In the 1960s, scientists had already applied solar cells to space technology, communications satellites. At the end of the last century, in the process of human self-examination, this kind of clean and direct form of energy for photovoltaic power generation has become more and more intimate, not only in space applications, but also in many fields. Such as: solar garden light, solar power household system, independent system of village power supply, photovoltaic water pump (water or irrigation), communication power, cathodic protection of oil pipeline, power supply of optical cable communication pump station, seawater desalination system, road sign in town, high speed Highway signposts, etc. Advanced countries such as Europe and the United States have integrated photovoltaic power generation into the urban power system and the remote villages' natural village power supply systems in the development direction. The integration of solar cells and building systems has become an industrial trend.
First, the user solar power
1. Small-sized power supplies ranging from 10-100W, used for power consumption in remote and non-powered areas such as the plateau, islands, pastoral areas, and border posts, such as lighting, television, and tape recorders;
2. 3-5KW family rooftop grid-connected power generation system;
3. Photovoltaic water pumps: Solving drinking and irrigation of deep water wells in areas where electricity is not available.
Second, traffic areas
Such as beacon lights, traffic / railway lights, traffic warning / sign lights, street lights, high altitude obstacle lights, highway / railway wireless telephone booths, unattended channel class power supply.
Third, communications / communications
Solar unattended microwave relay stations, fiber optic cable maintenance stations, radio/communication/paging power systems; rural carrier telephony photovoltaic systems, small communicators, soldier GPS power supplies, etc.
IV. Oil, Ocean and Meteorology
Cathodic protection solar power systems for petroleum pipelines and reservoirs, life and emergency power sources for oil drilling platforms, marine detection equipment, meteorological/hydrological observation equipment, etc.
Fifth, home lighting power
Such as garden lights, street lamps, portable lights, camping lights, mountaineering lights, fishing lights, black lights, tapping lights, energy-saving lamps.
VI. Photovoltaic Power Station
10KW-50MW independent photovoltaic power station, scenery (Chai) complementary power station, various large parking plant charging stations.
