Description


Product Background
Solar 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.


Off-Grid Photovoltaic Power System
Off-Grid Solar Power Generation Systems Are Widely Used In Remote Mountainous Areas, Areas Without Electricity, Islands, Communication Base Stations, And Other Applications. The System Generally Consists Of A Photovoltaic Array Composed Of Solar Cell Components, A Solar Charge And Discharge Controller, A Battery Pack, An Off-Grid Inverter, A DC Load And An AC Load, Etc. The Photovoltaic Square Array Converts Solar Energy Into Electrical Energy Under The Condition Of Light, Supplies Power To The Load Through The Solar Charge And Discharge Controller, And Charges The Battery Pack At The Same Time; When There Is No Light, The Battery Pack Supplies Power To The DC Load Through The Solar Charge And Discharge Controller. At The Same Time, The Battery Should Directly Supply Power To The Independent Inverter, Which Will Be Converted Into AC Power Through The Independent Inverter To Supply Power To The AC Load.

 
Working Principle

The Working Principle Of Crystalline Silicon N/P-Type Solar Cells: When P-Type Semiconductors And N-Type Semiconductors Are Closely Combined And Connected Together, A P-N Junction Is Formed At The Interface Between The Two. When The Photovoltaic Cell Is Irradiated By Sunlight, The Accumulation Of Positive And Negative Charges Is Formed On Both Sides Of The P-N Junction, Resulting In A Photovoltaic Voltage And A Built-In Electric Field, Which Is The "Photovoltaic Effect". Theoretically Speaking, At This Time, If The Electrodes Are Drawn Out On Both Sides Of The Built-In Electric Field And Connected To An Appropriate Load, A Current Will Be Formed, And Power Will Be Obtained From The Load. A Solar Cell Module Is A Solid Device That Uses The Electronic Properties Of Semiconductor Materials To Achieve PV Conversion.
