Yingli solar modules pass Blowing Sand Test for desert conditions

By Editor


Greentech Lead Asia: Yingli Green Energy announced the company’s PV modules have passed the Blowing Sand Test conducted in SGS’s Solar Test House, demonstrating that its PV modules can keep an outstanding performance even in harsh conditions such as in the desert.

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.

SGS 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.

In a similar announcement recently ReneSola announced that the company’s PV modules have been certified by TUV Nord, a leading German industry-certification body. The TUV Nord certification reaffirms that the modules can withstand dusty and desert-like conditions in regions like the Middle East.
