the world energy supply security concerns and action on climate change, and promote the world within the scope of the rapid development of renewable energy technologies and industries, such as photovoltaic, wind power in growth rates above 20%. Renewable energy has become to realize the energy diversification, dealing with global climate change and achieve sustainable development an important alternative energy sources. Especially in the past two years, with the international oil price fluctuations and the effect of the Kyoto protocol, the implementation of renewable energy has become one of hotspots in the field of the international energy, got the wide attention of many countries in the world. By the end of 2006, the global renewable energy generation installed over 200 million kw, about 80 million kilowatts of small hydropower, wind power 7. 50000 kilowatts, geothermal power of 10 million kw, solar power more than 700 kw, solar photovoltaic power generation average annual growth rate over 60%, capacity of nearly 2 million kilowatts.

solar lighting energy-saving advantages of

along with economic development, our country's light will be improved to a great extent, the study of the green energy-saving lighting applications, will be more and more be taken seriously. Solar LED lighting' 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 As a cold light source products, lamps and lanterns has high cost performance, green environmental protection, safe and reliable, stable quality, long service life, easy installation and maintenance etc. , can be widely applied in the green lighting, road lighting, advertising light box, lighting, urban landscape lighting and home lighting systems, modelling but higher solar LED lighting lamps and lanterns is one-time investment is the bottleneck of its development.

at present, the lighting consumption accounted for about 20% of all electricity consumption, reduce illume is an important way to save energy. To achieve this goal, the industry has been the research developed a variety of energy-saving lighting appliances, and achieved some results. But, distance green lighting & throughout; Requirements also far, development and application of more efficient, reliable, safe, durable new light source is imperative.

by the end of 2006, China's renewable energy use a total of 200 million tons of standard coal, Does not include the traditional way of using biomass) , about 0. Renewable energy accounted for 5%, to 2010 a total energy consumption by 10% of the nation's taken a solid step toward the goal. At present, our country is from the following several aspects to promote the development of the domestic market of photovoltaic power generation: a, start sending to the village engineering; 2, on special project using photovoltaic (pv) power generation, such as the expo 【 The world expo, full world exposition ( World Exposition, referred to as 'World Expo) Is an organized by the host country government or government entrusted departments have great influence and a long history of international expo activities. 】 , games, etc; Third, building photovoltaic power station in the desert' Photovoltaic power station, is a use of solar energy panels, the use of special materials such as silicon, composed of electronic components such as inverter power generation system, connected to the grid and sending electricity to the grid photovoltaic power generation systems. 】 ; Four, mobilization of some cities started roof plan; Five, the research to enhance the competitiveness of photovoltaic power generation, electricity price policy ( Photovoltaic products 90% export, and the lack of domestic market, may limit the long-term development of China pv industry. Once foreign photovoltaic industry policy change or restrictive import measures to protect domestic industry, China in recent years a large number of horse pv projects will face a dilemma) 。
