QBotix Brings Robots to the Solar Farm

QBotix Brings Robots to the Solar Farm

QBotix has a genuinely innovative solar solution that maximizes output and could lower balance-of-system costs in ground-mounted PV installations. The startup has invented a two-axis tracker system where the motors, instead of being installed two per tracker, are moved around by a rail-mounted robot that adjusts each tracker every 40 minutes, resulting in an enormous reduction in the number of (failure-prone) motors. The modular system envisioned by the startup consists of 200 1.5-kilowatt trackers maintained by a hot-swappable robot and backup robot for the 300-kilowatt section. It looks like this: The robot visits each assembly, adjusts the angle and tilt, and moves to the next pole. When its job is done, it parks itself in a little hut and dreams of electric sheep . There's no doubt that single-axis trackers add value to a solar farm -- tracking the sun east to west can...
