Sustain high growth solar industry

Sustain high growth solar industry

It is understood that the top executives of solar laptop battery energy companies are worried that the global shortage of polysilicon raw materials, solar energy industry may not be able to continue to stabilize over the past few years growth.

Polysilicon is the main raw material for solar cells acer battery. The world's largest solar cell manufacturer Sharp Corporation of Japan, head of solar systems on Wednesday, warned that Takashi Tomita: soaring prices of silicon materials show that the suppliers can not meet demand. He shortage of polysilicon raw materials are very concerned about: the shortage will lead to price increases, and prices will eventually result in solar market stagnation. Solar markets around the world now account for 1% of the energy market, with an estimated value of about seven billion U.S. dollars annually. According to the European Renewable Energy Council study, solar energy industry in 2030 will account for the global energy market, 8%. Big country in solar energy in Japan and Germany, the government paid a large number of grants for research does not produce carbon dioxide, clean energy - solar energy, solar energy industry in this rapid development of the two countries. Solar-grade silicon from the unit price in 2000 of nine U.S. dollars a kilogram up to 60 U.S. dollars this month, while the solar energy industry since 1997 has maintained a 30% - 40% of the annual growth rate. Growth appears to have high-speed braking. Silicon is the Earth's surface constitute the largest element, but the purification to meet the demand for high-tech form of technology such as the high cost of polysilicon.

Before and after 2000, because of the high-tech bubble burst, a never-ending consumption of semiconductor manufacturers of polysilicon to the solar cell company stock with the prices of raw materials. But now, high-tech electronics industry tend to the healthy development of solar energy industry to be more abundant and capital-chip manufacturers compete for supply, because the silicon chip is far less than the silicon solar cell, the chip will be able to more easily bear the this expenditure. On the other hand, polysilicon manufacturers are developing low-cost solar-grade silicon products, it does not need to reach the purity of semiconductor silicon. However, these alternatives also need a few years of production time.

Silicon solar cells occupy 80% of the cost, so the short term, the manufacturing costs of solar energy industry also can not substantially reduced.

PHS booth solar charger (Figure)



Yesterday, the public telephone from Beijing Netcom Management that Netcom did not in the city where the laying of communication cables installed as07b72 battery, acer aspire5520 battery, acer aspire5520g battery in a telephone booth PHS 200, PHS signal used to provide public service. These characteristics of a telephone booth is recharged using solar panels, solar panels on top of a telephone booth.

According to Netcom, the Ministry of Public Management, then introduced Mr. Yuan Zheng, most of these booth to start using battery-powered, the use of less than two days during the height of a battery to be replaced. To this end, the CNC manufacturers contact with a telephone booth, telephone booth in these step by step to install solar panels for battery charging . At present, solar telephone booth to replace the battery once a week to save costs.

Orange also when the energy

Florida citrus is one of the world-famous town is also the largest U.S. producer of citrus, orange peel waste only have nearly 800 tons per year, most used for cattle feed. However, the company Ener1 Tangeretin puzzling as to the energy, extracted by distillation of methanol processing.

The company is investing 1.1 million U.S. dollars for the development of this project, from orange peel extract hydrogen-rich gas into a fuel cell in the energy, stored in cylinders in for the modernization of the station to suspend the use of the interstate. Non-profit program of the Florida Hydrogen Ener1 has given the company's 550,000 U.S. dollars financial support to help them in the next year to complete the project. The aim is to give millions of drivers to be an example to show that orange peel extract from the waste the potential of hydrogen energy.

Florida already has several such hydrogen energy project. In February this year, Bush and Ford Motor Company agreed to the state became the first to use hydrogen energy in the state of the bus station. So far, Ener1 has produced one kilowatts and 150 kilowatts of fuel cell samples, they hope to be able to produce 18 months out of the station to suspend the use of 10 kilowatts to the fuel cell.

UNION (Union) batteries colloid volume exported overseas

China and South Korea by the concerted efforts of both scientific and technological personnel, the introduction of the German Colloid digestive cell technology based on research and development through the past three years, the successful launch in 2004, licensing colloidal UNION sealed lead-acid acer aspire5920 battery, acer aspire5920g battery. UNION licensing 12V gel battery, including series, 6V and 2V Series Series a total of three categories. 6V series 6V180AH and colloidal 8V180AH batteries used golf carts for domestic first with the safety, environmental protection, maintenance-free (no added water), long cycle life characteristics of a traditional rich fluid replacement battery products by the European U.S. users, the export volume has begun to UK / Spain and other countries. 12V series JMX121000 (12V100AH) gel batteries, the use of long-lived, deep-cycle resistant design, high and low temperature-resistant properties, and is ideal for solar photovoltaic power systems and outdoor battery backup power, the battery models in Australia has been a well-known solar photovoltaic power system approved by the manufacturer, started in 2005 Australia exported.

Battery as a result of the use of colloidal colloidal unique technology, more traditional style of the rich liquid medium depleted battery and modern AGM-type battery, it has a longer life cycle of good performance, high and low temperature-resistant properties, and highlight the advantages of higher reliability, will be widely used in a variety of highly reliable power back-up areas, such as solar photovoltaic power systems, power systems, communication systems, it is important to data center, aviation and the safety of the MTR system, unmanned station and outdoor such as standby power.
