Feasibility of a Box-type Solar Cooker Powered by Photovoltaic Energy

Abstract

In this paper, we have realized and experimented a box-type solar cooker that is powered by photovoltaic energy. Under an illumination of 770 W / m2, an ambient temperature of 18°C and electrical power of 340 W, the results show, on the one hand, a temperature of the thermal resistance which heats the cooker equal to 686°C, and, on the other hand, a temperature and a thermal efficiency of the cooker worth 200°C and 77%, respectively. Heating one liter of water yields a boiling time of 50 minutes, and the time needing for complete evaporation is of the order of 3 hours. In addition, the results show very significant improvements compared to thermal cookers operating directly to the sun, namely 53% increase of the heating temperature and 60 % decrease on its heating duration. All the results and performances obtained in this work demonstrate the feasibility of box-type solar cookers, powered by photovoltaic energy inside homes.
