The use of solar energy is mainly divided into several aspects: small household solar power plants, large-scale grid-connected power plants, building-integrated photovoltaic glass curtain walls, Yuxiang solar street lights , wind-solar systems. complementary street lights, wind-solar complementary power systems, etc., mainly the application methods are building integration and wind and solar complementary systems. 1. Solar energy is inexhaustible. The energy from solar radiation received by the Earth's surface can meet 10,000 times the global energy demand. As long as solar photovoltaic systems are installed in 4% of the world's deserts, the electricity produced will be able to meet the world's needs. Solar power generation is safe and reliable and will not be affected by energy crises or market instability.s fuels;
2. Solar power can be used anywhere and can provide power nearby without having to transmit it over long distances. avoid loss of long distance transmission lines;
3. Solar energy does not require fuel and the operating cost is very low;
4. , is not easy to damage and is simple to maintain, especially suitable for use in unattended conditions;
5. Solar power generation produces no waste, pollution, noise or other public hazards; and has no negative effects on the environment. It is an ideal clean energy source;
6. Construction of solar power generation system The cycle is short, convenient and flexible, and the quantity of solar panels can be added. or reduced at will depending on the increase or decrease in load to avoid waste. 1. The appation on the ground is intermittent and random, and the production of electricity is linked to climatic conditions. It cannot or rarely produces electricity at night or on rainy days
2. , energy production on the ground The intensity of the solar radiation received is 1,000 W/M^2. When used on a large scale, a larger area must be occupied;
3. The price is still relatively expensive, 3 to 15 times that of conventional electricity generation, and the initial investment is high.
1. User solar power: (1) Small power supply ranging from 10 to 100 W, used for military and civilian life in remote areas without electricity, such as plateaus and islands. , pastoral areas, border posts, etc. Electricity, such as lighting, television, radio, etc. ; (2) 3-5KW Household Rooftop Grid Connected Power Generation System (3) Photovoltaic Water Pump : solve the deep water problem; drinking water wells and irrigation in areas without electricity.
2. Transportation fields such as navigation beacon lights, road/railroad signal lights, warning/signal lights, Yuxiang street lights, high-altitude obstacle lights, highway/wireless telephone booths railways, power shifting without supervision. supply, etc
3. Communication/communication field: unattended solar microwave relay station, optical cable maintenance station, broadcast/communication/messaging power supply system; rural operator telephone photovoltaic system, small communication machine, soldier GPS power supply, etc. .
4. Petroleum, marine and meteorological fields: cathodic protection solar power systems for oil pipelines and tank valves, alemergency and back-up power supplies for oil drilling platforms, ocean sensing equipment, weather/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, rubber tapping lights, energy saving lamps, etc.
6. Photovoltaic power plant: Independent photovoltaic power plant from 10KW to 50MW, wind and solar (diesel) complementary power plants, various charging stations for large parking lots, etc.
7. Solar buildings combine solar power generation with building materials to make large buildings self-sufficient in electricity, which is a major development direction for the future.
8. Other areas include: (1) Supportautomobile: solar cars/electric cars, battery charging equipment, car air conditioners, fans, cold drink boxes, etc. (2) Solar hydrogen regeneration; production and fuel cells Energy production system; (3) Power supply for seawater desalination equipment (4) Satellites, spacecraft, space solar power plants, etc.
