Types of Solar Cookers ,

• Box Solar Cooker :

They are made in both circular and rectangular shapes. They consist of an enclosed inner box covered with clear glass or plastic, a reflector, and insulation. There is a wide variety of patterns and plans for the box cooker. While they do not heat quickly, they do provide slow, even cooking and are extremely cheap to make. Box cookers are very easy and safe to use, and fairly easy

• Panel Solar Cooker :

Panel cookers are flat reflective panels which focus the sunlight onto a cooking vessel without the inner box common in box cookers. Panel cookers are the easiest and least costly to make, requiring just four reflective panels and a cooking vessel, but they are unstable in high winds and do not retain as much heat when the sun is hidden behind clouds. The diagram shows a panel cooker with a dark cooking vessel and thermometer all wrapped in a plastic oven bag.

• Parabolic Solar Cooker :

Parabolic cookers require more precision to focus the sunlight on the cooking vessel and are therefore the most complex design to build. If the sunlight is not focused exactly on the cooking vessel, the food will not cook efficiently.
