Experimental study on the impact of soiling on the modules temperature and performance of two different PV technologies under hot arid climate.

In this paper we conducted an experimental study to evaluate the impact of soiling on the temperature and electricity production of two photovoltaic technologies (Poly-Si and CdTe) under a hot semi-arid climate of Morocco. For this purpose, two modules -from each technology-were exposed for one year where one is cleaned every day and the other is left to accumulate soiling on its surface. In parallel, the electrical parameters, the weather data and the modules temperature were monitored using high precision instruments.

Degradation and performance analysis of a monocrystalline PV system without EVA encapsulating in semi-arid climate.

The objective of the current paper is to evaluate the performances drop of a photovoltaic system composed of a new PV module conception without EVA encapsulation. After three years of operation under harsh atmospheric condition at Green Energy Park research facility, in the mid-south of Morocco, the system shows an energy drop around 1.8kWhe in one of its strings.
