March 10, 2023

The reporter recently learned that the urban construction and planning department of Hefei plans to select two roads in the Binhu New Area, introduce solar-powered street lamps, and promote the idea in the region. According to the current selection of two 3km long road test plans, the choice of solar lighting system will save about 260,000 yuan per year.

It is understood that the relevant departments initially envisaged the selection of two branches in the Binhu New Area and experimentally introduced solar lighting street lamps. If they achieve good results in terms of energy conservation, environmental protection, safety and reliability, they will be further promoted. Recently, the reporter got in touch with Anhui Yunlong Technology Development Co., Ltd., which designed the pre-plan design. Zhang Xiaoyun, the general manager of the company and a well-known expert in the solar lighting industry in our province, told reporters that the experimental road has not yet been finalized. The company is a 3 km long. The 16-meter-wide road has been designed with a plan to align the street lights with two lights at a distance of 40 meters. A total of about 150 feet of street lamps are required. Ordinary lamps offer 4,000 yuan / set, solar street lamps offer 12,000 yuan / set, although the latter cost is more expensive, but compared with the service life of 20 years, after analyzing the electricity bill budget, lamp replacement, maintenance and other factors, the total cost of solar street lights It is 2.025 million yuan, and the ordinary street lamp is 4.626 million yuan. The average annual savings of two roads is 260,000 yuan. The analysis data shows that solar lamps save investment, and the cost-effective features are quite obvious. They use green, environmental protection, renewable energy, and one investment, which will benefit in the long run. At the same time, since it does not consume coal power, it reduces greenhouse gas emissions such as CO2 and SO2, and plays an important positive role in environmental protection.

According to Zhang Xiaoyun, if solar energy lighting is promoted throughout Hefei, there will be about 1 million households in Hefei. According to the average annual consumption of 400 degrees of electricity consumption per household, the use of solar lighting will save at least 400 million kWh per year in Hefei. In addition, public lighting, fire-fighting facilities, and building intercoms are also powered by solar energy, saving at least 200 million kWh per year, so Hefei can save 600 million kWh a year.

In addition, the reporter was informed that in 2006, Anhui Province’s application for “using Hefei’s Grand Yuntian Garden Community as China’s first demonstration project to fully use solar energy” has been approved by the Ministry of Construction and incorporated into the national project library. . According to the design, the community lighting part is completely solar, including: residential lighting, courtyard and landscape lighting, underground garages, public corridors and fire exits, and corridor lighting in residential areas. The entire community can save nearly 680,000 kWh of electricity per year, plus community garden and landscape lighting, fire emergency lighting, public corridor lighting, and building intercom electricity, which can save 300,000 kWh per year. The community can save lighting every year. A total of 980,000 degrees of electricity.
