The SGS Solar Test House, operated in Germany by SGS Germany GmbH, says it has added desert dust testing to its suite of services for solar modules.
The company tests modules to the DIN EN 60068-2-68 LC2 standard, which determines the effects of dust and sand – suspended in air – on solar modules. This desert dust test simulates the impact of high-velocity particles and proves the solar module's applicability for desert regions.
In order to determine the effects on solar panels of dust and sand suspended in air, the 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 module, the company explains.
