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. Â
Photovoltaic (PV) system performance depends on both the quality of the system and the weather. Â As the weather varies, the output of the PV system changes. Â The key factor affecting the PV system performance is the solar radiation data. Â 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. Â The air temperature, relative humidity, and module temperature have a significant influence on the efficiency of solar modules. Â The performance of solar modules is temperature-dependent. Â Module temperature gives an indication of a change in the efficiency of the modules. Â If the module surface temperature rises beyond the specified limit of the manufacturer, the efficiency of the panels will be reduced. Â This will give the poor generation and will affect the plant performance. Â
Data about amount and frequency of precipitation (rainfall) can help to explain low energy yields at high solar radiation. Â 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. Â The data of all these sensors can be used to schedule the maintenance of the plant.
