As the most popular new energy in the 21st century, solar energy has always been receiving people's warm expectations. So, what is the development status of solar energy? 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 influence to people's lives. Great convenience. However, judging from the information gathered from various places, due to the limitations of related technologies and regions, solar energy in some areas is in a situation of "acclimatization". Let's take Huangjia Town, Shuangliu County, Sichuan Province as an example, let's take a look at the main problems faced by solar energy products!

At the end of 2007, the first solar street light demonstration street was established in Huangjia Town, Shuangliu County; in 2008, solar garden lights were installed in Baiguolin Village, Yongan Town. In the past three years, although more than 200 solar and wind energy street lights in Shuangliu County have played a huge role, they often encounter "cloudy days". In 2009, Mr. Li of Jiahe Village, Huanglongxi Town, who installed a batch of wind-solar hybrid street lights, remembered that the street lights were installed in summer. The annual lighting time is less than 1,000 hours, and it is less than 3 hours a day,” explained a person in charge of the county’s science and technology bureau. In the “Solar Lighting Technology Demonstration Project” in Shuangliu County, the problem of weak lighting conditions in Chengdu plagued them. Chengdu not only "Solar energy" is inherently insufficient, and "wind energy" is also very small. The manufacturers of solar wind energy street lamps have been struggling to design street lamps for the Chengdu area. They have launched new energy street lamps that can guarantee normal use after 5 consecutive cloudy days in Chengdu. However, , the cost of this new energy street light is very high. "Except for Shuangliu, solar street lights have not been widely promoted in various districts and counties in Chengdu. "Introduced by the person in charge of Dingming Photoelectric Technology Co., Ltd., which once provided equipment for the "Solar Lighting Technology Demonstration Project" in Shuangliu County. According to the relevant person in charge of Chengdu Urban Lighting Management Office, although solar street lights are very environmentally friendly, their off-grid characteristics determine Because of its poor stability compared with traditional electric lamps, once the light intensity is weak, the lighting effect will not be achieved.
