The 2P configuration and the fewer-pile design features significantly reduce balance of system (BOS) costs, especially for harsh soiling and scenarios with higher pile requirements. Those harsh environments are increasing in prevalence globally with the decrease of flat land for solar plants.
Vanguard 2P (single-axis two-in-portrait tracker) was first released by TrinaTracker in 2021 and is the company’s main product. Its patented spherical bearing prevents misalignment and minimises friction and reduces installation time and cost. The continuous module and tracker R&D capability of Trina Solar makes it perfectly compatible with ultra-high power modules and maximises power generation of solar plants. By the end of 2022, TrinaTracker had delivered 3 GW of Vanguard 2P trackers globally.
The second generation of Vanguard 2P uses a multi-motor control system to replace the original mechanical method. In the new drive system, the main controller sends commands and the secondary controller receives commands to drive the motors. The self-developed intelligent mechanism enables the synchronisation of multiple motors to avoid potential structure failures, which can save time and costs on operations and maintenance.
Besides the multi-motor control system, the second generation of Vanguard 2P also improves the structure’s compatibility with larger-sized modules up to 695W. All these improvements reduce system costs, lower levelized cost of energy (LCOE), and better fit the most challenging sites.
“For the past few years, we’ve seen more projects in sites with slope terrains, deserts, and near coastal regions” said Andrew Gilhooly, Head of Trina Solar Asia Pacific. “This requires solar components to meet more severe quality standards and include more innovative developments to operate under those harsh scenarios. The second generation of Vanguard 2P aims to successfully solve such challenges.”
