سیستم پنل خورشیدی به این صورت است که می تواند انرژی خورشید را دریافت و آن را به الکتریسته تبدیل کند.

Polycrystalline solar panels are made from similar silicon material hence instead of going through the slow and more expensive process of creating a single crystal, molten silicon is just put into a cast and cooled with a seed crystal. By using the casting method, the crystal surrounding the seed isn’t uniform and branches into many, smaller crystals, thus the term “polycrystalline”. The surface has a jumbled look with many variations of blue color. Amerisolar has developed various types of polycrystalline solar modules.

Polysilicon consists of small crystals, also known as crystallites, giving the material its typical metal flake effect. While polysilicon and multi silicon are often used as synonyms, multi-crystalline usually refers to crystals larger than one millimeter.

Currently, polysilicon is commonly used for conducting gate materials in semiconductor devices such as MOSFETs; however, it has the potential for large-scale photovoltaic devices.

The use of polycrystalline silicon in the production of solar cells requires less material and therefore provides higher profits and increased manufacturing throughput. Polycrystalline silicon does not need to be deposited on a silicon wafer to form a solar cell, rather it can be deposited on other-cheaper materials, thus reducing the cost. Not requiring a silicon wafer alleviates the silicon shortages occasionally faced by the microelectronics industry.
