A photovoltaic power plant in Shandong Province, China, recently faced operational and maintenance issues as well as decreased efficiency due to its aging technology. To address this, TrinaTracker, a leading provider of smart tracker solutions under Trina Solar, performed a smart upgrade by utilizing its own developed TCU and NCU to replace the aging electronic control system.

This upgrade addressed communication barriers and enhanced security defense mechanisms. TrinaTracker's meticulously designed stow strategy automatically activates in strong winds, intelligently adjusting trackers based on real-time weather data to mitigate risks from inclement weather. Additionally, the TCU identifies motor overload, triggering stow programs to prevent structural damage from overcurrent and ensuring long-term stability and safety.


To maximize the power plant's potential, TrinaTracker integrated SuperTrack smart algorithms equipped with Smart Backtracking Algorithm (SBA) and Smart Tracking Algorithm (STA).

SBA constructs a 3D map using terrain data, enabling real-time detection and self-learning optimization of parameters, maximizing tracker advantages. STA utilizes a bidirectional radiation model to determine the optimal tracking angle in cloudy and rainy conditions, minimizing rotation and extending operational time.

The integration of Trina Smart Cloud revolutionized existing operational and maintenance practices, enhancing overall operational efficiency through features like real-time monitoring, rapid fault detection and display, data sharing, digital mapping, and status diagnostics.

The O&M company overseeing the power plant highly praised TrinaTracker's "Comprehensive Technological Reform Strategy," which resolves operational faults significantly and ensures robust system operation through the integration of digital monitoring and intelligent tracking technologies.

In the rapidly evolving solar industry, technological innovation is the driving force behind its advancement. TrinaTracker's smart control system is deployed worldwide, with contracts exceeding 6.2GW in 16 countries and regions. With a customer-centric approach, it continuously improves and innovates systems through on-site projects and collaborative efforts, leading to cost savings and increased efficiency in PV power plants. It is expected to accelerate the evolution towards new types of power systems in the future.
