PV standalone systems are challenged by the PV intermittent nature, hence integrating
energy storage systems (ESS) is mandatory. In this paper a hybrid battery/supercapacitor …

This study examines the large amount of agricultural waste produced in Egypt between
2010 and 2019 by analysing data from various departments within the Agriculture Ministry. It …

[en] The performance of a flat plate solar collector with thin absorber is studied. The
temperature of the absorber and its variation along the local day time is obtained by solving …

A simple formula to predict the received global solar irradiance q (t), W/m2 for clear days is
suggested on pure theoretical basis. It is expressed in terms of the length of the local day …

Flat plate collector with thin absorber is studied. Heat balance equation is solved to estimate
the temperature of the absorber and its variation along the local day time. The same …

The prediction of the global solar radiation through a distribution function q (t), W/m2 for
clear days is given where" t" is the local day time.: The distribution is based on a simple …

Human health and prosperity are threatened by the high levels of pollution resulting from the
use of conventional fossil fuels (coal, gas, oil and its products) for energy generation …
