This work refers to a process of purification of silica sand and, more particularly, to a process of iron and aluminium removal from the Algerian silica sand particles. Iron compounds are among the most difficult impurities to release from the sand particles. Several methods to remove iron from the sand particles are used; in our work we employed the acid leaching process as optimal solution to purify the silica sand. To this purpose, our work began by characterization of sand samples using X-ray fluorescence, for measurement of concentrations of major mineral oxides, and using atomic absorption, to determine the iron and aluminium concentrations in the silica sand particles. Through this study, the samples were enriched by acid leaching method, by removing the impurities from the crystal lattice, as well as from its surface. Thus reduction the impurities concentration increases, at the same time, the SiO2 concentration. The obtained enriched silica can be used as raw material for silicon production, destined for photovoltaic application.

This paper presents an evaluation of the performance degradation of photovoltaic modules after twelve operation years in a steppe region environment in Algeria. The objective is to understand the different degradation modes of the photovoltaic modules and associated factors and their impact on the electrical properties (Voc, Isc, Vmax, Imax, Pmax and FF) using the degradation tests of IEC 61215 qualification standard and the electroluminescence test. The experimental results show that yearly degradation rates of the maximum power output Pmax present the highest possible loss, ranging from 2.08% to 5.2%. Additionally, the results show that the short-circuit current Isc comes second with yearly degradation rates spanning from 2.75% to 2.84%. Finally the open-circuit voltage Voc is the least affected, with yearly degradation occurring from 0.01% to 4.25%.

“…Solar cells are photovoltaic (PV) devices, converting the Sun energy directly into the electrical energy. The current and voltage, provided by the smallest structure unit of a PV system are very small [2]. To get a usable energy, in a PV panel, a lot of solar cells must be connected in series or in parallel with each other.…”

Today, the use of renewable energy resources is increasing rapidly because the solar energy is easily accessible and abundant. Solar energy is converted into electrical energy using photovoltaic panels. Photovoltaic panel is an energy source, which contains many solar cells, absorbing the solar energy. Factors affecting the operation of photovoltaic panels are the solar irradiance, the temperature, the surface, and the direction angle. For this reason, before employing a photovoltaic panel, the power values, which can be obtained from such photovoltaic panel should be analyzed and evaluated according to the application conditions, considering all these factors. In this study, calculation of power, current and voltage, generated by a photovoltaic panel, was performed on a mobile device for a determined region. Hourly, daily and monthly total power information, obtained according to the characteristics of the photovoltaic panel, such as panel position, direction and inclination, that can be obtained using the mobile device, are presented to the user by the developed application.
