The domestic photovoltaic industry, which has experienced a series of blows such as the European debt crisis and “double oppositionâ€, is showing some positive factors: on the one hand, the state’s support for the photovoltaic industry has become increasingly clear; on the other hand, with the tide of industry consolidation The market situation, where supply and demand are seriously unbalanced, may change after the big waves. According to the latest research report from GTM Research, a Boston-based market research organization, after the industry consolidation, by 2015, Chinese companies will still occupy 7 seats in the list of the world's top nine leading solar module manufacturers.
The bankruptcy integration or the promotion of industry opportunities is first and foremost from the bankruptcy and integration of backward enterprises. Although the United States has already finalized the "double-reverse" of China's PV products, the EU is also closely following the case, but the days of local PV companies are still not good. Recently, news of bankruptcy or production cuts by many overseas PV companies has spread. Saikang Technology, a North American PV inverter manufacturer, announced this week that it has filed a bankruptcy protection request with the US Delaware Court of Justice under the US Bankruptcy Law. Previously, Q-cells, the world's largest producer of photovoltaic cells, filed a bankruptcy petition with the court. Berlin photovoltaic cell manufacturer Solon and German power station manufacturer SolarMillennium closed down in December last year. Another photovoltaic company in the US, SunPower, announced the day before yesterday that due to the sluggish PV market, the company will cut six of the 12 battery production lines in the Philippines, while reducing production capacity by 20%, and will also cut about 900 employees. According to the GTM report, PV modules in the solar industry are still overcapacity, and the average annual production capacity is expected to exceed 35 GW in the next three years. Low-cost silicon materials, price wars, withdrawal of government funds, and stabilizing market demand will continue industry consolidation. The agency's analysts predict that by 2015, overcapacity and low prices will lead to the existing 180 component manufacturers on the road to bankruptcy or acquisition. At present, the vast majority of high-cost manufacturers in the United States, Canada and Europe, it is difficult to compete with China's low-cost solar panels.
The Chinese company or Nirvana rebirth also expects that 54 of the 180 “bad fate†companies are from China. The Chinese government will continue to provide financial support to companies with large numbers of employees, repay short-term loans or encourage Chinese diversified industrial giants to acquire these companies. Potential beneficiaries of these strategies include Trina Solar, Yingli Green Energy, Wuxi Suntech, Jingao Solar, Jinko Energy, and Huihui Sunshine. The total capacity of these companies accounts for more than 20% of the global total capacity. However, Mehta said that so far, the degree of integration of the photovoltaic manufacturing sector has been less mitigating the ongoing overcapacity problem in the entire industry. The profitability of the PV supply chain is still challenged unless China's production capacity can be substantially rationalized. A person in the photovoltaic industry also believes that a key step for Chinese PV companies to get out of trouble is to achieve the survival of the fittest of domestic PV production capacity. "At present, local governments and local PV companies in many regions have become a community of interests, and they can't even talk about who kidnapped, but the consequences are that companies that have no survival from normal logic can't go bankrupt. In Europe and the United States, photovoltaic companies are seeking bankruptcy protection everywhere, and the internal mechanism of the market has become a core force supporting the development of the industry," the source said. “The road ahead will still be full of casualties. Between 2012 and 2014, we estimate that at least 60% of existing PV suppliers will be forced to withdraw from the market,†Mehta said. “In combination with multiple factors, we expect everything to Starting in 2013.†In his view, the demand for solar supply chains is likely to be balanced in 2014.
Roller for Aluminium Door
What material should I buy for the sliding door pulley,choose Aluminium Door rubber Roller ,Roller for sliding window and door, Double adjustable roller.
1. Pure metal wheel
Advantages: large bearing gravity, wear resistance and no deformation
Disadvantages: the sliding is not smooth enough, and it is easy to produce friction sound when pushing and pulling.
2. Rubber wheel
Advantages: non drying lubricating ester is attached to the surface of casters, so it can be pushed and pulled easily and smoothly without friction sound.
Disadvantages: the rubber wheel is composed of different materials, so the density of the rubber wheel is also different, resulting in the deviation of the center of gravity of the pulley, so the pulley is easy to derail during use.
3. Metal nylon double in one pulley
Advantages: the metal nylon double in one pulley has the advantages of large bearing capacity, pressure resistance, wear resistance and smooth sliding. It is developed based on the complementary principle of pure metal wheel and rubber wheel and the dynamic balance positioning principle of four wheels of oil vehicle, without eccentricity and wear. Therefore, many integral wardrobe now use this pulley to ensure the practicability of the wardrobe and facilitate people's life.
How to select sliding pulley
1. Look at the material of the pulley and the tightness of the wheel seat
Brief analysis: firstly, the pulley material must be strong and durable, and secondly, the pulley seat must also have certain weight resistance and sealing. Generally, 304 stainless steel and high-end synthetic materials are selected for the wheel seat, which has good sealing performance. Water vapor is not easy to enter the wheel to ensure the smoothness of the wheel.
2. See the fit between pulley and aluminum track
Brief analysis: the pulley and track must be closely matched, and the gap should be small, so that they will not fall off when impacted by external force, so as to avoid safety accidents.
3. Finally, it depends on whether the pulley and track match. It is best to adopt imported stainless steel and fully enclosed bearing structure. No matter how many times the sliding door is operated, it will not affect the service life, and the service life is up to decades.
4. The pulley and track are important, but the pulley should also be maintained during use:
a. When in use, avoid hitting the movable door with force, so as not to cause the movable door to fall off.
b. At ordinary times, the slide rail and pulley shall be cleaned regularly and lubricant shall be filled regularly.
c. The screws of the sliding block shall also be adjusted regularly to ensure the effective bearing and sliding of the sliding block on the movable door.
