Answer 2

The statement given above is true.

Explanation:

• Solar panels that are used to heat water or any other type of solar panel are generally covered by black metal sheets.

• Black metal sheets absorb and attract a much larger amount of heat as compared to any other metal.

• We know that black surfaces are perfect absorbers. A perfect absorber is one that absorbs all the light that is incident on it.

• As only black surfaces are known to perfect absorbers hence they are widely used in solar panels.
