‘SuperTrack’ incorporates a smart tracking algorithm that increases energy production by between 3% to 8% compared with conventional tracking algorithms. The system combines Smart Tracking (STA) and Smart Backtracking (SBA) algorithms to enhance energy production, particularly during periods of overcast weather, highly diffuse irradiance and with complex, uneven terrains.

STA optimizes power production for bifacial modules in highly diffuse irradiance conditions based on 12 different parameters included in the Trina Bifacial Irradiation Model. This logically results in a significant quantity of additional information in comparison with data obtained via the four parameters used by astronomical algorithms. STA also 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. Firstly, UAV sensing technology and power generation data simulate terrains and shading three-dimensionally. Then, the optimal backtracking angle is accurately defined by a machine learning algorithm and a proprietary Mini-Shading model.

The SuperTrack system incorporates pyranometers and snow sensors, data from these being shared between NCUs. When a sensor fails, the tracker’s operation is not affected and energy production remains high. SuperTrack also integrates protection strategies which are actively responsive in extreme weather conditions.

The system 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.

José Carlos Talavera, Head of Project Fulfilment and Global Customer Services for TrinaTracker, commented at the launch: “We are very excited to launch SuperTrack, a control monitoring system that, as part of our TrinaTracker whole solution portfolio, significantly boosts our clients’ return on investment by increasing energy production by up to 3%-8%. I strongly believe that TrinaTracker is setting a new benchmark in the PV industry by developing an artificially intelligent solution, the performance of which goes way further than what is achieved by existing conventional tracker applications.”
