During the time spent creating sunlight based boards, PV Z Profile Steel regularly experience different quality issues, which is the primary purpose behind the power lessening of photovoltaic modules during force age. Regular quality issues are:
1. The segments are secured by silica gel and EVA buildup isn’t cleaned set up, causing the bond of open air dust, which may make problem areas harm the parts.
2. Irrational cover or auxiliary overlay. The overlay temperature is excessively high, or the cover time is excessively long, and the part 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 assistant materials, for example, EVA and back sheet. The change will in the long run lead to a noteworthy drop in the power age of the module.
3. 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 extraordinarily decreased. The determination of cell makers is essential, and part makers ought to likewise be furnished with pertinent testing instruments, for example, EL sorters, EL analyzers, and so on., to decrease the issue of cell stream into the creation procedure.
4. Air pockets. There are evident air pockets in the segment. After long haul use, the air pocket zone increments and even makes a ceaseless air pocket channel, which will cause the part capacity to drop and inevitably cause the segment to be unusable.
5. virtual welding. The welding zone of the circuit inside the part is excessively little. Under the unforgiving climatic conditions, the association disappointment happens because of the impact of high and low temperature substituting, lastly the intensity of the module is significantly diminished.
6. battery film canister. The power and current binning of the battery in the part are conflicting, and the genuine yield intensity of the segment is excessively not quite the same as the hypothetical intensity of the segment. Conflicting binning will cause variations from the norm 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.
7. broken battery pieces. There is a shrouded cell in the module, and its capacity is marginally lower than that of the ordinary detail. In the long haul use process, the shrouded splits are heightened, making more zone be diminished from the part circuit and causing problem area impact. The parts are problem areas and even consumed.
8. Motion isn’t utilized appropriately. (1) Abuse of motion. There is more transition buildup on the outside of the battery. It isn’t treated before bundling. Consumption after epitome is anything but difficult to cause greening of the patch strip, increment segment opposition and decrease part control. Likewise, when the leftover motion has a little PH esteem, it might respond with the EVA to cause yellowing, bringing about an abatement in the intensity of the module. (2) When the battery is fastened, the motion is inappropriately utilized, making the EVA respond with the transition, framing a lot of white spots on the outside of the battery, and the intensity of the module is incredibly diminished.
