A solar cooker is a type of solar thermal collector. It “gathers” and traps the Sun’s thermal (heat) energy. Heat is produced when high frequency light (visible and ultraviolet) is converted into low frequency infrared radiation.

What is the difference between a solar cooker and a solar oven?

Solar ovens are insulated boxes that capture heat from the sun and use it to cook food. Solar cookers generally have an open design; they are made up of reflective panels that direct sunlight and heat towards the center, where you can place a pot or pan.
