With increasing numbers of PV power plants expected to be located in harsh conditions such as in the desert’s, leading PV module manufacturer and PVEP, Yingli Green Energy said its modules had passed the Blowing Sand Test, conducted by SGS.

Air transported dust and sand granules, especially at high-velocity can damage PV modules, reducing life-times and accelerate performance degradation.

Conducted at an SGS test house, Yingli Green’s modules were experienced to 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 was said to contain maximum power determination, the insulation test, and the wet leakage current test.

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.”
