Why CIGS solar? Light weight Can be used on structures and roofs that can't support glass module installations Flexible, thin Can be used on curved roofs and surfaces Wind Resistant, waterproof Great for high wind areas, as their flat installation does not increase the wind load Lower Installation Costs The lack of racking (and penetrations), and easy "peel and stick" installation lowers material and labor costs of installation. Shade Resistant Outperforms c-Si modules in partially shady conditions Theft Resistant Virtually eliminates theft of modules in high crime areas Durable and Tough Largely eliminates issues of vandalism or damage from micro cracks as a result of foot traffic or vibration Custom solutions DINGHUI offer Customized sizes, color, and Customized design for outdoor, military application. • Dimension: 52 x 32 x 17cm • Capacity:25L • Structure:Notebook bag, pack bag, assorted luggage • Applications :outdoor, leisure ,traveling,hiking • Color:Sky-blue, light purple, stone grey, black. • Material: Polyester fiber Specifications: 1. High efficiency thin film solar cell imported from US CIGS flexible cell. 2. The size of battery module is smaller than backpack. 3.When it is not charging, battery module can be put in the pack bag. 4. Battery module can be separated from backpack. Characteristics: 1. Smart dual USB output; 2. Stable 5V DC output; 3. Broad compatibility: it can support most mobile electronic device on the market. User manual: 1. Face the solar portion to the sun, and when LED light is on, then you can start charging 2. Stretch mesh bag: it can put phone, Pad, etc. 3.When you are hiking, riding and doing other outdoor sports, solar panels can be placed on the outside of the package, when LED lights, it can be used to recharge electronic devices. Notes: • Solar power generation is most efficient when directly exposed to the sun. Indoor or in car conditions can be affected by the window/film which has cut off certain wavelength of sun light resulting in less power generation. • The performance will be affected by season, weather, ambient temperature, angle to the sun, shadow area and some other nature factors. To obtain the best sunlight collection efficiency, please angle the module towards the sun. • The performance can be severely affected by sunlight intensity, radiation angle, cloud, shadow of tree, overpasses, elevated highways, buildings, etc. It is much preferred to charge the power bank directly, then charge portable electronic devices with power bank. • Some phones charged with solar module might show pop-up message of "DO NOT SUPPORT THIS DEIVCE". Please charge the power bank first. • Do not use the solar module when relative humidity is higher than 80%, or surface temperature is higher than 80ºC. • Keep the solar module surface NO RESIDUE, NO BLOCKING, NO SHADOW, NO SCRATCH.
