Product BackgroundSolar Energy: The Sun Is A Huge Energy Source. It Emits About 3.8×10MW Of Energy Into Space Every Second In The Form Of Light Radiation, And One Part Of 2.2 Billion Is Projected On The Earth. After The Sunlight Is Reflected And Absorbed By The Atmosphere, 70% Is Transmitted To The Ground. Nevertheless, The Solar Energy Received By The Earth In A Year Is Still As High As 1.8×10KW·H. Since The Formation Of The Earth, Organisms Have Mainly Survived On The Heat And Light Provided By The Sun. Since Ancient Times, Humans Have Also been Known To Use Sunlight To Dry Objects And Use It As A Method Of Preserving Food, Such As Making Salt And Drying Salted Fish. But With The Reduction Of Fossil Fuels, There Is An Intention To Further Develop Solar Energy. There Are Two Ways To Utilize Solar Energy: Passive Utilization (Photothermal Conversion) And Photoelectric Conversion. Solar Power Is An Emerging Renewable Energy Source. In A Broad Sense, Solar Energy Is The Source Of Many Energies On The Earth, Such As Wind Energy, Chemical Energy, Potential Energy Of Water, And So On.Polycrystalline Solar PanelPolycrystalline Silicon Solar Cells Are A New Generation Of Solar Cells With The Advantages Of High Conversion Efficiency And Long Life Of Monocrystalline Silicon Cells And Relatively Simplified Material Preparation Process Of Amorphous Silicon Thin Film Cells. The Conversion Efficiency Is Generally About 17-18%, Slightly Lower Than That Of Monocrystalline Silicon Solar Cells Crystalline Silicon Solar Cells Have No Obvious Efficiency Degradation Problem, And It Is Possible To Prepare Them On Cheap Substrate Materials. Their Cost Is Much Lower Than That Of Monocrystalline Silicon Cells, And Their Efficiency Is Higher Than That Of Amorphous Silicon Thin Film Cells..
Working PrinciplePhotovoltaic Power Generation Is A Technology That Directly Converts Light Energy Into Electrical Energy By Using The Photovoltaic Effect At The Semiconductor Interface. The Key Element Of This Technology Is The Solar Cell. The Solar Cells Are Packaged And Protected After Being Connected In Series To Form A Large-Area Solar Cell Module, And Then Cooperate With Power Controllers And Other Components To Form A Photovoltaic Power Generation Device. The Advantage Of Photovoltaic Power Generation Is That It Is Less Restricted By Region, Because The Sun Shines On The Earth; Photovoltaic System Also Has The Advantages Of Safety, Reliability, No Noise, Low Pollution, No Need To Consume Fuel, And Erect Transmission Lines To Generate Electricity And Supply Power On Site, And The Advantages Of Short Construction Period.Advantage- Multi Busbar Technology Better light trapping and current collection to improve module power output and reliability. - Reduced Hot Spot Loss Optimized electrical design and lower operating current for reduced hot spot loss and better temperature coefficient. - PID Resistance Excellent Anti-PID performance guarantee via optimized mass-production process and materials control. - High Salt Mist and Ammonia Resistance. Enhanced Mechanical Load Certified to withstand: wind load (2400 Pascal) and snow load (5400 Pascal). Certificate - Certified by SGS, TUV, CE, CQC
Common ClassificationCrystalline Silicon Solar Panels: Polycrystalline Silicon Solar Cells, Monocrystalline Silicon Solar Cells.Amorphous Silicon Panels: Thin-Film Solar Cells, Organic Solar Cells.Chemical Dye Cells: Dye-Sensitized Solar Cells.Product Parameters
