few months, preparing to pitch their technology during Go! Demo Day. Since learning of their status as Round 4 finalists in April 2021, these teams have been substantially advancing their solutions from proofs-of-concept to refined prototypes and finding partners to perform pilot tests of the prototypes.

Go! Demo Day marks the finale of Round 4, with two final winners being announced on Sept. 16 at the virtual Solar Prize Demo Day Winner Announcement. Here’s what Round 4 Go! Demo Day will look like:

  • Aug. 25: Teams submitted a 5-minute pitch video.
  • Sept. 15: Teams participate in a private Q&A session with a panel of expert reviewers.
  • Sept. 16: Solar Prize Go! Demo Day Winner Announcement at 2 p.m. ET. Two final Round 4 winners will be announced, each winning $500,000 in cash prizes and $75,000 in technical support. 

The Solar Prize administrators invite all competitors, industry experts, cleantech investors, and anyone interested in solar innovation to join the Solar Prize Round 4 Go! Demo Day Winner Announcement on Thursday, Sept. 16, at 2 p.m. ET. This event is free and open to anyone who wants to find out who wins Round 4.
