Extensive use of solar water heaters in Guangdong was only 2% of solar energy –
Unprecedented cold weather, coal oil and gas emergency, together with the Copenhagen meeting held not long ago, so reminiscent of 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 access to the experts and the public have suggested that a low carbon economy, the province can also start from the popularity of solar water heaters.
Status??
Province utilization of solar water heater
Use of solar energy will significantly reduce carbon emissions, to help our country achieve emission reduction targets. According to statistics, solar energy utilization in the country's most developed city of Kunming, annual savings of 80,000 tons of standard coal, reduce emissions 11,100 tons of carbon dioxide and 445 tons of sulfur dioxide. In addition, the use of solar water heaters are very economical to family of three, for example, two or three thousand dollars upfront, but the bottles and saving at least 89 degrees every day, year, province electricity can be more than 1000 yuan, 2023 can recover the cost.
Because of environmental protection, energy saving, solar water heaters rapidly across the country, has reached an average of more than 10% utilization. Tibet, Yunnan and other areas with better conditions of solar penetration rate has reached 30%, even in the Jiangsu, Zhejiang, Guangdong, solar conditions far inferior to the provinces, there are nearly 20% of usage. At present, China has become the world's largest producer of solar water heaters and solar water heater market, to maintain the world's total holdings accounted for 76% and 20% to an annual pace of 30%. Renewable energy industry, solar water heater industry has become the largest production scale in China, the largest contribution, the highest level of independent intellectual property rights, popular and most widespread green sunrise industry.
Hot in summer and warm winter climate in our province, sunshine throughout the year in most parts of the province for more than 3,000 hours a year 4 / 5 or more during the day with the conditions of collecting solar energy, solar energy utilization conditions are favorable. Province to carry out solar energy research and development is one of the provinces at the earliest, but the slow progress in recent years, solar energy applications, solar water heaters mostly in hotels, schools, factories, and some research institutions, the general public rarely used. Solar water heaters have always praised in, penetration is very low.
2007, the Provincial Economic and Trade Commission, Science and Technology Department, Construction Department and the Agriculture Department issued a joint document, to speed up the popularization and application of solar water heating systems and the promotion of solar photovoltaic industry, and strive in 2010, the province's urban and rural residents to use solar water heaters rate of more than 15%. Since then, they proposed a new goal of using solar energy in our province, urban and rural residents by 2010, usage of solar water heaters to more than 30%. But more than a few years later, solar water heater is still hard for Cantonese families: the province has strong penetration rate of 2%, far below the national average, and far from the original target.
Reason??
Understanding misunderstanding
policy not implemented
Difficult to enter the public life of solar Why? Solar Energy Association of Guangdong Province, one official pointed out that people do not understand it, management does not encourage developers are not enthusiastic about the main reasons.
Cantonese has 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. Some developers often affect the safety and appearance forbid residents in the roof to install solar energy. Small-scale solar water heater industry in our province, 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.
Management's positive or not is also key. In Kunming, the relevant departments of the solar water heater installation of clear guidelines have been issued. In our province, "the public and residential buildings in Guangdong Province, solar hot water system integration and acceptance of design and construction" are also being consulted, the "Building Energy Conservation Regulations in Guangzhou" has not been introduced at the end as scheduled.
