With EVA film
Reflective film needs to be used with solder tape and EVA to achieve the best performance:
The match is as follows:
Reflective Film (0.12mm Thickness)-Welding Tape (0.25mm Thickness)-EVA 600 g / m2
60 modules can increase power by 4.5W on average, and increase output by about 1.8%;
The above collocation is an experience collocation after scale application, please refer to it for reference.
Storage conditions
1. Temperature: 5 ~ 30 ° C, relative humidity:<60%;
2. Please use up as soon as possible after unpacking to avoid being eroded by water vapor; wear gloves to operate reflective film to prevent damage and pollution to the film surface;
3. In the unopened state, the shelf life is 6 months from the date of production.
product structure
Structure: generally consists of a four-story structure
1. Substrate layer: PET layer, imported optical grade low shrink film;
2. Adhesive layer: hot melt adhesive resin, imported raw materials;
3. Prism structure: apex angle is 120 °;
4. Reflective layer: alloy coating, multiple metal composite coatings, good adhesion and weather resistance.
Surface texture: The unique S-shape texture is used to effectively improve the light utilization efficiency and increase the total power generation of the module.
