In order to check the performance of a photovoltaic system, at least two parameters are always recommended – on the one hand the parameter that the system itself emits and another for testing. This is the only way to really ensure that your solar system is working efficiently. If you only rely on the power output of the solar system, you may discover any performance impairments such as dirt or defects too late.
This is where the pyranometer comes into play: The pyranometer measures the total solar radiation. This results in a characteristic curve that provides information about this global radiation.
If this characteristic curve deviates from the characteristic curve of the photovoltaic system, this is an indication of a possible defect in the system.
KNX pyranometers offer a decisive advantage at this point: you can set the corresponding limit value in the KNX system. If this is exceeded, you will receive an alarm via the system.
