A new concept of building integrated solar water collector and the experimentation are described, then experimental results are shown. Numerical calculations are performed in Matlab environment using a finite difference model and an electrical analogy.

Calculating global solar irradiation from global horizontal irradiation only is a difficult task, especially when the time step is small and the data are not averaged. We used an Artificial Neural Network (ANN) to realize this conversion. The ANN is optimized and tested on the basis of five...

A new concept of flat plate solar collector is presented: its originality comes from its remarkable shape and from its integration into a rainwater gutter. The complete solar collector consists in several short modules connected serially. After a brief presentation of the building energy...

It is essential to find solar predictive methods to massively insert renewable energies on the electrical distribution grid. The goal of this study is to find the best methodology allowing predicting with high accuracy the hourly global radiation. The knowledge of this quantity is essential for...

Nowadays, energy supply is a major challenge for developing countries. In Sub-Saharan Africa, about only one-third of the population is connected to the electrical network and the use of classical energy resources presents economical and environmental problems. As many other African countries,...

Electric vehicles (EVs) are on the verge of breaking through, most presumably flooding the automotive market with lithium-ion batteries as energy storage systems. This paper investigates the availability of world lithium resources and draws conclusions on its actual impact on the EV industry....
