Residents take advantage of solar heating

hin the floor to increase the temperature, there are many Qiang method, he would most like to emphasize energy efficiency and low. Zhang Qiang said, the residents of the home indoor coWinter is a troublesome problem for some township residents still in the wood the firewood burned Wang can only guarantee the kang is hot, the house still cold. This problem did not stumped the Changchun City two districts persuade farmers Town residents Qiang, the same wood fire, Zhang Qiang, the use of solar energy, wall insulation, the house reasonable distribution of the heat source, such measures can make the the bedroom temperature reaches above 20 ℃. Now, he would like to promote these measures, to improve the living environment of more township residents.

    Make full use of solar energy

    Zhang Qiang's house located near persuade farmers Town granary, an area of ​​120 square meters, cottage living room, bathroom is reasonably carved out. Zhang Qiang home around 15:00 yesterday, the reporter walked one hot flapping body came. Zhang Qiang took out the thermometer to measure the bedroom temperature, the reporter saw 20 ℃, which is quite difficult for a roasted corn stalk and firewood housing.

    Zhang Qiang said, he has mainly taken the use of solar cell energy and external wall insulation measures. First, he intentionally build houses the Chaoyang face the bedroom window bigger, so the sun every day full exposure to the house. The master bedroom windows of up to 3 meters in width, 1.8 meters high, the width Ciwo reach 2 meters. He will also shorten the bedroom of the north-south distance east-west distance growth, so the house to maximize absorption and retain the sun's heat. Bedroom north side no windows.

    Zhang Qiang laid around the house about 5 cm of extruded plate, to ensure that the heat is not lost, the chill could not come. Zhang Qiang said, the the extruded plate he is even better than the benzene plate material. In addition to the external wall insulation, windows, the buckle plastic sheeting is also essential.

    The heat source allocation want reasonable

    With these measures, Zhang Qiang, a daily morning and evening twice burning firewood can guarantee the the bedroom temperature reaches about 20 ℃, living room, bathroom, cottage, warehouse temperature is relatively low. Zhang Qiang said, this is because of the the house heat sources to be allocated on a reasonable basis, such as the living room arrangements by kang passed to the bedroom, some heat will pass solar panel through the wall to the living room in the middle of the two bedrooms, light a fire, heat. The bathroom arrangements beside the stove for cooking, heat will pass through the wall to the bathroom. Zhang Qiang He also installed a water supply pipeline, simply open the valve well water will automatically flow into the home, and security solar water heaters, anytime, anywhere hot shower.

    Kang installed Sizzling conserve heat, electric geothermal installation wital burning in the villages and towns of 20 ℃ lot, but had a few thousand dollars a year. Comfort measures can guarantee less like his low-carbon save money, so he wanted to promote, hoping to improve the living environment of more township residents.

Apollo solar material component sales growth next year

Hui Ka Wah, executive director and chief executive officer of Apollo (00566.HK) solar module sales next year are expected to grow by 20-30%, but the price is hard to be increased substantially, the company will continue to improve efficiency through improved production process, in order to maintainproduct gross margin. Prospective customers at the same time the cost of the production of batteries per year may drop 10-20%.

He believes that the the past global solar manufacturers too optimistic, but with the industry consolidation, will gradually eliminate the impact of over-investment, the expected overcapacity problem will be largely solved in the late 2013. Plus removal of inventory and product demand recovery, the recovery of the industry in 2014 is expected. WASHINGTON (correspondent reporter Li Jing Li Xiao-Jing Yang Bi Zhenghuai) the Xishan District ubiquitous remote mountainous the agricultural roof solar panel water heater has become a landscape. Following the 1127 sets of solar water heaters last year settled farmers, Xishan District continued this year for people in mountainous, poverty-stricken minority areas to install solar water heaters as the district government as a the seven practical one civilian, has 1774 sets to complete the installation, directly benefiting the masses 5000 people.

