The impact of some environmental variables on the performance of solar PV module

Abstract

The country of Iraq tops the list of countries in solar activity and therefore has the most important renewable energy sources, which we desperately need to fill the acute shortage of electrical energy. The availability of this source coincides with a significant rise in temperature in most of its regions and a wide range of days of the year. Where temperatures play a key role in wind activity and the provocation of dust storms, which urgently requires a field study to find out the impact of these factors on the performance of photovoltaic solar modules. Therefore, this study aimed to evaluate the performance of the solar module under the influence of dust accumulation, temperature and wind speed. A group symmetric of monocrystalline silicon solar modules have been experimented to see how these factors affect the performance of the modules. The results showed that there is a clear impact by the heat factor and dust accumulation on the performance of solar modules, but the wind factor is the least influential and what can be concluded is that Iraq, especially the city of Baghdad, is an ideal place to invest solar energy in the production of electrical energy.
