The prospects of photovoltaic industry in the country

1. The photoelectric conversion industry chain formed by the application and development of silicon materials is called the "photovoltaic industry", which includes the production of high-purity polysilicon raw materials, solar cell production, solar cell module production, and the manufacture of related production equipment.

2. In addition to large-scale grid-connected power generation and off-grid applications, solar energy can also be stored through various methods such as pumping, superconductivity, batteries, and hydrogen production. It is the cleanest, safest and most reliable energy source in the future. Developed countries are making the development and utilization of solar energy as a long-term plan for the main content of the energy revolution.

3. The photovoltaic industry is increasingly becoming another explosively developing industry after the IT and microelectronics industries in the world. The best way to utilize solar energy is photovoltaic conversion, which is to use the photovoltaic effect to make sunlight hit silicon materials to generate electric current and directly generate electricity. Product prices have been rising steadily, business operations have generally improved, and the top four domestic polysilicon companies have all achieved full production.

There are several types of photovoltaic power generation

Three types

1. Independent photovoltaic power generation system:

Independent photovoltaic power generation system is also called off-grid photovoltaic power generation system. It is mainly composed of solar cell modules, controllers, and batteries. If it is to supply power to AC loads, an AC inverter is also required.

2. Grid-connected photovoltaic power generation system:

The grid-connected power generation system is a power generation system that feeds the renewable energy generated by photovoltaic arrays, wind turbines and fuel cells directly back into the power grid through a grid-connected inverter without battery storage.

Because the electric energy is directly input into the grid, there is no need to configure batteries, and the process of battery energy storage and release is saved. The electricity generated by renewable energy can be fully utilized, energy loss can be reduced, and system costs can be reduced.

The grid-connected power generation system can use the mains power and renewable energy in parallel as the power source for the local AC load, thus reducing the load power shortage rate of the entire system.

3. Distributed photovoltaic power generation system:

Distributed photovoltaic power generation is a way of generating electricity by converting light energy into electrical energy. This type of power generation is gradually entering the lives of ordinary people with its green and clean, easy to use, energy-saving and consumption-reducing characteristics. It is precisely because of its significant advantages and no waste of resources that it has been included in the key support industries by the state.

Is photovoltaic power generation harmful to the human body?

Photovoltaic power generation is not harmful to the human body. The principle of photovoltaic power generation is mainly that the relevant power equipment converts AC power into DC power and then connects it to the power grid. When the photovoltaic components are generating electricity, the electromagnetic environment is not only lower than that of normal household appliances, but they themselves do not generate any electromagnetic radiation.

Photovoltaic power generation is essentially a mode of solar power generation that does not generate radiation.

Due to its own characteristics, photovoltaic power generation does not produce noise pollution during the process of converting electricity.
