PV Weather Station

1.Scope of application of PV Weather Station

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, mainly self-use on the user's side, excess power is connected to the grid and balanced adjustment in the distribution network system.

In order to ensure the normal operation of photovoltaic power stations and data analysis, it is usually necessary to be equipped with a distributed photovoltaic power generation environment monitoring system to monitor indicators such as total solar radiation, surrounding ambient temperature, wind speed and direction, and photovoltaic module temperature.

The distributed photovoltaic power generation environment monitoring system can be connected to the monitoring system, and the monitoring system displays, records and analyzes the data of the environmental monitoring system, or connects to the inverter control system, and analyzes the sensor data by the control system to ensure the effective operation of the photovoltaic power station.
