The Solar Cooker Box Is Covered With A Glass Sheet

The box of a solar cooker is covered with covered with a glass plate because the glass traps the heat and does not allow to escape.

The solar cooker box is covered with a glass sheet.

This glass sheet covers does not allow the solar energy to flow out in the form of radiant heat thus it traps more and more heat rays of the sun as it is exposed to sun. The reason for this is so that your solar box oven will be able to retainthe heat that builds up from the reflector panel concentration of the suns rays onto your dark cooking pot as well as into your box cooker interior. This cooker is preferable to a parabolic if small children are around. When sunlight falls over the solar cooker the sun rays passes through the glass sheet and get absorbed inside the cooker box.

Yes that is correct as the site instructed you on placing a plastic or glass cover on your solar box cooker. Box is covered by two layers of transparent glass keeping a gap in between and the supporting frame of the cover is hinged with cooker box for keeping glass cover in inclined position to handle the cooking pots. Box solar cookers have an insulated box topped with a transparent glass or plastic cover and a reflector or reflectors that help heat the box.

Somewhat limited in cooking abilities but extremely portable sport solar cooker for camping and outdoor cooking. This glass sheet covers does not allow the solar energy to flow out in the form of radiant heat thus it traps more and more heat rays of the sun thereby producing green house effect that is why glass lid is used in the solar cooker. This helps to increase the temperature inside the box and the food is able to cook faster. In a solar cooker the glass sheet prevents the thermal radiation of the sun light from going out of the box causing green house effect.

So it creates a greenhouse effect. When sunlight falls over the solar cooker top the sun rays pass through the glass sheet cover and get absorbed inside the cooker box. Temperatures inside the box can reach 400 degrees f and cooking can be done almost unattended like a slow cooker.
