Advantages of a solar cooker:

  1. As heating is done using solar radiations there is a saving in fuels, consumed such as coal, kerosene, LPG, etc. It also saves electricity.
  2. A solar cooker produces no smoke and hence causes no pollution.
  3. The nutritional value of the food is preserved as food gets cooked very slowly.
  4. There are no hazards such as fire, electric shock or bursting of gas cylinder.

Disadvantages of solar cooker:

  1. It cannot work in a closed room.
  2. It cannot work in cloudy and rainy days.
  3. The reflector has to be adjusted each time to the sun.
  4. Baking and frying take a lot of heat energy which cannot be done on the solar cooker.

Places where weather always remains cloudy would have limited utility of a solar cooker.
