At Intersolar Europe in Munich, robotics company QBotix presented their new Robotic Tracking System or RTS. The system uses two small robots, which run along a rail to turn tracker modules according to the sun’s path.
The advantages of the new system are less maintenance-intensive trackers, since these do not have motors and there is no need for extensive land grading or trenching before installation. You can see the robots in action in QBotix’s video:
QBotix has already installed projects in Japan in 2013. In January this year, the company signed a 45 MW supply contract with UK-based developer Castillium and expects the construction to start in September 2014.