In September of this year, Xishan District government for unity street 1059 villagers install household solar. This year, Xishan District plans in 11 communities of the of unity, Bi chicken, Haikou three neighborhood offices, 60 resident groups, more than 200 million investment to install 1818 sets household solar the farmers simply invested one-third of all remaining costs undertaken by the Government. Currently, has been put into use in 1774 sets, accounting for 177.4% of the planned number. Comtec Solar announced after placing new way, placing 50 million shares, 1.15 yuan per share, a discount of 8% compared with the previous day's closing price, accounted for about 4.22% of the enlarged share capital of the new shares, raising net proceeds of $ 56 million, half will be used for capital expenditures, half to be used for general working capital Two explanations, self-contained solar generally refers to household use of solar thermal, solar water heater, an alternative explanation means away from the net or in situ consumption spontaneously own use photovoltaic power generation. Participants an industry analysts said the reporter, solar photovoltaic, solar thermal products as the key targets of the new consumer policy, the pulling power of the industry limitless. Domestic rural market potential has not been fully excavated, the future of solar PV, solar thermal products to enter the rural market on a large scale, will effectively expand domestic demand, recent market rumors MIIT lead organization 'PV countryside' program is a combination of promoting urbanization construction background. attendees who told reporters.

Compared to solar photovoltaic, solar cell thermal use of the industry as a whole remained stable. Sunrise Oriental (13.58,0.00,0.00%) as the only listed company of solar thermal utilization, Solar Co., Ltd., in an interview with reporters after the meeting, said Xu Xinjian, subsidies for energy is a good thing, but subsidies amount or too small, and we look forward to more to force policy and the overall health of our company is relatively stable, unlike other solar companies like ups and downs. "previously, Orient day the liter (4.550,0.00,0.00%) also posted bulletin proposed investment in Hubei Yun County construction the 20MW photovoltaic ecological agriculture greenhouses integration project. The future PV ecological integrated agricultural greenhouses

The status quo of China's solar PV market （3）

The seminar also exists another point of view. WU Fu Bao, deputy director of the China Electric Power Research Institute, Energy Research Institute, the impact of the distribution network planning and design, operation control and relay protection for distributed photovoltaic power generation, large-scale development of the appropriate measures and recommendations. However, he also said that the German distribution network load rate of about 60%, the load rate of 80% or higher, was not much room left to the solar cell photovoltaic power generation, and the roof does not have too much resources, therefore, in eastern China distributed photovoltaic power generation will not have very good prospects.

Ground-based power plants, industry legend "six six small enterprise credit support, and state and local governments direct emergency relief, Wang Haisheng, said:" This is less likely, it should be just a rumor, because the relief is greater than the industry and disadvantages Lee, more harm than good, and for Europe and the United States to launch a trade war to provide an excuse. "

Analysis of market supply and demand situation, he said, Chinese companies can contact the market (see Figure 4), taking into account the impact of Europe and the United States "double reverse", the market demand capacity in 2013 there is a big uncertainty. The supply side in the first half of 2013 may be the worst period in the industry. 10 to 20% of the GW-class manufacturers, 30% of 100 ~ 500MW-class medium-sized plant, 60 to 80% of the 100MW plant will be forced to withdraw. Expected by the end of 2013, global production capacity of 55 ~ 60GW, Chinese mainland manufacturers of production can be reduced to 30 ~ 40GW, while domestic capacity typically accounts for less than half of the global production capacity, excess capacity will continue.

Invalid expansion turn fixed assets decline, the finished products go to the inventory, a substantial increase in inventories as a result, cash flow continues to worsen, the sales drop in net profit. Therefore, the performance and profitability of the enterprises do not see signs of improvement in the short term.

But Wang Haisheng also pointed out, domestic power station development has been the core conditions, power plants began to have profitability, investment risk in reducing China Guangdong Nuclear Power in energy-saving, China Merchants New Energy and Shanghai Industrial and other large-scale central enterprises begin to invest photovoltaic power plants, the mechanism for developers out of shape the second half of 2012, part of the power solar panel plant developers will be obtained through the sale of power plants fast return on investment.

So difficult when the domestic industry, the manufacturers of any ghost of a chance should not miss and thin then small meat should eat. Golden Sun Demonstration Project, China National Energy Board website for the latest 2012 catalog of the second batch of projects, the author found that the Yingli approved projects of more than 298MW. Wang Sicheng said: "subsidy of 5.5 yuan / watt standard power projects by the user side, Yingli considerable profit. Previously, Yingli has been to follow up on the project, the big vendors such as Suntech, Astor accidentally or intentionally ignored this part ' small 'business. "

However, China Resources Comprehensive Utilization Association renewable resources special committee Secretary-General Li Junfeng, the solar planning objectives of the 12th Five-Year period is not meaningful, it's just a bottom line. In China, it is more important is that mechanism.

