Option (B) a cloudy day
Solar energy is the energy that we receive from the sun. Therefore, the heater will not get enough solar energy and the water will not heat. On a cloudy day, heat radiation coming from the sun do not reach the solar water heater. Hence, the solar water heater cannot be used to heat water on a cloudy day.
Solar energy and its benefits
Solar energy is obtained from the sun’s radiation, and it can be converted to electricity or heat. It has the least negative impact on the environment compared to any other energy source. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.
- Solar energy does not emit toxic substances or contaminants into the air
- Renewables do not emit greenhouse gases in energy generation processes
- It provides light that is converted into electricity through photovoltaic solar panels.
