Clear-sky irradiance (CSI) modeling constitutes an essential component of the evaluation of
the solar resource at any location, and is involved in a large number of applications. In solar …

The solar photovoltaic (PV) energy has an important place among the renewable energy
sources. Therefore, several researchers have been interested by its modelling and its …

This research work proposed a new model used to predict the direct, diffuse and global solar
flues for clear skies, by making the comparison between the numerical simulation of this …

Global demand for energy is increasing rapidly and natural energy resources such as oil,
gas and uranium are declining due to the widespread diffusion and development of the …

The study focuses on the evaluation of global solar radiation on a horizontal level. The
estimate of the solar layer was made on the basis of mathematical model obtained from the …

In this paper, a mathematical model is used to determine the solar radiation incident on an
inclined surface and the optimum slope angles for each month, season, and year are …

Due to several climate changes caused by greenhouse gas and to the increasing need for
clean energies, scientists drew attention to renewable energy sources, which are the most …

The present work aims to determine the empirical model R. sun that will allow us to evaluate
the solar radiation flues on a horizontal plane and in clear-sky on the located Adrar city (27 …

In this paper, we study the effect of temperature and external solar flow on the evolution of
daily solar radiation incidental on the walls of a building located in the ADARAR region of …

Chad is like many African countries with no meteorological station at the moment to measure
solar radiation throughout the country. Thus, theoretical models are used to estimate …
