The working of solar panel working may be a little-prolonged activity for the layman customers. The photovoltaic effect is the process whereby sunlight gets turned into electricity. Few materials showcase this property that causes them to absorb the photons of light and releases electrons. When the free electrons get grabbed, an electric current leads to the generation of electricity.
A solar cell is an electronic device which
catches the sunlight and turns it into the electricity directly. These cells
are of the same size as the palm of an adult ( blue-black and octagonal).the
solar cells (photovoltaic cells) are usually bundled together to create a big
unit of solar modules and is called as solar panels. Solar cells have germanium
PN junction diode and silicon with a glass window on the top surface layer of
P-type. The top surface layer of P-type material is thin so that the incident
light photon may quickly reach the PN junction.
Sunlight may
generally consist of photons, and these photons have a different amount of
energy corresponding to various wavelengths of light. When these photons in
sunlight hit the solar cells, they are either reflected or absorbed. If the
photon gets absorbed, its energy gets transferred to an electron in the cells'
atom. Then the electron escapes from its normal position, thus causing a hole.
Due to these holes and electrons, there is a production of current.
The process
is known as the photovoltaic effect. The current generated is collected by
wiring the individual solar panels together. These cables terminate into an
electrical box known as 'combiner box' that drives the current to the inverter.
The inverter set in an accessible location converts the DC electricity into AC
so that it can be placed to direct use.
Advantages of Solar Photovoltaics:
a) These
cells are quite easy to maintain
b) It saves
electricity bills
c) Though
they may be a high cost in the starting, the rates get recovered in the long
run
d) You will
get extra payments for any surplus energy that is being sold back to the grid.
e) With the
installation of solar photovoltaic, you get paid feed-in-tariff for each unit
of solar electricity that you produce.
f) They
don't generate any noise or greenhouse gas.
