What are the characteristics of solar photovoltaic power generation? First, photovoltaic power is based on the principle of photogenerated volt effect, using solar cells to convert solar energy directly into electrical energy. Photovoltaic power generation system is composed of three main parts, solar panels (components), controllers and inverters, which are mainly composed of electronic components, but do not involve mechanical components.

Therefore, photovoltaic power generation equipment is extremely refined, reliable, stable and long life, easy installation and maintenance. In theory, photovoltaic power generation technology can be used for any power supply, from the spacecraft to the spacecraft, to the home power supply, large to megawatt power stations, small to toys, photovoltaic power can be everywhere.

The composition and function of solar photovoltaic power generation system

The solar photovoltaic system consists of solar cells, solar controllers and batteries. If the output power is AC 220V or 110V, the inverter should also be configured. The functions of each part are as follows:

1. solar panels: solar panels are the core part of the solar power system and the most valuable part of the solar power system. Its function is to convert the solar radiation capability into electrical energy, or to store it in the battery or to drive the load.

2. solar controller: the function of the solar controller is to control the working state of the whole system, and play the role of overcharge protection and over discharge protection for the battery. In a larger temperature range, the qualified controller should also have the function of temperature compensation. Other additional functions, such as optical switch and time control switch, should be controller options.

3. batteries: generally lead-acid batteries, small and micro systems, but also nickel hydrogen batteries, nickel cadmium batteries or lithium batteries. Its function is to store the electricity generated by the solar panel when it is illuminated and release it again when it is needed.

4. inverter: the direct output of solar energy is usually 12VDC, 24VDC and 48VDC. In order to provide electrical energy to 220VAC electric appliances, it is necessary to convert the DC power generated by the solar power generation system into alternating current energy, so the DC-AC inverter is needed.


What are the characteristics of solar photovoltaic power generation?

1, no rotating parts, no noise;

2. No air pollution and no discharge of waste water;

3. There is no combustion process and no fuel is needed.

4. The maintenance and maintenance is simple and the maintenance cost is low.

5. It is reliable and stable.

6, as the key components of the solar cell long life, crystalline silicon solar cell life can reach more than 25 years.

7, it is easy to expand the scale of power generation according to the need.

The application of solar photovoltaic system is very extensive. The basic form of PV system application can be divided into two categories: independent power generation system and grid connected power generation system. The main applications include power supply in space, communication system, microwave relay station, TV differential platform, photovoltaic water pump and power shortage area.

With the development of technology and the need of sustainable development of the world economy, the developed countries have begun to popularize the urban photovoltaic grid connected power generation, mainly building the roof PV system and the MW centralized large grid connected power generation system. Meanwhile, the solar photovoltaic power generation is vigorously promoted in the transportation tools and urban illumination. The application of the system.
