Illustration of the SUNNER product line

TCU

01

The TCU (Tracking Control Unit) is the brain of the solar tracking system. It controls the orientation of the trackers to optimize radiation capture throughout the day. By adjusting the position of the panels in real time, it maximizes energy efficiency and the production of the solar farm. Its role is key from the assembly phase, ensuring accurate installation and optimal performance.

NCU

02

The NCU (Network Control Unit) allows you to manage and store the data generated by solar farms. By integrating real-time information on the performance, efficiency, and status of the panels, the NCU facilitates continuous and detailed monitoring. In addition, by centralizing management, it simplifies maintenance operations and contributes to better control of the solar farm.

HSU

03

The HSU (Hub Sensor Unit) acts as the weather monitoring and diagnostic system in photovoltaic parks. It analyzes weather conditions that could affect the park and issues alerts in anticipation of possible failures. Sunner Tracking’s HSU helps reduce damage and downtime by moving solar trackers to safe positions.

True Wind technology diagram

TRUE WIND enables structural protection for solar trackers against aeroelastic phenomena such as galloping.

  • Intelligent structural stability for solar plants
    TRUE WIND anticipates torsional instabilities in real time, integrating signals from the GAU device using advanced filters and physical models to identify natural frequencies and damping coefficients, dynamically adapting to actual operating conditions.
  • Immediate value for new and existing PV plants
    The solution is compatible with both new designs and existing installations, aligning the actual performance of the tracker with the design parameters to prevent structural damage, reduce maintenance costs, and extend the useful life of the assets.
  • Higher performance, lower operational risk
    By minimizing the time that turbines are unnecessarily in wind-hold mode, TRUE WIND improves the plant’s energy production, optimizes alarm management, and reinforces the operational reliability of the system.

Solar tracking technology for photovoltaic plants

Sunnertracking, IED Company’s line of electronic solar tracking solutions, is designed to maximize the efficiency of solar parks, protect photovoltaic assets, and collect key data on the operation of the facilities. With products such as the TCU, HSU, and NCU, Sunnertracking is a comprehensive solution for those who manage the installation and maintenance of these solar trackers. Our solutions are not only essential for optimizing energy production, but also provide advanced technology and a range of value-added services that make a difference.

Components for the efficiency and safety of solar plants

The TCU (Tracking Control Unit) is the brain of the tracking system, responsible for guiding the solar trackers to make the most of the sun’s rays at any given time of day. By continuously adjusting the position of the panels, the TCU maximizes energy efficiency, helping solar plants achieve higher production without the need to expand the installed surface area. This is especially relevant for those in the assembly phase of these structures, as efficient and accurate installation allows solar trackers to meet their performance targets from the outset. For its part, the HSU (Hardware Supervision Unit) acts as the monitoring and diagnostic system for the farm. The HSU ensures that all parts of the system are functioning correctly, identifying potential faults before they become major problems. This component of Sunnertracking offers significant advantages in reducing maintenance times, one of the key innovations of our product line. By detecting anomalies in advance, solar panel installers and assemblers can schedule timely and rapid interventions, preventing problems from worsening and causing costly downtime in the plant. The NCU (Network Control Unit) allows you to manage and store the data generated by solar plants. By integrating real-time information on the performance, efficiency, and status of the panels, the NCU facilitates continuous and detailed monitoring. This ability to collect and analyze data is key for land buyers and facility managers, who can rely on accurate information to make strategic decisions about their assets. In addition, by centralizing management, the NCU simplifies maintenance operations and contributes to better control of the solar plant.

Customization and after-sales service for optimal performance

One of the great added values of Sunnertracking is its customization capability. We know that every project is unique, which is why we offer solutions tailored to the specific needs of our customers, whether in design, management capability, or associated services. Our after-sales service goes one step further, offering constant support and training to ensure that Sunnertracking solar trackers always perform to their full potential. This service not only covers maintenance, but also includes technical advice on how to maximize the efficiency of the equipment, ensuring a longer service life and optimal performance of the installation.

Innovations to reduce maintenance time and costs

The Sunnertracking product line also incorporates innovative developments that minimize the need for manual intervention. Thanks to its self-diagnostic capabilities and a design that facilitates access to critical components, we have managed to significantly reduce maintenance times. This allows solar panel installers to do their work more efficiently, keeping the solar plant operational for longer and reducing operating costs. In short, Sunnertracking is a robust and advanced solution for those seeking to maximize the performance of their solar plants, especially in the agricultural, commercial, and industrial sectors, renewable energy projects, and public institutions. With products that optimize efficiency, quality after-sales services, and customization options, Sunnertracking is positioned as the ideal choice for those who want reliable, efficient technology tailored to their energy needs.
