What are the Benefits of Solar Panel and how it Works?

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.
