What is photovoltaic power generation? What is distributed photovoltaic power generation?

Photovoltaic power generation has developed rapidly. The main power generation method of photovoltaic is that solar panels convert light energy into electrical energy, which is mainly used in life and industry. Photovoltaic equipment includes glass, tempered glass, cells and other materials. Introduces the solar cell module and the specific operation behind it.

1. Solar cell module (photovoltaic module), it is the most critical part of the solar energy resource utilization system and the core component of the photovoltaic power generation system.

Its principle is to form current through the battery and send it to the inverter to output electricity. On an ordinary solar panel, an inverter is a set of components that hold the cells in place, interacting with the grid to convert alternating current into alternating current. Common inverters such as AC level head inverter, AC buck boost, etc. Different devices have different application scenarios, and different environments will affect all aspects of solar cell modules.

2. What are the different types of solar panels?

At present, the type of solar panel that can be used most in the market is polycrystalline silicon solar panel, referred to as polycrystalline silicon solar cell, which is a polycrystalline silicon solar cell. The solar cell is made of monocrystalline silicon material. Polysilicon is the main material of solar cell elements. Monocrystalline silicon cells have high photoelectric conversion efficiency, and their photoelectric conversion efficiency can reach up to 26%. Monocrystalline silicon cells are generally made of organic silicon materials. According to its characteristics: simple structure, convenient for large-scale production; high material purity, mass production, low cost; high conversion efficiency, high packaging technology, high quality assurance and other advantages.

3. What is the difference between a distributed photovoltaic power station and a traditional household hydropower system?

Distributed photovoltaic power plants are installed and connected to the grid in a certain area, which can make full use of solar energy and other renewable energy sources, make full use of energy resources, and will not occupy too much land resources, which can save more costs for customers. It is also a good choice for ordinary families and will not take up too much land resources. The traditional household hydropower system is usually installed on the roof, fence or roof platform. However, due to the influence of solar radiation on buildings, trees and other equipment, and the photosynthesis of buildings and trees, it is necessary to re-install a solar radiation compensation device. In order to make photovoltaic power generation effectively play out.

4. How many modes are there currently for grid-connected photovoltaic power plants?

In the traditional power system, distributed photovoltaic power plants are the main way. At present, the existing distributed photovoltaic power stations mainly have the following modes: Ground power station: This type of power station is distributed on the urban suburbs or rural collective land, mainly photovoltaic power generation. Hydropower generation: The hydropower generation facilities are built near urban areas and rural areas. After the power mutual aid system is connected to the power grid, it is transmitted to the power grid through a dedicated line to finally realize the utilization of electric energy. Gas-electricity (natural gas, biogas fuel): This kind of power station is mainly located in rural areas or towns and uses natural gas as fuel to generate electricity. It is a relatively mature and feasible solution at present to transmit electricity to users through natural gas pipeline network.

5. Will the installation of photovoltaic cell modules on the roof affect the overall performance?

Answer: No. The production, installation and use of photovoltaic modules are carried out under strict quality control, and any components are qualified in the process of manufacture and installation. While each panel will be different, there are many similarities between them that have no impact on performance. Moreover, the service life of distributed photovoltaic systems is generally between 10-15 years, so if you want to increase power generation, regular maintenance is very necessary.
