ETFE Coated Reinforced Flexible Solar Panels

With an ETFE Coated Flexible Solar Panel can be use these in a number of ways. Flexibe can be used to charge various electronic devices, such as mobile phones and digital cameras, and people often use these options when working in remote locations to power their camping equipment, GPS, and communication systemsflexible

ETFE Coated Flexible solar panels are useful for applications like Motorhomes, Campers, Canal Boating, and outdoor activities like Camping or Walking where occasional power is needed. They’re typically used as an alternative to a conventional Rigid Solar Panels when the mounting locations are more complex, such as the curved roof of a Van or Caravan.

What is ETFE? 

Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer and its source-based name is poly(ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as ‘Teflon Film’. ETFE has a relatively high melting temperature and excellent chemical, electrical and high-energy radiation resistance properties.

Useful comparison tables of PTFE against FEPPFA and ETFE can be found on DuPont’s website, listing the mechanical, thermal, chemical and electrical properties of each, side by side. ETFE is effectively the high-strength version of the other three in this group.

ETFE film is self-cleaning (due to its nonstick properties) and recyclable. As a film for roofing it can be stretched and still be taut if some variation in size, such as that caused by thermal expansion, were to occur. Employing heat welding, tears can be repaired with a patch or multiple sheets assembled into larger panels.

ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of 89 K to 423 K (−185 °C to +150 °C or −300 °F to +300 °F).

ETFE resins are resistant to ultraviolet light. An artificial weathering test (comparable to 30 years’ exposure) produced no filtering and almost no signs of film deterioration.

ETFE systems can control light transmission through the application of plasma coatings, varnishes or printed frit patterns. Thermal and acoustic insulation can be incorporated into an ETFE structure via the use of multi-layer systems which use low-pressure air pumps to create ETFE “cushions”. For instance u value of ETFE single layer, double and three layers are approximately: 5.6, 2.5 and 1.9 W/m2.k respectively while concerning g value of etfe cushion or SHGC in ETFE systems it can vary between 0.2 to 0.95 using frits  and for further info about SHGC in ETFE refer to
