What are the application fields of solar photovoltaic systems?
Traditional fuel energy is declining day by day, and the harm to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world has turned its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention with its unique advantages.
Abundant solar radiation energy is an important energy source. It is an inexhaustible, pollution-free, cheap, and freely available energy source for humans. The energy of solar energy reaching the ground per second is as high as 800,000 kilowatts. If 0.1% of the solar energy on the earth’s surface is converted into electrical energy, the conversion rate is 5%, and the annual power generation can reach 5.6×1012 kilowatt hours, which is equivalent to the world’s energy. 40 times the consumption. Next, let's see where are the application areas of solar photovoltaic power generation systems.
1. Traffic field: such as LED navigation lights, traffic/railway signal lights, traffic warning/sign lights, high-altitude obstruction lights, highway/railway wireless telephone booths, power supply for unattended road squads, etc.
2. User solar power:
(1) Small power supplies ranging from 10 to 100W, used in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc. for military and civilian life, such as lighting (including solar LED street light and other solar led lights), TV, radio cassette recorders, etc.;
(2) 3 －5KW home roof grid-connected power generation system;
(3) Photovoltaic water pump: solve the problem of drinking and irrigation in deep water wells in areas without electricity.
3. Petroleum, marine and meteorological fields: cathodic protection solar power systems for oil pipelines and reservoir gates, life and emergency power supplies for oil rigs, marine testing equipment, meteorological/hydrological observation equipment, etc.
4. Communication/communication field: solar unattended microwave relay station, optical cable maintenance station, broadcasting/communication/paging power system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.
5. Photovoltaic power stations: 10KW-50MW independent photovoltaic power stations, wind-solar (diesel) complementary power stations, charging stations for various large parking plants, etc.
6. Power supply for household lamps: such as garden LED lamps, LED street lamps, portable lamps, camping lamps, climbing lamps, fishing lamps, black light lamps, tapping lamps, energy-saving lamps LED, etc.
7. Solar energy building: Combining solar power generation with building materials to make future large-scale buildings realize power self-sufficiency is a major development direction in the future.
8. Other fields include:
(1) Supporting vehicles: solar cars/electric cars, battery charging equipment, car air conditioners, ventilators, cold drink boxes, etc.;
(2) Solar hydrogen production and fuel cell regenerative power generation systems;
(3) Sea water Desalination of equipment power supply;
(4) Satellites, spacecraft, space solar power stations, etc.
