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.

Large-scale solar tracker installation control system

A method of backtracking for a solar tracker installation utilizing a backtracking algorithm to calculate angles of inclination values for the tables of each of the solar tracker assemblies in the solar tracker installation during a backtracking period including morning backtracking period and evening backtracking period periods wherein the calculated table angles of inclination values mitigate undesirable shading of photovoltaic modules of a solar tracker assembly by adjacent row solar tracker assemblies during morning and evening backtracking periods that would otherwise occur with a normal solar tracking mode. Ends of the torque tube beam of each solar tracker assembly are imaged to provide three dimensional coordinates associated with the torque tube beam ends. Vertical position data is input to the backtracking algorithm, taking into account vertical differences of adjacent solar tracker assemblies in calculating table angles of inclination values for each of the solar tracker assemblies during the backtracking period.

Backtracking method for solar tracker installation

A solar tracking system is provided having a pivoting table driven for rotation about an axis of rotation through a rotational angle range. The pivoting table includes a longitudinally extending beam and a plurality of photovoltaic modules supported by and pivoting with the beam. The system also includes an actuator coupled to the beam for rotating the pivoting table about the axis of rotation through the rotational angle range. A controller is provided for activating the actuator to control rotational angular position of the table.
