The power constriction of photovoltaic modules

During the time spent delivering sunlight based boards, Steel C Proflle producers regularly experience different quality issues, which is the fundamental purpose behind the power constriction of photovoltaic modules during force age. Regular quality z section steel issues are:

1. The segments are secured by silica gel and EVA buildup isn’t cleaned set up, causing the grip of open air dust, which may make problem areas harm the segments.

2. Preposterous overlay or optional cover. The cover temperature is excessively high, or the overlay time is excessively long, and the segment is fixed and re-overlaid. After the high temperature of the segment, the EVA yellowing maturing coefficient is expanded. In the event that it is utilized outside for quite a while, it will be yellow in the helper materials, for example, EVA and back sheet. The change will in the end lead to a huge drop in the power age of the module.

3. Air pockets. There are clear rises in the part. After long haul use, the air pocket region increments and even makes a nonstop air pocket channel, which will cause the segment capacity to drop and inevitably cause the segment to be unusable.

4. virtual welding. The welding zone of ​​the circuit inside the segment is excessively little. Under the unforgiving climatic conditions, the association disappointment happens because of the impact of high and low temperature exchanging, lastly the intensity of the module is incredibly diminished.

5. battery film canister. The power and current binning of the battery in the segment are conflicting, and the real yield intensity of the part is excessively not quite the same as the hypothetical intensity of the segment. Conflicting binning will cause irregularities in the electrical exhibition test bend of the part, causing a hot plate impact, which will extraordinarily diminish the segment control for quite a while.

6. There are imperfections or contamination inside the battery when it is chosen. The imperfection of the battery will be uncovered in the long time of utilization, and the intensity of the part is enormously diminished. The determination of cell makers is urgent, and part makers ought to likewise be outfitted with pertinent testing instruments, for example, EL sorters, EL analyzers, and so on., to diminish the issue of cell stream into the generation procedure.

7. split battery pieces. There is a concealed cell in the module, and its capacity is somewhat lower than that of the ordinary detail. In the long haul use process, the shrouded splits are heightened, making more region be decreased from the segment circuit and causing problem area impact. The segments are problem areas and even consumed.

8. Motion isn’t utilized appropriately. (1) Abuse of transition. There is more motion buildup on the outside of the battery. It isn’t treated before bundling. Erosion after embodiment is anything but difficult to cause greening of the weld lace, increment segment obstruction and decrease segment control. What’s more, when the lingering motion has a little PH esteem, it might respond with the EVA to cause yellowing, bringing about a reduction in the intensity of the module. (2) When the battery is bound, the motion is inappropriately utilized, making the EVA respond with the transition, shaping a lot of white spots on the outside of the battery, and the intensity of the module is enormously diminished.
