A solar cooker works on the principle of conversion of light energy to heat energy and entrapment of the heat energy.
A solar cooker is uses the energy of direct sunlight on dark black glass sheath which helps to heat, cook or pasteurise drinks and other food materials.
Solar heater works on the same principle as the cooker but its uses are different. It is used as a heater and encourages the process of heating.
Israel was one of the first countries to use the process and made the use of solar heaters mandatory.
