The "brilliance" of photovoltaic power generation

   On July 5, the National Energy Group issued a notice on Actively Promoting the Development of Roof Distributed Photovoltaics in the Whole County (City, District), requiring all localities to take advantage of regional synergy, seize distributed photovoltaic resources, and promote the entire county (distribution, District) rooftop distributed photovoltaic development work.   

   With the development of technology and economy, as well as the acceleration of the process of industrialization, energy issues have become more and more of the world's concern and hope to be effectively resolved, so new energy sources are gradually being developed. Compared with other energy sources, solar energy is very popular with the general public with its unique advantages and characteristics. Compared with general nuclear power generation and coal-fired power generation, what are the advantages of solar power generation? Let's take a look together.

   Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then combined with power controllers and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less geographically restricted, because the sun shines on the earth; photovoltaic systems also have the advantages of safety, reliability, noiselessness, low pollution, on-site power generation and power supply without fuel consumption and short construction period. 76% of my country's land is abundant in sunlight, and the distribution of light energy resources is relatively even; compared with hydropower, wind power, nuclear power, coal-fired power generation, solar power generation has no emissions and noise, and the application technology is mature, safe and reliable; except for large-scale grid-connected power generation In addition to off-grid applications, solar energy can also be stored in a variety of ways such as water pumping, superconducting, storage batteries, and hydrogen production. Solar + energy storage can almost meet China's future stable energy demand.
