Solar oven or solar cooker is a cooking device that uses sunlight as an energy source. Since this type of stove does not use conventional fuel and operating costs are low, a humanitarian organization to promote its use throughout the world to reduce deforestation and desertification, caused by the use of wood as fuel for cooking.
Solar cookers can be used outdoors, especially in situations where minimal fuel consumption or fire risk becomes an important consideration.
The working principle
There are different types of solar cookers. Everything uses heat and light from the sun to cook food. Some basic principles of solar cookers are as follows:
Heating of a good strategy by using solar energy becomes less effective if only using one of the principles mentioned above. In general, solar cookers using at least two ways, or even third basic principle of solar cookers to produce a sufficient temperature to cook.
Apart from the need for sunlight and needs to place the solar cooker in the right position before use, the stove is not much different from the conventional stove. However, one disadvantage is that solar cookers are generally ripen food on a hot day, when people tend to be reluctant to eat hot food. However, the use of thick, slow pans conduct heat (like a pot of cast iron / cast) can reduce the speed of heat loss and by combining it with the use of insulating hot stove can keep food warm until the evening.
Stove cover can usually be opened to put the pan into it. Box cookers generally have one or more reflective than the material of aluminum foil or other reflective material to reflect more light into the interior of the box. Pressure cookers and parts in the bottom of the cooker should be dark or black. Inner walls of the stove should be able to reflect light to reduce heat loss and direct reflected light toward the pot and stove, dark basic, direct contact with the pan.

The working principle
There are different types of solar cookers. Everything uses heat and light from the sun to cook food. Some basic principles of solar cookers are as follows:
- Concentration of sunlight. Some devices, usually a mirror or some sort of metal / metal that reflect light, are used to concentrate the sun's light and heat toward the cooking area is small, making the energy more concentrated and more potential to generate enough heat to cook.
- Convert light into heat. The interior of the solar cookers and pans, of any material from the black, can increase the effectiveness of turning light into heat. Black pot can absorb almost all the sunlight and convert it into heat, substantially improving the effectiveness of solar cookers. The better ability to dissipate heat the pan, the faster the stove and oven work.
- Trapping heat. Efforts to isolate the air inside the cooker from the air outside it would be important. The use of materials such as hard and clear plastic bag or cover the pan made of glass allow light to enter into the pot. Once the light is absorbed and turned into heat, plastic bag or cover made of glass will trap the heat in it like the greenhouse effect. This allows the stove to reach the same temperature when it was cold and windy as well as sunny and hot day.
