About the company

Charge Robotics builds robotic systems that automate solar installation work to remove labor bottlenecks in construction. Their robots handle tasks in the field to speed up the process of deploying solar projects, allowing construction teams to install more systems in less time. This focus on automation of on-site installation differentiates Charge Robotics from competitors that only provide components or software rather than end-to-end robotic labor solutions. The company’s goal is to help the world switch to renewable energy faster by making solar installation scalable and more efficient.

Simplify's Take

What believers are saying

  • Solar delivered 81% of new U.S. electric capacity in 2024, expanding demand sharply.
  • The $22 million round funds commercial launches and manufacturing scale after prototype validation.
  • Multiple factories per site compress schedules without adding labor, a compelling EPC value proposition.

What critics are saying

  • First commercial deployments still target late 2025; slippage signals product-market mismatch.
  • SOLV Energy remains the proof point; one customer leaves revenue concentration dangerously high.
  • If field uptime or installation economics disappoint, EPCs keep crews and Charge stalls permanently.

What makes Charge Robotics unique

  • Portable robotic factories assemble solar fields in 40-foot sections onsite, not offsite.
  • March 2025 SOLV Energy pilot proved automated installation on a working solar farm.
  • MIT founders Banks Hunter and Max Justicz focus narrowly on utility-scale solar labor.

Charge Robotics raises $22M to automate utility-scale solar farm construction

Charge Robotics, founded by MIT alumni Banks Hunter and Max Justicz, has raised $22 million to deploy its portable robotic factories for utility-scale solar farm assembly. The company plans to begin commercial installations later in 2025. The factories automate solar panel installation, which currently relies on manual labour. In early 2024, Charge deployed a prototype system with SOLV Energy, successfully building a working solar farm. The system works like a portable assembly line. Steel tracks, mounting brackets, and panels are loaded in, and the factory robotically assembles them into 40-foot sections. A robotic vehicle positions each completed bay in the field. Solar accounted for 81% of new US electric capacity added in 2024, but labour shortages constrain growth. Charge's system allows multiple factories to run simultaneously at sites, completing projects faster without expanding the workforce.

Robotics Investments Near $1B In August

Listen to this articleSwiss-Mile raised $22M in August 2024 for its wheeled quadruped. Fifty producers of robots and robotics enabling technologies received funding in August 2024, pulling in a total of approximately $1 billion. This figure is on par with the $1.2 billion average The Robot Report has tracked each of the previous 12 months. Investment targeted to robotics companies for the first eight months of 2024 equals about $10.86 billion. You can follow The Robot Report‘s investment section here. The largest investments in August were secured by developers of autonomous driving technologies
