First half of the solar water heater industry entered a stable period of development
[REVIEW] since the first half of this year, solar water heater industry continued to show a sustained and steady development, the overall economic development impact, it is from the rapid development of the steady direction.
Since the first half of this year, solar water heater industry continued to show a sustained and steady development, the overall economic development impact, it is from the rapid development of the steady direction.
Stable and sustainable growth of the industry as a whole
A recent survey of 36 companies in the first half of solar water heater market conditions, 36 companies divided by two categories: the first 12 key enterprises, compared to last year, two flat, but the project has increased, the remaining 10 growth rate of 20% -60%, 12 average increase of 32.6%.
The second category of medium-sized enterprises, a total of 24 survey, distributed in eight provinces. There are two negative growth (-20% – 30%), a flat, two less than 6% growth, and the remaining 19 up to 20% -70%. Sichuan, two of which increased 100%, and 24 overall average increase of 37.25% year on year.
At the same time, feedback on individual districts, closed down by more than 100, there is news that the region 1 / 3 of the sustainable development of enterprises, 1 / 3 of enterprises in general, 1 / 3 of enterprises out of business.
From a number of supporting businesses, such as apron, instrument parts, tank parts and other companies understand that in the first half growth rate of 20% or more, but there is a feedback vacuum tube business news inventory increases.
From the above survey results, the solar water heater industry has experienced 20 years of rapid growth, steady growth into line with the law of development. I believe that the solar water heater industry structure must be adjusted, the adjustment is to develop the content of one of the large enterprise, improve industrial concentration, the promotion of famous brands. Industry to form the backbone of enterprise-based, supporting business, engineering supporting industry chain enterprises reasonable. Number of low-level small business, can not always stay in the primitive stage, must be upgraded. No technological innovation, industrial upgrading, the market integrity of small businesses, competition in the market out, to be eliminated is the inevitable result. Lies in corporate restructuring and transformation.
Solar thermal industry in upgrading
Scientific and technological progress. Vacuum is to high, the auxiliary electrical energy, all-weather running hot water system, the development of intelligent control, the proportion of its products in 2010 reached 40%. Temperature in all-glass vacuum solar collector has passed appraisal and acceptance, Norit 150 ? vacuum tube efficiency as high as 45% or more; Emperor Ming in the temperature of 128 ? tube also through project acceptance, in an open tube temperature will for air conditioning, desalination, industrial use of technology and equipment to provide efficient collector. 400 ? -450 ? high temperature solar collector technology, and collectors will provide thermal power generation applications and development of key technologies and products, companies and Marino Emperor Ming of their respective companies developing new materials 400 ?, 4-meter-long vacuum tube samples has been developed successful, will form a production capacity; Pete\\ s 350 ?, 2-meter-long vacuum tube thermal power stations in 260KW application. China\\ s first thermal power station 50KW argument.
Applications expand. and domestic hot water bath to meet its basic functions, currently being expanded heating area of ??application, in addition to industrial and agricultural production is solar water heating system with hot water an important area of ??application.
Manufacturing equipment has improved significantly. All-glass vacuum tube solar collector system from the furnace into the rough, coating, cleaning, exhaust annealing, pull seal, to the packing factory installed card, automation, energy saving 30%, 40% efficiency, can be said that our vacuum tube solar collector technology and product level, an international leading level, the formation of China\\ s own industrial production patterns and self-development, self-made industrial, automated production equipment.
standardized power. National standards for solar water heater with 17 in 2010-2011 to develop a further 15, of 32, there are four industry-standard, can guarantee the production and use of water heaters. As far as I know, only as much as product standards, the international top.
In addition, the national compulsory standard \"domestic solar water heating system thermal efficiency of limited value and efficiency levels,\" the development and implementation of energy efficiency of solar water heaters and grading limit the development and implementation of national standards, will be following the solar water heater to the countryside, After the construction of new industrial base and accelerate industry consolidation, adjustment of industrial structure, improve product quality and level of another big move.
