What types of solar panels are there?
Cost, aesthetics and energy efficiency are often considered when the numerous benefits of solar panels are considered in the purchase and selection of solar panel products for development. While these are important factors, there is one more factor in solar panels that affects all three: the type of solar panel you choose.
How many types of solar panels are there? There are three different types of solar panels, each with its own advantages and disadvantages. The right solar panel will depend on your specific situation and what you want the solar panel to do for you. We will discuss the types of solar panels, the advantages and disadvantages of each type, and how to choose the type of solar panel Z is right for you.
What are the types of solar panels? The three different types of solar panels are monocrystalline silicon solar panels, polycrystalline silicon solar panels and thin-film (amorphous silicon) solar panels. Each type of solar cell is manufactured in a unique way and has a different aesthetic appearance. The following are introduced:
Monocrystalline silicon solar panels are the earliest solar panels, but also developed, there is a more mature process. These monocrystalline silicon solar panels are made from about 40 monocrystalline silicon. These solar cells are made of pure silicon. During the manufacturing process, silicon crystals are 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 crystalline shell around it, called an ingot. The ingots are then cut into thin silicon wafers. Silicon wafers are made into batteries, which are then put together to form a solar panel. Single crystal solar panel surface appears blue, four Angle guide Angle is missing, the conversion efficiency is usually about 18-24%.
Polysilicon solar panels have only been developed in recent years, but they are rapidly increasing in popularity and efficiency. Like monocrystalline silicon solar panels, polycrystalline silicon cells are made of silicon. But polycrystalline cells are made by melting together fragments of silicon crystals. During the manufacturing process, silicon crystals are placed in a VAT of molten silicon. Instead of pulling the crystal out slowly, you let it crumble and cool down. Then, once the new crystal has cooled in its mold, the cracked silicon is thinly sliced into polycrystalline solar silicon wafers. These silicon wafers are assembled together to form a polysilicon plate. Polysilicon solar panels also appear blue, but they show a variety of colors when exposed to certain light, with a conversion efficiency of about 14-18%.
Thin-film solar panels are a very recent development in the solar panel industry. What stands out about thin-film panels is that they are not always made of silicon. They can be made from a variety of materials, including cadmium telluride (CdTe), amorphous silicon (A-Si) and copper indium gallium selenium (CIGS). They are characterized by great flexible strength compared to crystalline silicon solar panels, but their conversion efficiency is only 7-14%, and their appearance is very easy to distinguish. Compared with other solar panels, his price is high, perhaps because his production life is relatively short, the process is not as mature as polysilicon and monocrystalline silicon.
After introducing the types of solar panels, it is relatively clear how to choose solar panels.
