PV Weather Station

1.Scope of application of PV Weather Station solution

PV Weather Station is used to monitor key meteorological parameters that affect the efficiency of photovoltaic power generation for the production of photovoltaic power stations.Distributed photovoltaic power generation refers to photovoltaic power generation facilities that are built and operated at or near the user's site, with the main features of self-generation and self-use on the user side, excess electricity connected to the grid, and balanced regulation in the distribution network system. In order to ensure the normal operation and data analysis of photovoltaic power stations, it is usually necessary to equip distributed photovoltaic power generation environmental monitoring systems to monitor indicators such as total solar radiation, ambient temperature, wind speed and direction, and photovoltaic module temperature. Distributed photovoltaic power generation environmental monitoring systems can be connected to the monitoring system, which displays, records, and analyzes the data of the environmental monitoring system. They can also be connected to the inverter control system, which analyzes the sensor data to ensure the effective operation of the photovoltaic power station.
