Difference between ETFE laminate and Solar laminate?
ETFE is a fluorine-based polyethylene. It was engineered to exhibit excellent corrosion resistance and strength across a wide temperature range. ETFE is a polymer, and its source-based term is polyethylene terephthalate (ethene-co-tetrafluoroethene). It has a relatively high melting point and great resistance to chemicals, electricity, and high-energy radiation. When ETFE is burned, it produces hydrofluoric acid.
ETFE Laminate Characteristics
- Superior Efficiency- The efficiency ranges from 21% to 25%, whereas most monocrystalline panels achieve just 17% to 19% efficiency. You will achieve higher energy efficiency even though the panel is the same size as a conventional model.
- By combining ETFE lamination craftsmanship with thin-film flexible solar production technology, the same encapsulation technology may be used.
- Assuring solar panel durability by absorbing more light and surviving up to 15-25 years in outdoor circumstances.
- For ease of installation, this frameless design features four metal reinforced mounting holes (optional).
- The flexible plastic back sheet can be bent up to 30 degrees and mounted on an RV, boat, cabin, tent, or any other irregular surface, while the front ETFE layer provides additional protection and increases the solar panel’s endurance.
- CE Certification; 8-Year Product Warranty.
Solar Laminate
On the other hand, solar laminate strips are a cutting-edge product that is used in conjunction with roof systems.
This is a different type of integrated Solar technology. It is a flexible strip with an adhesive backing that sticks directly to the roof surface.
Specification & Benefits
The solar cell component of a strip is only 2.5mm in height (the junction box is 17mm in height but concealed) and is glued directly to the roof sheet’s pan. However, it also has considerable weight-saving, wind-resistant, and maintenance advantages.
Advantages
- In comparison to conventional solar modules that are put on a rail system above the highest point of the roof profile, this technique offers substantial benefits because the array becomes nearly undetectable on the roof. They are normally invisible from the ground on a low pitch roof, and even on a steeper pitch roof, they might be difficult to see when utilized on a dark-colored roof.
- The installation system conceals all wiring beneath the ridge or head barge flashing, resulting in no visible cabling, which enhances the product’s integrated appearance.
- Additionally, there is a desirable roof option for discerning architects and developers seeking to give a distinct aesthetic to their design. The result is a magnificent roof with the extra benefit of an integrated renewable energy source that does not detract from, but rather enhances the project’s overall beauty.
Final Word
Ethylene tetrafluoroethylene (ETFE) laminate is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. The efficiency can be up to 21%-25%, while the most monocrystalline panel is only 17%-19%. You will get greater power efficiency even though the panel is no larger than a traditional model.
On the other hand, Solar laminate strips are a very innovative product that are used to complement roof systems. The technology makes the array virtually invisible on the roof in contrast to conventional solar modules that are mounted on a rail system atop the highest point of the roof profile. The installation system also conceals all cabling beneath the ridge or head barge flashing, so there is no cabling visible which complements the integrated aspect of the product.
