A control system for a solar tracker assembly installation including a plurality of solar tracker assemblies, each of the plurality of solar tracker assemblies including a table supporting photovoltaic modules and rotatable through an angle of inclination. The solar tracker control system includes: a plurality of solar tracker controllers periodically outputting table angle of inclination data and solar tracker assembly operating data for the associated solar tracker assembly; a plurality of weather sensors, each outputting weather condition data; and an array controller in direct, wireless communications with each solar tracker controller and each weather sensor. The array controller analyzing communicated table angle of inclination data, the tracker operating data and the weather condition data and, as required, wirelessly communicating control signals to one or more solar tracker controllers of the plurality of solar tracker controllers to change a table angle of inclination of the one or more solar tracker assemblies.
