Photovoltaic Status

- Jul 01, 2018 -

The traditional fuel energy is decreasing day by day, and the harm caused to the environment is becoming increasingly prominent. At the same time, there are still 2 billion people in the world who do not get the normal energy supply. At this time, the whole world has turned its attention to renewable energy and hopes that renewable energy can change human energy structure and maintain long-term sustainable development. Among them, solar energy has become the focus of attention because of its unique advantages. Abundant solar radiation energy is an important energy source. It is inexhaustible, inexhaustible, pollution-free, cheap, and human beings can freely use energy. The energy of solar energy reaching the ground per second is up to 800,000 kilowatts. If we convert 0.1% of the solar energy on the Earth’s surface into electricity, the conversion rate is 5%, and the annual power generation can reach 5.6×1012 kilowatt hours, which is equivalent to 40 times the world's energy consumption. .
In recent years, photovoltaic power generation has developed rapidly in the world. In the world, more than 10 MW-level photovoltaic power generation systems and 6 MW-level connected photovoltaic power stations have been built. The United States was the first country to formulate plans for the development of photovoltaic power generation. In 1997, the "millions of roofs" plan was proposed. Japan launched a new sunshine plan in 1992. By 2003, Japan's PV module production accounted for 50% of the world's total. Four of the world's top 10 manufacturers were in Japan. The new renewable energy law of Germany stipulates the on-grid price of photovoltaic power generation, which has greatly promoted the development of the photovoltaic market and industry, making Germany the fastest growing country in the world after Japan. Countries such as Switzerland, France, Italy, Spain, and Finland have also formulated plans for the development of photovoltaics and invested heavily in technological development and accelerating industrialization.
