The Feature

(1)They are hail-proof and shockproof, making them the perfect solar companion on the toughest Aussie tracks.
(2)They are 100% weatherproof, including the pre-wired (and bypassable) PWM solar controller mounted on the back of the panel, meaning you can leave them out no matter what the weather. (Note, we offer MPPT solar controller too, if you want to change to MPPT solar controller just contact us)
(3)They are constructed with stainless steel and aluminium fittings which means you never have to worry about rust.
(4)They feature a smart-magnet system to keep your panel closed without the need for bulky latches.
(5)They are constructed using a 1.2mm fibreglass, heat resistant PCB backing to ensure the solar panels remain strong and are resistant to sagging over time.


The Solar Cells

They have outstanding solar efficiency rating, up to 22+% thanks to the high quality A-Grade PERC Monocrystalline Solar Cells used

A High performance 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 22+%, generating more power per unit area. The conventional standard solar cell is only 18-19%.

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

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.



Made of high quality Black Fiberglass back sheet which is much lighter than the traditional glass back sheet. This material also combines better with ETFE film than plastic back sheet, which other panels frequently contain.

The Solar Controller

The included 20A Waterproof MPPT Solar Controller with anderson style plugs can be connected directly to AGM, Lead Acid, Gel & Calcium batteries.

The Extras

They come in a high quality, heavy duty carry bag with YKK zips.
They pack down smaller than most metal frame solar panels on the market and weigh over 50% less!
Here’s a quick weight comparison between each Super Thin model and their equivalent Glass Panel:

Traditional 300W Glass = 25kgs vs Lensun 300W Ultra Thin = 11kgs/24 lbs

Lensun Ultra Thin Solar Panel’s are highly durable, impact-resistant and shatterproof, making them the most heavy duty portable solar option on the market.
