In this work, we present a two-dimensional study of natural convection in a square air-filled cavity whose two vertical sides are subjected to a temperature difference, while the other two horizontal ones are adiabatic. The numerical method used is that of finite elements used in...

The evaluation of the solar deposit is essential for the sizing of photovoltaic systems. This requires the availability of radiation data. In Burkina Faso, weather data doesn’t cover all the country. That makes that solar radiation measured are not available for the all country....

Based on experimental results, we have demonstrated the ability of supercapacitors to provide the power needed to initiate the start-up of a pump during low solar irradiation. The objective of this study is to optimize solar pumping over the sun by compensating for power variabil...
