Photovoltaic weather station

1. Scope of application of solar radiation comprehensive observation station program

Photovoltaic weather station is a monitoring device for photovoltaic power stations, which can be used to monitor the meteorological environment around photovoltaic power stations.Distributed photovoltaic power generation refers to photovoltaic power generation facilities that are constructed and operated at or near the user's site. They are mainly self-contained on the user side, with excess electricity connected to the grid and balanced 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 a distributed photovoltaic power generation environmental monitoring system to monitor indicators such as total solar radiation, ambient temperature, wind speed and direction, and photovoltaic module temperature. The comprehensive solar radiation observation station can be connected to the monitoring system, and the monitoring system will display, record and analyze the data of the environmental monitoring system. It can also be connected to the inverter control system, and the control system will analyze the sensor data to ensure that the photovoltaic power station effective operation.
