Comparative study of heat storage and transfer system for solar cooking

To run the Solar energy appliances, the continuous availability of solar energy is an essential. The Solar appliances are run by using solar energy either from PV cell or solar collector. Both of these devices require continuous solar rays. In order to use the solar energy after sunshine, it requires being stored first and then can be transferred to the appliances. One of the focused applications by using solar energy is the solar cooking. A Lot of research is going on the use of solar energy for cooking. But still, some extensive technique needs develop for easily usable systems. The various solar cookers are discussed to insist the need for development of solar storage systems for efficient cooking. This paper presents the comparative study of heat storage and transfer systems for solar cooking. The key aspects like, methodology to develop the heat storage system, requirements and properties of heat storage materials, need of insulations and their types are addressed. Some most usable materials are also analyzed.
