The lack of mass base of

The lack of mass base for the can not be widely accepted and recognized by consumers as a Mishap.

Solar water heaters in 2005, has experienced more than 30% per year after the rapid growth, and since 2009, the baptism of three appliances to the countryside, its market share rising, especially in the rural market has been well spread. At present, solar water heater market share far more than the traditional electric and gas water heater.

However, survey data is very worth considering. Late last year, the country\\ s 24 provinces, municipalities, Consumers Association conducted a joint solar water heater usage survey. The findings showed that 40.87% of the solar water heater can not be used to winter, it is 71.8% of consumers do not know how to identify the quality of the pros and cons of solar water heaters. The results make a lot of solar water heaters are very helpless. In this regard, a solar energy company CEOs jokingly said, consumers know that no gasoline car can not travel, but not to say that the car problem, but one solar water heater that, as long as the water temperature is not hot, put the blame solar water heater itself.

The lack of mass base for the solar water heater can not be widely accepted and recognized by consumers as a Mishap.

Indeed, in more than 30 years of development, China\\ s solar water heater in the more mature technology has been mastered, the whole industry over 600 billion market capacity. However, due to the lower threshold of the solar water heater industry, resulting in a large influx of corporate madness, so that there product homogeneity, of varying quality, a bad winter with reality.

If the above problem occurs only in a high-speed development period is the industry must go through the pain, then more than 70% of consumers do not know how to identify the quality of the pros and cons of solar water heaters, but the industry is worth more of reflection. Solar water heater industry today, solar energy companies in the high profits of the derelict, the blind pursuit of only the expansion of production capacity, expansion of the scale, sales promotion, but forget the most fundamental things, it is essential for the popularity of solar water heater products, to the end consumer a better understanding of this product.

Solar water heater, by definition, is used as an energy source for heating the solar water heater. Although 2009 will be included in the scope of financial subsidies, home appliances, but compared to traditional household appliances, \"relying\" solar water heater is definitely regarded as an alternative. Because the event of rainy weather, their effectiveness will be a greater impact, much less electric and gas water heater so comfortable and convenient and quick. This is also inherent in the vast majority of consumers view of the solar water heater.

In fact, as the industry continues to evolve and continuous advances in technology, solar water heaters are also quietly changing. Currently, in order to adapt and meet the rising standards of living brought about the concept of an increasingly discerning consumer demand, solar water heaters are the intelligent pursuit of product, quality health, and building integrated, and many other requirements. More importantly, in today\\ s society, the concept of low carbon environmental protection is becoming increasingly important in the case of solar water heater is being used by a single set of water heater to provide domestic hot water systems into the solution. Features from the previous to the use of solar-based, into a solar, gas, electricity, and even air a variety of energy sources complement each other, complement each other, designed to provide consumers with fast, comfortable, all-weather hot water service.

To completely change the lack of mass base of solar water heater, so that more consumers to understand and accept the solar science of publicity alone is not enough. Because in comparison to a standard to follow, the development of a more mature household appliances, solar water heater industry, long-awaited national mandatory energy efficiency standards has not yet been introduced. In the case of non-standard solar frequent controversy is not surprising. I believe that with the introduction and implementation of relevant standards and under strict supervision, in significant energy saving advantages of solar water heaters will have a better development.
 

Solar definitions and technical performance of

    What is solar energy?

    Within the sun together with the hydrogen nuclei into helium reactions, constantly releasing tremendous energy, space radiation energy to keep, which is solar energy. Large amount of solar energy, China\\ s land surface is necessary when the solar energy each year at 170 billion tons standard of energy. And this fusion reactions inside the sun can be maintained for a long time. An estimated several billion first billion years. Limited relative to the survival of mankind, the solar energy can be said to be inexhaustible.

    Solar energy and human environment

    A sustainable development of society should be that meets current needs without compromising future generations of society. Therefore, energy conservation, as much as possible with clean energy and environment must be one of the basic principles. At present, environmental pollution has become increasingly serious impact on our life and health and safety, including coal in energy consumption account for a large proportion is the main source of air pollution. According to testing, each square meter of s in their lifetime may be caused by burning coal to reduce emissions to the atmosphere of harmful compounds. Thus development and utilization of solar energy is an important option to reduce environmental pollution. 1992 United Nations convened the Global Development and Environment Conference, many countries have included the focus on developing solar energy projects.

    Energy is the material basis of human survival, since the 1970s, global energy crisis, not only endanger the future of society and seriously affected the production and living in today\\ s society. The development and utilization of solar energy, on the one hand can be widely used in hot water, electricity, refrigeration, heating and other aspects, on the other hand can save a lot of non-renewable resources such as oil and coal, will greatly ease the energy shortage and the serious the consequences. As early as 1973, the U.S. government on the development of a class of photovoltaic power generation project, then many countries have developed a corresponding development plans. Prospects for solar energy utilization in China China has a vast, rich in solar energy development and utilization of resources and a good foundation. Total in the National Solar Radiation 3.8 ~ 8.4 × 10 kJ / sq m, accounting for about 2 / 3 of the region greater than 2000 hours of annual sunshine hours. Wind, geothermal, ocean energy, are also very rich.

    After years of effort, solar thermal has made gratifying progress. With the gradual improvement of the product, the public awareness of civilization. Has a potential market of 900 million people of rural development, application of solar water heaters will be a large-scale progress in the near future will form an air-conditioning, refrigerator, color TV, like the mass market. Solar energy strategy for the country\\ s environmental protection cause, to one of the world market and become an international solar energy industry, \"city\", China must quickly use of solar thermal break and a world leader. This is our solar strategy.

    A brief history of solar water heaters

    Solar water heaters for its safety, energy saving, environmental protection, to facilitate the salient features of increasingly high-profile. As China\\ s all-glass vacuum tube and heat pipe technology continues to break the key, the world\\ s leading solar water heater made an unprecedented rapid development, increasing its market potential is huge. Following the gas, electric water heater, the solar water heater has become a new bright spot, gas, electricity, solar water heaters, three kinds of \"three pillars\" situation will soon be formed. The development of solar water heaters, has gone through four stages: nausea drying-type, flat, glass vacuum tube type, heat pipe vacuum tube.

    The first generation: nausea drying type. 20 years ago, long hours of sunshine in our other areas of the Northwest, has now been eliminated.

    The second generation: flat. Poor results due to frost, heat loss, easy to plot scale, low thermal efficiency and short life problems have been gradually phased out. Because of its low manufacturing cost, the project is still in a certain market.

    The third generation: all-glass vacuum tube. High collection efficiency, good insulation properties, can be anti-diameter of 25 mm hail attack, for temperature above -25 ? for use. Moderate cost. However, due to the vacuum tube through a long period of water heating, there is leaking, furring possible.

    The fourth-generation: heat pipe vacuum tube. China\\ s use of the United States used in aerospace, satellite-based advanced thermal technology, the super heat pipe and all glass vacuum tube combination, developed a new generation of heat pipe , fast heat conduction, thermal efficiency, especially for the sun inadequate or short daily duration of sunshine the area. Vacuum barrier of water, no scaling, antifreeze ability, good insulation properties, long life, is a market darling.

    Technical performance of solar water heater

    Solar water heaters for its economic, energy saving, environmental protection, safety, convenience, water volume, etc., has attracted worldwide attention. As the key technology of solar water heaters continue to make breakthroughs, solar water heaters have been widely used in households, factories, hotels, schools, military units, hospitals, etc. for the shower, hot water wash, and other required places.
