The reporter from the previous day learned from the relevant departments of Baoding City that the city's “Solar City” project is progressing rapidly. Up to now, the eight centers of the city's urban area have extensively tasted the park, two main streets, 19 residential communities have used solar photovoltaic lighting, in addition to traffic lights, street-facing architectural highlight lighting and some small street lighting for solar energy renovation projects It is also pushing at full speed.
The dual-energy lamp became a beautiful landscape. According to the person in charge of the Baoding City Garden Bureau, after nearly two months of hard work by the construction workers, the people of the city’s people have tasted the train station square, as well as the Jingxiu Park and the Botanical Garden. The eight major centers such as Dongfeng Park and Binhe Park have all tasted the lighting and nightscape system of the park, and all of them have been replaced with solar power. Among them, the military school square installed 1045 盏 solar lighting, saving more than 830 kWh per day. In the People's Square, the newly installed 17-inch high-lighted Hua Deng, the night of the square is beautifully dressed. The newly developed "Wind Energy + Solar Energy" dual-powered lighting system is also installed here. The wind turbine and the solar battery pack on the top of the pole are powered together, which not only saves energy but also becomes a beautiful landscape.
As the first pilot of road greening renovation, the 3.6-kilometer high-speed lead green belt on both sides is equipped with solar floodlights 174盏 and lawn lamps 447盏, making the high-speed lead at night a beautiful “light band”. .
According to the person in charge, more than half of the urban green space will be solar-powered during the year. After the city's green space lighting is changed to solar energy in 2008, the green night lighting will no longer use coal power.
At the same time, the transformation of solar street lights on the main roads of the city is also advancing at full speed. At present, the two main streets of Dongfeng Road (Xiangyang Street to Chaoyang Street) and Wusi Road (Hengxiang Street to Yonghua Street) have all been replaced with solar induction lamps or LED lights. On the basis of the test sections of these two main roads, Baoding City will gradually carry out solar energy transformation for the main and secondary road lighting.
In addition, the city's traffic lights, building outline lights, night scenes, neon lights and other solar energy renovations are also fully rolled out.
Solar lighting heating can really save electricity According to the relevant person introduction, after field testing, using the two main road test sections of new technology street lamps, each street lamp can save 5-7 degrees of electricity every night. After the renovation of the city's solar street lights, the annual electricity cost will be more than 10 million yuan.
The reporter also learned from the Baoding City Construction Bureau that the renovation of the solar garden lighting system of the residents' community in the city is also progressing smoothly. At present, 16 residential communities such as New Century Garden Community, City Garden, Oriental Home, Taihe Garden and Fangqing Garden have realized solar energy transformation of courtyard lighting, and installed more than 700 solar garden lightings. Three districts, including the new generation C area, Shuofeng Park and Sunshine Jiayuan B District, have realized solar water heating systems, covering 500,000 square meters of residential buildings. According to reports, the city will install solar garden lighting nearly 10,000 baht in existing buildings and new residential areas this year, saving 3.6 million kWh, saving 2.52 million yuan in electricity costs, equivalent to about 1,260 tons of coal. The realization of 20,000 households of solar water heating systems in public buildings such as hospitals, hotels and bathrooms can save 22 million kWh and save 11 million yuan in electricity costs, equivalent to 7,700 tons of coal.
Solar energy will fully penetrate the people's lives. People in Baoding City said that in three to five years, solar energy will "light up" the night in Baoding City and penetrate into all aspects of citizens' lives.
Regarding the question of "the solar street light is not bright enough" proposed by the public, Director Zhang of the Street Light Department of Baoding Municipal Public Utilities Group said that most of the modified solar street lamps use efficient and advanced LED lighting. The most important feature of this kind of illuminating lamp is that it has low energy consumption and high luminous efficiency. The spectrum emitted by it is basically concentrated in the visible light segment, the generated heat is small, and the light emitted is soft and not glare. In contrast, the traditional street lamp uses high-pressure sodium lamp illumination, which has the disadvantage of large heat generation and certain glare radiation, and the emitted light makes people feel glare. This may be one of the reasons why some citizens reflect that the solar street lights are not bright enough.
Director Zhang said that after field measurements, the surface lighting effect of solar street lamps is in full compliance with national standards, and compared with traditional sodium lamps, it also reduces the light pollution caused by surrounding buildings. In the long run, solar street lamps are economical and energy-saving, and they are also a major trend in the development of energy-saving and environmentally friendly society.
