Solar Panel - Types and Uses

Solar Panel Manufacturers
A solar panel is a collection of solar cells that converts photo-electric energy into electrical energy. These photovoltaic cells are generally arranged in grid-like structure so that it can absorb photons in a large amount and generate more electricity. Solar Panel construct these by utilizing semi-conductor materials - silicon and gallium arsenide because of their appreciable optical properties. Actually, the usage of material while constructing solar panel depends on the type of application area - residential or industrial and the amount of output power required. For installing Solar Panel at residential places or commercial places, roof is the best location. Apart from roof, there are various other mounting options also available such as trackers, standard ground mount, shade awnings and so forth.

Solar panel works only when exposed to sunlight where photons strike the surface and get converted into electrical energy; basically in this process, structure of photons breaks down and free electrons flow after coming in contact with metal and produce current. In order to generate high electric output, solar panel must be highly efficient and its efficiency depends on following three factors :

a) number of solar cells fixed on the surface of panel
b) amount of solar radiation it receives
c) place where it is installed

What are the different types of Solar Panels?
There are numerous kinds of solar panel, from an ever increasing range of manufacturers. Some solar panel types are discussed below:

Mono-Crystalline Panels

These panels are constructed by using silicon material only, which is further known for its efficiency and better performance. During installation, the entire cell is aligned in single direction so that it works efficiently when exposed to sun, especially when sun shines brightly. This Mono-crystalline solar panel is generally used for industrial applications, where higher power is needed.

Polycrystalline Panels

Unlike mono-crystalline where silicon slices are used, polycrystalline panels are constructed from silicon offcuts which are further molded to form rectangular blocks. This kind of panel can work better in low light too but as it contains less amount of silicon, a slight difference is there in the efficiency as compared to mono-crystalline panel.

Hybrid Panels

This panel uses amorphous silicon technology in which a thin layer of amorphous solar film is formed behind the monocrystalline cells. This layer collects more energy from the available sun rays, especially in dim light conditions. Hybrid panels work efficiently in small roof space by delivering large amount of electric power. This panel has easy installation and can be utilized for residential purposes.

Black Framed Panels

“Black Framed Panels” or “All Black Panels” are used to produce large amount of electric power by absorbing large quantity of sun light. In this type of panel, all photovoltaic cells are placed onto a black panel surface and most commonly fixed on household slate roofs.

What are the Various Advantages of using Solar Panel?

People can have numerous benefits by installing required solar panel. Some are discussed below:

Maintains Clean Environment – Solar energy is clean and renewable therefore, it does not causes any adverse effect on environment unlike fossil fuels and nuclear power. 

Saves Electricity Bills – Once solar panel is installed, people can have free electricity and they would not have to pay heavy electricity bills.

Saves Natural Resources – Solar Panel works on renewable source of energy i.e solar energy, which is present in abundance. Therefore, this can save fossil fuels such as coal, petrol and natural gas.

Requires Less Maintenance – Solar Panel can deliver its performance for almost 20 years consecutively with negligible maintenance.

Best for Remote Locations – Solar panel can be installed in those places where electricity supply is not possible.
