At this review meeting, experts from the Provincial Standards Office pointed out that since the 1990s, the continuous growth of the solar market has greatly promoted the technological innovation of the international solar industry. More and more countries are beginning to use solar and building integration technologies. The clean, environmentally friendly and inexhaustible solar energy is used in the fields of building water heating, indoor heating and solar cooling. The development, production, planning and installation of solar energy and building integrated systems are becoming more and more mature internationally.
At present, China's solar thermal utilization industry is still limited to the field of domestic water heaters. Solar energy is still lagging behind in the development and promotion of building integration. The main reason is that solar water heaters have special requirements for lighting, appearance and energy saving. The limitations in terms of installation orientation and installation location are difficult to integrate with buildings and urban landscapes. At the same time, there are defects such as typhoon and installation safety. These have increased the difficulty of promotion. For example, residents install themselves, causing different degrees of damage to the structure and function of the building, leaving hidden dangers in building waterproofing, bearing and other aspects; residents are not standardized installation, resulting in safety hazards such as wind and lightning protection; lack of planning, giving people a mess Feeling, affecting the urban landscape; there is controversy over the ownership of the roof, and the property management and maintenance are inconvenient in the later period. In addition, some solar installation pipes have a large amount of water and pipelines exposed, and the nighttime heat dissipation is large, resulting in waste of water; the product is not under pressure, and the pressure of the water supply pipe network is not matched in the high-rise building; the open-type hot water storage tank and the non-circulating water use mode It is easy to cause unsanitary water quality; the roof lighting area of ​​high-rise buildings is not enough to meet the requirements of all households. How to integrate solar energy facilities with buildings instead of becoming redundant parts of buildings is attracting more and more attention.
Wen Zheliang, general manager of Linuoruite Marketing Co., pointed out at the review meeting that there have been many bottlenecks in the development of the solar industry in the past 20 years. The self-installed messy solar energy has caused serious visual pollution. Many cities have introduced laws and regulations prohibiting the installation of solar energy. With the advancement of urban modernization, more and more high-rise buildings, only 10% of the residents of a high-rise building can meet solar energy. Just 10% of the customers gather the eyes of 3,000 pairs of manufacturers, and the fierce competition is evident. Why 90% of customer value can not be reflected, the key is technology, product upgrades and the introduction and implementation of the corresponding standards.
