TYPES OF SOLAR PANELS

The solar panels are of many different types serving numerous purposes depending on their requirement and usage. Beside being solar energy to be reliable and efficient, it is also considered to be very cost effective in nature. The industries have categorised the solar panel according to their demand, generation phenomenon and storage of the sun’s energy in a very effective and convenient way. There are so many factors on the basis of which solar panels are categorised such as location factor, generations , junction layers etc. Now here we will be classifying the various types of solar panels depending on the generation of electricity and the material being used along with the efficiency rate of producing electricity.

1st Generation Solar Panel:

Monocrystalline Solar Panel (Mono Si):

These solar panels are made up of monocrystalline silicon which is considered to be the purest form of any silicon material. The panel is almost a uniform dark colour cell like structure with the edges being rounded shape. Purity feature of silicon made this solar panel to be highly efficient in their working performance. These types of panels are long lasting, occupy a very little space and have a high output rate. The one more important feature of this panel is that they are not much affected by the surrounding temperature unlike the other categories of solar panels.

Polycrystalline Solar Panel (Poly Si):

These panels can be easily differentiated as they look like square patterns and bluish in colour.These solar panels are built up by melting raw silicon which is considered to be cheaper, efficient and faster or quicker than any other processes. These panels are extremely affected by the temperature so they need some extra care and attention in their location area and are used completely depending upon the situations specified.

2nd Generation Solar Panels:

Thin Films Solar Cells:

These solar panels are constructed by placing one or more films of photovoltaic materials such as silicon or cadmium to a substrate. They are cheaper and easier to use and perform better in their output producing rate. Also a very lesser amount of material is also needed for their preparation. They are flexible, durable and are very less effective to temperature conditions. The only disadvantage is that they have a very large size and occupy a big space so they are less suitable for residential applications.

Amorphous Silicon Solar Cell:

These are very commonly used in terms of solar powered packed pocket calculators. These layers utilize triple layer technologies in their manufacturing processes.They are very cheap and easily affordable by the common customers.

3rd Generation Solar Panel:

Cadmium Telluride Solar Panel:

This type of solar still emulates the working phenomenon of photosynthesis. It uses the cadmium telluride material. It is the panel which requires the least amount of water for its manufacturing. This panel will also keep the lowest carbon footprint.

Concentrated PV Cell:

These panels generate electricity the same as conventionally other panels produce. The structural difference is that they have effective curved surface mirrors, lenses, sensors and they also inculcate inherent cooling systems. They are considered to be the most effective and utilized solar panels with highest performance efficiency and production rate. A solar tracker is used which is responsible for absorbing the sun’s energy.
