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 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

    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.

Development of domestic solar energy industry ¨C setting water heater as an example

    With the increasing global tensions of traditional energy supply, new energy is not only sought after by many companies, but also by the state and governments at all levels attach great importance to the solar industry in particular, which has become widely accepted. According to Solar Energy Association released the latest data showed the country's output of solar water heaters to 30% annual growth rate in 2009, annual output of solar water heater break 40 million square meters, accounting for 50% of the world, retention capacity of 145 million square meters, accounting for 70% of the world's total, China has become the world's largest solar water heater producer and user countries. Norit only force a company's annual promotion of collector area installed on an area equal to the sum of the entire European Union, North America twice. However, nearly 6,000 domestic solar water heater companies, real own R & D capabilities and production scale of enterprises less than 20, the rest are mostly no-name brands and some local small businesses, and even many small family-owned business. These small enterprises were forced to survive and competitive pressures, backward production technology, quality management, confusion, product testing has been imperfect, and even cut corners, dumping and other serious impact on the reputation of the act, leading solar energy market order and chaos, there are many problems Some enterprises even faced a new crisis.

    1, the industry standard is too low, mixed enterprise Yulong

    The current industry standard solar water heater only a handful of GB/T19141-2003 "domestic solar hot water system technical conditions", GB/T18708-2002 "domestic solar water heating system thermal performance tests", etc., on the one hand the national standard is too low, such as the national standard only requires the pressure of the water heater capacity, did not make provisions for corrosion resistance, while the welds particularly susceptible to corrosion leaks; the other hand, lack of industry standards, such as the national standard on outdoor piping does not make the relevant provisions The pipes were frozen in winter the situation occur.

    Industry standard is too low makes the solar energy industry quite a mixed bag, enterprise quality uneven. Solar water heater industry in China has not implemented the production license system, also without going through 3C compulsory certification. In the case of imperfect standard, many companies do not blend into one production qualification. The threshold for the industry's low barriers to enter the number of enterprises in this area is not part workshop-style company is able to as "tailor-made shoes," as customized solar water heater, product quality and after-sales service are difficult to guarantee.

    2, a price war intensified crisis, the adverse long-term development

    High homogeneity in the field of solar water heater, there is no obvious advantage, not only the core technology of the enterprise choice of lowering production costs to deal with price wars. Some enterprises are often the raw materials used to produce low prices and then sold at low prices. This will not only further aggravated the cruelty of competition, but also so that there is some leakage of solar water heaters, non-Sheung Shui, a lot of pressure and poor quality.

In a "consumer use of solar water heaters in China Investigation Report" shows that consumer satisfaction with the solar water heater industry is low, 41.5% of users say very satisfied, most of which reflect the solar water heater products of poor quality, after-sales service with no or low technology content products and so on, even the consumers reflected just bought a water heater is only one day, which the water is leaked out.

"The market is too small, competition and too much." Of the original solar technology company in Hubei Fei Yang Chen Yang sales manager admitted, in the face of menacing tide of competition, in addition to cut-off than no other choice. According to relevant statistics, at present nearly 8 percent of the solar water heater companies have different degrees of sales decline, inventories and other issues, many of them fly like Hubei, solar energy technology company that Yang was forced to stop production of enterprises.

Industry analysis, solar water heater business in recent years the rapid increase in production capacity significantly increased, but the market has not expanded accordingly.

Meanwhile, the weather impact, solar water heaters consumer demand by a certain degree of inhibition. Many companies compete for a bowl, will grab badly beaten, many companies would go bankrupt, discontinued.

 3, the low level of brand, brand should be strengthened

"Many of the small enterprises have ceased production of the entire solar industry is a good thing." Chinese Academy of Sciences Guangzhou Institute of Energy Research Fellow Dr. Xu Gang that these low-technology, poor product quality solar products are out of the sound development of the whole industry is a positive significance. For the future direction of development of solar energy companies, industry experts generally agreed that while in the field of developing products, building brand is a priority. "Solar water heater companies in order to win in the fierce competition, only to start from the branding."

As industry leaders, since its inception in 2001, power Norit has been uphold the "responsibility to do create the world famous Sunshine," the purpose of all paid, low-key forward. They not only introduced the world's advanced solar technology in Germany, but also for the digestion, absorption, re-innovation, mastered the core technology of solar energy, even the Germans strict style of work applied to the production and service in every detail, widely by consumers The imperial gaze.

Norit adhering to scientific and technological innovation ability, while successively with Tsinghua University, Shandong Architecture University, and many other well-known to start college wide cooperation with enterprises, have taken up the banner of industry innovation. Which force Norit and Shandong Architectural University to complete the "shallow solar and geothermal energy use in the construction of key technology development and application of" project, implemented solar energy solar energy, shallow geothermal energy in the building the perfect combination, and get "2009 National Science and Technology Progress Award", also Weili Norit solar energy and building integrated expert added the name of a splendid touch.

At the same time, has been committed to leading the industry right direction to go in the strength of Norit lead the forefront of industry services. In addition to "creating the first service brand in China solar industry," the Declaration, but also launched the "one-dimensional, three-wide, nine-free" and "sunshine angel 139, Gold Service". At the same time, the country launched a 15,000 solar rescue center, there is no all-weather service for all maintenance and repair of solar water heaters.

