Use of Solar Power for Heat Generation for Household Application

The requirement of getting continuous electricity at low cost is essential but challenging. Especially in the undeveloped countries there is no sufficient electricity for the people to do their daily regular works. In order to overcome this problem different renewable energy sources are sought and being explored. One of the approaches is to have a cooking system that is energized from the solar power, not directly using a solar cooker but by storing the energy in the form of heat that can be utilized as per requirement. This paper reports the design and fabrication of an alternative system to generate heat using solar radiation. This chulha is helpful in effective heating with the help of solar radiations at lower costs. A cooking technology is presented consisting of a solar panel directly connected to an electric heater inside of a well-insulated chamber. An insulated container with fixed amount of oil is heated up. The heat is found to be retained in the chamber even after sun set which is sufficient for heating water for making tea. The possible causes of temperature drop and possible remedy has been pointed out and discussed in this paper.
