The race towards energy efficiency in the photovoltaic tracker market has news. Manufacturer Trina Solar presented an algorithm that can increase energy generation between 3% and 8%.
According to the company, this effectiveness varies according to each project, the aspects of the terrain and the climate in each location.
In the “Technical Manual on Intelligent Tracking Technology SuperTrack”, the characteristics and advantages of the SuperTrack, which, according to the company, has three differences:
- Both intelligent tracking and backtracking technologies;
- An online communication system that reduces cabling costs and speeds up the operation of solar trackers;
- Efficient protection techniques against extreme weather conditions, such as strong winds, snow and hail.
Still according to Trina, the SuperTrack It also brings solutions to existing flaws in traditional algorithms. The manufacturer claims that it is a tracking technology that takes into account the local climate and reduces shading losses generated by the spacing between the rows of bifacial panels during the backtracking.
Furthermore, the product, certified by CGC (China General Certification), analyzes the total generation performance of high-power bifacial panels. With this, the manufacturer claims to be able to fully exploit the advantages of single-axis trackers, reducing LCOE (levelized cost of energy) and improve payback.
“CGC and Trina evaluated the feasibility of the algorithm during the initial phase of the project, which led us to recognize the advanced profile of the solution and design a specific empirical technology. During monitoring, CGC attested to the data accuracy and effectiveness of the SuperTrack,” said Zhou Gang, general director of CGC Solar Energy Division.
Other advantages
Another point highlighted by Trina is that the algorithm combines tests in wind tunnels and simulations to increase the reliability and O&M (Operation & Maintenance) efficiency of the tracker.
“Associated with the wide application of bifacial modules, the SuperTrack will help single-axis trackers jump-start energy gains, which will help further reduce LCOE and increase the use of trackers in the global photovoltaic industry,” highlighted Duan Shunwei, head of TrinaTracker business unit at Trina Solar .
