Solution 1

Solar cooker uses Sun’s energy to heat and cook food. It is inexhaustible and clean renewable source of energy. It is free for all and available in unlimited amount. Hence, operating a solar cooker is not expensive.
Disadvantage of a solar cooker is that it is very expensive. It does not work without sunlight. Hence, on cloudy day, it becomes useless.
The places where the days are too short or places with cloud covers round the year, have limited utility for solar cooker.

Solution 2

The advantages of using a solar cooker are as follows.
       a) It does not require fuels such as coal, kerosene and liquefied petroleum gas (LPG).
       b) It does not produce harmful smoke that pollutes the air.
       c) It does not spoil the nutrients in food.
       d) It allows for the preparation of more than one item at a time.

The disadvantages of using a solar cooker are as follows.
       a) It cannot be used to cook food at night.
       b) A cloudy sky affects its working.
       c) The direction of the reflector has to be changed from time to time.
       d) It cannot be used for baking.
