| Popis: | 8th World Conference on Photovoltaic Energy Conversion; 777-779 PV modules in desert climate are exposed to environmental stressors cycles such as elevated temperature, UV radiation, sand abrasion and large temperature fluctuations, which can degrade different components of the module and eventually lead to defects. These defects and degradations reduce the power output of the system, as well as the lifetime of PV modules, affecting system reliability. The performance and soiling degradation of 5 different types of PV modules installed in 5 different tilt angles for 5 years in desert condition of Dubai have been reported. NREL RdTools has been used to extract the degradation and soiling rate of all the PV modules. The results from the 5×5 heat map matrix of modules show that the highest degradation and soiling is for the modules installed at 0° angle. The average degradation rates in the desert environment are found to be much higher than the industry average reported values of 0.7%/ year for most commercial PV modules. |
