Changhui Lighting: Exclusively revealing the production process of solar street light panels

Solar street lights are composed of solar panels, solar controllers, batteries, LED light sources, light poles and other parts, and solar panels are the core part of solar street lights and the most valuable part of solar street lights. The basic production process of solar cell modules will be discussed with you: (1) All raw materials should be prepared before the production of the prepared components, including: batteries, backplanes, EVA, glass, junction boxes, silica gel, etc. (2) Welding First weld the front side of the battery, then turn the battery over and then weld the back side of the battery, and finally connect the battery into a string. (3) Laying Arrange the welded battery strings according to the requirements of the process drawings, and then lay the glass, EVA, battery strings, EVA, and backboard in order from bottom to top. (4) EL test First perform EL test on the radiated cells above, mainly to keep the series batteries free of hidden defects and mismatches. (5) Lamination Laminate the laid components. (6) framing Perform EL test on the laminated components to ensure that there are no cracks and fragments, and then perform the framing operation, install the junction box, and dry the silica gel after passing the inspection and transfer it to the wiping process. (7) Wipe Wipe and clean the surface of the component. (8) Test The assembled components are tested again, and the appearance of the components is inspected to ensure that the components received by the customer are all high-quality components.
