How does the manufacturer or integrator solar thermal heat change to the city?

At present, solar building integration is a hurdle for many solar thermal energy companies. Failure to do so means that companies will lose the initiative in future market competition. To do so, it faces the transition from manufacturer to system integrator.

Since the beginning of this year, many domestic solar water heater companies have been bitterly depressed: the effect of the rural policy has weakened, the market demand has fallen, the competition in the countryside has become fierce, and the transition to the cities has been weak. The old days that depended on the moist and survival of the rural market have come to an end.

For many domestic solar thermal energy companies, can they establish their own advantages in the integration of solar energy buildings and seek market discourse rights? For companies accustomed to the manufacture of water heaters, how can they quickly enter the construction field to find a breakthrough in solar energy integration? What changes will be made to the integration of solar energy buildings in the future at the national policy level? With these problems, a few days ago, a reporter from China Enterprise News interviewed Liang Junqiang, deputy director of the Center for the Promotion of Science and Technology of the Ministry of Housing and Urban-Rural Development.

The policy support has been increasing year by year in the National “Long-Term Development Plan for Renewable Energy” and clearly stated that it is necessary to focus on the development of the goal of solar thermal energy utilization, promote the popularization of solar energy integrated construction, solar energy centralized hot water supply projects in cities, and build solar heating and Refrigeration demonstration project. Promotion of household solar water heaters, solar houses and solar cookers in rural and small towns. It is estimated that by 2020, the total area of solar water heaters nationwide will reach 300 million square meters, plus other solar thermal applications, and the annual amount of alternative energy will reach 60 million tons of standard coal.

In this regard, Liang Junqiang told reporters, "Since 2004, China has promoted building energy efficiency to the national level. From the revision of the "Energy Conservation Energy Law", the enactment of the "Regulations on the Energy Conservation of Civil Buildings" and the "Renewable Energy Law," the country takes the lead. Starting from laws and regulations and other systems, we will promote building energy conservation from three perspectives: new construction, existing buildings, and building energy use systems.”

In recent years, the Ministry of Housing and Urban-Rural Development and the Ministry of Finance have launched a “Renewable Energy Building Application Demonstration Project” around the “Renewable Energy Law” to encourage and promote the unified design and planning of solar thermal systems for local governments in buildings. Liang Junqiang said that during the “12th Five-Year Plan” period, the state will increase the degree of policy promotion for the integration of solar energy buildings. From the original demonstration projects to the demonstration of urban and rural counties, the number of demonstration cities will be further expanded. ”

In 2009, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly promulgated two documents for the application of renewable energy buildings. One is to speed up the application in rural areas, and the other is the implementation plan for urban demonstration. In 2011, the two ministries re-issued the “Notice on Further Promoting the Application of Renewable Energy Buildings” and made it clear that by 2020, the proportion of renewable energy in the construction sector will account for more than 15% of the building energy consumption.

In this regard, Liang Junqiang particularly emphasized that solar energy companies in the promotion of solar energy building integration process, we must pay attention to the policy of attention and power, according to local conditions and actively participate in the planning of various local governments, through the development of concentrated contiguous projects to achieve demonstration effect. In recent years, local governments such as Hainan, Jiangsu, Zhejiang, and Shenzhen have mandatory requirements to install solar hot water systems in residential buildings below 12 floors, which all show government support.

Breakthroughs in traditional thinking This year, the central government proposed to build 10 million sets of affordable housing in the country in the next two years, and build 36 million sets of affordable housing projects for urban residents in the next five years. The release of this policy has once again stirred up the enthusiasm and motivation of domestic solar thermal companies to participate in the development of building integration. Companies such as Norit and Sun Rain also clearly stated that they must make full use of the opportunity of affordable housing and vigorously promote the application of building integration.

In this regard, Liang Junqiang said, “The construction of affordable housing in the country is definitely the need to use a large number of environmentally friendly materials and equipment, especially in the application of new energy such as solar energy, many opportunities, but the need to participate in conditional participation in accordance with the planning of various local governments Go in."

However, some current solar energy companies' problems in terms of thinking and ideas have caused Liang Junqiang's concern. “The understanding of solar energy companies for the industry needs further breakthroughs, especially in the integration with buildings, not just water heaters, but hot water systems. The branding of industrial products on many companies is too heavy, which will affect the development of solar thermal companies in the field of construction.In addition, various types of architectural design institutes are not well aware of and understand the application of new energy and building integration. , it will also limit the integration trend of the entire industry."

Liang Junqiang believes that "the root of the problem lies in how the company can change its thinking from industrial manufacturers to energy service providers. It can't just stay in the manufacturing process. It should be close to the building developers, to the design, product installation, and after-sales service. Waiting for a complete set of processes to form their own competitiveness and competitive system."

In the future development, solar energy companies must “take demand as the leading factor and provide them with real-needed system solutions and supporting services from the perspective of solving the hot water supply from construction units and real estate development companies”. In this way, the bottlenecks that constrain the application of solar thermal energy and building integration can be solved.

Liang Junqiang suggested that “solar energy companies may not be able to fully enter the design and installation field, but they can acquire some small design units through capital actions, set up construction and installation companies, get involved in the industry’s most upstream, own architectural design institutes, and take the initiative for some real estate development. The company provides professional construction design drawings, and can also provide its own professional construction and installation team to provide personalized services." 

Building the leading solar energy industry In the application of solar energy building integration, Liang Junqiang pointed out that from the perspective of the entire industry development, the solar thermal industry requires the emergence of several leading companies, forming the ability to own and develop the market and define market rules. Form the benchmarking effect of industrial development.

In recent years, China Merchants and Vanke have all proposed the development direction of “green real estate”, which means that there is still much room for the development of new energy companies in China. Liang Junqiang pointed out that for many solar companies, the core is to grasp the changes in market demand, have a strong supply capacity and ability to grasp demand.

"Especially in the future development of the enterprise, the thinking can be further broadened. At present, water heaters only provide low-grade energy, domestic hot water is dominant. In the future, you can consider heating and cooling the city, and even generate electricity as a power source. In addition to selling systems and providing services such as design and installation, it is also possible to consider energy investment for the entire building, invest in the entire construction project with the help of capital means and intervene in property management, carry out strategic division of work with real estate developers, and undertake part of real estate developers’ The function can be 'first charge, then free' mode, it can also be 'product free delivery service charge' value-added mode." Liang Junqiang frankly, for China's solar energy companies, the future in the integration of building space is huge, but Must be close to the actual needs of society.
