PV module lamination increased the efficiency of solar panels. The protective layer used in lamination is typically made of ethylene vinyl acetate (EVA), a material that has been shown to improve the efficiency of solar panels by up to 2%.
Solar panel lamination is crucial to ensure the longevity of the solar cells of a module. As solar panels are exposed and subject to various climatic impact factors, the encapsulation of the solar cells through lamination is a crucial step in traditional solar PV module manufacturing.
The process of PV module lamination typically involves the use of a laminator machine. The solar cells and connecting wires are arranged in a specific pattern and placed between two layers of EVA film. This assembly is then passed through the laminator, which applies heat and pressure to fuse the layers, creating a solid and durable panel.
The most common way to laminate a PV module is by using a lamination machine, which applies heat and pressure to the module in a vacuum chamber. This process causes the EVA to melt and bond with the glass and TPT, forming a solid laminate.
Ready for lamination. During the lamination process, the prepared 5-layer module is placed in the lamination machine and heated to the max. 135°C for a period of approx. 22 minutes. The laminate that comes out is completely sealed, and when produced well, will protect the solar cells for at least 25 years.
