Round 4 Go! Demo Day

The American-Made Solar Prize Round 4 finalist teams have been working diligently over the past year preparing their technologies for the competition finale: Go! Demo Day. Since learning of their status as Round 4 finalists in April, these teams have identified pilot test partners and used continual customer and stakeholder feedback to substantially advance their solutions from proof-of-concept to prototype. Now, these innovators will present their products in the hopes of becoming a Round 4 finalist.
