As the most popular new energy source in the 21st century, solar energy has been receiving enthusiastic expectations. So, what is the current state of solar energy development? Of course, we cannot deny that as the cleanest renewable resource, solar energy is not only completely green and pollution-free, but also has a high utilization rate, which brings great convenience to people's life. However, from the collection of information, due to the relevant technology and regional limitations, solar energy in some areas there is a "acclimatization" situation. Taking Huangjia Town, Shuangliu County, Sichuan Province as an example, let's take a look at the main problems faced by solar products.

At the end of 2007, the first solar street lamp demonstration street was built in Huangjia Town, Shuangliu County. In 2008, Yongan town Ginko village installed solar garden lights. In the past three years, more than 200 solar and wind power street lamps in Shuangliu County have played a huge role, but they often encounter "cloudy days". In 2009, Grandpa Li of Jiahe Village, Huanglongxi Town, who installed a batch of wind-scenery complementary street lamps, remembered that the street lamps were installed in summer. "There are many sunny days in summer, but it is not good in autumn and winter, and the light is not long at night." Because the Chengdu area has less than 1,000 hours of light a year, that works out to less than three hours a day, "said a person in charge of the county's science and technology bureau, explaining that the lack of light in Chengdu had troubled them during Shuangliu's Solar Bright Technology Demonstration project. Chengdu is not only "solar energy" congenital shortage, "wind energy" is also very little, the manufacturers of solar and wind energy street lamps for Chengdu area in the design of a lot of difficulties, they have launched in Chengdu to ensure that five consecutive cloudy days can be normal use of new energy street lamps. But the new energy streetlights are expensive. "In addition to Shuangliu, solar street lamps have not been widely promoted in various districts and counties in Chengdu." Once for Shuangliu County "solar bright technology demonstration project" to provide equipment for the Dingming photoelectric technology Co., LTD. Person in charge of introduction. According to the relevant person in charge of Chengdu City lighting management office, although the solar street lamp is very environmentally friendly, but its characteristics off the grid determines its poor stability than the traditional lamp, once the light intensity is weak and so on, it can not achieve the lighting effect.
