Solar energy technologies are
upgrading day by day in every sunshine-rich region around the globe. These
technologies provide a strong platform for humans for high-demand activities
like cooking, air heating, power generation, etc. Among these activities,
solar cooking is much popular due to daily cooking needs. Different designs of
solar cookers are available in the market according to the family size. In the
present work, the designs of some commonly used solar cookers and their thermal
performance evaluation have been discussed. Heat transfer analysis shows that cookers
with some potential heat storage materials are better than conventional solar cookers.
The design of such cookers is feasible to cook efficiently for long hours, even
during off sunshine hours (for a limited period).
