A ‘solar water heater’ cannot be used to get ‘hot water’ on (b) “a cloudy day”.
As the solar water heater works on solar energy. It is composed of some solar panels which heated the liquid with the help of solar energy.
As the liquid / water is passed through the storage tanks, the heat energy is transferred to water. Overall it involves the conversion of solar energy to heat energy. Hence it will not work on a cloudy day as no sun will be there to provide solar energy.
