Optivolt

Module-level power electronics for solar optimization

Overview

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.

Optivolt raises $32M to embed power electronics "brain" in solar panels

Optivolt, a San Francisco power electronics company, has raised a $32 million Series A led by VXI Capital. RA Capital, Valo Ventures, and Atlas Innovate also took part, bringing its total funding to $42 million. The company's Power Balancer puts active electronics inside a solar panel. It shifts energy among cell groups in real time to recover power lost to shade, weather, dirt, and uneven wear. More than 20,000 panels with the technology have shipped. Optivolt will use the money to expand manufacturing and bring the product to systems from homes to utility-scale projects. In internal tests, panels with the technology produced up to six times as much power as those with bolted-on optimizers under defined shade scenarios.
