SGP Solar Film Production Machine For BIPV Modules

1. Machine model of SGP solar Film production machine

2. Comparison of SGP Solar film and EVA encapsulation film

EVA is a thermosetting resin with cross-linking reaction; SGP is a thermoplastic resin with reproducibility and no cross-linking reaction;

The domestic glass curtain wall specification clearly puts forward the requirement of "application of SGP". And BIPV photovoltaic modules using SGP instead of EVA can achieve a longer service life.

SGP has strong bonding performance and is safer than EVA film;

There are many formulas for EVA, and the packaging process is not easy to control; the formula for SGP solar film is simple, the quality control is stable, and the shelf life is long;

SGP solar film has poor fluidity, which can prevent film overflow during processing.

3. SGP Photovoltaic Encapsulation Film production machine introduction:

SGP solar film is mainly used for BIPV modules, the structure is tempered glass (super white)-SGP-cell-SGP-tempered glass (ordinary).

At present, the encapsulation forms of photovoltaic modules mainly include glass-EVA-backplane type and glass-SGP-glass type. I will elaborate on the SGP encapsulation film and SGP solar film production machine.

Photovoltaics is a rapidly developing emerging industry that converts solar energy into electrical energy. Among them, crystalline silicon solar cell modules are mainly used in large-scale grid-connected power generation, off-grid power stations, BIPV photovoltaic building integration, etc., and SGP encapsulation film production lines are mainly used in BIPV buildings,photovoltaic power generation components.

4. Introduction of SGP solar Film production machine

The SGP solar film production machine manufactured by GWELL adopts unique design and advanced manufacturing technology, which improves the stability and automation of the machine. The feeding system is connected with the extruder to realize the accurate online proportioning of raw materials, so that the quality of the SGP film is stable and labor cost will be reduced. Specially designed rollers are used to cool the SGP film uniformly and reduce the stress caused by uneven heating and cooling, thereby ensuring the correct shrinkage rate. Since the SGP film is relatively viscous, we have added an isolation film unwinding device to effectively prevent the SGP film from sticking together during rewinding.
