Do you know there are three types of solar panels you might not know about? I am going to tell you more about the panels and as well explain how they work?
There are many photovoltaic (PV) cells in a solar panel. Photons from the sun are absorbed by the Solar cells as they come into contact with sunlight on a solar panel's surface. The cells are stimulated and begin to vibrate, resulting in the generation of an environmentally friendly power. In 1839, Edmond Becquerel discovered the Photovoltaic effect, the name given to this process.
The efficiency of PV panels varies widely. In other words, certain brands and models of solar panels are better at converting sunlight into power than others. This is because the amount and kind of silicon cells in a panel might vary. The cost, size, and weight of a solar panel are often influenced by the number of cells it contains. Although it is often assumed that the higher the wattage and power output of a solar panel, the more silicon cells it contains, the more accurate this is not necessarily. To get the most out of a panel, the quality and efficiency of its solar cells must be considered.
Polycrystalline, monocrystalline, and thin-film solar cells will be covered in this post. The first step in choosing the right panel for your house, company, or community is to understand the differences between the three types of solar panels.
1. POLYCRYSTALLINE SOLAR PANELS
Polycrystalline panels, also known as "multi-crystalline" panels, are often considered middle-of-the-road panels. Polycrystalline Solar panels are less efficient, but they are less expensive.
Polycrystalline cells, like monocrystalline panels, are silicon-based. When it comes to silicon crystals, polycrystalline cells are created by melting together many pieces of the material. Polycrystalline solar panels, as a result, are less efficient and have a shorter life duration. As a result, they don't produce as much power from the sun as Monocrystalline panels do throughout the day. This is because each cell contains several crystals, restricting the electrons' freedom of movement.
Wafers are formed by melting raw silicon and putting it into a square mold, which is how polycrystalline panels are made. Unlike their Monocrystalline counterparts, polycrystalline cells do not need cutting each of the four sides. Because there is less trash, it's better for the environment. Overall, the procedure is more efficient and less expensive than making monocrystalline solar cells. A polycrystalline panel is made by putting these wafers all together.
The blue finish, rectangular form, and speckles in polycrystalline cells are all telltale signs. It's because they have a lot of crystals in each cell, and the light bounces off them that they seem blue and speckled.
2. MONOCRYSTALLINE SOLAR PANELS
Solar panels made of monocrystalline crystals are the oldest and most advanced. Monocrystalline Solar Panels, as the name implies, are made up of solar cells composed entirely of a single crystal of silicon. Pure silicon is made into bars and sliced into wafers to produce these solar cells. To assist the solar cells in generating even more power, the edges of the cells are rounded, smoothed, and chopped off during this procedure. Although it's time-consuming and inefficient, this provides monocrystalline cells a distinct look.
Monocrystalline solar panels are among the most expensive on the market since they are made from the purest silicon. Although monocrystalline cells have a higher price tag, they tend to survive longer and perform better than other types. With a single crystal forming the cell, the cells produce more power. They also seem black and uniform in appearance, like Monocrystalline cells do. As a result, they are the best option for anybody seeking a contemporary black solar panel.
3. THIN-FILM SOLAR PANELS
Thin-film solar panels, unlike monocrystalline and polycrystalline solar panels, are flexible, low-profile, and thin. In monocrystalline and polycrystalline panels, the crystalline wafers are 350 times thinner than the cells inside the panels.
Semiconducting materials such as silicon, cadmium telluride, and copper indium gallium selenide make thin-film solar panels. On top of the semi-conductor is a glass layer, which aids in the absorption of sunlight. However, thin-film solar panels utilize silicon, which is not the same as solid silicon wafers. Because it's not crystallized, it's a different kind of silicon.
Compared to crystalline panels, thin-film solar panels have poorer efficiency and power capabilities. They need a lot more roof area to produce a lot of solar energy since their efficiency is approximately 11%. Additionally, they decay more rapidly than crystalline panels, resulting in shorter warranties.
Despite this, there is still a role for thin-film solar panels in the industry. There are several uses for thin-film panels due to their flexibility. Even if you don't like the look of solar panels, you may still go solar by having them molded into shingles or solar roof tiles.
WHICH SOLAR PANEL TYPE IS THE BEST?
So, what is the best solar panel? A project's scope and budget are the two most important factors when selecting a solar panel. Due to their cost, monocrystalline solar panels still have a position in the household market. Conversely, if the roof area is more minor, monocrystalline cells are the preferable option. Commercial and historic buildings may benefit from the low weight of thin-film solar panels, which are seldom utilized in residential homes.More posts to read
