METHOD AND SYSTEM FOR CONTROLLING A HORIZONTAL SINGLE AXIS SOLAR TRACKER

摘要

The invention relates to single axis solar trackers moving solar panels and being controlled by a solar tracker controller. The object of the invention tackles the problem of torque distribution in horizontal single axis solar trackers, in order to distribute the torque along the axis or torque tube, the object of the invention provides a method and a system comprising a plurality of controllers arranged along the horizontal axis, said controllers being associated to actuators intended to operate on the angular position of the torque tube. The controllers are operated in dual role basis, such that a controller acting as master controller performs the calculations of the rotational movements to be induced by the actuators associated to the slave controllers.
