Photovoltaic Solar Environmental Monitoring System

Photovoltaic Solar Environmental Monitoring System

Accurate measurements are of course of primary importance for solar PV power systems or solar application research. The indicators to be monitored include, in addition to solar radiation, many environmental factors that have an impact, such as the basic supply of the system, ambient temperature, module temperature, wind speed, wind direction, light composition, and other meteorological parameters that have an impact on the light energy conversion products.

Introduction to Photovoltaic Solar Environmental Monitoring Systems:

In order to ensure the normal operation of PV plants and data analysis, it is often necessary to have a weather station to monitor indicators such as light intensity, ambient surrounding temperature, and PV module temperature. The weather station can be connected to the monitoring system, which displays, records and analyzes the data from the weather station. It can also be connected to the inverter control system, which analyzes the sensor data to ensure the effective operation of the PV plant.

Let's take a look at the case of foreign PV solar environment monitoring system on PV cluster power station

Foreign work in this area has been very mature, as an auxiliary system, photovoltaic solar environmental monitoring system in addition to the monitoring of meteorological parameters, in addition, there are similar current, voltage or inverter status monitoring.

Case of small weather station for PV power plant:

The parameters monitored by the domestic PV power plant small weather station are generally ambient temperature, module temperature, wind speed, wind direction and radiation intensity. It mainly consists of main collection box, total solar radiation collector, wind speed and wind direction collector, outdoor ambient temperature sensor (need to add outdoor light louvered box), surface temperature sensor, total radiation sensor, wind speed sensor, wind direction sensor, 485 communication, wind rod, wind cross arm, sensor cross arm and other components. For example, how many watts of solar power are suitable to put PV plant in that place, how many watts of solar power are needed to be installed in a year, this kind of equipment is needed to help you make an assessment.

For solar photovoltaic power systems or solar application research, accurate measurements are of course of primary importance. The indicators to be monitored include, in addition to solar radiation, many environmental factors that have an impact, such as the basic supply of the system, ambient temperature, module temperature, wind speed, wind direction, light composition, and other meteorological parameters that have an impact on the light energy conversion products.
