Solar photovoltaic (PV) power generation is a process of converting light energy directly into electric energy by using the photogenerating volt effect generated by semiconductor interface. The dc electricity generated by the generator is converted into AC electric energy through the inverter, which is boosted by the booster transformer station and then transmitted to the power grid. The electric energy is transmitted to the power terminal through the power grid transmission line. So, what are the application areas of solar photovoltaic power generation?
1, household solar power supply :(1) small power supply ranging from 10-100w, used for remote areas without electricity, such as plateau, islands, pastoral areas, border posts and other military and civilian life electricity, such as lighting, TV, radio recorder, etc.; (2) 3-5KW household roof grid-connected power generation system; (3) Photovoltaic water pump: to solve the deep water well drinking and irrigation in areas without electricity.
2. In the field of transportation, such as navigation lights, traffic/railway signal lights, traffic warning/sign lights, Yuxiang street lights, high altitude obstacle lights, highway/railway wireless telephone booths, unattended road class power supply, etc.
3, communication/communication field: solar unattended microwave relay station, optical cable maintenance station, broadcast/communication/paging power supply system; Rural carrier phone photovoltaic system, small communicator, GPS power supply for soldiers, etc.
4. Petroleum, Marine and meteorological fields: petroleum pipeline and reservoir gate cathodic protection solar power supply system, oil drilling platform living and emergency power supply, Marine testing equipment, meteorological/hydrological observation equipment, etc.
5, household lighting power supply: such as garden lamp, street lamp, hand lamp, camping lamp, hiking lamp, fishing lamp, black light, rubber cutting lamp, energy-saving lamp, etc.
6, photovoltaic power station: 10KW-50MW independent photovoltaic power station, scenery (firewood) complementary power station, various large parking plant charging station, etc.
7. Solar architecture will combine solar power generation with building materials, so that large buildings in the future can achieve self-sufficiency in electricity, which is a major development direction in the future.
8. Other fields include: (1) Supporting vehicles: solar cars/electric cars, battery charging equipment, automobile air conditioning, ventilation fans, cold drink boxes, etc.; (2) Solar hydrogen production and fuel cell regenerative power generation system; (3) Power supply for seawater desalination equipment; (4) Satellites, spacecraft, space solar power station, etc.
In recent years, photovoltaic power generation has developed rapidly in the world. More than 10 megawatt photovoltaic power generation systems and 6 megawatt networked photovoltaic power stations have been built in the world. Solar photovoltaic power generation in the near future will occupy an important seat in the world energy consumption, not only to replace part of the conventional energy, and will become the main body of the world energy supply.
