Details on Trina Solar’s new Agile 1P Dual Row tracker design

Written by: Leonard Parker | solar news | April 16, 2021

Trina Solar Co. announced the official worldwide launch of the TrinaTracker Agile 1P Dual Row this week, a new member to the TrinaTracker family right on the heels of the Vanguard series launched in December. The Agile 1P will expand the design possibilities of the TrinaTracker line (with a focus on accomodating higher-power module formats) and has officially gone into mass production. The global installation capacity of TrinaTracker has exceeded 5 GW, with 8 GW annual production capacity on trackers in 2021.

Some highlights from Duan Shunwei, head of Tracker business unit at Trina Solar and Antonio Moralejo Gil, head of Product & Engineering department for TrinaTracker, from the launch conference below.

Three new technologies: Agile 1P leverages an innovative multi-drive (dual-slewing) system and patented spherical bearing to improve the overall stability of tracker system, effectively reducing the system aeroelastic effect, improving load transmission efficiency, avoiding rotation error and enhancing the overall structure. The spherical bearing can minimize the structure stress and deformation and further improve reliability and adaptability in complex terrains. In addition, Agile 1P is equipped with sophisticated stow strategy, preventing the tracker from structural failure in gusty wind and strengthening system reliability. CPP, a world-renowned authoritative wind tunnel test organization, put the Agile 1P tracker through a set of comprehensive wind tunnel tests to prove out the concept.

Installation capacity increases. The Dual-Row design of Agile 1P shortens the tracker length to only 72 meters, enabling installation of up to 120 modules per tracker, and achieving higher installation capacity under the same layout by 15.6%. The “SuperTrack” algorithm can increase the Agile 1P’s total power generation by up to 8%. With the cleaning robot effectively eliminating sands and dust on modules, system power generation can be enhanced by more than 10%.

Optimized BOS. The amount of Agile 1P trackers is reduced by 33%, compared with conventional single-row 1P trackers in a typical 1MW layout, saving 9% in DC cabling. The spherical bearing of TrinaTracker features the self-alignment with an angle adjustability of 30%, which can correct the installation deviation and reduce failure rate as well as operation and maintenance costs. Furthermore, an innovative upgrade to the installation process that integrates the patented Trina-Clamp diminishes installation time by 50%.

In addition, the upcoming TrinaTracker SCADA system will feature remote monitoring, early warning, intelligent diagnosis and troubleshooting. SCADA system will boost the effective operating time under different weather conditions, diagnose the real time tracker problems and perform troubleshooting accordingly, reducing the maintenance costs and increasing solar farm operation efficiency.
