The tendency to exploit solar energy in the electricity production in Algeria is a priority and a major goal of the Algerian government, and for this reason it seeks to provide all the necessary capabilities to achieve this lofty goal. Photovoltaic electricity is one of the effective technologies for the solar electricity production, but before installing any photovoltaic panel, it is important to determine its optimal tilt angle, and based on this, this study allowed to show the optimal tilt angle of the photovoltaic panels in the Algerian region of El Oued in the spring season, and accordingly, two days (March 21st, 2023, and April 21st, 2023) were chosen to conduct this experimental study. Based on the obtained results, the optimal PV tilt angle for the month of March is 33° and 28° for the month of April. In addition, the greater the amount of solar radiation, the higher the efficiency and productivity of the PV panels, as the highest values for them (6.31 % and 62.17 W, respectively) were recorded on April 21st, 2023. The results of this study will contribute to the correct installation of photovoltaic panels in the Algerian region of El-Oued, especially if the photovoltaic panels are equipped with dual-axis solar tracking systems
A parabolic trough solar collector as a solar system for heating water: a study based on numerical simulation
(جامعة الوادي - university of el oued, 2017-12-25) Ghodbane, Mokhtar; Boumeddane, Boussad
This paper is an optical and thermal study of a small model of a parabolic trough solar collector (CTP), which will be used to heat tap water, in the winter, at Guemar location, (El-Oued, Algeria). A mathematical model was presented based on the energy balance equation applied to the absorber tube; this model was solved by the finite difference method. A computer program based on MATLAB was developed to solve the problem. The results show that the thermal efficiency of the concentrator can attend a high value of more than 61%, while the fluid outlet temperature can reach 343 K.

For proper comprehend the comportment and to define the parameters of a solar-driven ejector air conditioning system at low or medium temperature; a dynamic model depends on the principles of conservation, the momentum mass and energy is developed. For this purpose, the thermodynamic characteristics of the liquid and vapor refrigerant were identified using the Engineering Equation Solver EES software. Linear Fresnel Reflector (LFR) has been used as a tool to convert solar energy into thermal energy. The water (R718) was used as a refrigerant. The performance of the ejector air conditioning system was compared as a function of the operating parameters of the subsystem. The thermal efficiency of the Fresnel linear concentrator was as high as 31.514 %, and the overall thermal performance of the machine (STR) was as high as 20.764 %. The results obtained during this study are very encouraging. This technique can be used for air conditioning in desert areas in southern Algeria, where fossil energy (petroleum, gas, etc.) is extracted and produced in various types.
