If the photovoltaic power supply system is divided more carefully according to the application form, application scale, and load type of the solar photovoltaic system. Photovoltaic systems can also be subdivided into the following six types: small solar power supply system (Small DC); simple DC system (Simple DC); large solar power supply system (Large DC); AC and DC power supply system (AC/DC); Grid-connected system (Utility Grid Connect); hybrid power supply system (Hybrid).

Photovoltaic panels are power generation components. The photovoltaic controller regulates and controls the generated power. On the one hand, it sends the adjusted energy to the DC load or AC load, and on the other hand, it sends the excess energy to the battery bank for storage. When the generated power cannot meet the load needs At this time, the controller sends the battery energy to the load. After the battery is fully charged, the controller must control the battery from being overcharged. When the electric energy stored in the battery is discharged, the controller should control the battery from being over-discharged and protect the battery. When the performance of the controller is not good, it will have a great impact on the service life of the battery and ultimately affect the reliability of the system. The task of the battery is to store energy to ensure the load has electricity at night or on rainy days. The inverter is responsible for converting DC power into AC power for use by AC loads.

Sunlight shines on the p-n junction of the semiconductor, forming new hole-electron pairs. Under the action of the electric field of the p-n junction, holes flow from the n region to the p region, and electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photovoltaic effect solar cells work.

1. Photovoltaic power generation method There are two ways of solar power generation, one is the light-heat-electricity conversion method, and the other is the light-electricity direct conversion method.

(1) The light-heat-electricity conversion method generates electricity by utilizing the thermal energy generated by solar radiation. Generally, a solar collector converts the absorbed thermal energy into steam as a working fluid, and then drives a steam turbine to generate electricity. The former process is a light-heat conversion process; the latter process is a heat-electricity conversion process, which is the same as ordinary thermal power generation. The disadvantages of solar thermal power generation are that the efficiency is very low and the cost is high. It is estimated that its investment is at least higher than that of ordinary thermal power generation. Power stations are 5 to 10 times more expensive.

(2) Light-to-electricity direct conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for light-to-electricity conversion is the solar cell. A solar cell is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode converts the sun's light energy into electrical energy, producing current. When many batteries are connected in series or parallel, a solar cell array with relatively large output power can be formed. Solar cells are a promising new power source with the three major advantages of permanence, cleanliness and flexibility. Solar cells have a long life and can be invested once and used for a long time as long as the sun exists; they are different from thermal power generation and nuclear power generation. In comparison, solar cells do not cause environmental pollution.

1. User solar power supply: (1) Small power supply ranging from 10-100W, used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc., such as lighting, televisions, radio cassette players, etc.; (2) 3 -5KW household rooftop grid-connected power generation system; (3) Photovoltaic water pump: solve the problem of deep water well drinking and irrigation in areas without electricity.

2. Transportation field: such as navigation beacon lights, traffic/railway signal lights, traffic warning/sign lights, Yuxiang street lights, high-altitude obstacle lights, highway/railway wireless phone booths, unattended road shift power supply, etc.

3. Communication/communication field: solar unattended microwave relay station, optical cable maintenance station, broadcast/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.

4. Petroleum, ocean, and meteorological fields: cathodic protection solar power systems for oil pipelines and reservoir gates, life and emergency power supplies for oil drilling platforms, ocean detection equipment, meteorological/hydrological observation equipment, etc.

5. Power supply for household 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 stations: 10KW-50MW independent photovoltaic power stations, wind and solar (diesel) complementary power stations, various large parking plant charging stations, etc.

7. Solar buildings: Combining solar power generation with building materials will make future large-scale buildings self-sufficient in electricity, which is a major development direction in the future.

8. Other fields include: (1) Supporting automobiles: solar vehicles/electric vehicles, battery charging equipment, automobile air conditioners, ventilation fans, cold drink boxes, etc.; (2) Regenerative power generation systems for solar hydrogen production and fuel cells; (3) Seawater Power supply for desalination equipment; (4) Satellites, space crafts, space solar power stations, etc.
