In our daily life, cookers are nealrly indispensable and very common to all of us. The evolution of cookers also has many changes from the most primary to the most modern and convenient ones. However, types of cookers like coal, oil or gas cookers have partly affected our environment with numerous toxic gas produced into the air.
To solve this problem, they have invented electric cookers, but the limited and expensive source of electricity also becomes another problem for the scientists. Therefore, the appearrance of the solar cooker with the permanent resource and a great benefit for the environment has marked a new era of technology in household appliance.




Heat-trap boxes, curved concentrators (parabolics) and panel cookers are the three most common types of solar cookers being used in numerous diverse kinds. Besides, several large-scale solar cooking systems have been developed to meet the needs of institutions worldwide.


1. Box cookers

Box cookers cook at moderate to high temperatures and often accommodate multiple pots. Worldwide, they are the most widespread. There are several hundred thousand in India alone.











2.Curved concentrator cookers

Curved concentrator cookers, or "parabolics," cook fast at high temperatures, but require frequent adjustment and supervision for safe operation. Several hundred thousand exist, mainly in China. They are especially useful for large-scale institutional cooking.

3.Panel cookers

Panel cookers incorporate elements of box and curved concentrator cookers. They are simple and relatively inexpensive to buy or produce. Solar Cookers International's "CooKit" is the most widely used combination cooker.
