A group of 10 teams have been selected as finalists in Round 1 of the American-Made Solar Prize, a $3 million competition aimed at revitalizing U.S. solar manufacturing, administered by the US Department of Energy’s National Renewable Energy Laboratory (NREL).
 
Each of the finalist teams will be awarded $100,000 from the second phase of the competition, called the Set! Contest. These competitors are now eligible to continue to the final phase of the competition, the Go! Contest, for an additional $500,000 in cash prizes awarded to up to two winning teams. The range of innovations represented by the competitors include cell and device-related concepts as well as module and application hardware.
 
The finalists in the Set! Contest are:

• BREK Electronics Corp. is developing transformative, silicon-carbide-based composite architectures for string inverters;
• Catalyst is accelerating rooftop solar by offering a cost-effective plug-in “solar appliance” that simplifies rooftop solar installation and expedites project payback;
• Crystal Sonic is using a novel wafering technology to dramatically reduce substrate cost and improve reuse for gallium arsenide-based solar cells;
• Imagen is introducing an efficient, compact, next-generation multi-port Power Electronics Systems for revolutionizing the future of PV solar and EV applications;
• Omnisole is developing a revolutionary ballasted racking system that greatly reduces installation time, with no roof penetrations, and can be used on steep roofs;
• Phase3 Photovoltaics is designing a novel power integration system that enables PV systems to be integrated on manufactured homes during the manufacturing process;
• Solar Guardian is creating a low-cost device that prevents electrical fires in photovoltaic modules, enabling safer and lower cost solar system installations;
• Solar Inventions is creating a new cost-effective photovoltaic cell design that increases power, improves shading response, decreases hotspot risks, and produces a more reliable module;
• Solar SEED is creating innovative voltage controller hardware to offer flexible and scalable basic energy access and emergency backup power for a new generation of the solar market;
• Tandem PV is creating an innovative photovoltaics tandem solar cell prototype using a combination of high-efficiency perovskite material plus silicon in a tandem solar cell.

 Finalists were chosen by a panel of expert judges at a national demonstration day event at Greentown Labs in Boston from 20 teams, a subset of the original pool of more than 150 submissions in Round 1.
 
“The progress made by our finalists is very promising,” said Debbie Brodt-Giles, prize administrator for NREL. “We’ve seen them test the viability of their ideas and make quick progress with the help of our industry partners and members of the American-Made Network. The best part of this competition is the partnership between the Network and teams, watching them quickly overcome hurdles and accelerate progress toward their prototyping and market-ready potential.”
