Are you planning to buy a solar panel? You must be considering factors such as energy efficiency, cost, and aesthetics. Although these factors have significance, the factor in solar panels to affect all three of these are the solar panels' types you choose from. The solar panel types presently on the market will influence its installation and manufacturing cost as well as their appearance above your roof.
Three types of solar panels are there with their respective features. But, for the convenience of cleaning solar panels in California, the perfect solar panels will depend on your certain situation and what you expect solar panels to accomplish for you.
That is why if you wish to buy solar panels online, you must know about their types. The three categories of solar panels are monocrystalline, polycrystalline, and thin-film solar panels. All are made in a unique method and their aesthetic appearances are different. Let us find out,
Monocrystalline Solar Panels
They are the oldest type of solar panel and the most improved. They are made from around 40 monocrystalline solar cells. The solar cells are comprised of pure silicon. During the manufacturing process, a silicon crystal is situated within a vat of molten silicon. Afterward, the crystal pulled out of the vat softly, letting the molten silicon form a solid crystal shell around it. It is called an ingot, which is then sliced thinly into silicon wafers which are made into the cell, and then the cells are gathered together to create a solar panel.
The solar cells seem black due to the way sunlight communicates with pure silicon. As the cells are black, there’s a range of colors and designs for the back sheets and frames. The monocrystalline cells are square-shaped with the corners removed, causing small gaps between the cells.
Polycrystalline Solar Panels
Comparatively, these solar panels are a newer entry. However, they are quickly growing in popularity and effectiveness. Similar to monocrystalline solar panels, polycrystalline cells are comprised of silicon. However, polycrystalline cells are developed from fragments of the silicon crystal melted together. In the manufacturing process, the silicon crystal is positioned in a vat of molten silicon. Rather than pulling it out slowly, this crystal is let fragment and then cool. After the new crystal is cooled in its mold, the fractured silicon is thinly sliced into polycrystalline solar wafers. Later on, these wafers are clubbed together for creating a polycrystalline panel.
The cells are blue-colored as the sunlight reflects on the crystals. Sunlight reflects off of silicon fragments in a different way than it does so with a pure silicon cell. Normally, the back frames are silver with polycrystalline, however, there can be a difference. The cell is square-shaped, without gaps between corners of cells.
Thin-Film Solar Panels
These solar panels are quite a new development in the solar panel industry. The most unique feature of thin-film panels is that they aren’t made mandatorily from silicon every time. They can be made of a wide range of materials, like cadmium telluride, amorphous silicon, and Copper Indium Gallium Selenide. These solar cells are formed by situating the core material between thin sheets of conductive material with a layer of glass on top to protect. The a-Si amorphous silicon panels apply silicon, but non-crystalline silicon topped with glass.
The thin-film panels are easily identifiable by their thin appearance. They are almost 350 times thinner than those that employ silicon wafers. However, thin-film frames can often be large to make the look of the complete solar system commensurate with a monocrystalline or polycrystalline system. These cells can be black or blue, based on the material used to make them.
Inference
Apart from manufacturing and looks, there are a few variations in the way each of the types of solar cells functions. The principal parameters are efficiency and price.
The Best Type
The most suitable type of solar panels is based on the objective of the panels and their places of installation. In the case of residential properties with a large roof space or property, the ideal choice could be polycrystalline. They are the most affordable for large spaces to provide sufficient power and efficiency. In the case of residential properties with smaller spaces, monocrystalline solar panels could be the apt choice. They perform well for those willing to optimize their energy bills in a small space. So, it is imminent that monocrystalline solar panels and polycrystalline solar panels are suitable for homes and other similar buildings. On the contrary, thin-film solar panels shouldn’t be applied to homes due to their lower efficiency. Rather, thin-film solar panels are appropriate for commercial buildings that can’t manage the extra weight of conventional panels. Despite their lack of efficiency, commercial roofs have larger space to cover more with panels.
Conclusion
If you’re confused about the type of solar panels that will work suitably for your project, you can take advice from the solar panel cleaning services in California to zero in on the right panels for your property.
