The installation of solar water heaters has dragged the "sunrise industry" hind legs
The solar water heater is a typical "three-point product, seven-point installation". Consumers just buy the product home and cannot use it. Professionals need to install it according to the site conditions before they can be used normally. Consumers must not underestimate the installation of solar water heaters. In many solar water heater consumption disputes, many are caused by inadequate installation or failure. A citizen of Dalian City purchased a wall-mounted solar water heater. Although the merchant promised “safety†during the installation, there was still a problem after one year. The fixed solar panel has an expansion screw drilled from the wall, and the solar panel sways and swayed. At that time, the company that promised to "guarantee safety" did not even find out the reason for "falling solar panels". In the spring windy season, it is often seen that the wind blows down the news of solar energy, which is caused by installation problems. Since solar water heaters are installed on the roof, in urban high-rise residential buildings, solar panels are installed on the outer wall of the balcony. If the installation is not guaranteed, the solar energy becomes a “time bomb†suspended at high altitude. Lack of installation specifications At present, there is no corresponding technical standard and installation specification for the installation of solar water heaters in the country, and there is no relevant business organization to guide and manage. Although some cities have introduced some installation specifications, they only work for the installation of batches in the community. The installation of a single solar "storage" purchased by consumers does not work, resulting in a safety hazard in the installation and use of solar water heaters. In the solar water heaters that have problems in windy days, the phenomenon of “weak winds†is largely due to the lack of installation. For example, the number of cement used for water heaters should be fixed by screws on the bracket of the water heater and the base. In the installation of some solar-powered water heaters in rural areas, some installers simply “put†them on the roof, and they are finished with a thin wire. If it encounters bad weather, how much a thin wire can play is worrying. A citizen of Dalian had a problem with the installation of solar water heaters, causing the internal and external wires of the water heater to break, which caused the water heater to leak. The newly purchased sofas and furniture were soaked, and the neighbors also suffered, causing 60,000. Multiple direct losses. According to the survey, the cause of the accident was that the installer found a missing part when installing the water heater and purchased a similar product at random. In order to save costs, many companies have started an article on the bracket. According to the industry's recommended standards, the support plate should be at least 1.5 mm thick and 100 mm wide. Some solar water heater manufacturers have cut corners. The support material is only 1-1.2 mm thick and 60-70 mm wide, narrow and thin. There are some bracket plates with multiple borings. Such brackets obviously have a great resistance to torsion and wind resistance. Professionals say that the installation of solar water heaters is still inside the industry. First, the installation units are not standardized. In addition, some wall-mounted solar water heaters installed outside the residential balcony, if the quality is not good or the installation is not standardized, there will be danger of falling off. It poses a threat to the safety of pedestrians passing by. Looking at the news, there is indeed a case in which solar energy falls into the pedestrians and causes death. The safety of solar installation cannot be ignored. Installation problems and manufacturers and businesses "kick the ball" The characteristics of the solar water heater industry are that retail terminals have the most profit. Since the sales of solar water heater products are mainly driven by terminals, “investment is king†is the characteristics of the whole industry. Therefore, although the profit of this product is as high as 50%, only 5% of the manufacturers, 15% of the prefecture-level dealers, and 30% of the township retailers. Under normal circumstances, the installation of solar water heaters is also carried out by retailers, but when there is a problem with the product, such as disputes caused by improper installation, retailers and manufacturers often kick each other. Our wire and cable requires for product quality certification documents from the supplier, The wiring shall have the factory quality certificate documents, including: certificate of quality (the certificate has the production license number and the "CCC" certification mark), test report and the "CCC" certification certificate; he quality certificate of electric wire shall be the original, if it is a copy, the copy shall be consistent with the original content, with the official seal of the original storage unit affixed, indicating the place where the original is stored, and the signature and time of the handler; The manufacturer shall have the business license of enterprise legal person.
