Solar energy has made significant progress in recent years, establishing itself as a significant participant in the energy business. One element that has aided in the advancement of solar energy’s performance and efficiency is the usage of ETFE as a protective covering for flexible solar panels. Discover why ETFE is the optimal solar panel protection coating by contacting TUMING Industrial (Shenzhen) Co. Ltd today.

ETFE is a popular coating technique for flexible solar panels. It is a highly malleable substance with outstanding mechanical qualities. ETFE flexible rubberized solar panels are extremely attractive, thin, and lightweight, and are ideal for outdoor use. Without a doubt, this cutting-edge technology is an advancement over the older and less expensive PET solar cell coating approach.

ETFE Characteristics

  • It features advanced technology back contact cells, which provide enhanced flexibility and wattage per square foot.
  • The frameless design is unique in that it incorporates six metal reinforced mounting holes for ease of installation.
  • Strict quality control to ensure compliance with the highest international standards CE and TUV certifications.
  • Flexible lamination material with a high transmittance is less prone to cracking than standard glass.
  • Outstanding electrical performance in settings with high temperatures and low light levels.
  • Both positive and negative leads have MC4 connections.
  • Two bypass diodes help to mitigate performance degradation caused by partial shadow.   
  • Product characterization
  • Electrical Measuring Instruments Under Standard Test Conditions

Components for ETFE Solar Panels

ETFE film- On the face of an ETFE solar panel, the outer protective coating is attached. This material is a replacement for the previously used PET coating substance.

EVA – (Ethyl-Vinyl Acetate)- A substance used to encapsulate solar cells that provide mechanical support and further environmental sealing. EVA allows for greater sunlight penetration without degrading.

Rubber strip- Protects the solar panel’s edges against delamination. To provide adequate protection, the rubber strip should be very resistant to heat.

Board of support- Typically made of fiberglass or aluminum, this is the primary component that gives the solar panel its ‘flexibility’. Fiberglass is a superior solar panel backing material to aluminum, but it is somewhat more expensive.

Photovoltaic cells- Solar cells harness solar energy and convert it to an electrical current. Monocrystalline, polycrystalline, or thin-film solar cells are all possible.

Grommets made of PV- Holes drilled into the corners of flexible solar panels for attachment. The majority of ETFE solar panels feature four grommets.

Photovoltaic connectors- Typically, these are MC4 connectors used to link all of your ETFE solar panels together. Because some flexible solar panels do not include MC4 connectors, you may need to purchase them separately.

ETFE Solar Panels Benefits

In the following table, we will observe ETFE solar panels is the best option for you:

MaintenanceThey require less care because they are self-cleaning.
Low-light performanceImproved performance due to their ability to be readily bent to maximize performance at various sun angles.
EfficiencyAppropriate efficiency.
DurabilityExtremely durable due to their reduced susceptibility to harm.
Life expectancyApproximately 10-15 years.
ApplicationThey are extremely versatile, as they may be used on curved surfaces as well.
The weight of a 100-watt moduleWeighs between 6 and 10 pounds, depending on the design.

Final Words

ETFE solar panels are lightweight, sturdy, and durable, making them the best power solution for home or outdoor activities. Buy ETFE solar panels from reputable manufacturers so that you’re assured of their quality. Cheap, low-quality ETFE modules from untrustworthy companies will die off after a few months of operation.
