24/7 Monitoring for PV Operations: The Role of Tianqiong's Photovoltaic Weather Station

The Photovoltaic Weather Station under Tianqiong enables precise, real-time, and continuous monitoring. Specifically designed for the photovoltaic industry, it accurately detects key meteorological parameters that affect photovoltaic power generation. In particular, regarding solar radiation, it can precisely distinguish between direct radiation and scattered radiation, and accurately measure the intensity of solar radiation reaching the surface of photovoltaic panels, providing accurate data for evaluating the actual light-receiving efficiency of photovoltaic panels and optimizing the installation angle and layout of the panels. The high-precision temperature sensor can monitor the ambient air temperature and the backsheet temperature of photovoltaic panels, grasp the impact of temperature on power generation efficiency, and provide a reliable basis for power station operation and maintenance.

The 3D ultrasonic anemometer detects wind field changes in real-time, which not only can evaluate the natural cooling effect but also can early warn of strong wind risks for safety precautions.

The real-time monitoring function allows the Photovoltaic Weather Station to timely feed back meteorological information. Various sensors automatically and quickly collect meteorological data at set short intervals, and transmit these data to the monitoring center in real-time through data transmission technology. Power station operation and maintenance personnel can check real-time meteorological parameters such as light intensity, temperature, humidity, and wind speed around the photovoltaic power station, as well as indicators like the surface temperature and output power of photovoltaic modules at any time through monitoring software. When there is an abrupt change in meteorological conditions, such as a sudden drop in radiation intensity or excessive wind speed, the system can instantly and automatically trigger an early warning mechanism, promptly notifying operation and maintenance personnel via text messages, emails, etc., so that they can quickly take response measures to prevent and mitigate disasters.

The Photovoltaic Weather Station can work 24 hours a day without interruption. It can continuously record meteorological data, forming a long-time-series dataset. The large amount of historical data accumulated through such continuous monitoring is of great significance for analyzing the long-term operating performance of photovoltaic power stations, evaluating the changing trends of power generation efficiency, and formulating scientific maintenance plans. By in-depth mining of historical data, operation and maintenance personnel can accurately grasp the operating rules of photovoltaic power stations under different seasons and weather conditions, predict potential problems in advance, reasonably arrange equipment maintenance and overhaul work, effectively reduce operation and maintenance costs, and improve the overall economic benefits of photovoltaic power stations.
