TrinaTracker, the tracker systems business of Trina Solar, has unveiled two robots designed to cut installation and operations and maintenance costs at utility-scale solar power plants. Announced on 24 September 2026 from Changzhou, China, the BUILDEX panel installation robot and the AURORA cleaning robot expand the company’s smart photovoltaic (PV) ecosystem.
BUILDEX installs 90 panels an hour
According to TrinaTracker, BUILDEX picks up, carries, aligns and places panels on its own. The robot can install up to 90 panels an hour, three to four times faster than manual installation. Using industrial 3D cameras and AI algorithms for millimetre-level alignment, its platform can level itself on slopes of up to 17 degrees.
BUILDEX works with both fixed-tilt structures and trackers, in single- and double-row (1P/2P) panel layouts with landscape or portrait mounting. A multi-sensor system combining LiDAR and AI supports safety, and the robot is said to be able to work continuously regardless of weather conditions.
AURORA runs unmanned cleaning cycles
The AURORA cleaning robot cleans panels in set cycles without an operator. Powered by its own PV panel and equipped with a self-cleaning function, it can correct height differences of up to 50 mm between rows using its own algorithms. It also offers real-time route planning and active risk prevention.
