Structural and physicochemical properties of dust collected on PV panels surfaces and their potential influence on these solar modules efficiency in Dakar, Senegal, West Africa
Mamadou Simina Drame, Dialo Diop, Kharouna Talla, Moussa Diallo, Balla Diop Ngom, Bado NebonTwo dust samples were collected from the same solar panels on June, 2017 in Dakar. The first was sent to Ithemba Labs (South Africa) and the second to Lincon Nebraska University (USA) for structural and physical properties study. This work aims to evaluate the dust impact on PV efficiency. The...

Experimental Study of an Indirect Solar Dryer Using a New Collector System. Application to Mango and Ginger Drying
Thierry Sikoudouin Maurice Ky, Damus Abdoul Aziz Traore, Bienvenu Magloire Pakouzou, Boureima Dianda, Emmanuel Ouedraogo and Dieudonne Joseph BathieboIn this paper, an indirect solar dryer using a new type of collector is studied. The collector is built with hemispherical concentrators with an axially-centered Fresnel lens placed on top of each. That allows the collector's aperture area of 0.32m2 to fully contribute to the hot spot generated...
