Abstract

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.
