Once the Sun’s
ray reaches the Earth, they can be captured and converted into electricity in
two ways- through solar cells and solar thermal systems.
·
Solar cells change sunlight instantly into electricity.
Groups of small solar cells can be used to power wristwatches, calculators and
other electronics. Larger group of solar cells – linked together in what are
called solar panels – can help power homes, buildings and communities. The
scientific name for solar cells is photovoltaic (PV) cells, which comes from
the word photo, meaning light, and voltaic, meaning energy.
·
Solar thermal systems use the sun energy to heat liquids to
the point that they turn into seam. The steam can then be used to power a
generator that creates electricity for us to use.
The equipment
that produces solar energy can be placed on roof tops or on the ground close to
where the energy will be used. Also, the power can be fed into the electric
grid that serves everyone in a region.
