Henan Shengshi Optics Valley Energy Technology Co., Ltd.

The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower. The photoelectric conversion efficiency is about % (the world's efficiency is . Highest efficiency polycrystalline silicon solar cells). In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The materials are simple to manufacture and save power consumption. The overall production cost is low, so it has been widely developed. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.

current and voltage tests and be strictly graded to ensure that they meet the power requirements.
★The product has the characteristics of waterproof, pressure resistance, corrosion resistance and long life; it uses high-strength, anti-corrosion aluminum alloy frame packaging components to ensure the mechanical performance of the solar panel;
●Solar panel manufacturing process And quality management:
During the production and manufacturing process, in addition to grading by power, all solar modules are also classified by current to improve the overall performance of the system and the life of the solar panel and reduce resistance and overheating. After lamination, the outer frame of the solar panel is added with an anti-corrosion aluminum alloy frame. High-quality raw materials and components can withstand various harsh climatic conditions, making the solar modules waterproof, pressure-resistant, corrosion-resistant, and long-life.
●Testing and inspection of solar panels:
The quality monitoring process runs through the entire process of cell and module production. Before packaging, all solar modules must pass % current and voltage tests and be strictly graded to ensure that they meet the power requirements. Strict, thorough and uncompromising inspection procedures ensure that all products delivered to customers are of the highest quality.
Solar panels are widely used in: solar power stations, solar power generation systems, solar street lights, solar garden lights, solar cars and other fields.
