Innovative electric heating system for a hybrid solar cooker (photovoltaic/thermal) using photovoltaic energy with battery storage

In this paper we present the structure and operation of an electric heating system, using energy supplied by photovoltaic panels with storage in batteries, for a hybrid solar cooker (600 Wp). This innovative cooker is a sustainable alternative to domestic cooking and helps reduce dependence on fossil fuels. The system uses a 300 Wp photovoltaic panel and 24 V/180Ah batteries to heat by heating resistance, via a boost-type DC/DC converter (power block) controlled by a local and remote regulation (control and regulation block). Typical testing of the complete system over sunny days by photovoltaic panels, and batteries during night periods and lack of sun, showed stable operation at around 225–250 W, a DC/DC converter efficiency of 90% and heating temperatures of 350–400 °C. All the results obtained respect the needs of inhabitants and the specifications of the projects undertaken during this work. As a result, the use of this innovative solar cooker in rural and urban homes.
