Solar energy
The energy of sunlight
What is solar energy?
Solar energy comes from the light of the sun, which means it is
a renewable source of energy. We can use its light to create
pollution free electricity.
How does solar energy work?
When the sun shines on “solar cells,” they absorb its energy causing
a chemical reaction that generates electricity.
The electricity generated
by these solar cells – or
photovoltaic system – can
be used at homes and
factories or it can be
stored in a battery. This
stored energy then can be
used at night.
