Photovoltaic weather station

1.The scope of application of the photovoltaic weather station scheme

Photovoltaic weather station, also known as photovoltaic power generation meteorological environment monitoring system, is a system developed by photovoltaic weather station for solar resource assessment and power generation monitoring, which is used to measure the surface temperature, wind speed, wind direction, ambient temperature and humidity, total radiation and other environmental parameters of solar modules.Distributed photovoltaic power generation refers to photovoltaic power generation facilities that are built and operated at or near the user's site, mainly for self-use on the user's side, with surplus electricity connected to the grid and balanced and regulated in the distribution network system. In order to ensure the normal operation and data analysis of photovoltaic power plants, 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 distributed photovoltaic power generation environmental monitoring system can be connected to the monitoring system. The monitoring system can 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 can analyze the sensor data to ensure Effective operation of photovoltaic power plants.
