LensunSolar 400W(2x200W) ETFE Black Flexible Solar Panel for RVs, Campers, Boats, Roof Top Tent, Cabin...etc. 

LensunSolar Flexible Solar Panel is an innovative and highly efficient solar panel. Its cutting-edge technology and advanced design make it a top choice for RVs, campers, boats, roof tents, and more.

Whether you're looking for a reliable source of energy for your RV, boat, or cabin, or simply want to reduce your reliance on traditional power sources, LensunSolar Flexible Solar Panel is a great choice. It's tough, durable, and highly efficient, making it the perfect solution for your energy needs.

LensunSolar flexible solar panels are made of PERC 9BB solar cells which is the most advanced and efficient available. With an impressive 23.5% efficiency, they deliver high power output in a compact form factor. The 9 busbar solar cell design reduces the risk of cell cracks and busbar damage, resulting in a more stable and reliable solar array.

Feature of PERC 9BB Monocrystalline solar cells

A High prmance solar cells is the decisive factor for top quality solar modules.

* First-rate efficiencies and excellent output consistency.

* The uniform color of the cell surface looks more beautiful.

* PERC is a good improvement on the conventional standard solar cell, density of energy increases and also ROI.

* Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.

* PERC solar cells component efficiency is as high as 23.5%, generating more power per unit area. The conventional standard solar cell is only 18-19%.

The 9BB(9-busbar) technology that optimizes electricity collection and ensures optimal electricity yield from your system. And 9BB technology better performance against crack than the other 2BB, 3BB or 4BB 5BB technology.

LensunSolar's flexible solar panel boasts a range of features that make it a top choice for those seeking a durable and high-performing solar panel

1. Durability: Our cutting-edge technology includes special materials to protect the solar cells from extreme weather conditions(extreme wind, packed snow and hail), ensuring panel longevity.

2. Solar cell: Made of Grade A PERC 9BB Monocrystalline solar cells with much higher efficiency (23.5%) and more durability than other mono solar cells.

3. Premium EFTE Film: This film features superior light transmittance and weatherproof performance, and is also heat, corrosion, and UV resistant. ETFE also has self-cleaning abilities, ensures the best performance day after day.

4. Shade Tolerant: Twin array design allows continued performance even with shading by trees or debris.

5. Backboard: Our solar panel features a durable fiberglass backboard with better heat dissipation and heat-resistant than PET/TPT board, ensuring a long lifetime in extreme environmental conditions.

6. Ultra-thin: At only 3mm thick, our solar panel is powerful, waterproof, lightweight, durable, and highly resistant to the harsh operating conditions of a marine environment.

7. Lightweight: Weigh approximately 30% of a glass framed one. They’re a great choice where you want big power without sacrificing fuel economy, or don’t want any extra weight on your roof that may affect your center of gravity.

8. Installation: Can be fixed by adhesive, grommets, zip ties, or velcro, and can be installed without costly structural roof reinforcements. Holes on panels are pre-drilled for fast mounting and securing, making it perfect for non-permanent installations.

Why is etfe superior?
1. ETFE solar panels have a better light penetration percentage of 95%. They contain fluorine atoms that bond to the panel's EVA, ensuring it will never delaminate or discolor as time pass.
2. The textures finish of ETFE solar panels makes them dirt-resistant and self-cleaning, minimizing the impact on solar output.
3. ETFE film is weatherproof and is also heat, fire resistance, corrosion, and UV resistant.
4. The age of ETFE laminated membrane is up to 25 years. Later can recycle it for other purposes, 100% recyclable.

Performance of ETFE vs. PET


ETFE (Ethylene Tetrafluoroethylene)

PET (Polyethylene terephthalate)


Ultra lightweight and durable. The combination between ETFE and back sheet is much stronger than PET.

Combination of PET and back sheet cracks easily, is not durable, and also not waterproof.


Includes a 0.025mm thin, UV resistant, layer of protection. Total thickness less than 0.1mm.

0.15mm thick. Solar cells break easily due to low hardness.

Light transmission

95% transparency offers excellent efficiency in terms of light to electricity conversion.

90% to 93% transparent results in lower efficiency in terms of light to electricity conversion.

Surface adhesion

ETFE has non-adhesive surface properties. Highly stain-resistant and easily gets cleaned by the rain.

Adhesive surface often gets covered with dust or other debris, significantly affecting the output of solar panel.


Lifetime of 10 years. Resists aging, deteriorates slowly.

Lifetime of at most 5 years. Easily forms air pockets and peels off.


Highly resistant to seawater corrosion.

Not acid and alkali resistant, making it totally unsuitable for use in marine environment.


Highly flame retardant. Suitable for use in temperatures ranging from -65°C to +150°C. Can be installed safely in hot climates.

Not suitable for use in high temperature regions due to short-term heat resistance.

Applicative effects

Absorbs sunlight. Does not reflect it.

Reflects a large amount of sunlight, producing glare and creating traffic risks to cars and airplanes.
