3W 6V Small Black Flexible Solar Panel with USB Interface Applied in Charging iPhone, Samsung mobiles


We can accept customize manufacturing flexible solar panel, if your quantity is suitable.



Flexible solar panel is use special high-end thin film technology. It is has more advantages than laminated solar panel, such as good performance in the high temperature and in the low light, light weight to be more suitable for buildings which are sensitive in weight. The most important feature of the flexible solar panel is can be flexible or foldable. This feature can give more space for architects to realize their colorful design.



The blue, green and red cell coatings can absorb the corresponding lights in the sunshine. The function of absorbing different light band is the key to increase the cell’s efficiency, especially in the low light and scattered light conditions.



Current (max.)500mA
Shadow ToleranceLoss (4%-5%)
Power Output WarrantyReduce not higher than 20% within 25 years
Low Light Performance20% higher generating capacity


This model flexible solar panel can charge the electronic devices directly, such as iPhone, Samsung, MP4, etc. Don't worry about the floating of the current from solar panel to demage the devices because there is a insert chip to make sure the current stable. 

It is very portable to take this panel out to charge your phone. No need to worry about your phone will powered off because this panel can charge your phone always if the place has sunshine.


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

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

>> 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.

>>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.

>>Shadow tolerance: good outside working performance under low light condition.

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

>>Higher power generation.

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

>>Easy to install




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.
