The lighting time in Chengdu has less impact on the use of new energy street lamps. Relevant experts said that the improved street lamps can still be used normally after 7 cloudy days.
Solar street light? Then, you don’t have it on your head! Yesterday afternoon, Huang Auntie of the new rural concentrated residential area in Jiahe Village, Huanglongxi Town, Shuangliu County gave reporters a finger. Since Shuangliu County took the lead in using new energy street lamps in Chengdu, the village installed 50 wind-energy complementary street lamps in June last year. However, in the past six months, the villagers found that because of the low illumination time in Chengdu, ordinary solar street lamps are really not used. Convenience.
Very environmentally friendly village streetlights use new energy to generate electricity
The street lamps that Huang Auntie refers to are the lights on the roads and public places in the residential area. At first glance, there is no difference between them and ordinary street lamps. There is only a small windmill at the top of the pole. Below the windmill, there is another piece that protrudes outward. board. There is also a small green metal suitcase under the lamp. Below this is no cable! The villager Li Daye enthusiastically introduced that this is a new energy street lamp purchased in the village. It uses small windmills and panels to generate electricity, and electricity is stored in the metal box under the lamp.
When the night falls, the street lights are on. Our village's streetlights are energy-saving and low-carbon! The village branch secretary Li Zhiping said that this is a new streetlight jointly tested with the County Science and Technology Bureau and Dingming Optoelectronics Technology Co., Ltd., which can use solar and wind resources to generate electricity during the day and wind power at night. Machine power generation: that is the panel, which can provide 4-8 hours of power supply after 4 hours of effective light per day. In addition, these street light switches do not need to be manually operated, and the intelligent time controller automatically senses the brightness of the sky for control.
Very troublesome autumn and winter sunshine, less street lights are not long
But for Chengdu, which has less illumination time and less wind, can it guarantee power generation? It’s a problem! Li’s grandfather said that it’s just summer, every day, the sun shines high, and the new energy street lights work. However, it will go wrong immediately after entering the autumn and winter. The sun is small and the night is not bright. Uncle Li recalled that especially in the last few days of last September, it was raining for a few days, and some street lights only showed up for half an hour.
The same situation exists in other places. At the end of 2007, Huangjia Town of Shuangliu County built a demonstration street of solar street lights. In 2008, Baiguolin Village of Yong'an Town also installed solar street lights. Now there are more than 200 new energy street lamps in Shuangliu County. The villagers in use found that the new street lights were very delicate. Because the Chengdu area has less than 1,000 hours of light per year, and less than 3 hours per day, a person in charge of the County Science and Technology Bureau explained that in the Shuangliu County solar lighting technology demonstration project, the problem of weak lighting conditions in Chengdu also plagued them: summer Very good, winter
It’s terrible. It’s often cloudy for a few days, and the solar street lights are not bright, and even the light is not bright. According to him, the same street lamps were also used in Panzhihua and Aba Hongyuan, and the effect was very good, but the local lighting conditions were unmatched by Chengdu.
It is easy to improve and can still be used after continuous cloudy days.
Regarding the opinions of the villagers, Wang Xu, deputy general manager of Dingming Optoelectronics Technology Co., Ltd. did not deny that he believes that this is also the biggest problem facing the use of new energy equipment in Chengdu. The lighting conditions in Chengdu have brought a new proposition: the ability to use new energy street lights in areas with severe weather conditions. Wang Xu said that through the actual use of street lamps in Chengdu, technicians found that it is not impossible to let solar street lamps settle in Chengdu. At present, the company has produced second-generation street lamps to solve the problems reflected by the villagers. According to him, the improved street lights will be used in other districts and counties of Chengdu this year.
Solar street lights in Chengdu should be used normally after 5 cloudy days. Fan Chaoxun, senior technical consultant of the optoelectronic industry of Chengdu Municipal Government and chief expert of Chengdu Optoelectronic Display Engineering Technology Research Center, said that the use of this new energy street lamp must depend on its bad weather indicators. In the solar streetlights used in Aba, new controllers, new batteries and new technologies will be used to achieve the desired results. Fan Chaoxun said that the streetlights in Jiahe Village have been improved. Practice has proved that the improved street lamps can still be used normally after 7 cloudy days.
Hypothesis: Can solar street lights be promoted throughout the city?
After a series of technical improvements, solar street lights cannot be used as the main lighting of the city. Yesterday, the relevant person in charge of the Chengdu City Lighting Management Office denied this hypothesis. According to reports, although the solar street light is very environmentally friendly, its off-grid characteristics determine the stability of the traditional electric light is poor, the light intensity is weak, if the main road is used in extreme weather and the power is cut off, even if you want to restore the lighting through manual repair It can't be reached, and it is easy to cause an accident.
Accounting: 1 village saves 240,000 electricity bills in 10 years
Huanglongxi Jiahe Village purchased this kind of scenery complementary street lamp at a price of 7,500 yuan. The new 50-inch street lamp has a total of more than 370,000, which is twice as expensive as ordinary street lamps. Li Zhiping, a village party secretary, said that although it was expensive, the village no longer had to worry about electricity bills. The previous street light was a sodium lamp, and the sodium lamp lighting was 200 watts. Li Shuji calculated the account, calculated by 50 ç› ordinary sodium lamp, 80 kWh per day for 4 hours, 2000 yuan for one month, 24,000 for 1 year, 240,000 for 10 years. However, the new street lights are different. Although the county science and technology bureau subsidizes 30%, the village still has 250,000. The street lamps can be used for more than ten years. In the past ten years, there is no need to pay for electricity. Maintenance only needs to change batteries, which is quite cost-effective!
