WSE-A60 PV Dust Measuring Instrument
Dirt, dust and organic/inorganic pollutants on PV modules lead to significant economic losses. WSE-A60 is a novel optical sensor that estimates PV glass fouling rate based on its optical characteristics. With no moving parts and minimal maintenance, it approximates the actual fouling rate of PV arrays by measuring dirt’s impact—assuming consistent pollution between arrays and the sensor surface (per IEC61724-1:2021).
