The Sun being a huge fireball with its constituent elements being Hydrogen and Helium undergoes nuclear fusion in an unending cycle. In the core of the Sun, Hydrogen atoms keep breaking into Helium atoms and it takes 4 hydrogen atoms to form 1 helium atom. This repeated phenomenon is why the Sun never ceases to emit energy.
This phenomenon has been occurring for the last billions of years since the Big Bang and would go on to continue for another millions of years. So, the energy that the Sun emits is trapped and stored in the Solar Panels manufactured by different solar cell manufacturers and then it produces electricity. This is how the entire solar energy circle continues.
How do solar panel’s function and what is its working principle?
The typical solar modules which we use are composed of individual solar cells, which are further made of layers of silicon, boron and phosphorus. The Silicon layer acts as a semiconductor, when photons strike the panel surface it knocks out the electrons from the silicon layer and into the electric field generated by solar cells. As a result, directional current is produced which is further harnessed into usable power. This entire process is termed as the photovoltaic effect, which is also the reason why solar panels are also called Photovoltaic Panels or PV panels.
Different types of solar modules that are put to use
Mentioned below are the different types of solar panels.
- Monocrystalline Solar Panels: These are made up of pure silicon which adds to its purity and efficiency, the only drawback being that a lot of silicon is wasted to produce one monocrystalline cell the toll sometimes reaches upto 50% and it is for this reason that these are quite expensive.
- Polycrystalline Solar Panels: As the name suggests these are made up of more than one silicon crystal. There is hardly any wastage of silicon in these types of panels which is also why these are quite affordable but are also less efficient than monocrystalline cells.
- Passive Emitter and Rear Cell panels: These are an improvement of the conventional Monocrystalline cells. Here a passivation layer is added to the rear surface of the cell and hence it enhances the efficiency of the cells.
- Thin-film Panels: unlike the other three panels which are made of Silicon these are made from different materials like CdTe, a-Si, CIGS, etc.
There are many firms engaged in solar module manufacturing throughout the country and beyond. Premier Energies is one such firm dedicated to transforming the energy sector with its expertise in the industry. Established in 1995, Premier Energies set up its first Solar Power assembly line of capacity 3 MW p.a as of now that figure stands at 1.4 GW assembly line and 700+ MW solar cell manufacturing capacity. It is with their commitment and dedication towards transforming today for a better tomorrow that has made Premier Energies the largest integrated solar manufacturer in Southern India and the second largest in whole of India.
