Solar power lighting technology is more advanced than other power generation technologies, and it has low investment, safety and reliability, and a wide range of economic and social benefits. At the same time, the use of solar lighting can meet the needs of the social environment, and has a positive and important role in building a conservation-oriented society, an environment-friendly society, achieving sustainable development and promoting social progress. ??
Wuxi Suntech, whose main product is a crystalline silicon solar cell, has been sought after by investors in the US New York Stock Exchange, and its share price has climbed. However, when the solar cell manufacturing enterprises upstream of the solar energy industry have unlimited scenery, the social development and production companies that use solar lighting downstream are not highly concerned. What are their current living conditions, what restricts them from moving forward, and where is the future path?
Solar lighting energy saving effect is obvious
In 2006, Anhui Province applied to the Ministry of Construction to use the Grand Yuntian Garden Community as China's first demonstration project to fully use solar energy. According to the plan, the lighting part of the community is completely solar-powered, including: residential lighting, courtyard and landscape lighting, underground garages, public corridors and fire exits, and corridor lighting in residential areas, and residential buildings that use electricity. Zhang Xiaoyun, general manager of Anhui Yunlong Technology Development Co., Ltd., which designed the community solar lighting system, calculated the account for the reporter: The Grand Yuntian Garden project uses solar lighting, which averages 416. 1 degree per household per household. Community residents can save nearly 680,000 kWh of electricity per year, plus community gardens and landscape lighting, fire emergency lighting, public corridor lighting, and building intercom electricity, which can save 300,000 kWh per year. The community can save electricity every year. A total of 980,000 degrees.
If solar lighting is promoted throughout Hefei, Hefei has about 1 million households. According to the average annual consumption of 400 degrees of electricity consumption per household, the use of solar lighting can save at least 400 million kWh per year in Hefei. In addition, public lighting, fire-fighting facilities, and building intercoms are also powered by solar energy, saving at least 200 million kWh per year. Only Hefei can save 600 million kWh a year.
Industrialization urgently needs policy support
“The solar lighting system we have developed is now in shape, but it is difficult to industrialize due to lack of policy support.†Zhang Xiaoyun said that as a private technology company, they spent four years and invested more than 15 million yuan in 2004. The solar lighting system has been developed. The actual application has been in use for three years. The technology has matured, but it has not been pushed to the market. They expect the relevant departments to formulate product standards, acceptance standards, design standards and management standards as soon as possible so that they can develop the products that have been developed. The product is industrialized.
In recent years, the state has introduced a series of favorable policies to support the development of renewable energy, including the Renewable Energy Promotion Law and the Medium and Long-term Development Plan for Renewable Energy, which began in 2006. This series of benefits is an encouragement and support for the solar industry. "I hope that the government can further refine the policy and strengthen the implementation of the policy." Zhang Xiaoyun said.
The questions raised by Zhang Xiaoyun have attracted the attention of relevant departments, experts and scholars. During the National "Two Sessions" this year, the CPPCC National Committee members of the National Federation of Industry and Commerce made recommendations to the relevant government departments on China's current policy of relatively vague and lack of maneuverability for solar power generation. First, the government should improve the status and role of solar energy in renewable energy, so that it can enjoy the same policy encouragement as wind and biomass. Second, it should ensure that subsidies for solar-related industries are in place. Third, solar energy should be introduced. The taxation policy of the industry encourages the improvement of technology through taxation support. Fourth, policies should be formulated to encourage the development of China's solar cell market, arouse the huge potential of the domestic market, and at the same time formulate national standards for China's solar industry and products.
Wang Wanxing, director of the China Sustainable Energy Project's power and renewable energy project, who participated in the pre-legislation discussion of the Renewable Energy Promotion Law, said: "At present, the technology of solar power lighting is fully mature, but it is more difficult to promote it because of raw materials. Whether the price of single crystal silicon or polycrystalline silicon is relatively high, the cost per kWh is between 3-5 yuan, compared with the conventional power supply price of 0.3-3. 5 yuan, the price difference is obvious. It is very difficult to implement solar power lighting technology unless the government subsidizes electricity prices or introduces preferential policies to support enterprises in large-scale production.†He said that from the experience of foreign countries, the initial stage of solar energy development and utilization cannot be separated from government support. . Western developed countries have guided the way in which solar energy development and utilization generally adopt policies to encourage economic subsidies to promote the development of the solar energy industry.
