The sensor unit for advanced monitoring in solar parks

The HSU (Hub Sensor Unit) from the Sunnertracking line by IED Company is an atmospheric sensor unit designed to provide real-time data on environmental conditions in solar parks. This advanced technology is responsible for collecting key information, such as wind speed and direction, snow level, and solar radiation, and sending this data to the Network Control Unit (NCU) to improve the safety and efficiency of solar panels. The HSU is ideal for optimizing the performance of solar parks in any environment, from temperate climates to extreme conditions, thanks to its durability and advanced functionality.

Smart connectivity for efficient and precise management

The HSU integrates an atmospheric sensor system for solar parks, which reads essential atmospheric variables necessary for the safe operation of solar systems. This device measures wind speed and direction, snow level, and solar radiation intensity. These data allow the NCU to make automatic adjustments to the solar panels, protecting the infrastructure during adverse weather conditions and maximizing energy production under optimal conditions. The HSU’s low-temperature models, which operate as low as -30ºC, are equipped with heated wind sensors, ensuring reliable performance even in cold climates.

Versatile connectivity and communication protocols

The HSU is compatible with two communication methods to integrate efficiently with the rest of the solar park infrastructure. The RF version uses a ZigBee module that acts as a router, transmitting data from the HSU to the ZigBee network coordinator, typically the NCU. In the RS485 version, the HSU connects directly to the RS485 bus where the NCU is installed, allowing for fast and stable communication. In both cases, the HSU uses the Modbus protocol, an industry standard, to ensure effective and accurate communication.

Robust outdoor design

Specifically designed for outdoor environments, the HSU features an IP65-rated enclosure that is resistant to water and UV radiation, ensuring durability and functionality in any weather conditions. Its compact size (190x190x130mm) allows for easy integration into the solar park mounting system, while its AC power supply provides a reliable and constant energy source. The HSU is built to withstand extreme temperature variations, making it a dependable choice for solar parks in challenging climates.

Transformative applications of the HSU to optimize solar energy

The information provided by the HSU enables smarter and more efficient management of atmospheric sensors in solar parks, benefiting both the safety and efficiency of the installations:

1. Protection of Infrastructure in Adverse Climates: Data on wind speed and direction allows for automatic adjustment of solar panels to prevent damage during strong winds. Similarly, the snow level sensor prevents excessive snow accumulation on the panels.
2. Maximization of Energy Production: The solar radiation sensor allows the NCU to adjust the orientation of the panels to maximize sunlight capture, increasing energy production under optimal conditions.
3. Monitoring and Preventive Maintenance: The HSU provides critical real-time information that helps detect environmental anomalies, facilitating preventive maintenance and reducing downtime.
4. Adaptation to Extreme Conditions: Thanks to its low-temperature model and heated atmospheric sensors, the HSU maintains functionality in regions with harsh winters, making it a reliable solution for cold climates.

The HSU from Sunnertracking is an advanced solution for environmental monitoring in solar parks, allowing operators to optimize performance, reduce maintenance costs, and ensure the protection of their installations. With its versatile connectivity, rugged design, and precise atmospheric sensors for solar parks, the HSU is the perfect ally to drive success in solar energy generation in any terrain or climate.
