Weather Monitoring System for Solar PV Power plants

IEC61724-1:2021 complaint Weather Monitoring Station.

The energy generation from Solar PV power plants is dependent on various atmospheric conditions. It is thus very crucial to have an accurate and reliable Weather Monitoring Station (WMS). A Weather Monitoring Station (WMS) plays a crucial role in the performance monitoring of Solar Photovoltaic (PV) Plants by providing real-time and historical meteorological data. This information is essential for optimizing the efficiency and output of solar power systems.


Aeron’s Weather Monitoring Station (WMS) complies to the guidelines outlined in IEC 61724-1:2021. The WMS is a perfect product for real-time, accurate and reliable monitoring of environmental conditions, thereby keeping track of plant efficiency and maintenance of solar power sytems on a real-time basis.
