Feasibility of a Solar Heating Plate With Photovoltaic Energy

This paper concerns the feasibility of a photovoltaic (PV) heating plate. More particularly, by using a thermal resistance, heating of the water and cooking at temperatures above 200°C are analyzed during a sunny day. Through a system of acquisition of electrical and thermal measurements, the cooker set up provides for an illumination of 730 $W/m^{2}$ and peak power of the PV panels of the order of 230 W: heating temperature of the resistance 500°C after 30 seconds, variation of the heating temperature of water and oil 10 °C/\min$, bake temperatures above 200°C, and a thermal efficiency greater than 70%. The comparison of these results compared to the best published on conventional solar ovens of the box type, shows very interesting performance: improved temperature rise of 75%, improved cooking temperatures of 164% and thermal efficiency of 16%.
