What is solar cooker?
The usage of solar cookers is very old. It was one of the first applications of harnessing and using solar energy. In ancient times, a Jewish sect called the Essenes used to cook food on rocks, heated by solar energy. From that concept, Horace de Saussure built a box-type solar cooker in 1776. This cooker was able to reach temperatures of about 190 degrees celsius. Then came the parabolic-style solar cooker built-in 1869 by Mouchot. French Colonial troops of Napoleon Three, used it in Africa. It was even displayed in an exhibition in Paris by cooking in twenty minutes. Later on in India, W. Adams developed a panel-style solar cooker to cook meat and vegetables. These were the three basic types that were made hundreds of years ago.
What is solar parabolic cooker?
Solar parabolic cookers usually have a disk around them, which is concave and focuses the sun’s rays. These cookers can reach a higher temperature than the solar box cooker or solar panel style cooker. These cookers can be used for normal cooking as well as grilling and frying. However, for efficiency and proper working of the cooker, its disk needs to be kept adjusted at all times. This is because the sun’s position in the sky changes every hour. The disk also has to be adjusted according to the temperature required at various phases of cooking. So a more experienced person can handle it. The capacity of this cooker is much less than that of a solar box cooker or panel-style cooker. This is because the size of the cooking pot is small. The solar parabolic cookers have a complicated construction and have a complex design. Many technicalities need to be maintained. Hence, these cookers are usually of higher quality and more expensive than the other two types.
Why are solar cookers black?
Therefore, most solar cookers are coloured black so that they can absorb more heat to cook well. Also, these cookers are thin so that the heat gets transferred quickly and uniformly to the food. The solar cooker should be able to trap the heat which it has absorbed. Otherwise, the heat will escape from the food.

What color is the best for solar cooking?
Absorption of the sun's energy (heat)in solar cooking is best achieved when a surface is dark in color, thus the most common solar oven interiors are usually black in color as well as the color of the cookware used for cooking the food. Dark colors absorb the heat, whereas light colors do not absorb heat well.
What is the final principle of solar cooking?
Retention is the final principle in solar cooking.If a solar cooker is not well insulated and if it does not have a cover, or lid, then all of the concentrated heat (energy) and all of the absorbed heat would quickly dissipate into the air and be lost to the surrounding environment.
What is the best cookware for solar cooking?
Generally, the best cookware for solar cooking is the dark, thin variety because it absorbs the heat (energy) well; and because it is thin, it can then transfer the heat more quickly and evenly to the food.
How often should you adjust the direction of the sun?
But it can mean adjusting the angle and direction every so often or every set period, such as every one to two hours. The more direct that the sun's rays are towards the food and cooking pot the greater the energy (heat) capacity will be from the sun's converted rays.
When to use solar oven?
Ideal cooking results when using a solar oven occur when the sun is bright and uninhibited or unimpeded by clouds, shadows etc . Cooking can be accomplished as well on days when the clouds are high and thin, but it may slow things down a bit, and one would be wise to start a little earlier than usual.
