Every day is a step forward towards a technologically advanced world. When it comes to the energy sector, we’re way past those days when we had to depend on coal, and petroleum to produce electricity. Now, we are progressing towards solar energy for most of our power requirements. Therefore, finding solar panels on roofs, and on the roads is not an extraordinary sight anymore.
Not only commercial and industrial establishments are investing in solar panels, but private establishments are also doing the same.
So, if you are planning to depend on solar panels for your energy needs, it’s essential you know about the basics of a solar panel. Today, we will be telling you all about solar panels, including how it works and the types in this guide.
What are Solar Panels?
A solar panel is a device made of photovoltaic cells, also known as PV cells. The PV cells in the solar panels absorb the energy released by the sun. This energy is also called solar radiation and electromagnetic radiation. Every location on the planet receives this solar radiation, however, the amount varies according to the location and its climate.
A solar panel works by converting the stored energy into electrical energy. The conversion is possible when the electrical charges created by the panels move in reaction to the electric field in the cell, allowing the movement of electricity.
Types of Solar Panels:
There are three kinds of solar panels. These solar panels are defined by the technology they use.
1. Monocrystalline Solar Panels:
Monocrystalline solar panels are made of a silicon block. As the name of the solar panel indicates, these types of panels are made of a single silicon block. The block is cut into multiple wafers and is assembled with a back sheet, forming the exterior of the solar panels.
Monocrystalline solar panels are one of the most efficient solar products on the market. They are known for their high efficiency. This type of solar panel can have an efficiency higher than 20 per cent. They generate more power as compared to other types of solar panels because of their high efficiency, as well as high wattage modules. Most monocrystalline solar panels are available in more than 300 watts (W) of power capacity, a few exceeding 400 W.
However, being highly efficient, they are expensive. This is because of its long durability, high-power output, and compact size. However, you don’t have to be bothered by the high price. Solar panels can last 15-20 years depend on the quality
2. Polycrystalline Solar Panels:
Just like a monocrystalline solar panel, a polycrystalline solar panel is made of fragments of silicon blocks that are melted in a mold before being divided into thin wafers.
Even though this type of solar panel doesn’t provide high efficiency as compared to monocrystalline solar panels, it is cost-efficient.
3. PERC Solar Panels:
The third type of solar panel is Passivated Emitter and Rear Contact (PERC) solar panel. This type of solar panel has an additional layer within the cell, allowing the sunlight to reflect light into the solar cell. The fact that they are the modification of conventional cells, they can be made using the same equipment. In addition to this, they are highly efficient as they can produce a high amount of energy with limited panels.
The Final Word:
Now that you know the basics of solar panels, you will be able to buy solar panels with ease. In case, you cannot decide which type of solar panel to buy, you can begin by analyzing your requirements. If you want something cost-effective, polycrystalline solar panels are the ideal pick. If you are prioritizing high efficiency, then monocrystalline solar panels should be your choice. Whichever you buy, ensure that you are buying it from reputable brands such as Luminous. Luminous has been India’s top brand for power solutions. You will be only buying the best when you are buying it from Luminous.
