To determine the effects on solar panels of dust and sand in air, SGS's Solar Test House simulates the erosion effects of high-velocity sand particles within dust chambers. Pulses of compressed air are blown through a manifold located in the bottom of a collection trough, forcing dust up and over the solar modules. The Test contains maximum power determination, the insulation test, and the wet leakage current test.

"We're pleased to see our modules passed SGS's Blowing Sand Test," said Dr. Dengyuan Song, Chief Technology Officer of Yingli Green Energy. "This test result once again proved the high quality of our products attributable to our continuous optimization of our manufacturing technologies and unwavering commitment to high quality. We believe the test result will help further reinforce our customers' confidence in the "Yingli Solar" brand and our position as an industry leader."

Dr. Daniel Deng, Technical Manager for SGS said, "Endurance testing like blowing sand test is critical to understand the reliability and durability of PV modules in real world conditions. SGS follows an internally developed test procedure and can customize specifications like sand homogeneity, sand concentration, sand shape, and wind speed according to single selected deserts. Test result of Yingli's products has showed the lowest power degradation after long term blowing sand testing among all our customers of Si-crystal modules till now. We were extremely impressed with the quality and performance of Yingli's PV modules to withstand the blowing sand test that replicates the conditions of real world's desert sandstorm."
