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.

Lensun 80W ETFE Flexible Solar Panel Feature

1. Grade A PERC Monocrystalline solar cells with much higher efficiency and more durability than other mono solar cells.

2. 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.

3. ETFE film and fiberglass backboard can withstand extreme environmental conditions, maintenance-free for years.

4. Durable fiberglass substrate backboard, better heat dissipation than PET backboard which ensures a long lifetime

5. At only 2.5mm thick, the solar panel is powerful, waterproof, lightweight, durable, and highly resistant to the harsh operating conditions of a marine environment.

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

7.  Extreme curves, reverse curves, or uneven curves can damage the panels, so be sure to support the solar panel during installation and fitting into place. Do not bend the solar panel more than 20°.

8. Solar panel size and the junction box location can customize by customer request.

Why is ETFE superior?

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. The textures finish of ETFE solar panels makes them dirt-resistant and self-cleaning, minimizing the impact on solar output.

ETFE film is weatherproof and is also heat, fire resistance, corrosion, and UV resistant.

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.

Lensun® High Efficiency 20A MPPT 12V/24V Solar Panel Regulator Charge Controller LCD Display for Lead-acid, Lithium Solar system Battery Charging

Why we recommend buy MPPT Solar Controller?

   MPPT circuit solar controllers are considerably more elaborate than PWM. The MPPT technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature.

   The voltage of the solar panel changes with time of day and temperature. The optimum voltage for battery charging changes as the state of charge of the battery. The MPPT charge controller matches these voltages and can result in 30% more efficient transfer of power. This means good MPPT solar charge controllers can reduce the number of solar panels needed by up to 30%- a tremendous benefit.

   Another benefit of MPPT technology is a wide solar input voltage range - this controller can work not only with standard off-grid 12V/24V solar panels, but also with on-grid panels or solar panel arrays up to 150V. The maximum allowed input solar power for this controller is 260W (when charging 12V battery) or 520W (when charging 24V battery).

   This charge controller features a comprehensive set of electronic protection functions such as stopping reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection.

  Supporting charging procedures of Gel batteries, Sealed batteries, Open batteries, Lithium batteries and other types of batteries.
