American-Made Challenges Solar Prize Round 5

Hardware Track


The fifth round of the Solar Prize is designed to spur more solar innovation than ever before by splitting participants into two separate technology-focused tracks. The Solar Prize Round 5 Hardware Track offers $3 million in cash prizes over three progressive contests to competitors who are developing physical solar innovations that energize U.S. manufacturing.

Why a Hardware Track?

The Solar Prize has always placed an emphasis on manufacturing solar innovation in the United States. After four successful rounds focusing primarily on tangible technologies, the prize administrators decided to split Round 5 into two tracks—the Hardware Track and the Software Track. Both follow the same prize structure but allow competitors to stay in different lanes to bring both hardware and software products closer to market.


If your solar innovation focuses on a physical component, manufacturing process, or producible product, the Hardware Track is for you. If your solution is a software technology, you are encouraged to compete in the Software Track. Learn more by viewing the official Hardware Track rules.

The Solar Prize Contests

The Solar Prize encourages the rapid development of innovative solar energy solutions capable of addressing the tough challenges facing the solar industry. Solar Prize competitors participate in three contests—the Ready! Set! and Go! Contests to transform their ideas into concepts and then early-stage prototypes ready for industry testing.


The Hardware Track offers $3 million in cash prizes, plus additional support vouchers and connections to national laboratories and industry resources.
