About Charge Robotics

Charge Robotics is a Berkeley-based startup founded in 2021 by MIT alumni Banks Hunter and Max Justicz, building robots that automate the most labor-intensive aspects of solar farm construction. As a Y Combinator company that has progressed through Series B funding, Charge Robotics addresses a critical bottleneck in renewable energy deployment where skyrocketing demand for solar installations is constrained by labor logistics rather than technology or financing. Their flagship Sunrise system is a fully automated solar construction robotics platform designed to assemble and install solar-tracking hardware, significantly accelerating the pace at which utility-scale solar farms can be built. The company has raised a total of $39.1 million across four funding rounds, including a recent $22 million Series B in March 2025 led by Climate Capital. Other investors include Y Combinator, UpHonest Capital, E14 Fund, FoundersX Ventures, Gaingels, and Hummingbird Ventures. Charge Robotics has partnered with Solv Energy, one of the largest solar contractors in the United States, to validate their technology through pilot deployments. The Series B funding is being strategically allocated to refine their technology, expand the engineering team, enhance manufacturing capabilities, and scale production for commercial deployments. By removing the labor constraint, Charge Robotics enables construction companies to meet rising solar demand and helps accelerate the global transition to renewable energy.
