18650 battery 3500mah lithium

　　What are the advantages and applications of photovoltaic cells?

　　Photovoltaic cells have no risk of depletion, are absolutely clean, are not restricted by resource distribution areas, can generate electricity close to where electricity is used, and have high energy quality. They are widely used in user solar power, transportation, communications/communications, etc., as detailed below Introduce "Advantages and Applications of Photovoltaic Cells".

　　1. Advantages of photovoltaic cells

　　1. No risk of depletion;

　　2. Absolutely clean (no pollution, except for batteries);

　　3. Not restricted by the geographical distribution of resources;

　　4. It can generate electricity close to where it is used, and the energy quality is high;

　　5. It is easy for users to accept it emotionally;

　　6. It takes a short time to obtain energy;

　　7. The power supply system works reliably.

　　2. Application of photovoltaic cells

　　1. User solar power supply

　　Small power supplies ranging from 10-100W are used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, and border posts, such as lighting, TVs, radios, etc.; 3-5KW household rooftop grid-connected power generation systems; photovoltaic water pumps, Solve the problem of deep water well drinking and irrigation in areas without electricity.

　　2. Transportation field

　　Such as navigation beacon lights, traffic/railway signal lights, traffic warning/sign lights, street lights, high-altitude obstacle lights, highway/railway wireless phone booths, unattended road shift power supply, etc.

　　3. Communication/communication field

　　Solar unattended microwave relay station, optical cable maintenance station, broadcast/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.

　　4. Petroleum, ocean, and meteorological fields

　　Petroleum pipelines and reservoir gate cathodic protection solar power systems, oil drilling platform life and emergency power supplies, ocean detection equipment, meteorological/hydrological observation equipment, etc.

　　5. Home lighting power supply

　　Such as garden lights, street lights, portable lights, camping lights, mountaineering lights, fishing lights, black light lights, rubber tapping lights, energy-saving lamps, etc.

　　6. Photovoltaic power station

　　10KW-50MW independent photovoltaic power stations, wind and solar (diesel) complementary power stations, various large parking plant charging stations, etc.
