With the increasingly serious environmental problems, solar energy, as a clean and renewable energy source, is receiving increasing attention from people. As the core component of solar power generation systems, the manufacturing process of solar panels is naturally of great concern. The following is a detailed process for the production and manufacturing of solar panels.
1、 Overview of solar panels
Solar panels are mainly composed of three parts: solar panels, controllers, and inverters, whose main function is to convert solar energy into electrical energy. Solar panels are the core part of solar panels, which are mainly composed of solar panels, EVA, glass, back panels, and other components.
2、 Solar panel manufacturing process
1. Preparation of raw materials
The first step in manufacturing solar panels is to prepare raw materials, including solar cells, EVA, glass, back panels, etc. The quality and performance of these raw materials directly affect the performance and quality of solar panels.
2. Component production
The production of solar panel components mainly includes the following steps:
(1) Sort the solar cells and place them with different color differences.
(2) Cutting solar cells
(3) Series parallel solar cells: Place solar cells in a series welding machine and connect them in a certain series parallel manner to obtain the required voltage and current.
(4) Laying EVA: Laying EVA on and below solar cells to serve as a bonding, sealing, and insulation material.
(5) Glass packaging: Place solar cells coated with EVA on top of glass and then package them to protect the solar cells and improve their reliability.
(6) Backboard packaging: Place the packaged solar cells on the inside of the backboard, and then perform another packaging to prevent moisture and gas from entering the interior of the solar cell module.
3. Quality control
During the manufacturing process of solar panels, quality control runs through the entire process. From quality control of raw materials to strict control of various production processes, all are aimed at ensuring that the quality and performance of solar panels meet standards. Quality control personnel will conduct strict testing on each link, including the appearance and performance testing of solar cells, as well as the integrity of EVA and backplane. Only through strict quality control can the quality and reliability of the final product be ensured.
4. Finished product inspection and packaging
Finally, the solar panels that pass the quality inspection will undergo the packaging process. During this process, the solar panels will be placed in good performance packaging such as shockproof, moisture-proof, and dustproof to protect the safety of the solar panels during transportation and storage. At the same time, each solar panel will be accompanied by a corresponding quality inspection report, so that customers can understand its performance and quality.
3、 Key and Difficulties in Solar Panel Manufacturing
Selection of raw materials: The performance of solar panels largely depends on the quality of the raw materials. Therefore, selecting high-performance, stable, and durable raw materials is crucial.
Precision control of component production: During the production process of solar panels, it is necessary to strictly control the accuracy of each component, including the arrangement of solar cells, the laying thickness of EVA, etc., to ensure its performance and quality.
Dust and dirt prevention during the manufacturing process: During the manufacturing process, dust and stains can have a serious impact on the performance of solar panels, so strict dust and dirt prevention measures need to be taken.
Strict quality control: In order to ensure the quality and reliability of solar panels, it is necessary to strictly control the quality of each production process, as well as conduct strict quality inspection and testing.
The manufacturing process of solar panels is a highly technical and precise task, from raw material preparation to finished product packaging, every step is related to the quality and reliability of the product. Understanding the manufacturing process of solar panels helps to better understand the inherent mechanisms and characteristics of this clean energy technology. With the continuous development of solar energy technology and the continuous reduction of costs, the application prospects of solar panels will be broader, and their manufacturing process will continue to be optimized and innovated.If you want to know more about solar panels, please contact us, the solar panel manufacturer – Huanqi Technology (Shenzhen) Co., Ltd.
