Gritt exits stealth with $34 million for robots to build solar plants—then, everything else
Gritt, a robotics start-up founded by two Carnegie Mellon-trained roboticists, has exited stealth mode with $34 million in total funding to build AI-controlled robotic systems that install solar panels, aiming to address a labour shortage slowing the global solar build-out. Rather than developing bespoke robots, the company adapts off-the-shelf hardware, such as rented skidders and robotic arms, guided by its own AI models, arguing that recent advances in AI now allow machines to cope with the unpredictable conditions of outdoor construction sites in ways they previously could not.
The Series A round of $26 million was led by Obvious Ventures, with Union Square Ventures and Active Impact Investment also participating, adding to an earlier seed round backed by First Round Capital, Climactic, Congruent Ventures and VSC Ventures. Gritt's systems currently unload and position glass solar panels with sub-millimetre accuracy, and the company claims an eight-person crew using its technology can install 3,000 to 4,000 panels a day compared with roughly 800 without it. It is already contracted to help install 2.8 gigawatts of solar capacity over the next 18 months for customers including three of the top ten US power construction firms, and hopes to have 48 systems deployed within six months, putting it in competition with rivals such as Luminous Robotics, Cosmic and China's Trinabot.
- Gritt raises $34m total to build robots that install solar panels
- Robots reportedly boost crew installation rates four to fivefold
- Firm already contracted for 2.8GW of solar installs within 18 months

Gritt is a robotics start-up, founded by two roboticists trained at Carnegie Mellon University, that has just gone public with its plans after operating in secret ("stealth mode"). Its core idea is to use AI-guided robots, built from adapted off-the-shelf equipment rather than custom-designed machines, to help install solar panels at large solar power plants. The company argues this is now possible because AI has advanced enough for machines to handle the unpredictable conditions of outdoor building sites.
The push behind this is a shortage of workers, which is slowing down the construction of solar farms worldwide as demand for renewable energy grows. Gritt says its robotic systems can significantly speed up panel installation compared with manual labour, and it has now raised $34 million in total from investors including Obvious Ventures, Union Square Ventures and First Round Capital to expand the business.
This matters because solar installation is a fast-growing but labour-intensive industry, and automation could reshape how quickly and cheaply large solar projects get built. Gritt is not alone in this space: it faces competition from other firms, including companies in China, all racing to bring robotics into renewable energy construction.
