Zhonghao professional R&D team can customize personalizede Semi-automatic or fully automatic production lines based on different customer needs,including factory layout,equipment deployment and production line planning,to improve the automation level of the solar panel production,increase production efficiency,and reduce the manpower.
If you want to set up a solar panel production line, and you have no idea about what machines do you need or how to configure the device. We are your best choice. As a professional manufacturer of photovoltaic equipment,we can design professional solar panel production line for our customers(from 50MW to 1GW) , so please feel free to contact us.
The solar panel production line is a complete automated production system for producing photovoltaic modules, covering multiple production steps from a single cell to the final finished module. Through a series of special equipment and automation technology, the production line assembles solar cells into photovoltaic modules of standard size and is widely used in the global photovoltaic power generation industry. With the growth of clean energy demand, the automation and intelligence of solar panel production lines are constantly improving, greatly improving production efficiency and product quality.
Overview of the production process：
1. Cell string welding:
Single cells are welded in series to form a cell string. The automated string welding machine uses laser positioning and welding processes to ensure that each cell is accurately connected, and the solder joints are firm and conductive.
2. Laying and layout:
The cell strings are arranged and placed on the pre-laid EVA (ethylene-vinyl acetate copolymer) film and glass substrate to ensure that the cells of the module are evenly arranged and the photoelectric conversion efficiency is maximized.
3. Lamination:
Through lamination equipment, high temperature heating and pressure are applied to firmly bond the glass, EVA, cell and backplane layers together to form a tightly structured, waterproof and dustproof component.
4. Framing and edge milling:
The aluminum alloy frame is installed on the component to enhance the mechanical strength of the component, facilitate transportation, installation and provide additional protection. The edge sealing process can also prevent moisture and dust from invading the interior of the component.
5. Electrical performance test:
Electrical tests are performed on the encapsulated components, including current-voltage characteristic test (I-V test) and 6.EL test (electroluminescence detection) to ensure that the components meet the power and performance requirements, and defective products are discovered and removed in time.
7. Cleaning and packaging:
The surface of the components is cleaned to remove residues from the production process. The qualified components are then packaged and prepared for shipment.
