DEVELOPMENT OF AN INNOVATIVE COOKER (HOT PLATE) WITH PHOTOVOLTAIC SOLAR ENERGY

In this paper, we present the feasibility of an innovative autonomous solar cooker (hot plate) running on renewable photovoltaic (PV) energy. The proposed equipment is based on the sizing, design and construction of a PV system, adapted to the needs of users in the rural and especially urban world. It is formed by PV panels, DC / DC energy converters, thermal resistors and a digital block for control, supervision, acquisition and displays of meteorological, thermal and electrical quantities of the system (lighting, PWM signals, currents, voltages, powers, efficiency, temperatures, etc.). Experimentation with the system for whole days shows, for an intensity of illumination varying from 400 W/m(2) to 900 W/m(2) and an ambient temperature of the order of 22 degrees C, the overall electrical power supplied by the panels PV of 430 W/peak, and the temperature of the thermal resistance, reaches after 15 s, the value of 580 degrees C (i.e. 38.66 degrees C/s). Under these conditions, the boiling of one liter of water and the cooking of 2 Kg of food (fries) took place after 25 minutes of cooker operation. Comparison with conventional thermal cookers shows a marked improvement in the cooking temperature, boiling times and heating speed of 178% (a factor of 2.79), 83.3% and 943% (a factor of 10.43) respectively. In addition, the thermal efficiency of the cooker is estimated at 86%, an improvement of 59.2% compared to conventional cookers. All the results obtained clearly show remarkable performances, consequently the feasibility of the innovative photovoltaic cooker, proposed during this work, inside and outside the homes.

Automated summary

This paper presents the feasibility of an innovative autonomous solar cooker running on renewable photovoltaic energy. Through experimentation, the cooker showed improved cooking temperature, boiling times, and heating speed compared to conventional thermal cookers. The results suggest remarkable performance and potential for the innovative photovoltaic cooker in both indoor and outdoor settings.
