What are the areas of application of solar cells?

Answer: (1) User solar power supply: ——Small power supply ranging from 10 to 100 W, used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc. , such as lighting, televisions, radios, etc. ——3-5 kW domestic rooftop grid-connected power generation system. ——Photovoltaic water pump: solves the problem of watering and irrigating deep water wells in areas without electricity. (2) Transportation field: such as navigation beacon lights, road/railroad signal lights, warning/signal lights, street lights, high-altitude obstacle lights, cordless telephone booths for highways/railways, unattended route changing power supply, etc. (3) Communication/communication field: solar micro relay stationunattended waves, optical cable maintenance station, broadcast/communication/call power system; rural operator telephone photovoltaic system, small communication machine, soldier GPS power supply, etc. (4) Oil, ocean and weather fields: cathodic protected solar power systems for oil pipelines and reservoir valves, life and emergency power supplies for oil drilling platforms, ocean sensing equipment , meteorological/hydrological observation equipment, etc. (5) Power supply for home lighting: such as garden lights, street lights, portable lights, camping lights, climbing lights, fishing lights, black light lights, LED lights rubber tapping, energy saving lamps, etc. (6) Photovoltaic power plants: independent photovoltaic power plantsntes from 10 kW to 50 MW, complementary wind and solar (diesel) power plants, various large charging stations for parking lots, etc. (7) Solar buildings: Combining solar power generation with building materials will make future large buildings self-sufficient in electricity, which is a major development direction for the future. (8) Other fields include: ——Automotive accessories: solar vehicles/electric vehicles, battery charging equipment, automobile air conditioners, fans, cold drink boxes, etc. ——Solar hydrogen production and fuel cell regenerative energy production system. ——Power supply for seawater desalination equipment. ——Satellites, spacecraft, space solar power plants, etc.
