Ningbo Joanwin Int'l Co., Ltd.

We are an export specialist in environmental protection products, dedicated to integrated business of research, production, sales and service. Our main products include a series of solar chargers, solar camping lights, solar flashlights, solar bike lights, solar head lamps, solar book lamps, LED camping lights, multi-energy supply camping lights, LED head lamps, LED bike lights, LED flashlights and LED work lamps as well as other low consumption, environmental protection products. Our annual sales range from $10 million to $12 million, 20% of which would be invested in new products development each year. We have a research team of vigorous young members, led by two British designers graduating from Central Saint Martins College of Art and Design. The flexible solar charger, an emerging high-tech product, was introduced by us back in 2009 and won significant encouragement and support from our local government. It is capable of power supply for field work, due to its many features including high portability (amorphous silicon is one fifth of the weight of crystalline silicon of the same watts and unit), foldability and extensibility, corrosion resistance, high and low temperature resistance (up to 80C and down to -40C), ageing resistance (up to over 20 years), insulation, water and moisture proof, as well as our flexible customized power allocation service ranging from 1.5W to 64.0W or even higher levels. On top of that, the flexible amorphous solar cell is a three-layer composite technology of P-N sandwich structure, absorbing red, blue and green spectrums in three layers from the sunlight, which has resolved the limitation of monocrystalline and polycrystalline silicon for only absorbing visible low frequency red wave spectrums. Surface treatment on its encapsulation greatly reduces the impact of light mirror reflection, leaving more room for sunlight absorption. Meanwhile, we have also developed proprietary polymer cell encapsulation technology, which not only eliminates the aging of amorphous silicon but also extends its lifespan to 15 to 20 years. Nowadays, we have established production and sales business of flexible foldable solar chargers in US, Europe, Australia, Canada and other countries.
