What is EVA delamination of solar photovoltaic modules?

As the power source of solar photovoltaic modules, several single cells must be connected in series, connected in parallel, and tightly sealed into modules. Solar photovoltaic modules (also called solar panels) are the core part of the solar power system and the most important part of the solar power system. The role of solar photovoltaic modules is to convert solar energy into electrical energy, or send it to storage batteries, or drive loads to work. So what is EVA delamination of solar photovoltaic modules? Let's take a look together next.

Here is the content list:

• Reasons for EVA delamination of solar photovoltaic modules

• The influence of EVA delamination of solar photovoltaic modules

• Preventive measures for EVA delamination of solar photovoltaic modules

Reasons for EVA delamination of solar photovoltaic modules

Due to the unqualified degree of EVA cross-linking of solar photovoltaic modules (such as the low temperature of laminator, short laminating time, etc.), EVA delamination is caused. Or, foreign matter on the surface of solar photovoltaic module raw materials such as EVA, glass, back sheet, etc., causes the EVA of the solar photovoltaic module to delaminate. The uneven composition of the EVA raw materials (such as ethylene and vinyl acetate) of the solar photovoltaic module leads to the inability to dissolve at normal temperature and causes the EVA to delaminate. Too much EVA flux is used for solar photovoltaic modules, and the EVA delamination of the solar photovoltaic modules on the main grid line occurs when exposed to high temperatures for a long time in the outside world.

The influence of EVA delamination of solar photovoltaic modules

When the EVA delamination area of the solar photovoltaic module is small, it will affect the high-power failure of the solar photovoltaic module. When the EVA delamination area of the solar photovoltaic module is large, it will directly lead to the failure of the module.

Preventive measures for EVA delamination of solar photovoltaic modules

The solar photovoltaic module EVA strictly controls important parameters such as the temperature and time of the laminator. In addition, the EVA of solar photovoltaic modules is regularly tested for the degree of cross-linking following the requirements, and the degree of cross-linking of the solar photovoltaic module EVA is controlled within 85% ± 5%. Solar photovoltaic module EVA strengthens the improvement of raw material suppliers and the inspection of raw materials. Strengthen the appearance inspection of finished products during the EVA manufacturing process of solar photovoltaic modules. Strictly control the amount of EVA delamination flux for solar photovoltaic modules, and try not to exceed 0.3mm on both sides of the main grid line.

The JF solar team of the manufacturer of Anhui JF Solar Technology Co., Ltd. (JF Solar) focuses on the production and development of solar photovoltaic modules with more than 12 years of rich experience. With advanced automatic production lines, JF Solar can provide a total of 2GW of high-efficiency solar modules each year. At the same time, as a system energy solution provider integrating clean energy development, construction, operation, and management. To reduce the EVA delamination of solar photovoltaic modules, a large number of tests are carried out before the solar photovoltaic modules leave the factory. Consumers provide quality assurance.
