“Asian Solar City” of resources
Ningxia is the most abundant solar energy resources in China one of the regions, in the development and utilization of solar energy has unique advantages: terrain elevation, less rainy weather, sunshine time is long, the high radiation intensity, atmospheric transparency, and average annual sunshine hours number up to 3022.8 hours, annual global solar radiation per square meter of 5852 MJ to 8400 MJ, annual sunshine percentage from 50 to 60 percent, is a solar energy-rich region. Yinchuan is second only to Lhasa, Tibet and the “Asian Solar City”, where promising development and utilization of solar energy resources.
Have such advantages because of, autonomous regions and Yinchuan City, the development and utilization of solar energy as an important economic and social development, has issued a series of special preferential policies. In 1999, the regional government launched the “Sunshine Project”, and developed a solar energy development plan, annual research funding arrangements for several hundred thousand dollars, earmarked for solar energy technology development and product development. Yinchuan City, put the development and utilization of solar energy include clean energy action plan, a national clean energy first 18 pilot cities.
New energy into the people at home
As promote the use of solar energy, environmental protection departments in Yinchuan City approval of the strict control in the boiler, construction of small boilers in urban areas prohibited to gradually remove all coal-fired furnace bath tea, bath tea has a variety of furnaces were dismantled more than 300, as laid the foundation for the use of solar energy.
Yinchuan City, according to EPA statistics, the government’s promotion of encouragement, a growing number of solar water heaters into the homes of ordinary people. Population of less than 1 million people to install solar water heaters to Yinchuan City 27000 Taiwan. This alone, can save coal 1687 tons annually and reduce 27 tons of sulfur dioxide emissions, reduce smoke emissions 38.81 tons.
Reporter learned that, through the development and utilization of solar energy, not only to other energy saving, but also effectively protected the ecological environment. According to the Office of a regional animal husbandry responsible comrade, now uses a solar-powered water heaters can save coal 200 kg per year, annual savings of greenhouse mu 2 tons of coal, each solar cooker can save 1,500 kg of firewood per year. According to the present use of solar energy scale autonomous computing, the whole region at least a year to protect 12 acres of vegetation and save 150,000 tons of coal.
Present, there is solar water heaters range in price from 2,000 yuan to 10,000 yuan range, most residents can afford it. One use of solar energy up to 4 years of user told to buy a typical solar water heater price is around 2,500 yuan, bottles and saving 89 degrees every day, for 3 years or so will be able to recover the costs. Therefore, gas prices, power shortages and other pressed a series of energy, the solar energy will definitely be the concerns of consumers.
Blocked solar water heater installation
Yinchuan people in the process of cell arrival formalities SO encountered something bothering: residential property management company does not allow the roof to install solar water heaters on the ground that affect the overall appearance. Su said: “The solar water heater energy saving, environmental protection, the state encourages the development and utilization, why can not installed?”
For newly purchased homes, Yinchuan City, and Mr. Su, the people there the same question not unusual. Reporter learned that the last two years development and construction of Yinchuan City, a residential area,Real estateDevelopers and property management company refused to households to install solar water heaters is widespread, and some even still decorated with the owners signedDecorationManagement services agreement, specified non-residential roofs and platform owners to install solar water heaters.
Why the Government strongly advocated the “Sunshine Project” will this be blocked? To this end, reporters in Yinchuan City, Dongan property management center, a staff surnamed Zhang. She said, Dongan Area 2 is the sloping roof of residential tenants to install solar energy can not be arbitrary, all of the supply of hot water from the property management center.
The staff told reporters that the short service life of solar water heater, water pressure, water volume is small, easy to frozen pipes in winter, the installation inconvenience shortcomings. Need a hole to install solar energy fixed, it will be on the roof, walls and other damage in different parts, damage caused leaks waterproof layer, so that the interests of tenants damaged the top floor. And up and down the water pipes criss-cross, hinder the building facade and the internal focus of attention.
Need to improve the utilization
Urban high-rise buildings because less and less common area roof, the roof area with limited restrictions on the development of solar water heaters. At present, Yinchuan City, the growth rate of solar water heaters gradually slowed down.
Huang Ming Solar Yinchuan store staff surnamed Chen told reporters that solar energy is green energy, security, environmental protection, time investment, life-long benefits, there are other energy alternatives can not advantage. However, many real estate developers in recent years because of economic interests, built on the top floor loft sales, resulting from many quarters of the roof the roof into the top of the hill housing estates, resulting in households unable to install solar energy, store sales plummeted, from 25 units sold last month dropped to about 10 units now.
She said: “The perfect combination of solar energy and architecture, is based on the continuous improvement of practice, and can make building loading and load-bearing parts of reasonable use. In addition, the solar water heater on the building’s structure, view the results will not adversely affected. “
However, some people install solar performance of solar questioned. Public Yangwu Jun told reporters that while there are many advantages of solar energy, but because of its temperature down and weather linked to cold weather can not be used, so when the winter home of the solar fundamental is idle. Not only can not be used, as well as hidden??? Last winter nipped solar pipe to wash back home bath furniture.
This, the individual appeal: the Government should implement the development and use of solar energy, introduction of solar water heaters as soon as possible the integration of technology construction and installation regulations and standards, by the construction department of the design, construction, property management units to maintain unity management, so that the general public to make full use of solar energy of this emerging natural resources.
