Suntrack 10

The SUNTRACK 10 is a microcontroller-based system, ECU (Electronic Control Unit), which has been designed to follow up on two axes with high precision. It is suitable for all types of PV modules most common, including photovoltaic panels, concentration systems and heliostats.

The control modules, working in open loop, calculate the relative position of the Sun (astronomical events), both Elevation and Azimuth, with a precision of 0.01 °. In closed loop, the system has a solar sensor that works when there is enough radiation directly and includes an auto adjustable function   for the sensor solar and photovoltaic tower, eliminating the need for very precise adjustments in the alignment between the sensor mechanical solar and photovoltaic tower.

The solar follower has two communication ports for RS 485 MODBUS. One for configurig software, allowing maintenance and operation. The other allows the integration of the system of central control of the plant site, through the monitoring software.
