About the Company

Optivolt

Module-level power electronics for solar optimization

Optivolt Labs makes solar energy more efficient with Balancer power electronics that optimize energy capture inside each solar panel. The Balancer helps counter losses from shade, dust, and aging, so a panel that would normally lose energy under 1% shade can deliver more overall power—claims of up to 25% more energy and up to 60x better output in shaded conditions. They also offer a full-stack solar integration platform for IoT devices, 5G, robotics, and electric vehicles, and sell Balancer units to solar installers, distributors, and manufacturers. Their customers span residential, commercial, and military sectors, including contracts with the U.S. Air Force and funding from the Department of Energy. The company aims to unlock shading-challenged homes, enable self-charging capabilities for electric machines, and broaden solar use by providing integrated energy solutions across civilian and defense markets.
