black, camouflage and brown (optional)


Military version and buckle whole design, convenient to surface of backpack, clothes and lamps


irradiance 1000W/m², AM in 1.5

Module temperature


Charge object

MP3, MP4, mobile phone, interphone, communication equipment, small power testing instruments, portable power supply, and radio

Suitable for consumer groups

gift, outdoor sports, cross country, portability and emergency purposes

Customized designs

labels, sizes, actual solar panel power, voltage, current and solar light impact strength ranges are accepted


Very thin, foldable, flexible, portable and lightweight easy to carry, waterproof design, PET produced, surface transparent and smooth film


Part 2 About Flexible Thin Film Solar Panel

1, Flexible solar panel structure


2, Product basic introduce

Good high Temperature and Low Light Performance

Limited Power Output Warranty no less than 80% at 25 years

Multiconductor connector or junction box

Shadow tolerance, bypass diodes Connected across every solar cell

Max system voltage 600VDC

Complies with IEC61646 standard.


3, Technology advantages

1) Zero discharge

2) No dangerous fuel stockage

3) No remove components

4) Silent Running

5) Zero breakage, low maintenance cost

6) Without manual operation

7) Without running cost

8) Long lifetime


4, Feature

1) Flexible (foldable): provide free design space for architects, and can connect with bending surface, meet the aesthetic requirement for BIPV

2) Lightweight: especially suitable for some installation surfaces is sensitive to weight.

3) Durable: polyester film encapsulated, ultraviolet resistant, moisture resistant, the application which over 10 years under extreme conditions have been proven by research, widely use for satellite, ocean, military various fields.

4) Without glass: Don’t breakage if stroked by hail, however, monocrystalline silicon or polycrystalline silicon solar modules stocked by hail, maybe need replacement solar modules, if so, will happen much cost. Also can walk on the flexible solar modules freely, it’s easy for installation and maintenance. 5) Shadow tolerance: good outside working performance under low light condition.

6) Superior performance under high light condition: 10%-20% higher power input than monocrystalline silicon or polycrystalline solar modules under high temperature.

7) Higher power generation.

8) Good self-cleaning: the surface has high pollution resistant, easy clean, climate resistant features, normally; dirt can be discharged clean by rain.

9) Easy to install


Part 3 About manufacturing

1, Manufacturing workshop

2, Manufacturing process

3, monolithic intergration

4, Manufacturing technology

1) Roll to roll without waste any precious resource.

2) Auto vacuum deposition technology—energy input is lower than Monocrystalline silicon and Polycrystalline Silicon solar module, it is high efficiency green environmental product.

3) Thin film technology---1/300 lower coating thickness than Monocrystalline silicon and Polycrystalline silicon solar modules, very save raw material.

4) 3-layer P-N conjunction technology—3-layer P-N conjunction of solar cell processing technology and can absorb not only the red spectrum as the crystalline solar cells but also the blue & green spectrums in the sunlights; .Very suitable on those areas with poor sunlight & still be with good power output even under the cloudy or rainy day.


Part 4 Difference between Flexible solar module and crystalline silicon solar module
