Energy Transition/ Private Equity & Venture Capital

Power electronics company Optivolt announced that it has raised $32 million in a Series A funding round, with proceeds aimed at advancing its platform to build an intelligence layer for solar energy, turning passive solar hardware into adaptive power systems to adapt to different conditions and maximize energy output in a real-world setting.
Founded in 2017 by CEO Rohit Kalyanpur, San Francisco-based Optivolt develops solar power electronics and intelligent panel technology. The company’s solutions integrate power management, monitoring and safety functions directly into solar panels, reducing the need for separate hardware components and supporting the operation of residential and utility-scale solar systems.
The company said that conventional solar panels can experience significant energy losses when individual cells underperform, reducing the output of larger sections of a panel. Optivolt’s Power Balancer technology addresses this issue by redistributing energy among groups of cells in real time. The system replaces conventional systems and integrates rapid shutdown and monitoring capabilities, reducing the need for separate power optimization and safety equipment.
Optivolt noted that internal testing found that panels incorporating its technology produced up to six times as much power as panels using bolted-on optimizers under defined shade scenarios.
The new capital will be used to expand manufacturing and deployment of its technology across residential and utility-scale solar projects, including projects designed to help power AI data centers, according to the company.
Kalyanpur said:
“For nine years, we’ve rebuilt the solar panel from first principles, embedding aerospace-grade power electronics so it can respond to Earth as it actually is, not the ideal conditions of a lab. The result is the first solar panel system that thinks for itself – one that adapts to shade, weather, dirt and degradation in real time, recovering energy conventional solar leaves behind.”
The new funding round was led by VXI Capital, a new hard tech fund founded by the former CTO of the Defense Innovation Unit of the U.S. Military, with additional participation from RA Capital, Valo Ventures, and Atlas Innovate, bringing Optivolt’s total capital raised to date to $42 million.
Orin Hoffman, Managing Director at VXI Capital, said:
“The next era of energy will not be built by simply installing more of the same passive solar panels we already have. It will be built by making solar intelligent enough to become the backbone of the global power system. Optivolt has spent nine years building the architecture for that future. This financing is about taking it from a technical breakthrough to the platform on which the next generation of solar is built.”
