How do solar panels work? How many types are there?
There are many benefits of installing solar in your home. Whenever you think about installing solar panels, you usually consider factors such as the cost involved and the energy efficiency achieved. While these are important factors, there is one more factor in solar panels that will affect all three, the type of solar panels you choose.
Friends, whenever the electricity bill comes, our house budget gets ruined by seeing it, is there any such way by which the electricity bill comes down a lot. Thinking of this, the word solar panel starts roaming in the mind.
Today we will discuss in this article what is Solar Panel? How does Solar Panel work?
What is Solar Panel?
It is a device that absorbs the rays coming from the sun and converts them into heat or electricity. That is, it converts the energy received from the sun into electrical energy. Solar Panel Lots of Solar Cells
It is made up of solar power called photons in science. Solar cell converts these photons into electric energy. The electric energy obtained from the solar cell is used by the solar inverter to run home appliances, and can be stored in the battery.
History Of Solar Panel
In 1839, a French physicist named Edmond Becquerel discovered the photovoltaic effect. He made a cell of metal electrodes and found that the cell generated more energy if it was exposed to sunlight.

In 1873, Willoughby Smith discovered that selenium could be used as a photoconductor. Then in 1883, Charles Fritts manufactured the first solar cells from selenium, which was made from drawings of Smith’s discovery.
These solar cells are similar to the ones we use today, but now we make them from silicon instead of selenium. In 1954, Daryl Chapin, Calvin Fuller, and Gerald Pearson built the first silicon solar cell at Bell Labs. All these innovations together have contributed to the development of solar panels.
How does solar panel work? (Working Of Solar Panel)
Before knowing how Solar Panel works, we have to know that Solar Panel is made by mixing Solar Cells, we have told you in the above article, we told you that Solar Cells are made of silicon metal. Which is a Semiconductor. Semiconductor has 4 electrons in its last orbit. So when silicon is doped with a substance that has 5 electrons in its last shell, it is called an N-type (negative type) semiconductor. And when a substance is added to silicon that has 3 electrons in its last shell, it is called a P-type (positive type) semiconductor.
While making a solar cell, we connect these two semiconductors (N-type, P-type) together, so that we get a positive and a negative layer, and a photo-voltaic junction is made between these two layers. This is how solar cells are made.
Working Of Solar Panel
Solar panels are made of very small photovoltaic cells, which means that they convert the light coming from the sun into electricity. These cells are made up of semiconductor material, in which most of the silicon is a material that conducts electricity continuously while maintaining the required electric voltage to create an electric field.
When the Sun’s Solar Power collides with the Semiconductor present in the Solar Cell, the energy from the Solar Power, in the form of photons, is absorbed, with this absorbed energy many electrons of that semiconductor material become free, which are present in the cell. roam freely.
What is solar inverter? (What Is Solar Inverter)
It is a type of Electrical Converter that converts the photovoltaic direct current (DC current) received from the Solar Panel into alternating current (AC current). It is also called Solar Inverter or PV Inverter. We can use the power generated by this to run different types of equipment in our house like TV, fan, bulb etc.
How many types of Solar Panel are there?
There are three different types of solar panels based on their construction, and each has its own advantages and disadvantages. Which solar panel you should take will depend on what your needs are, in this article we will tell you about all three types of solar panels and also some of their advantages and disadvantages.
There are three types of solar panels on the basis of size. And each has its own advantages and disadvantages. If you are willing to buy a solar panel, which solar panel should you take, it will depend on how much power you need, through this post we will tell you about all three types of solar panels and give you It is important to know what are their advantages and disadvantages.
What are the 3 types of solar panels?
1- Solar Panel Monocrystalline
2- Polycrystalline
3- Thin-film solar panels
Monocrystalline Solar Panels
This solar panel is the oldest and most developed, in which about 40 monocrystalline solar cells are made using. Monocrystalline Solar Panels are made of pure silicon. They are prepared by the Czochralski method. In this a silicon crystal is placed in a vat of molten silicon. The crystal is then very slowly pulled out of the vat, allowing the molten silicon to form a solid crystal shell around it called an ingot. The ingot is then thinly sliced into silicon wafers. The wafer is made into a cell, and the cells are then joined together to form a solar panel.
Sunlight interacting directly with pure silicon causes monocrystalline solar cells to appear black. While the cells are black, a variety of colors and designs are available for the back sheet and frame. Monocrystalline cells are shaped like a square with the corners removed, so there are small gaps between the cells.
Polycrystalline Solar Panels
Polycrystalline solar panels are a newer development among the various types of solar panels, but they are becoming increasingly popular in terms of popularity and efficiency. Like monocrystalline solar panels, polycrystalline cells are made of silicon. But polycrystalline cells are formed from pieces of silicon crystals fused together. During the manufacturing process, silicon crystals are placed in a vat of molten silicon. Instead of slowly extruding it, the crystals are allowed to crumble and then cool. Then once the new crystal is cooled in its mold, the fractionated silicon is thinly sliced into polycrystalline solar wafers. These wafers are assembled together to form a polycrystalline panel.
Polycrystalline cells are blue in color because of the way sunlight reflects off the crystals. Sunlight reflects differently from silicon pieces than from a pure silicon cell. Typically, the back frame and frame are silver with polycrystalline, but there may be variations. The shape of the cell is square, and there is no gap between the corners of the cell.
Thin-Film Solar Panels
Thin film solar panels are a fairly new development in the solar panel industry. The most distinguishing feature of thin film panels is that they are not always made of silicone. They can be made from a variety of materials including cadmium telluride (CdTe), amorphous silicon (a-Si), and copper indium gallium selenide (CIGS). These solar cells are made by placing the lead material between thin sheets of conductive material with a layer of glass on top for protection. a-Si panels use silicon, but they use non-crystalline silicon and have a layer of glass on top.
As their name suggests, thin-walled panels are easy to identify by their slim appearance. These panels are approximately 350 times thinner than panels using silicon wafers. But the frames of the thin film can sometimes be large, and this can make the appearance of the entire Solar System comparable to that of a monocrystalline or polycrystalline system. Thin-film cells may be black or blue, depending on the material they are made of.
How to install solar panels in your home (Solar Panel Installation)
You have got all the information about Solar Panel, now it depends on you which Solar Panel to install, according to your house, Solar Panel can be installed, by the way, if we talk about Solar Panel Price, then it is from 10000 to 20000 and one lakh. It comes up to ten lakhs. Due to which you can also run tube wells on the farm for very big tasks. Can be used even in big factories.
Keep one thing in mind that before installing Solar Panel, get complete information about it because many types of subsidies are also given by the Government of India in Solar Panel. So that you get a lot of reduction in Solar Panel Price.
Advantages of Solar Panel
1- You must have seen that most of the electricity goes out in rains, storms, if you install solar panels, then there will be electricity in your house all the time, you will not need any other electricity.
- If you live in a farm where there is no means of electricity, then you can use Solar Panel. You can use electricity as much as you want, it will not cost anything.
3- By installing solar panels once, you will also get rid of the electricity bill every month.
