The “solar panel” can be said to be the core of the solar power generation system.
Is it possible to determine what criteria should be selected when installing?
Even if you say the Solar companies in Pakistan and the materials of manufacturing methods are different, and each has its own merits
It is important to understand the characteristics of the panels and make a selection that suits the installation environment and the customer’s circumstances to generate power more profitably and smartly.
This time, we will introduce the types of solar cells that make up such a solar panel.
This will affect the cost of installation and the power generation efficiency after installation, so please refer to it when choosing a panel.
Silicon is the Most Popular Material for Solar Panels.
Solar panels are broadly classified into “silicon-based,” “compound-based,” and “organic-based,” and among these, “silicon-based” solar panels are particularly widespread around the world.
For this reason, the price range is easy to purchase according to your budget, and there are many panel designs to choose from, making it easy to find the one that suits your roof.
Why are “Silicon-Based” Solar Panels the Mainstream?
Silicon, also known as “silicon”, is the second most abundant substance on earth after enzymes. Because it is a “semiconductor”, it conducts electricity under certain conditions. For example, one of the conditions is to “apply light” as shown in the image above.
Sunlight Activates the Silicon in the Solar Panel and Produces Electricity.
These properties make silicon the most popular choice for solar cells.
Features of 3 types of “silicon-based” solar panels
Three types of silicon are commonly used in solar cells, and among them, “crystalline silicon”, “single crystal” and “polycrystalline”, are mainly used as solar cells in solar panels.
I will explain the characteristics of each silicon solar panel in detail.
Monocrystalline Silicon Panel
“Monocrystalline” silicon panels are the oldest and most proven of the current solar technologies.
A module is constructed by slicing a silicon ingot (*1) and laying the octagonal ones cut on all four sides.
Since the silicon atoms are arranged regularly and have high purity, the power of silicon can be maximized and the power generation efficiency is high.
A large amount of power generation can be expected even with a small installation area. So a sufficient income from power sales can be obtained even in a house or a small roof.
However, since high-purity single-crystal silicon is expensive, many products are relatively expensive, and the initial cost is high.
Polycrystalline Silicon Panel
Currently, the most widely used panel in Japan is the “polycrystalline” silicon panel.
A module is constructed by collecting small objects such as scraps left over from the manufacturing of monocrystalline silicon and scraps of ICs.
Since it is manufactured by reusing silicon that became defective in the process of making solar cells, it is possible to mass-produce it at a low cost.
Since it is less pure and cheaper than single crystals, it is recommended to use it in places. Where a large area can be obtained, such as a large area of land or the roof of a factory.
However, since the power generation efficiency per unit area is inferior to that of monocrystalline silicon. It takes time to recover the initial cost.
Thin film (amorphous) silicon panel
It is made of silicon that does not require crystals and is characterized by being extremely thin and lightweight compared to conventional solar panels.
It uses an amorphous element in which very fine silicon elements are arranged irregularly.
Above all, the biggest advantage is that the price is cheap, but compared to the crystal type, the amount of power generated per panel is about half.
However, it has many uses, such as being easy to manufacture, being lightweight and heat-resistant, and being able to be manufactured in a form that can be attached to glass or stainless steel.
CIGS System” Latest Attention Panel!
Recently, to reduce weight and increase efficiency, research and development of compound-based and organic-based hybrid solar panels are underway.
Solar panels that are classified as “compound solar panels” are attracting particular attention. And panels that have just begun to be put into practical use called “CIGS solar panels” are attracting particular attention.
It is a semiconductor that combines raw materials such as “copper (Cu ), indium ( I ), gallium ( Ga ), and selenium ( S e). Compared to silicon, the power generation efficiency is lower, but it can be used in high-temperature environments such as in summer. It has the characteristic that the output efficiency does not easily decrease even at low temperatures. The color of the panel surface is pure black, and the design is excellent. It is expected to become a mainstay panel comparable to silicon-based panels.
“Single-crystal” silicon is expected to generate a large amount of power even in a small area.
“Polycrystalline” silicon that can be installed in numbers at low cost.
We hope that you will choose a Solar Panel Lahore that makes the most of each feature.
