Which 9 fields can solar off-grid system be applied to？

Because thermal power needs to burn coal, oil and other fossil fuels, on the one hand, fossil fuel reserves are limited, is facing the risk of exhaustion.  On the other hand, burning fuel will emit CO2 and sulfur oxides, which will lead to the greenhouse effect and acid rain, worsening the earth's environment.  Hydropower has to flood large amounts of land, potentially causing ecological damage, and the collapse of large reservoirs can have disastrous consequences. In some countries, water resources are also limited and seasonal.  Nuclear power is clean under normal circumstances, but the consequences of a leak are equally dire.  
 
With the rapid development of global economy and the progress of human beings, people have put forward higher and higher requirements for energy. The development of new energy has become an urgent task facing human beings at present.  Solar power generation is the use of solar energy and semiconductor materials to achieve the electrical characteristics of electricity generation.  Which 9 fields can solar off-grid system be applied to？
 
1, user solar power supply: 10-100W solar off-grid system, 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.;  3-5kW household off-grid solar system system;  Photovoltaic solar water pump: solve the deep water well drinking and irrigation in the area 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, outdoor camping, picnic electricity, use portable power station

 
9.Other fields include: Supporting vehicles: solar cars/electric cars, battery charging equipment, automobile air conditioning, ventilation fans, cold drink boxes, etc.;  Solar hydrogen production and fuel cell regenerative power generation system;  Power supply for seawater desalination equipment;  (4) Satellites, spacecraft, space solar power station, etc.
