In this paper Artificial Neural Network (ANN) is used to predict the solar irradiation in Djibouti for the first Time that is useful to the integration of Concentrating Solar Power (CSP) and sites selections for new or future solar plants as part of solar energy development. An ANN algorithm was developed to establish a forward/reverse correspondence between the latitude, longitude, altitude an...

consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

maximum power point tracking controller is essential to obtain the maximum power from a solar array in the photovoltaic systems as the pv power module varies with the temperature and solar irradiation. in this paper, several methods for the mppt of the pv systems are discussed and it can to be used as a helpful reference for the upcoming mppt user in the pv applications.

background: tremendous amount of researches have investigated the issue of water photodisnfection. the aim of this research is to illustrate the influences of bacterial density, turbidity, exposure time and potassium persulfate (kps) dosage on the efficacy of associated solar disinfection (sodis) with kps for e. coli (atcc: 25922) eradication as an efficient and inexpensive process. methods: de...

A methodology for downscaling solar irradiation from satellite-derived databases is described using R software. Different packages such as raster, parallel, solaR, gstat, sp and rasterVis are considered in this study for improving solar resource estimation in areas with complex topography, in which downscaling is a very useful tool for reducing inherent deviations in satellite-derived irradiati...

The paper reports on the effects of a proton irradiation campaign on a series of thin-film silicon solar cells (singleand double-junction). The effect of subsequent thermal annealing on solar cells degraded by proton irradiation is investigated. A low-temperature annealing behaviour can be observed (at temperatures around 100 to 160 C) for microcrystalline silicon solar cells. To further explor...

The air-conditioning energy consumption, for cooling or heating, has currently a growing trend. The purpose of this work is to develop a method suitable to design optimal threedimensional building forms to reduce air-conditioning needs in a chosen location by using weather data. The method exploits in particular both diffuse and direct solar radiation; not independently but rather in relation w...

In order to obtain the best performance of the solar air heaters, it is necessary to find optimum performance conditions. The aim of this research paper is to achieve optimum conditions, by comparing single and double pass solar air heaters. Also, a brief review study of various related research works of all scenarios for a single and double pass and packed bed (including particle technologies)...
