Why Do Solar Power Plants Need Weather Monitoring Station (WMS)?

It is very important to understand that a WMS cannot help you change the weather parameters, but it helps you to analyze and predict them so as to get maximum output from your solar plant.  


Photovoltaic (PV) system performance depends on both the quality of the system and the weather.  As the weather varies, the output of the PV system changes.  The key factor affecting the PV system performance is the solar radiation data.  But along with solar radiation data, the weather parameters like ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and rain are the other important factors affecting the performance.  The air temperature, relative humidity, and module temperature have a significant influence on the efficiency of solar modules.  The performance of solar modules is temperature-dependent.  Module temperature gives an indication of a change in the efficiency of the modules.  If the module surface temperature rises beyond the specified limit of the manufacturer, the efficiency of the panels will be reduced.  This will give the poor generation and will affect the plant performance.  


Data about amount and frequency of precipitation (rainfall) can help to explain low energy yields at high solar radiation.  If we can accurately measure the total useable incident radiation under any environmental conditions then, we will be able to calculate if the PV system is generating electricity as per the expectations.  The data of all these sensors can be used to schedule the maintenance of the plant.
