The Solarwatt modules have shown to be particularly suited for coastal and desert regions, where sandstorms are known to be frequent.
Extensive load tests form the basis of the test report produced in accordance with DIN standard 60068-2-68. The report is akin to those compiled for blowing dust tests done in automotive and aerospace industries.
The test modules from Solarwatt were placed in a specially equipped dust chamber for a few days. The test showed that the modules remained undamaged and the follow up inspection, according to IEC 61215, showed no abnormalities.
