Algeria <p align="justify">The objective of the developed system is to encourage efficient water management practices that optimize the usage of water by keeping crop health and yield intact through the implementation of an automated irrigation system. The study aimed to determine the impact of irrigation by fish farming on growth rates and concentrations of macro- and micronutrients in tomatoes. Results indicated that irrigation with fish farm effluent significantly increased and effluent water, depending on its composition to feed the fish, can supply nutrients and increase the concentrations of these elements in tomatoes irrigated with this water with a refractive index = 1.3391 and a calorie value of 19.927 Calorie in the first sampling and 16.696 calories in the second sampling for 100 g for the year 2021 and for the year 2022 we have a refractive index = 1.3495 and a calorie value of 20.66 Calorie for 100 g. Here we show for the first time that is more than the standard norm (Cotte.2000) which is 18 Calories. Also, after carrying out microbiological analyzes, there is a total absence of pathogenic bacteria, as well as the organoleptic parameters are heading in the right direction where tomatoes irrigated by fish farming water is concentrated compared to the tomatoes irrigated by normal fresh water with Light red of 53 %, Cooked acid of 47 %, spherical form of 94 % and a pleasant smell of 88 %. Therefore, using fish farm effluent in irrigation provides water requirements for plants and also can improve the availability of nutrient elements for tomatoes.</p> Malika Allali, Cherif Tigani, Abdelkrim Djaber, Ahmed Mediani Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000 Clear Sky Global Surface Solar Irradiance Estimation from Bird & Hulstrom Radiometric Model/MODIS Atmospheric Data Combination <p align="justify">Estimation of solar irradiance received on the ground is essential in many solar energy applications, particularly those relying on concentrating solar technologies. In this work, we propose a model to estimate the spatial distribution of global Surface Solar Irradiance (SSI) from a Bird &amp; Hulstrom radiometric model/MODIS atmospheric data combination. The theoretical model selected is the radiometric model of Bird &amp; Hulstrom, and it has been modified to take into account the effect of the atmosphere by adding a transmittance function that obeys the Beer-Lambert law, implemented with atmospheric parameters (water vapor, ozone, aerosols, etc.) from the Moderate Resolution Imaging Spectroradiometer (MODIS) atmospheric products. The effectiveness of the proposed methodology is tested on the Algerian territory. The obtained results show that the proposed approach concurs with results provided by the tested Meteosat data-based method while providing SSI maps of better spatial resolution. Moreover, the obtained solar irradiances show a root mean square error of about 140 Wh.m-2 in comparison with the Copernicus Atmosphere Monitoring Service (CAMS) radiation extracted from the Solar Radiation Database for the environment (SoDa) server.</p> Farah Benharrats, Habib Mahi Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000 Structural Characterization of ZnO Thin Films Deposited onto Silicon Substrates using Cathodic Magnetron Sputtering <p align="justify">In this study, we analyzed Zinc Oxide (ZnO) thin films deposited on silicon substrates using magnetron sputtering. These films have numerous applications in photovoltaic and optoelectronic devices due to their excellent physique properties. We used two structural characterization techniques: X-ray diffraction and scanning electron microscopy. We found that the ZnO films had good crystallinity and a columnar structure on the substrate surface, as indicated by the (002) orientation. These findings could potentially be useful for the development of ZnO-based devices such as solar cells and piezoelectric sensors. our results are consistent with those found by other researchers.</p> Leila Ghalmi, Souhila Bensmaine, Chems El Hayat Merzouk Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000 Energy Renovation of an Old University Building <p align="justify">Old buildings consume a lot of energy and no longer comply with thermalregulations, which creates interior discomfort. Our work consists ofhighlighting the effect of the rehabilitation of the building on energy savings and thermal comfort. The case study is an old building converted into offices.We made a dynamic thermal simulation under TRNSYS 17 to analyze thethermal and energetic behavior of the building. The results obtained afterinsulating the opaque walls and replacing the openings are very conclusive.Surface losses decreased by 72%, the heating power decreased by 67%, andthe air conditioning power decreased by 50%.</p> Razika Kharchi, Fetta Danane, Amel Ounnar, Abdenour Bourabaa, Amira Badjoudj Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000 Design of an autonomous photovoltaic power supply system for Nyabikenke Hospital (Burundi) using the ETAP tool <p align="justify">Our energy future must be based on non-polluting energies with significant resources. Renewable energies are the best candidates, but the intermittency of their production requires finding efficient and environmentally friendly storage means. Solar electricity must be stored to be used later when needed. There are many ways to store electricity, and they all involve converting it to another form of energy that is easier to contain. A study on the design of an autonomous electrical system was carried out at Nyabikenke Hospital to solve the major problem of the lack of hydroelectric power at Nyabikenke Hospital. We therefore first sought to estimate the energy needs of the user and then proceeded to an optimal dimensioning of our system using the ETAP software. In normal operation, the photovoltaic field and the battery bank will operate, in the event of a cut in the two sources, the emergency Diesel generator intervenes. The design tool simulates the operation of an autonomous electrical system for a load of 131.5kW necessary for the hospital to be supplied. He can design any system from the experimental results of the components. The results of the simulation make it possible to characterize the operation of the system in an autonomous application, determine its performance, and evaluate the influence of the various losses.</p> Joel Niyonzima, Jean Bosco Niyonzima Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000 Prediction of direct normal irradiation using a new empirical sunshine duration-based model <p>In this work, we are interested in presenting a new approach allowing us to express the Direct Normal solar Irradiation (DNI) according to the sunshine duration essentially. This choice is justified by the fact that in addition to the sunshine, duration has a strong correlation with solar irradiation, it is measured in many radiometric stations. Some clear sky models with modifications developed exclusively here are made valid for all types of sky. The proposed model is compared with one of the intelligent models such as the Support Vector Regression (SVR) for daily data from Ghardaïa.</p> Abdelatif Takilalte, Ali Dali, Mohammed Laissaoui, Amar Bouhallassa Copyright (c) 2023 Journal of Renewable Energies Wed, 04 Oct 2023 00:00:00 +0000
