Founded in 2019 and headquartered in San Francisco, Charge Robotics raised approximately $5 million to address the significant labor constraint in solar installation — a bottleneck that threatens the pace of US commercial solar deployment needed for decarbonization goals. Charge Robotics' robot (the SunBot) is designed to navigate commercial rooftops, pick solar panels from palletized stacks, and precisely place them in the correct position — a task that requires significant physical labor and exposes workers to rooftop fall hazards. The automation targets the repetitive, physically demanding portion of installation (panel handling and placement) while human installers focus on electrical connections, inspections, and quality control. In 2025, Charge Robotics operates in the nascent construction robotics market for solar installation, with few direct competitors developing comparable roof-mounted autonomous installation systems. The commercial solar market is growing rapidly driven by IRA incentives, corporate renewable energy procurement, and decreasing panel costs — but installer labor supply has not kept pace with demand, creating a genuine market for automation. The company's commercial viability depends on demonstrating that robot-assisted installation can significantly increase crew productivity on commercial rooftop jobs. The 2025 milestones focus on fleet deployment on commercial installations, demonstrating productivity improvements versus manual installation, and securing contracts with solar EPC (engineering, procurement, construction) companies. ## Frequently Asked Questions ### What is Charge Robotics?
