Photovoltaic electricity production is an electricity production system.
Photovoltaics is a photovoltaic energy production system. It is a power generation system that uses the photovoltaic effect produced by semiconductor materials to convert the energy of solar radiation into electrical energy. The energy generated by the photovoltaic power generation system is a very safe, clean and renewable energy that will not harm the ecology or pollute the environment during the photovoltaic power generation process.
Photovoltaic power generation systems rely on solar energy to generate electricity, and current photovoltaic power generation systems can be divided into grid-connected and in independent photovoltaic systems.
The use of photovoltaic systems to produceeelectricity has many advantages, such as the ability to provide normal power supply in harsh weather conditions and environments, high safety performance and long service life. However, photovoltaic energy production also has many disadvantages: its initial investment cost is very high and technical training is necessary before its use.
1. Small power generation equipment
(1) Small power supplies ranging from 10 to 100 W are used by military and civilians in remote areas without electricity such as plateaus and islands. , pastoral areas and border posts. Household electricity, such as lighting, television, tape recorders, etc. ;
(2) 3-5KW rooftop grid-connected domestic power generation system;
(3) Photovoltaic water pump: dsolve problems in areas without electricity Deep wells for watering and irrigation.
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 system; rural operator telephone photovoltaic system, small communication machine, soldier GPS power supply, etc. .
4. Petroleum, marine and meteorological fields: cathodic protection solar energy systems for oil pipelines and tank valves, poweremergency and backup electrical equipment 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 plants: independent photovoltaic power plants from 10KW to 50MW, wind and solar (diesel) complementary power plants, various charging stations for large parking power plants, etc. 7. Solar buildings combine solar power generation with building materials to enable large-scale buildings to be electricity self-sufficient, which is a major development direction for the future.
