Yingli Green Energy Holding Co. Ltd. says its PV modules have passed the blowing sand test conducted by Geneva-based SGS. The testing center's Solar Test House simulates the erosion effects of high-velocity sand particles within dust chambers.
‘Endurance testing like blowing sand test is critical to understand the reliability and durability of PV modules in real-world conditions,’ says SGS Technical Manager Daniel Deng. ‘SGS follows an internally developed test procedure and can customize specifications like sand homogeneity, sand concentration, sand shape and wind speed according to [specific] deserts.’
