Weather conditions directly affect the power generation of photovoltaic (PV) power plants. Therefore, accurate solar radiation data is a key parameter in evaluating the performance of PV power plants. In PV plant monitoring systems, solar radiation sensors play an important role. Precise real-time measurements and accumulated radiation data are critical for tracking, evaluating, and controlling the performance parameters of PV power plants. For this reason, the accuracy of solar radiation sensors is extremely important.

The TBQ-2WX Solar Radiation Calibrator, developed and manufactured by our company, is specifically designed to calibrate solar radiation sensors installed on site. When deviations occur in the readings of solar radiation sensors at PV stations, it is often difficult to remove the sensors and send them back to the factory for calibration due to time and logistical constraints. The TBQ-2WX Solar Radiation Calibrator was developed to address this challenge.

The calibrator features a portable integrated design, allowing it to be easily transported and used across multiple PV sites. It can be repeatedly utilized for on-site calibration and maintenance, making it an essential tool for the operation and maintenance of photovoltaic power plants.

Principle of Solar Radiation Measurement

Solar radiation monitoring is based on the thermoelectric effect. The sensing element adopts a multi-junction electroplated winding thermopile, with its surface coated with a high-absorption black coating. The hot junctions are located on the sensing surface, while the cold junctions are positioned inside the instrument body. The temperature difference between the hot and cold junctions generates a thermoelectric potential.

Within the linear operating range, the output signal is proportional to the solar irradiance. To minimize the influence of temperature variations, the instrument is equipped with a temperature compensation circuit.

To prevent environmental factors from affecting performance, the sensor is protected by double-layer quartz glass domes, which are manufactured through precision optical cold-processing and polishing.
