At present, solar photovoltaic industry has become the world's fastest growing new energy industries. International Energy Agency recently released a report, if the national policy to support the early installation of solar photovoltaic devices and long-term technological innovation, by 2050 solar photovoltaic power supply in the global ratio of up to 25%. The report is expected PV market in the next 20 years the annual growth rate of about 17%.

However, the level of existing HP PAVILION ZX5000 Battery, solar PV power generation costs are still high and the low utilization rate of such issues. To promote the development of solar photovoltaic industry, many countries introduced a subsidy policy, while large amounts of capital into the field. The difference with subsidies of capital to promote the pursuit of profit, national PV industry development trend vary widely.

Highly dependent on government subsidies

Spanish solar PV market can be said to fluctuations. In 2004, the Spanish government introduced a solar photovoltaic electricity price subsidies, provided subsidies to 0.44 euros per kilowatt-hour electricity. By 2007, the country's solar capacity from the original 100 kW up to 10 MW. The subsidies planned installed capacity of solar PV by 2010 to reach 400 MW, but actually had more than 2010 figure.

"The surge capacity of the high subsidies from the Spanish, even highly subsidized rates so that those design flaws of PV projects to profitability." The experts said, when the Spanish Government plans to introduce a new policy control excessive growth, its photovoltaic industry reached a total subsidy amount of 2.5 billion euros.

In 2008, the Spanish government introduced a new subsidy policy, photovoltaic electricity price subsidies reduced to € 0.32 per kWh, and to take measures to control the pre-registration, the total installed capacity. After the introduction of the new policy, the Spanish PV market then stagnated in 2009, the installed capacity decreased by about 95%.

Germany's solar photovoltaic industry in Spain, though not as big ups and downs, but is also leveraging the scale of government subsidies to achieve a rapid expansion.

Germany's solar PV industry, large-scale development began in 1000 the roof plan. To encourage the public consumption of solar energy, in 1991 the German government introduced a policy for households installing solar roof to provide subsidies. To the mid 90s of last century, the German network of solar equipment installed and households to 2000 and within a short time later expanded to 100,000.

Analysts pointed out that large-scale installation of solar equipment can help reduce costs and the popularity of Web-based solar equipment effectively promoted the further ACER ASPIRE ONE Battery of PV industry in Germany, "Germany's PV industry to survive in the cracks jumped from the owners large-scale production. "

Thereafter, to further reduce the cost of the development of photovoltaic industry, the German government to invite private companies into the field. To ensure that the benefits companies and individual investors, the German government has introduced a subsidy known as the buy back policy. The policy, companies or individuals in the installation of solar equipment will enjoy 20 years after the issue of solar power higher than the market price to sell the rights of the public power company. It is reported that bought subsidy policy has become one of Germany's energy policy an important part, was to write the country's "national renewable energy law."

In a series of policies, the German has now become the world's Photovoltaic power, installed capacity of PV systems in Germany in 2009 to 3.8 GW cumulative installed capacity of 9.8 gigawatts, accounting for 50% of the global total . Meanwhile, Germany's solar PV installation and manufacturing has been a world leader, the German company occupied 46% of the global market, and Germany has created over 10,000 jobs.

Pursuit of profit of capital to promote

Experts pointed out that the rapid expansion of government subsidies to industry, the industrial foundation is weak, if the policy change, the impact on the industry will be very serious. This is also the development of PV industry in Germany worries. Through the international financial crisis, Germany has clearly aware of its PV industry development issues, and timely adjusted.

This year in April, the German Parliament approved the Government's reduction of the solar photovoltaic industry subsidy scheme. Is expected in July this year, Germany's rooftop solar installation, solar PV electricity price subsidy amount will be reduced by 16% and 15%.

Policy of high subsidies to catch the last bus, the current German solar photovoltaic power station investors are desperate grab goods, China's solar PV module plant, polycrystalline silicon factory in full production over the recent sales.

"Now the market is in short supply in the state." Investor Relations Director Suntech Luo Yi believes that Germany will cut across the board PV electricity price subsidy is the fuse of the recent hot market, Germany's PV system installation business have hope that before the policy was implemented in time for breakfast to get goods.

China Sunergy market analysis manager, said Liu Dong, the first half of the total worldwide PV installed about 7 GW, and Germany at least 4 GW; expected to install PV systems around the world this year, the total amount of 13.6 Kyrgyzstan watts, an increase of 94.3%.

"The third quarter of the price of solar PV modules are expected to decline, demand will slow down." Liu Dong believes that the German government's subsidy is cut, the number of solar photovoltaic power project ROI a corresponding decline in the investment market in the new Chamber of Commerce of the judge.

Germany's high subsidies end, investors will go from here now we can not judge. The photovoltaic boom in Spain to be trained in the Spanish companies have fled, with their experience to new destinations, and win more investment opportunities. According to the Spanish Photovoltaic Industry Association data, Italy and the United States as the Spanish photovoltaic enterprises "going out" preferred state.

Is worthwhile to learn from Japan

Global warming and high energy prices, the Forced Japanese such a need to import 85% of the coal country of photovoltaic industry in an national development priority. Currently, there are tens of thousands of Japanese roof with solar panels. German solar PV industry is still dependent on government subsidies are different in Japan as early as 2005, the PV industry will no longer need government subsidies.

In order to develop solar photovoltaic industry, to develop the solar market in Japan, the Japanese Ministry of Economy since 1993 to implement the new Sunshine Project, 5 years PV technology research and development plans and promotion programs for residential photovoltaic systems.

"Through a series of government-funded and related research, development, demonstration and deployment, the Japanese solar cell manufacturers to upgrade technology and reduce costs has made great progress." Japan's trade ministry official said Japan's solar PV system installation volume ranked fourth in the world, of which over 70% of photovoltaic systems. 2009, Japan's newly installed solar PV systems, 90% of households with less than 30 kW rooftop power generation system.

Japan's nearly 500,000 residents to install a solar roof system, installation costs significantly reduced. Japanese residents in 1994 to install a solar roof system will cost 60,000 U.S. dollars, to the installation costs in 2005 fell to 20,000 U.S. dollars.

The official pointed out that in the course of the development of photovoltaic industry in Japan to the development of industrial productivity and coordinate the needs of consumers, and made remarkable achievements. Moreover, with the amount of solar photovoltaic system installation sharp increase in Japan's PV industry has the power to compete with other energy strength.
    Japan has concluded the current solar roof system of government subsidy, then Japan already has many of the world's leading solar energy company. Meanwhile, Japan's Economic and Trade Industries, is working to promote the next generation of photovoltaic technology research and development, the Japanese PV industry lay the foundation for sustained growth.

Experts pointed out that Japan's success is that the government in the development of solar energy photovoltaic industry in the process, pay attention to coordination of public investment, not only for research and industrial development with the subvention, but also actively displayed research results, promoting the Achievements. In addition, Japan has successfully implemented a solar photovoltaic power generation to compete with other IBM THINKPAD T42 Battery, the policy on the healthy development of PV industry is important.
