Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Usually said solar power generation refers to solar photovoltaic power generation, referred to as \"photoelectric\". Photovoltaic power generation is a technology that converts light energy directly into electrical energy by using the photovoltaic effect of semiconductor interface. The key element of this technology is the solar cell. After the solar cells are packaged and protected in series, a large area of solar cell modules can be formed, and then combined with the power controller and other components to form a photovoltaic power generation device.
Solar energy is an inexhaustible source of clean energy. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Usually said solar power generation refers to solar photovoltaic power generation, referred to as \"photoelectric\". The photovoltaic power generation system consists of solar panels (components), controllers and inverters, which are mainly composed of electronic components and do not involve mechanical parts, so the power generation equipment is extremely refined, reliable, stable, long life, easy installation and maintenance. Compared with commonly used thermal power generation systems, solar power generation systems in addition to pollution-free emissions, but also has the advantages of short construction cycle and the use of building roofs.
As the cleanest energy in the world, solar energy has a wide range of uses. However, due to quality and price restrictions, the use of solar power in China is still at a low level, which is in great contrast to China's economic development.
On August 1, the National Development and Reform Commission announced a unified national benchmark for solar photovoltaic power generation, that is, solar photovoltaic power generation projects approved on July 1, 2011 and later (except Tibet) are executed at 1 yuan per kilowatt-hour. Many people in the industry believe that this is an important milestone in the development of China's photovoltaic power generation industry, photovoltaic power generation will also begin to embark on the road to commercialization.
With the large-scale development of China's photovoltaic power generation industry, the cost of photovoltaic power generation will be reduced, and it is expected to be equal to the traditional electricity price around 2014 and lower than the traditional electricity price thereafter. Experts predict that with China's support for the photovoltaic power generation industry, in 3 to 5 years, photovoltaic power generation is expected to enter every household.
Photovoltaic (Photovoltaic) : is the abbreviation of Solar power system, is a solar cell semiconductor material photovoltaic effect, the solar radiation can be directly converted into electricity, a new type of power generation system, independent operation and grid-connected operation of two ways.

At the same time, solar photovoltaic power generation system classification, one is centralized, such as large northwest ground photovoltaic power generation system; One is distributed (with > 6MW is the boundary), such as the rooftop photovoltaic power generation system of industrial and commercial enterprises, and the rooftop photovoltaic power generation system of residential buildings.
