Building a utility-scale solar farm sounds like an engineering problem. In practice, most of the actual work is repetitive manual labor: driving thousands of steel piles into the ground, then bolting and torquing tens of thousands of panels onto racking, one at a time, often in remote sites under a hard deadline. Gritt, a robotics startup founded by two Carnegie Mellon-trained roboticists, exited stealth on July 21, 2026 with a $26 million Series A — led by Obvious Ventures, with Union Square Ventures and Active Impact Investment also participating — on top of $6.4 million raised earlier, bringing its total funding to $32.4 million. Its pitch is narrow and specific: don’t build a new robot from scratch, build an AI-controlled attachment system that turns equipment already sitting on every construction site — excavators, telehandlers, skid steers — into machines that can place and secure solar panels largely on their own.
CEO Puneet Puri and CTO Vishal Dugar started the company after concluding that the hardest part of construction robotics isn’t the robot — it’s getting a machine to work reliably on a real job site, with uneven terrain, changing weather, and equipment operators who have zero interest in learning a new interface. Gritt’s answer was to make the retrofit kit compatible with machinery contractors already own and already know how to operate, rather than asking a solar developer to buy an entirely new robotic fleet. The company previously won $500,000 in cash plus $75,000 in vouchers from the U.S. Department of Energy’s American-Made Solar Prize in 2024, which helped fund its early prototyping before this round.
The Labor Shortage Is the Real Story, Not the Robot
Gritt’s own framing of the problem is stark: the U.S. construction industry is projected to lose 41% of its current workforce to retirement by 2031, at exactly the moment demand for solar farms, data centers, and grid infrastructure is accelerating because of the AI buildout. That combination — shrinking labor supply, exploding demand for the physical infrastructure that supports it — is what’s pulling venture money into construction robotics generally, not just solar-specific attachments. It’s also why investors like Obvious Ventures, better known for climate-focused bets, are comfortable underwriting what is fundamentally an industrial automation company: the addressable market isn’t really “robots that install solar panels,” it’s the entire category of dangerous, physically repetitive construction work that increasingly has no one available to do it.
Attachments, Not New Robots — A Deliberately Boring Strategy
The retrofit-over-replace approach is a strategic bet as much as a technical one. Building an entirely new autonomous machine means clearing a much higher bar on safety certification, cost, and contractor trust before a single unit ships. Bolting AI-driven control systems onto equipment a construction firm already owns sidesteps most of that — the excavator is still an excavator, it just now does part of the panel-placement work with less direct human operation. That mirrors a pattern showing up elsewhere in industrial robotics this year: rather than competing head-on with general-purpose humanoid robots on cost and reliability, several well-funded startups are choosing to automate one specific, painful, high-volume task inside an existing workflow instead.
What This Means for Philippine Founders
The Philippines is in the middle of its own solar and renewable-energy buildout — the Department of Energy has repeatedly pushed to accelerate large-scale solar and wind capacity to meet 2030 renewable-energy targets, and construction labor for that buildout is neither cheap nor infinite here either, particularly with OFW deployment pulling skilled tradespeople abroad. Gritt’s model is a useful template rather than a product Philippine developers can simply import: a retrofit kit built for U.S. equipment standards and U.S. labor costs won’t map cleanly onto a local solar EPC contractor’s fleet or budget. But the underlying thesis — automate the single most repetitive, injury-prone task in a renewable-energy build rather than trying to automate the whole site — is exactly the kind of narrowly-scoped robotics problem a Philippine startup could tackle for the local market, where labor-cost dynamics and equipment availability are genuinely different from Silicon Valley’s. It’s also a reminder to local renewable-energy developers that automation vendors evaluating entry into Southeast Asia will be comparing markets on exactly this kind of skilled-labor availability data — worth having a clear answer ready.