Power Norit relevant responsible person said, solar energy industry is a sunrise industry, it's every step of the development is to have people to improve the environment, energy conservation is full of confidence and expectations. However, during the inevitable development of the industry problems, like shuffling through the Ebb Tide, the core competitiveness of enterprises did not definitely out, left behind is in the brand, technology, channels and other aspects of the enterprise-specific advantages.

Data show that in 2010 the EU hopes to install 3GW of photovoltaic power generation device, about 2030 to 200GW. The United States is expected to total installed PV power in 2020 reached 36GW. Japan plans to install approximately 2010 5GW.

Implemented in 1994 in Japan, "Asahi seven-year plan" has installed nearly 70,000 solar roofs by 2010 to install one million solar roofs. Germany in 2000 by the Renewable Energy Law to purchase a fixed discount price to encourage renewable energy, and in April 2004 and further supplemented and amended Renewable Energy Act, 2004, making Germany a substantial increase in PV power system equipment, and one stroke over Japan the world's largest installation of photovoltaic power generation system area. According to data provided Solarbuzz, 2004, Germany installed capacity of photovoltaic power generation system 361MW, up 152%, accounted for 39% of the global total; Japan to 278MW of installed capacity accounted for 30% of the world. Germany and Japan accounted for a global installed capacity of 2 / 3. At present China's battery products are mainly exported to the two countries. Million in 1997, the United States announced plans roof plans by 2010 to install 1 million rooftop photovoltaic and solar thermal systems.

Over the past decade, with the significant increase in world demand for PV market, coupled with large-scale manufacturing technology continues to improve and promote the rapid development of the world photovoltaic industry, photovoltaic cell production from 1995 to 78.6MW, up to 2005 of 1727MW, average annual growth rate reached 32.4%. Can be expected in the next 15 years the world will keep its annual PV production capacity of more than 20% growth, and even more optimistic estimate, by 2010, global solar production will grow by 4 times, 3 times sales growth, profit growth of 3 times.

World PV cell manufacturing mainly in Japan, Germany, the United States, Spain and other developed countries, including Japan's 2005 production of photovoltaic cells to 833MW, the world PV market share accounts for almost half of mainland China into the world's photovoltaic manufacturing 10 big country, with 2005 production of photovoltaic cells 128MW, listed fourth in the world, accounting for 7.4% of world market share.

This year in May, for the Tunisian Ministry of Industry of renewable energy, Secretary of State announced at a news conference: In 2009-2014 the president on energy and environment program areas, the conflict developed Prosoles plan, expected by 2014 to at least 5000 housing installation of solar PV installations, the Government and the suddenly the power companies will offer a number of incentives to encourage residential use of photovoltaic power generation industry. The program, the National Energy Fund (FNME) for installation of photovoltaic devices will provide the residents of the cost of installing 30% of the cost of investment, company STEG sudden power inverter is provided free of charge, residents can also get a 5-year 3000 dinar loans, and through STEG electricity bills to pay every period. In the field of renewable energy, suddenly in recent years to implement the third phase of energy conservation programs have achieved good results in 2007, rational use of energy saving of 700 tons of oil equivalent, accounting for 8% of energy consumption. 2008-2011 IV of the project goal is to make rational utilization of energy increased to 20% of renewable energy to 13% of the national annual energy consumption. Tunisia shows the importance of solar industry.

Chuxiong: Promoting the development of photovoltaic energy

Recently, Jing Kun Yu successful instrument to a new green energy Chuxiong 4 MW PV power plant EPC turnkey services, which will also apply here with independent intellectual property instrument green energy efficient 250 kW PV power inverter.

Chuxiong rich in tourism resources with the economic development in recent years, demand for energy is growing. But the conventional thermal power project seriously pollute the environment, therefore, the local government will turn their attention to solar energy.

"Cost and grid, which spans a career in solar power are two problems to solve the two problems One of the key elements of the key device in the power inverter on." Jing-yee, said Guo Wenjie, general manager of green energy.

According to reports, solar energy conversion rate is not high, average about 15%, and the solar cells must generate the DC into AC power inverter should be used for civilian and production, in this transition process will inevitably part of the energy loss. Therefore, the energy conversion efficiency inverter PV system determines the energy conversion efficiency and return on investment. If the energy conversion efficiency is low, it means the power system needs to be equipped with more battery life, greatly increased the costs, otherwise cost.

Occupy high-power photovoltaic inverter system cost ratio of 10% -15%, and a higher technological content, currently the world's leading SMA occupies 44% market share, many domestic enterprises do not own photovoltaic R & D and production capacity need to import from abroad, which further increases the already high cost of electricity.

Guo Wenjie said that in June this year, Beijing Miriam Green Energy JYNB-500KHE 500KW inverter power efficiency through the national "Golden Sun" certification, including environmental testing, EMC testing, performance testing. Posted by certified product allows the "Golden Sun" certification mark. It is reported that, in addition to external validation by the domestic market can be recognized by the World Bank project.
