Large-scale PV concession bidding will start

Large-scale PV concession bidding will start




Most plants can all participate in the concession tender this case "lose out"

Because of the world's largest PV market - ahead of the German consumer market demand, China and Taiwan PV companies in the third quarter continued strong orders. It is noteworthy that China will start in the third quarter of 2010, eight provinces of the west concession bidding 280MW PV case and 50MW solar thermal power concession bidding case, the size of 10MW to enlarge several times higher than in 2009, is expected to build over two years completed, field operating time was 25 years.

We believe that, due to strong demand in overseas markets in 2010, component manufacturers repeat in 2009 the case of Dunhuang concession bargain should not happen, so winning this than the 2009 price would be picked up 1.09 yuan, in order to maintain a reasonable manufacturer return on investment is estimated at 1.1-1.3 yuan. We believe that most plants can all participate in the concession tender in this case some sort of relief. We expect the Chinese PV market in 2010 up to 300MW.

In addition, we expect continued increase in production capacity, making the price of polysilicon still test a low space. The current market price of polysilicon only stable at 50-55 dollars, is expected to offer the third quarter will continue to maintain the status quo, offer long-term polysilicon will continue dropping. A large number of shares in listed companies involved in most of polysilicon production is facing a shortage of cost-competitive, is not involved in short-term opportunity.

It is noteworthy that investors the world's largest PV market in Germany early in 2011 continues to lower its rates after the subsidy impact on demand worries, Jiashang the euro will also adversely affect Nokia earnings photovoltaic business, we maintain photovoltaic industry "neutral" rating.



Investment Recommendations

Investment direction in 2010, A shares the upstream polysilicon production costs are still competitive advantages in the polysilicon under the offer have an opportunity to continue dropping, it still isn'ta good opportunity. Component in photovoltaic cells, promising research can provide low-cost solutions to enterprises, the high-powered three-An optical concentrator technology and downstream integration of CSG's previous development strategy are more likely, with the results of other Haitong Group Support has also to note that we also optimistic about the key production processes necessary equipment, supplies (such as silicon wafer cutting fluid cutting required) and BOS components (such as photovoltaic power inverter), the relative stability of its huge profits, is the better investment direction We like Oak shares, shares of Wing Shun, Dragon Optical. Light and heat generating part, Higashiyama Precision shares with three flowers are light and heat has been involved in the system, with space themes speculation.

Siemens speeds up distribution of new energy

Siemens speeds up distribution of new energy




Siemens Energy Corporation (Siemens Energy) has the green energy companies from the Ital receipt of an order will be Apulia region of Italy (ApuliaregionofItaly) construction of 15MW of solar PV power plant. In addition to this project design and engineering services, Siemens will also provide energy power inverter, transformer, medium voltage equipment and control systems, and is responsible for the establishment of power stations.

Investment Advisor in the new energy industry chief researcher Jiang Qian pointed out that this is the third time in recent Siemens layout of the new energy field, by the end of May, Siemens Solar thermal energy has been put on the professional company Archimede Solar Energy SRL's ownership from 28% to 45%. In addition, Siemens has announced early in March with the Carbon Trust Company, High Tide with investment in tidal power generation company.

This is with the current global energy investment in the new line of new trends. Investment adviser in the latest release of "2010-2015 China Renewable Energy Market Analysis and Forecast of Investment Report" shows that the financial crisis, because the concept of progressive enjoys popular low-carbon, combined with national government support, the global number of large enterprises have joined or expanded investments in new energy field, which includes Westinghouse, Intel, Alstom, Nokia Siemens, General Electric and so on. Large enterprises have entered, how the new energy of such a sunrise industry has attracted the attention of all walks of life. For enterprises, means that an expansion of its development strategy; and the industry is concerned, it means the appearance of the development of a greater driving force.

Jiang Qian pointed out that, as a global engineering giant Siemens have long tentacles reach into new energy areas, but in the past the layout more concentrated in the areas of wind power. Siemens fan business in 2008 achieved sales of 19 billion euros, or about a quarter of total sales of Siemens. The recent solar and tidal power generation in the areas of distribution, indicating Siemens Wind Power for the new energy other than the sub-sector increased attention, and look forward to a slice of them.

