Gritt exits stealth with $32M for AI-controlled robots that install solar panels 4x faster

Gritt (two Carnegie Mellon-trained roboticists) raised a $26M Series A led by Obvious Ventures, on top of an earlier seed, for AI software that bolts onto off-the-shelf construction equipment (e.g. Kawasaki arms) to pick, place, and position solar panels. The company says an 8-person crew normally installs about 800 panels a day; with Gritt's system the same crew installs 3,000 to 4,000 a day, with tens of thousands placed so far at zero breakages. Gritt has agreements to support 2.8 GW of solar installation over the next 18 months and wants the same intelligence to eventually generalize to other outdoor construction tasks.

What it means This is the applied-floor case the practitioner bar asks for: a named, measured productivity multiplier (roughly 4-5x panel-installs-per-day) on a real deployed system, not a lab demo or an announcement — directly useful to a construction or renewable-energy business owner sizing whether physical-AI robotics is worth evaluating today.
