Development of double burner smart electric stove powered by solar photovoltaic energy

摘要

Bangladesh is facing overwhelming energy challenges that are likely to increase over the next few decades. By acknowledging the potential of renewable energy technologies and associated energy storage, Bangladesh could possibly meet its unprecedented energy demand. Our goal is to design a project which involves the development of a solar-powered electric stove that would use sunlight as a source of power. The electricity and gas shortage in Bangladesh are strong motivators for a solar electric stove to replace the normal stoves. Our system consists of two burners which altogether require solar panels providing power of 1520W. The coils were designed according to the power rating. There are two sets of 48V lead acid batteries which share the power with the Photovoltaic panels while cooking in daylight; the batteries are charged by the panels when the stove is not in use. Heat controllers have been mounted to allow the user to regulate the heat. Moreover, food had been cooked on the designed stove and data obtained has been analyzed. Satisfactory results in terms of the cooking time of various food has rendered us to conclude its effectiveness for the households in distant rural areas of the country.
