Question
A solar water heater cannot be used to get hot water on
- Hot day
- Sunny day
- Windy day
- Cloudy day
Hint:
Solar Energy harnessing needs Sunny Days.
The correct answer is: Cloudy day
- On a cloudy day, the clouds cover the sun
- So the solar panels won't get any energy from sun and it cannot generate electricity(which is used to run water heater).
- Hence solar water heater cannot be used on cloudy day.
