With the acceleration of China's urbanization process and the acceleration of urban infrastructure construction, the market demand for lighting products has gradually expanded. Under the background of energy shortage, traditional lighting equipment consumes a lot of energy, and there is huge energy waste, which also affects the urban ecological environment. This obviously does not meet the development direction of China's energy utilization, and also greatly limits the utilization of lighting equipment. effectiveness. The emergence of solar street lights effectively compensated for the above shortcomings. Solar street lights can reduce the amount of electricity used for lighting, which is an important way to save energy. Driven by green lighting projects, China's solar street lamp market has continued to grow in recent years. The solar street light industry is an emerging industry and therefore exhibits a relatively fast growth rate. In terms of its market size, the “2015-2020 Global Solar Street Light Industry Market and Investment Strategic Planning Analysis Report†released by the Industrial Research Institute shows that in 2009, the market size of the industry was 532 million yuan, and in 2013 it exceeded 5 billion. Yuan, 10 times that of 2009, shows that its development speed is fast. The application of solar street lights will produce more obvious social and economic benefits. First of all, from the perspective of social benefits, China's energy is more than 70% of coal, coal and oil account for more than 90, and these two kinds of energy plus natural gas are the main culprit in the production of carbon dioxide, so China's carbon dioxide emissions are early In 2006, it has surpassed the United States to become the world's number one. Therefore, China's energy structure is very unreasonable. From a geographical perspective, China has a very large source of solar energy. The total annual solar radiation in all parts of the country is 3340-8400 MJ/m2, with a median value of 5852 MJ/m2. From the distribution of total solar radiation in the country, the Qinghai-Tibet Plateau and Northwest China, North China, Northeast China, and Yunnan and Guangdong The annual total solar radiation in some low-latitude regions such as Hainan is above 5000 MJ/m2, which is a region rich or rich in solar energy resources in China. Therefore, solar energy sources in these areas can be fully utilized. Solar streetlights use clean, renewable energy, which reduces CO2 emissions compared to conventional high-pressure sodium lamps. If we turn all of our 20 million street lamps into solar street lights, we can reduce 25.8 million tons of carbon dioxide emissions, equivalent to $10.3 billion in carbon dioxide abatement costs. Therefore, investing in the solar street lamp industry can generate greater social benefits. From the point of view of economic benefits, according to the calculation, 4 meters of street lights and 8 meters of street lights, after the use of solar street lights, 4 meters of street lights and 8 meters of street lights save about 2190 kWh of electricity every year, electricity savings of 1,533 yuan. Therefore, in summary, the solar street lamp industry will continue to be valued by the country due to its obvious social and economic benefits. With the strong support and promotion of the country, the market scale of solar street lamps will grow rapidly. It is conservatively estimated that the market size of China's solar street lamp industry will reach 7.9 billion yuan in 2014 and will be around 60 billion yuan in 2020.
