Effects of Damp-Heat into Crystalline Silicon Photovoltaic Solar Modules in Benin (Tropical Area)

During their outdoor service, photovoltaic (PV) modules are exposed to different set of environmental conditions that can affect their performance such as Damp-Heat. But theses external conditions varied from one area to another. This work aims to highlight the impact of environmental conditions on the performance of crystalline silicon photovoltaic solar modules exposed in the tropical environment which is a hot and humid area. We have firstly studied the degradation of the solar photovoltaic module under the effect of moisture and the heat by using the analytical models of Erying, Peck and Laplace transformed. Then we have compared these models to the experimental Damp Heat model of Hulkoff. We finally verified the impact of the environmental conditions of the tropical environment on the photovoltaic modules by simulating their behavior over time under real conditions using the relative humidity and average temperature data of the synoptic stations of Benin. The theoretical results obtained, compared to those obtained by Hulkoff in experiments showed firstly a reduction of about 3% in the electrical performance of photovoltaic solar modules over period and a loss of performance of PV modules ranging from 0.19% to 0.5% per year. The PV module performance degradation rates over the study period correlate with those found in the literature on different systems installed in various regions of the world. So, future researches on crystalline silicon photovoltaic solar module can be effect of Damp-Heat on its electrical parameters in tropical area.
