[REVIEW] solar water heater short-lived problem, solar energy market is currently the most common and worrying phenomenon. Some small-scale , there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

      Recently, there have been two gentlemen came to a solar energy Co., Ltd., said to re-purchase of , and asked their purchase reason, get four points is difficult to believe but have to answer the letter. First, install a solar energy was more than a year, in particular, sunny weather, the sun one day, not how hot the water; the second, as long as the encounter cloudy or rainy days, even if only one day, put out the equivalent of room temperature water the water; third, stand on the verge of collapse before long, they do not want the victim way reinforcement is not assured continued use; fourth, tank manufacturers do not like can be used as promised 15 years, it took two or three years on leakage phenomenon.

Short-lived solar water heater problems, it is the current solar market, the most common and worrying phenomenon. Some small-scale solar water heater manufacturers, there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

The most fundamental flaw of these products on the life issues, and some can be used two or three years, some only a few months, there will be a variety of conditions, solar water heater caused a \"short-lived ghost\" is the direct cause There are four key points:

First, the bracket process rough. Solar water heaters stent selection and structural design and installation requirements are very high, professional design and installation of solar energy and protect the life of hard infrastructure.

Some small businesses do not stand a professional production equipment and paint techniques, combined with four recruitment of migrant workers formed the \"Install guerrillas\", both of these installers do not understand the design of piping, water heaters, the main fixed and other professional knowledge, but do not know a post of maintenance, resulting in problems abound. For example, the mounting bracket for fixed water heater parts, big brands use more steel bar, strong, corrosion-resistant, but some manufacturers are using wire fixed, resulting in some areas when confronted with heavy rain, hail and other inclement weather, there are many Solar water heaters will naturally shaky, even crashing to the ground.

Second, poor insulation. Solar water heaters produce hot water during the day and stored in a storage box, if the insulating layer of thermal insulation performance is not good, overnight, rainy days can not be used, or difficult to use. Solar water heater insulation resulting in poor performance is largely due to water heaters, insulation, insulation of hot water temperature determines the quality level and the amount of hot water. Good insulation layer using imported raw materials, such as polyurethane, low thermal conductivity, high temperature; high temperature insulation technology using automatic quantitative foaming, and high temperature aging treatment, lasting and stable high performance insulation.

Some poor materials, high thermal conductivity, foam is not uniform, night temperatures can drop more than ten degrees, rainy days experienced no hot water. Some black-hearted enterprise, in order to reduce costs, even using homemade benzene board, insulation effect plummeted a few months later, in 2012, after almost no insulation.

Third, poor liner selection. Most solar water heater manufacturers have said that the water tank is stainless steel. Also stainless steel, but chromium and nickel in stainless steel are very different.

Good solar water heater using high chromium high nickel stainless steel food grade liner, liner ensures durability, corrosion resistance and strong; inferior to use more low-grade stainless steel liner, the basic nickel-free, corrosion-resistant performance is poor, life is short .

Fourth, vacuum workmanship. Vacuum tube solar water heater core components, solar water heater is the \"heart.\" It directly determines the quality of the entire water heater performance. Performance by the use of vacuum coating technology and cleaning, coating, vacuum, seal and other processes and so on.

According to the Sun Co. researcher, some small business or a small workshop, there is not enough money to put into the tube advanced production equipment, but in order to survive, had to use the most original, most affordable tube. Such a low degree of vacuum tubes, high-quality products only 1 / 100, while the tube a lot of residual impurities and water vapor, in the face becomes hot gas, vacuum reduction. In low vacuum coating stability is poor, the intimal layer on two or three years of aging, loss, leading to a sharp attenuation of collector performance, can not absorb enough heat.

How to solve a series of fundamental impact on the life of the solar water heater problem?

First, governments at all levels to increase policy support for solar energy industry. Although China has long adopted a \"Renewable Energy Law\" and the Implementing Rules and other legal documents, but compared to Spain, Germany and other Western countries, mandatory energy-saving measures, the government promote the use of solar energy and not enough supervision, some high-end products efforts to promote the application is lacking.

Second, the solar industry to strengthen self-discipline. Advanced production equipment and high-end technologies that not all companies can have the strength to go into research and development. Throughout the region around the solar energy distribution, brand-name product has a huge market, they will be low cost, low-quality products to market rough, seriously affected the industry\\ s healthy development. According to incomplete statistics, the market has nearly 300 million units around the solar water heater products are not quality and maintenance support. Low-quality solar water heater to the bad impression left by the consumer impact of the industry\\ s image, it also hinders the healthy development of the solar industry pace.

Third, the use of positive publicity to strengthen the awareness of consumer acceptance. Most consumers choose only by the appearance of solar water heaters, solar water heater which one is better production techniques and products there is no clear understanding. The most unscrupulous manufacturers is to increase the publicity of the conceptual tube, and \"three-cavity tube\", \"three super-pipe\", \"Sanxin pipe\", \"purple pipe\", \"space control\" and other terms fly, a serious disrupt the concept of consumer choice, resulting in consumer products can not be a dispassionate look at the nature.

To this end we call on all kinds of manufacturers to fundamentally solve the problem of weak products with the highest quality products hit the market, all levels of government, the solar industry management organizations should take positive measures as soon as possible to integrate solar energy throughout the production of resources, so that \" short-lived ghost \"solar water heater as soon as possible,\" retired \", so as soon as possible onto the solar energy industry standardization, so that the whole of China and the world\\ s people are fully trust and use of solar energy facilities.
