Abstract
One third of the planet’s landmass is covered by desert, which receives intensive solar radiation every day. Several experts studies have estimated that using just 4% of the total desert area for solar PV systems is sufficient to supply all the electrical energy requirements of the world. Outdoor installed inverters are subjected to extreme temperature fluctuations and problematic sand and dust in the air. The stress imposed by sandstorms can be especially severe, as the very fine dust can penetrate even the smallest openings, potentially causing problems within the interior of the inverter, the key component in any PV system. This fine sand and dust settling on an inverter’s sensitive electronics represents an enormous potential risk to the operation and longevity of the entire PV plant. In our paper, PV system application performances in extreme environments like desert conditions are analyzed and environment tests were studied to protect any possible harmful effects. Therefore we examine the test methods and evaluation criteria of safety test based on IEC 62109 standardization for safety evaluation and standardization of solar inverter applied to desert type and special environment.
