Suntech Power Holdings Co. Ltd. says its solar modules have passed the official blowing-sand test based on DIN EN 60068-2-68 LC2 by SGS, an inspection, verification, testing and certification company. The SGS test result confirms that Suntech's solar modules are suitable for solar installations in desert regions.
‘As solar energy proliferates around the world, it is critical to develop solar modules that can perform optimally in different terrains and environments,’ says Stuart Wenham, Suntech's chief technology officer. The blowing-sand test is designed to confirm that solar modules can withstand high-velocity sand and wind conditions.
To determine the effects on solar panels of dust and sand suspended in air, the test 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 module. Suntech solar modules passed the maximum power determination, the insulation test and the wet leakage current test, the company says.
