High Precision Pyranometer Solar Radiation Sensor Photovoltaic Weather Station

 TBQ total radiation sensor adopts the principle of thermoelectric induction and works with various radiation recorders or radiation ammeters to accurately measure TBQ total radiation, reflected radiation, scattered radiation, infrared radiation, visible radiation, ultraviolet radiation, and long-wave radiation from the sun.

The core sensing element of the meter, a wire-wound plated multi-contact thermopile, is coated with a high absorbance black coating. The hot contact is on the sensing surface, while the cold junction is located inside the body, and the hot and cold contacts produce a temperature difference potential. The output signal is proportional to the solar irradiance over a linear range.

The double-layer glass cover is designed to reduce the effect of air convection on the radiation meter, and the inner cover is provided to cut off the infrared radiation from the outer cover itself.

TBQ Total Radiation Sensor Usage:  

The meter is used to measure the total solar TBQ radiation in the spectral range of 0.3-3μm, and can also be used to measure the solar radiation incident to the oblique surface, such as induction face down can measure the reflected radiation, such as adding a shading ring can measure the scattered radiation. Therefore, it can be widely used in solar energy utilization, meteorology, agriculture, building materials aging and atmospheric pollution and other departments to do solar radiation energy measurement.

Since weather conditions directly affect the power production of PV plants, accurate meteorological data and solar irradiance data are indispensable for the core parameters of PV plant performance evaluation.

Meteorological sensors play an important role in PV power plant monitoring systems, and accurate meteorological real-world data is the key to tracking, evaluating and controlling PV power plant performance parameters. Therefore, each PV power plant monitoring system requires a set of meteorological monitoring sensors and several different types of solar radiation sensors to calculate the core evaluation indicators of PV power plants for tasks such as site selection, operation and maintenance management, evaluation, scientific research of PV power production and functional uses such as fault warning. The sampling and processing methods of the data and the way the sensors are deployed and installed can also have a partial impact on the assessment results.

2. Importance of proper use of meteorological sensors: The accuracy of meteorological data is the key to power plant performance assessment. The data acquisition system must have algorithms for outlier detection and rejection to ensure the reliability of the final stored historical data. Since outliers can contaminate the existing database, it is necessary for the data acquisition system to detect the occurrence of these data and deal with them in a timely manner.

3. Importance of comprehensive radiation data for light power prediction: Photometric data is for accurate and actual light power prediction and calculation services, which is crucial for accurate and different areas, different inclination angles and solar radiation values of PV arrays installed on each slope. Statistical analysis of meteorological and radiation data is required, and the data includes wind speed curves, irradiance intensity curves, as well as cloudiness curves and temperature curves.
