A Chinese senior energy official said that China’s solar panel industry is like a patient who live relying on the life-support systems, and only after intense integration and reduce production and excess capacity to get out of the “crisis.” This assessment show that because of the slowing global demand over the past year, solar panel prices have dropped by 30 percent. We can think that how serious the oversupply impact china solar panels industry (China is the largest producer of solar panels in the world).
Li Junfeng, deputy director of the Energy Research Institute, said that at least half of global solar panel production will suffer bankruptcy in the strong market competition and brutal elimination. Although the Chinese solar panel manufacturers impose to anti-dumping duties and countervailing duties in the United States, the EU is also investigating similar tariffs, but He said that the real reason is that Chinese solar production capacity driven by rapid expansion in credit.
Because of the oversupply of solar panel, global demand become slower, Suntech, Trina and Yingli and other large Chinese solar companies have cut back on production and struggling to maintain profit margins. The world’s largest solar panel manufacturer Suntech recently received a Nasdaq (Nasdaq) delisting warning but gained debt support from Wuxi local government where headquarters of Suntech located in at the end of September.
Li Junfeng, is one of the most influential renewable energy policy makers in China. He said that Chinese central governments will not give support to ailing Chinese solar companies in the next step, because companies need to responsible for their own problems. He believes that the initiatives of local government recently is help solar industry to killed themselves, because it will only exacerbate the problem of overcapacity.
He also said that if other local governments want to follow (provided aid) and Wuxi and Xinyu policy, it is no doubt that it would only hasten their death. Most Chinese solar companies are private enterprises. Local governments are often held a minority stake at local businesses.
EPS power supply, also known as EPS, EPS emergency power, fire emergency power supply. The full name of it is Emergency Power Supply. EPS takes the solving of the problem of emergency lighting, fire facilities and first class load of power supply equipment as the main objective to provide an emergency power supply system with an independent circuit which is in line with fire code. This system is able to provide emergency power under the state of emergency. It can solve lighting electricity problem or have only way to mains power supply and the second way is missing, or instead generator to constitutes a second power set, or as a third power in the needing occasions. However, UPS power means when normal AC power is interrupted, it transform DC power which output from the battery into AC power supplies.
Both EPS power and UPS power has electric bypass and inverter circuit, the difference functions between them is that EPS only has the function of supply continuous power, while UPS (on-line) is just has one total output way. EPS generally has less demanding on the inverter switching time and multiple outputs can monitor each output of circuits and capabilities of a single battery. It focuses on bypass in daily operation. Only when the mains supply is interrupted, it offers inverter power supply. UPS power generally emphasize on its three functions:
EPS has both power and UPS power mains bypass and inverter circuit, its function is the difference between: only functions of EPS is continuous to supply power, inverter switching time is generally less demanding, and multiple outputs available on each output detection and monitoring capabilities with a single battery, the daily focus on bypass, when mains power supply into the inverter, high power utilization. The UPS (on-line) is just the way the total output, generally emphasize its three functions: (A) regulated voltage and frequency stabilization. (B) Provide uninterrupted power supply for the one with which have high demand on the switching time. (C) Purifying mains. Energy efficiency is not high (generally 80% -90%). However, in Europe, countries with perfect power grid and power supply have been replaced the UPS inverter by EPS which has a short switching time (less than 10 milliseconds).
In china, EPS power supply is mainly used for firefighting or other electrical equipment industry which has less demanding for power supply and only emphasize power supply. UPS power is generally used for precision instruments (such as computers, servers and other IT industry load) which has a higher requires quality of power supply. In addition, it also has a great emphasis on the inverter switching time, output voltage, frequency stability, output wave of pure as well as free of all interference, etc.
