Guangdong popularity of solar water heaters start from now

Solar water heaters are very economical, with a family of three, for example, initial installation fee or three thousand dollars, but installed at least a day after saving eighty-nine degree, provincial electricity can be 1,000 yuan a year, in 2023 to recover costs.

Unprecedented cold weather, coal oil and gas emergency, coupled with the recent meeting in Copenhagen, brings to mind the energy-saving and environmentally friendly solar energy. Guangdong Province, abundant solar energy resources, but alone to promote the use of solar water heaters, the current strong rate of about 2%, well below the national average of 10%, inexhaustible energy wasted. Reporters interviewed the experts and the public access to both the proposal to develop a low carbon economy, the province can start from the popularity of solar water heaters.

Utilization of solar water heaters in our province

Use of solar energy will significantly reduce carbon emissions and help our country to achieve emission reduction targets. According to statistics, the most mature solar energy utilization in the country\\ s city of Kunming, annual savings of 80,000 tons of standard coal, 11,100 tons of carbon dioxide emissions and 445 tons of sulfur dioxide. In addition, the use of solar water heaters are very economical for a family of three, for example, initial installation fee or three thousand dollars, but installed at least a day after saving eighty-nine degrees 1,000 yuan a year can be provincial electricity, 2023 to recover the costs.

Because of environmental protection, energy conservation, solar water heaters rapidly across the country, has reached an average of more than 10% utilization. Tibet, Yunnan and other areas with better solar conditions, the penetration rate has reached 30%, even in Jiangsu, Zhejiang, Guangdong and other solar conditions far better than the provinces, there are nearly 20 percent utilization. At present, China has become the world\\ s largest producer of solar water heaters and solar water heater market, to maintain world total holdings of 76%, and 20% to 30% annual pace. In the renewable energy industry, solar water heater industry has become China\\ s largest production scale, the greatest contribution, the highest level of independent intellectual property rights, and most widespread popularity of the green sunrise industry.

Hot summer and warm winter climate in our province, the province most of the time more than 3,000 hours of sunshine throughout the year, a year 4 / 5 or more conditions during the day with a collection of solar energy, solar energy utilization conditions are favorable. The province is to carry out solar energy research and development of the earliest provinces, but the slow progress in recent years, solar applications, solar water heaters mostly in hotels, schools, factories, and some research institutions, the general public rarely used. Solar water heater is always praised, penetration is very low.

In 2007, the Provincial Economic and Trade Commission, Science and Technology Department, Construction Department and the Department of Agriculture jointly issued a document, to speed up the popularization and application of s and promote the development of solar photovoltaic industry, and strive in 2010, the province\\ s urban and rural residents utilization of solar water heaters up to 15 % or more. Since then, the province has put forward new objectives using solar energy, urban and rural residents by 2010, usage of solar water heater to reach 30%. But more than a few years later, solar water heater is still hard for Cantonese Family: penetration rate of only 2% of the province has a strong, well below the national average, and falls far short of original goals.

Reason ? ?

Understanding and misunderstanding the policy is not implemented

Solar why it is difficult to enter public life? Guangdong Province Solar Energy Association, an official pointed out that people do not understand, management does not encourage, developers are not enthusiastic about is the main reason.

Guangdong people have the habit of bathing every day, a larger amount of hot water, supposedly saving and environmental protection should be more welcome to the solar water heater, but pervasive misunderstanding, such as fear cloudy impossible, for the first time such investment is too large. And some developers often affect the safety and appearance forbid residents to install solar roof. The province of small-scale solar water heater industry, technology is not mature enough, the product quality and after-sales service can not be guaranteed, the price is higher than traditional solar water heater products are not the main reason for people to agree.

Active or not management is also key. In Kunming, the relevant departments of the solar water heater installation is a clear-cut guidelines.

In our province, \"Guangdong Province public and residential building design and construction of s integration and acceptance of order\" are also being consulted, the \"Building Energy Conservation Regulations Guangzhou\" has not been scheduled at the end of the introduction. Reporters learned that the situation is that the current installed base of solar water heater is in a small number of residents did not report the case of \"stolen\" installed.

Province Solar Energy Society, supporting policies that are not related to the system, main features: First, the lack of a unified strategy to support policy, government decision-making still remain at the macro level, the mandatory application of solar energy development and utilization of the region\\ s lack of policies and regulations; second lack of system of economic incentives, lack of proper investors, users and related products, subsidies, price policy, low interest rate (discount) lending policies and system of tax incentives or mandatory tax policy.

Installed in the design of government subsidized

Residents of the solar water heater for the existence of misunderstanding, the provincial experts explain the Solar Energy Society, Guangdong sunshine for a long time, the radiation is large, and each year is only 60-80 days a cloudy day, even on cloudy days solar water heater can also be endothermic, but also with electricity and gas use with fully meet the demand.

Quality problems for the water heater, he suggested that consumers should buy qualified products, these products undergo strict quality control, and by the installation of a dedicated staff to ensure quality and safety issues do not appear; the Government should strengthen the solar water heater market regulations, standardize the market order, the to implement strict access system; install solar water heaters should go through rigorous training and licensing system for implementation; government subsidies as appropriate, will play for the promotion of solar water heaters to the positive role.

For installation problems, experts believe that existing technology can be solved. Floors of low water large return pump can be installed, so cold water back to the rooftop water tanks; as long as the qualified products, installation and technical personnel with appropriate expertise, we would not have water leakage problems.

The biggest obstacle at this stage is still the visual impact of the housing, through the promotion of solar water heating systems integrated with the main building to solve, can be implemented in the building roof, \"wearing a hat project\", a unified installation of solar hot water system, so that both from the insulation of buildings, leak-proof protection, and to achieve rational use of solar energy.

Promote the use of solar water heaters in the process, the Government\\ s policy is crucial. In 2009, the National Development and Reform Commission, Ministry of Housing and Urban-Rural Development and other ministries accordingly started the \"Golden Sun\", \"solar roofs\" and other projects, solar water heaters were included in the \"home appliances to the countryside\" policy. Shaanxi planning long-term development plan of solar, Kaiyuan, Liaoning Province, recently introduced policies to promote use of solar water heaters, 100,000 households, household subsidies, $ 150.

Europe, Japan and other developed countries to encourage residents to use solar water heaters, in view of the initial investment is too large, the government will subsidize 3 to 6 percent. These practices can learn from the province.

Fortunately, some parts of the province is also actively support the use of solar water heaters, sources in Heyuan City, Fengyuan City community, 500 households by the Government to support the installation of a household, an annual saving of more than 60 million high-Po Chen-pu before the village to spend the majority of farmers are also solar water heaters. In Zijin County, and many houses have also set up on the roof of solar water heaters.