To light and heat generation, for example, though from the domestic point of view, the past few years with several leading enterprises led the field of photovoltaic rising investment boom, relatively speaking, solar energy utilization in the other important forms of light and heat for power generation still in its infancy. However, from a global point of view, the momentum of light and heat generating no less than the PV. Currently running the international solar thermal power generation capacity of over 660MW, construction project more than 2000MW, the development prospects have been looking on.

The development tendency of solar industry

The development tendency of solar industry




1, experts believe that "building integrated solar energy is the future trend"

In recent years, energy efficiency and low wind blowing in the background, building energy conservation has become a focus of attention of the community in general. Related statistics show that China's building energy consumption to 30% of the total energy consumption, floor space heating energy consumption of unit 3 times for developed countries. Each year about 95% of new construction in high-energy construction. Therefore, the construction industry to improve the level of energy saving, low-carbon economy to improve the overall level of significance.

In addition, research also shows that in 2009 solar water heaters and hot water systems nationwide total reserves amounted to 145 million square meters. By ordinary market price of the coal, equivalent to savings of 22.5 billion yuan; by commercial electricity market prices to calculate the average, the equivalent of saving 56 billion yuan. While 145 million square meters of collector area, 44.51 million tons of carbon dioxide emissions a year. However, when mobile phones, home appliances, automobiles, increasing the penetration rate is high, in sharp contrast to the urban households in the domestic solar energy products, but really spend very little.

Even the lowest threshold of penetration of solar water heaters are far behind the city gas and electric water heater market growth rate, not to mention the significant energy-saving environmental protection, building-integrated solar energy. Of particular note is that while solar energy to rural areas to fire a handful of solar energy in rural areas, but the urban high-rise building of solar energy has been slow.

From the present situation of the localities in the integration of solar energy and construction is still a lack of unified planning and standards. To promote the development of building integrated solar energy and the state in 2007 was set up solar power Norit industry's only national housing industry base, three years to promote solar power Norit has been integrated with the construction of residential projects 34 million square meters, the equivalent of creating a completely new type of low carbon residential solar city.

Industry experts point out that the future course of construction planning, shall give special consideration to energy-saving elements, such as solar water heaters should be reserved for the interfaces. On the other hand, solar energy into the city construction, construction costs will increase, so one needs to reduce costs to enhance the scale of industrialization, the government introduced preferential policies and the need to be supported.



2, speed up the development of PV industry trend

In recent years the rapid development of the international PV, 2007, newly installed global solar capacity 2826mwp, which accounts for about 47% in Germany, Spain, about 23%, Japan 8%, the U.S. accounted for about 8%. In 2007, the solar photovoltaic industry chain, a large number of investment focus to the elevation of the new capacity. In addition, the solar PV business in 2007, the amount of loan financing increased by nearly 10 billion U.S. dollars, making the industry have been expanding. Although the financial crisis, Germany, Spain's efforts to support solar photovoltaic power generation has decreased, but other countries, policy support has increased year by year. Japanese government in November 2008 issued a "universal plan of action for solar power" to determine the amount of solar power development goals by 2030 is to achieve 40 times in 2005, and in 3-5 years, will drop the price of solar system to the current half. 2009, a special arrangements 30 billion yen in grants, special to encourage solar battery technology development. September 16, 2008, the U.S. Senate adopted a package of tax cuts, which will be photovoltaic industry's tax cuts (itc) 2-6 years of renewal. China's solar energy resources are very rich theoretical reserves of 1.7 trillion tons of standard coal per year. The potential of solar energy development and utilization of resources is very broad. China PV power industry started in the 20th century, 70s, 90s into the mid period of steady development. Solar cell and module production increased steadily year by year. After 30 years of effort, has ushered in a new stage of rapid development. In "Bright Project" pilot project and the "transmission to the village" projects of national projects and the powerful driving force in the world PV market, China's rapid development of photovoltaic power generation industry.
