| Abstract: |
| High Temperature and accumulation of dust on the photovoltaic panels in the natural outdoor environment is a critical problem which has a big effect on its performance. A number of studies show that the dust accumulation on PV panels can reduce the performance of the installed system. In this paper, the electrical performance is studied, represented in measuring several parameters of dusty and cooled PV compared by cleaned panels. The electrical performance measured parameters are, the short circuit current, the maximum current, the open voltage, the output power, and the weather parameters; solar radiation and the panel’s surface temperature. The objective of this research was to study the effects of high temperature and dust accumulation on different types of solar panels placed in natural outdoor conditions in Cairo. It was found from the study that the accumulation of dust on the surface of different types of solar panels can reduce efficiency by 30%. While the high temperature can reduce the efficiency of up to 10 %. |
