According to statistics, solar engineering solar water heating systems can achieve building energy savings of 10% to 15%, while residential use of solar heating systems will save about 45% for building energy consumption.
In the carbon revolution from high carbon to low carbon, the energy saving and environmental protection of solar thermal utilization has attracted much attention. Solar thermal engineering is not only for the community to improve the product, has been part of China's development strategy, so it should be from solar engineering development strategy scientific evaluation of solar engineering different products, guide the healthy development of the solar industry, influence the national solar policy on the reasonable allocation of social resources, promote the healthy growth of solar energy enterprises, and strive for strong competitiveness.
China's solar energy industry layout is reasonable, the industry chain is perfect, the market size is huge. At home and abroad have intellectual property rights, pricing rights, the right to speak, which is China's industries in the foreign market rights of the most industries. China's solar energy industry in the world solar thermal market share of 95/100 scale.
Looking at the current situation of solar thermal utilization, foreign countries are mainly based on flat-plate solar energy, the domestic vacuum tube. In terms of energy use efficiency, flat-plate thermal efficiency can reach more than 76%. (Although foreign countries are dominated by flat-plate solar energy, but this is related to foreign solar energy social resources, as well as the geographical location. Flat-plate solar thermal efficiency can reach 76/100, is in the summer equatorial location, because flat-plate solar has a greenhouse effect.
Not all regions have the conditions. China's solar energy experience flat plate solar energy to vacuum tube development options. Vacuum tube solar water heater sales are decreasing, which is related to the economic situation of the financial crisis, the national economic policy, the law of vacuum tube solar water heater development and business behavior. It does not mean that vacuum tube solar products do not adapt to the market. Under the guidance of Jiayou Solar, we have invested a lot of manpower and material resources to develop all-glass vacuum tube leak-proof hair and vacuum tube solar products. (Improve the vacuum tube solar products, optimize the social resources of China's solar industry, to meet the needs of society's continuous progress.) In the integration of solar energy and building applications, flat-panel solar energy is more in line with the aesthetics of the building, and both roofing and heat collection dual function.
In China's solar water heater market, the current vacuum tube water heater occupies an absolute advantage is an indisputable fact, and the development momentum is also exceptionally hot, the prospect is even more fascinating.
However, we cannot ignore the fact that flat plate water heaters have emerged in recent years, becoming the highlight of the exhibition, the new favorite of domestic users, the mainstream of the international market, and even considered by some experts and scholars as the future direction of solar water heaters. If we are complacent in the scale and level of vacuum tube water heaters, and not to seriously study the advantages and development of flat-plate solar water heaters, we will not be able to look at the long term, grasp the future, and grasp the initiative to enter the international high-end market.
