Analysis of the latest trends in solar power generation

For the general public, the concept of solar energy has been heard for many years, but it seems that it has not changed people's lives. The price of electricity is still not cheap, and the environment is still deteriorating day by day. After so many years of development, what is the current level of solar technology? How far is your life? 1. The high cost of photovoltaic power generation limits the commercial operation of photovoltaic power generation. Because of these advantages, such concentrating energy storage generators may soon realize large-scale grid-connected power generation, and then solar energy may really be around us. Compared with traditional thermal power generation, photovoltaic power generation has the advantages of low pollution and no resource consumption, but why is the development still slow? This is related to the current situation of photovoltaic power generation in my country and the characteristics of photovoltaic power generation itself: Photovoltaic power generation equipment At present, the most mainstream solar power generation mode in the world is the photovoltaic mode, which uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electricity. A technology , the key element is the solar cell. 2. The lag of photovoltaic technology has highlighted the problems of environmental protection and high energy consumption. Photovoltaic power generation realizes the desire of human beings to utilize solar energy. At present, my country, the United States, Japan and Europe are vigorously developing the photovoltaic power generation industry. The energy agency estimates that by 2030, photovoltaic power generation is expected to account for 10% of the total power generation. Photovoltaic products still have environmental protection problems, and domestic material circulation and clean production cannot be achieved, and large-scale application will pollute the environment. 3. 95% of silicon, the main raw material of my country's photovoltaic products, relies on imports, while products rely heavily on exports, lacking the ability to innovate independently, and become a processing factory abroad. 4. Photovoltaic power generation and energy storage is a technical bottleneck, which cannot achieve 24-hour power supply, and its application fields are greatly reduced. 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.
