Photovoltaic Power Generation Enters The Fast Lane

At the 2021 National People's Congress, carbon peak and carbon neutrality were written into the government work report for the first time. We will achieve carbon peak in 2030 and carbon neutrality in 2060. The 14th Five-Year Plan is a critical period for achieving carbon peak and a starting period for promoting carbon neutrality. During the 14th Five-Year Plan, 60% of the carbon peak task will be completed, and carbon peak will be achieved in 2028 to lay a solid foundation for carbon neutrality.

To achieve the "3060" goal, the transformation of traditional thermal power generation has become an important part. Conventional energy is limited, and China's one-time energy reserves are far below the world average, about only 10% of the world's total reserves. Solar energy is an inexhaustible renewable energy source for mankind. It has the advantages of full cleanliness, safety, extensiveness, long life and maintenance-free, sufficient resources and potential economy. It plays an important role in the long-term energy strategy, and photovoltaic power generation came into being.

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It is mainly composed of three parts: solar panels (assemblies), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form a large-area solar cell assembly, and then combined with power controllers and other components to form a photovoltaic power generation device.

Compared with the commonly used thermal power generation system, photovoltaic power generation has no danger of exhaustion; it is safe and reliable, noise-free, and pollution-free; it is not restricted by the distribution of resources and can use the roof of the building; it can generate electricity and supply power locally without consuming fuel and setting up transmission lines; the energy quality is high.

The photovoltaic power generation system is composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems and other equipment. A large number of wire lugs are required in controllers, inverters, distribution cabinets, and tracking control systems. A variety of electrical lugs, such as plug-in, direct welding, spring, and fence types, can be provided, and a variety of track-type series terminal blocks such as JHY1, UK, WST, and MST can also be provided.
