TrinaTracker’s SuperTrack includes a Smart Tracking algorithm that increases energy production by up to 3% to 8% compared with the conventional tracking algorithms. SuperTrack intelligent tracking combines Smart Tracking (STA) and Smart Backtracking (SBA) algorithms to enhance energy production, particularly during periods of overcast weather and highly diffuse irradiance and complex, uneven terrains. STA optimizes power production for bifacial modules in highly diffuse irradiance conditions considering the 12 different parameters included in the Trina Bifacial Irradiation Model. STA reduces tracker rotation times, extending the durability of the motors. SBA minimizes energy generation losses resulting from row-to-row shading in PV plants installed in terrains with multiple slopes. First, UAV sensing technology and power generation data simulate terrains and shadings three-dimensionally. Then, the optimal backtracking angle is accurately defined by a machine learning algorithm and the Mini-Shading proprietary model. SuperTrack smart control system includes pyranometers and snow sensors, which data is shared between NCUs. Therefore, when a sensor fails, the trackers' operation is not affected, and energy production remains high. SuperTrack also integrates protection strategies actively responsive in extreme weather conditions. SuperTrack software provides monitoring and control with a user-friendly interface that displays target tracker and real angles, batteries, TCU and NCU monitoring, an alarm system with data storage and recording, real-time meteorological information and SuperTrack parameters.
