Today, Assistant Secretary for the Office of Energy Efficiency and Renewable Energy at the U.S. Department of Energy Daniel Simmons announced the two final winners of the Solar Prize Round 3: Maxout Renewables and Wattch Inc. 

These teams were chosen for their impressive innovations that addressed critical solar energy challenges and have the potential to advance the industry. Each team won $500,000 in cash prizes and $75,000 in technical support vouchers. Their technologies include: 

Maxout RenewablesLivermore, CA —This team developed the Evergrid, an appliance powered by a fly-wheel that can turn a residential solar installation into a microgrid that keeps delivering power during a grid outage while the sun is shining. The Evergrid also stabilizes the home microgrid by providing power balancing capacity when appliances like refrigerators cycle on and off.

Wattch Inc.Atlanta, GA — This team developed cost-effective hardware and combined it with secure, scalable software to make a solar monitoring platform to help commercial and industrial PV plants increase operational efficiency. The platform can provide predictive maintenance schedules to decrease downtime, has a universal dashboard that lets PV fleet owners and operators observe the performance of all their systems, improve remote and automated diagnostics, and better model a plant’s lifetime energy yield. 

Congratulations to these two teams for winning the Solar Prize Round 3. We are eager to see your continued impact on solar and beyond!
