Half Cell High Efficiency PERC Solar Power Solar Panels 440W PV Modules
Key Features
1. Positive Power tolerance (0-5W) Guaranteed
2. High Module Conversion efficiency ( up to 20.3%)
3. Solar power degradation -- Enabled by low LID Mono PERC Technology: First year < 2%
4. Solid PID Resistance -- Ensured by solar cell process opitimization and careful module BOM Selection
5. Reduced Resistive -- loss with lower operating current
6. Higher energy yield--With lower operating temperature, high power performance
7. Reduced Hot Spot Risk -- With Optimized electrical design and lower operating current

PRODUCT INTRODUCTION:
Solar modules are composed of solar cells with high conversion efficiency,EVA sheet,soalr glass and Tedlar(TPT) back sheet compounded from fluoro-plastic and Dacron.The module adopts reliable welding technology and high-vacuum heating aluminum alloy frame and watertight terminal box.As a result,it takes on a rational structure,and has an ultraviolet aging resistance and wind resistance of up to 2400Mpa.
The mono-crystalline silicon solar module with the average conversion efficiency up to 21% which can work effectively even in the light dim. Meanwhile the module can increase the electricity energy greatly with anti-reflection film and high transparent glass. Backed with protective sheet. The cell can be protected properly with safety steel glass. Meanwhile the water is prevented from entering by using EVA and TPT. On the frame there are 4-6 holes for making easier to install on all the systems structure. In the joint box are 3 diodes which can effectively reduce the system power losing from the hidden module.
