How to protect the photovoltaic power station components of common adverse phenomenon

Photovoltaic modules in the process of production inevitably there are some unhealthy phenomenon and problems, how to ensure the quality of components is higher and the percent of pass is each manufacturer issue of concern. Solar photovoltaic power station manufacturer for you below summarizes some components in the process of production easy

photovoltaic component production process will inevitably appear some bad phenomena and problems. How to ensure the quality of higher module and percent of pass is each manufacturer issue of concern. The solar photovoltaic power station manufacturer for you summarized the problems in the production of some components and solutions. First of all, the photovoltaic modules have fraction cause analysis: 1, as there is no welding during the welding process, there are a bunch of tin or tin slag, when extracting amount is empty, pieces of batteries will be crushed. 2. Due to premature galvanic dark wound and laminated, EVA has good liquidity. 3. Mentioned components, the position is not reasonable, hands on batteries. Solution: 1. First of all, should check the welding quality in welding area, and to strengthen the pertinence of staff training, in order to ensure a one-time welding. 2. Adjust the laminating process, increase the extracting time and reduce the empty layer pressure ( By laminating time adjusting) 。 3. Control of each link, and improve the effect of personnel quality, guarantee the correctness of the lift plate position. Second, the components of bubbles. Cause analysis: EVA film has been cut off, and placed a long time, and has set up a be affected with damp be affected with damp. EVA film material itself quality is not high, for example, some EVA manufacturer part or all of the use of domestic raw materials. 3 - Due to the storage time is too long or storage conditions, backplane solar energy will be affected with damp be affected with damp. 4 - Pumping vacuum is too short, pressurized air bubbles can not be expelled. 5 - Insufficient pressure laminate. 6 - The temperature of the heating plate is not uniform, resulting in local solidification in advance. 7 - Laminated time is too long or the temperature too high can produce oxygen decomposition of organic peroxides. 8 - There are foreign bodies, and the wetting Angle is greater than 90 °, so foreign body next to the existing gas. Solution: EVA number control use every day, make every employee know the daily production task. Material is determined by the manufacturer, so try to choose better material. 3 - Will cut solar energy back into the pre baked in the oven for 2 minutes, remove moisture. 4 - Adjust the laminating process parameters, make the finishing empty time is right. 5 - Increase the layer pressure. ( Time can be laminated to adjust or add another layer of high temperature cloth. ) 6 high temperature cloth, the components are heated evenly ( Large temperature difference is less than 4) 。 7 - According to the parameters given by manufacturers, determine the total laminated time, to avoid the time is too long. 8 - should be paid attention to 6 s management, especially in the process of laminating, as much as possible to avoid falling into foreign body. Three, component hairy and garbage cause analysis: due to static electricity exists in EVA, solar back ( Such as 3 m, mega) , small cars, etc. , the hair, dust and some small floating garbage is sucked into the surface. Folding, body above the components work, but cannot guarantee the body without the hair and rubbish. A few small flying insects, like mosquitoes, is struggling to drilling parts. Solution: to do a good job of 6 s management, maintain a clean and tidy working environment around, frequently wash clothes, trousers, do a good job in personal hygiene.
