  2. solar panel

  3. solar battery

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Solar panel refers either to a photovoltaic module, a solar hot water panel, or to a set of solar photovoltaic (PV) modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

Water cannot be heated using a solar water heater on a.

  1. windy day

  2. sunny day

  3. cloudy day

  4. hot day
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Solar water heater works on solar radiation falling on it. It requires solar light for generating enough heat to heat water. During cloudy days, Sun is obstructed by clouds, and the light incident of the solar panels will be inefficient to make the heater work.
