How to Repair Solar Panels

After the solar panel half-cell 5bb solar panel is used for a long time, the function and power generation of each component will gradually decrease, which is an unavoidable loss. Solar panel failures caused by extreme weather or human error can be handled and prevented. Let me introduce you to solar panel repair methods.
How to Repair Solar Panels
1. EVA delamination
When the delamination area is small, the high-power failure of the module will be affected. When the delamination area is large, the module will fail and be discarded directly.
①Strictly control the important parameters such as the temperature and time of the laminator, and do the cross-linking degree test regularly according to the requirements, and control the cross-linking degree within 85%±5%.
②Strengthen the improvement of raw material suppliers and the inspection of raw materials.
③Strengthen the appearance inspection of finished products during the process
④Strictly control the amount of flux, try not to exceed 0.3mm on both sides of the busbar

2. Hot spots and delamination
The power attenuation failure of the module caused by the hot spot may directly lead to the failure of the module to be incinerated and discarded.
① Operate strictly in accordance with the rework requirements, and pay attention to 5s after rework.
②The temperature of the soldering iron at the welding place should be controlled in accordance with the specification at the time of the welding machine.
③ Regularly check whether the parameters of the laminator meet the process requirements, and at the same time, do the cross-linking degree test on time to ensure that the cross-linking degree meets the requirements of about 85%.
3. Bubbles
Air bubbles will affect delamination, and severe will lead to failure.
①The temperature parameter setting of the laminator at the time of vacuuming should be set in strict accordance with the process requirements.
②The welding and lamination process should pay attention to the cleanliness of the process 5s.
③The cutting size of the insulating strip is strictly required for cutting and viewing.
4. Cells are interspersed with hidden cracks
Interspersed cracks will form grain fragments and make the battery fail, and the power attenuation of the module will directly affect the function of the module.
①Strictly control the important parameters such as the temperature and time of the laminator, and do the crosslinking degree test regularly according to the requirements.
②Strengthen the improvement of raw material suppliers and the inspection of raw materials.
③Strengthen the appearance inspection of finished products during the manufacturing process.
④The gluing of the final assembly strictly requires the operation method, and the silicone needs to be completely sealed.
⑤When lifting and placing components, avoid being bumped by external force.
