Solar power is an emerging renewable energy technologies, has realized industrialization is the main application of solar photovoltaic and solar thermal power generation.Solar photovoltaic power generation has the features of battery components are modular, easy to install and maintain, flexible use mode, etc., Is the most widely used solar power technology.Solar thermal power generation through the concentrated heating system heating medium, and the use of traditional steam generating equipment for power generation, began to increase industrialization demonstration project in recent years.

2011, Global PV additional installed capacity of 27.5 GW, more than 18.1 GW last year, Gundam 52% per cent, the global cumulative amount of installed more than 67GW.The 28GW around the world in installed capacity, Nearly 20GW system installed in Europe, but growth is relatively slow, which the Italian and German markets, 55% per cent of the global increase of installed capacity, 7.6 GW and 7.5 GW respectively.In 2011 Japan and India as a representative of the market demand of photovoltaic industry in the Asia-Pacific region rose 129%, its installed base are respectively 2.2 GW, 1.1 GW and 350MW.In addition, in the more mature markets of North America, an additional amount of approximately 2.1 GW installed, Gundam 84% per cent.
Of which China is the world's fastest-growing amount of installation of photovoltaic power generation in the country, the installation of photovoltaic power generation 2011 than 2010, an increase of 5 times per cent, the output of the battery 20GW 2011, accounting for 65% of the world.As of end of 2011, approximately 115 of total battery enterprises in China, with a total capacity of 36.5 GW.1GW in which the capacity of a total of 14 per cent of enterprises, 53% per cent of total capacity; In the enterprises and between the 1GW 100MW a total of 63, 43% per centof total capacity; The remaining 38 of production capacity are within this process, accounting for only 4% of the country's total capacity.Scale, technology, cost differentiation competition has gradually clear.Domestic shipments of the top ten components manufacturers account for 60% of the total output of batteries.

In the next more than ten years, the China PV market will be composed of independent power generation system to the grid-connected generation system, including the desert the roof of the power station and the city power system.China has great potential, the development of solar photovoltaic power generation With an active and stable policy support, and 2030 PV installed capacity will reach 100 million kilowatts, generating 130 billion kilowatts, the equivalent of building more than 30 fewer large-scale coal-fired power plants.The state subsidies of PV industry in the next three years, it will invest 20 billion, China solar photovoltaic power and ushered in a new one round of rapid growth, and attract more strategic investors to come into the industry.
