Development of an electronic equipment managed by software on PC for controlling and driving of multiple bi-axial solar trackers in photovoltaic solar plants

This paper describes the realization of an electronic apparatus for controlling and driving a bi-axial solar tracker system of a PV plant, managed by a PC software application with an user-friendly graphical interface. The designed software is able to calculate the sun circadian orbit and consequently to move the solar panels in order to maintain the panel´s surface always perpendicular to solar rays, improving the efficiency in energy production. In particular, the object of this work consists in optimizing an existing, from us designed, fully-hardware apparatus which didn´t allow a simple and rapid plant management, completely replacing the Master electronic board with the designed software, able to communicate by PC with Slave electronic boards for tracker motors driving.