EU's "double reverse" big stick will fall?

Expand overseas markets, although some Chinese PV manufacturers are also investigated, and assessment of the European market and factory. But they still exist safe to assume that if the EU did not pass the "double reverse" or very low tax rates, overseas acquisitions and practices of the local plant is not necessary.

Within the EU is not a monolith, which makes Chinese PV manufacturers do not feel completely isolated. Holding the attitude of strong opposition from a number of industry associations and members of the anti-dumping. For example, the Federation of German machinery manufacturers, with many members of PV equipment manufacturers that trade protectionism will greatly hurt the local machinery industry will lead to bankruptcy photovoltaic production equipment manufacturers. Many members from photovoltaic equipment, materials, systems integration field should not be this way for the local high-cost manufacturers to provide protection Moreover, by the the protection vendor proportion not large.

Of course, the final ruling in the EU before the advent of the results, no one can under the "dual" affirmed by the conclusion. However, those parties who fans bystander. "Please have fame but the twinkling of an eye abnormalities abjection Chinese PV manufacturers must pay attention, do not be too wishful Otherwise, when the EU" double reverse "stick falls, this trusting to luck is very may allow you to pay a heavy price. Because before the United States decided to implement a "dual" measures, similar to those described above Europe firmly opposed to the "double reverse" attitude has also appeared in some U.S. industry associations and their members.

Remember Intersolar China 2011 International Symposium on the Secretary-General of the European Photovoltaic Industry Association (EPIA) Reinhold Buttgereit when I asked whether Europe will follow the example of the United States of Chinese enterprises "double reverse" survey, has been very clear that refuse The answer to this question.

The status quo of China's solar PV market （2）

Industry is facing a serious dilemma, two coping styles. Externally, the Ministry of Commerce of China following the solar grade polysilicon "double reverse" survey initiated by the EU on November 1, on the 5th EU PV subsidy discriminatory measures submitted to the WTO. Also, some Chinese manufacturers have begun to consider overseas acquisitions, local factories, and the layout of the emerging PV markets of Southeast Asia, Africa, the Middle East and Latin America regions.

Internally, the government "Twelve Five" solar panel photovoltaic power generation capacity target to 21GW, and began to actively support distributed photovoltaic power generation and grid (6MW and below capacity), 10 million kilowatts of installed 2015 target bit. Some manufacturers have already started to invest in photovoltaic power plants.

Wang Sicheng, researcher at the Energy Research Institute of National Development and Reform Commission, said that Europe and the United States, Japan and other countries and regions distributed photovoltaic power generation and grid to take the absolute mainstream, contrary to the situation in China, accounting for the vast majority, centralized.

Both he and the new energy industry Minsheng Securities chief analyst Wang Haisheng, the photovoltaic born applicable to distributed generation. High the western power station transmission costs, distributed more viable. The latest government support of distributed photovoltaic power generation is a positive attitude, and should be affirmed. However, due to the policies and regulations of each provinces reporting cap 500MW, the national total of about 15GW, a kWh subsidy of 0.4 to 0.6 yuan, may actually be 0.4 yuan. Therefore, the short-term the market will not be explosive growth. Although the policy of the government can not immediately solve the dilemma of the domestic manufacturers, "feel the burn", but to some extent can play the role of "faith sustained.

Wang Sicheng that the Chinese PV market since 2012, an average annual growth rate of 20.2% will enter a stable growth period (see Figure 2). Distributed PV generation total PV market share from 30.3% in 2011, and gradually increased to 45.24% in 2015 and 54% in 2020. China and the global photovoltaic market overcapacity situation is only temporary difficulties in the current and future years, five years later, the market demand will be greatly changed.

Wang Haisheng analysis of the optimal choice of investors in the implementation of the policy in late 2014-2015 to carry out a large-scale installation. Wang Sicheng and he and several other speeches caught distributed photovoltaic power generation investment rate of return solar cell lower than the large ground-based power plant and Golden Sun project and power station kWh subsidized prices, and the Internet part of the ability to purchase the full amount and subsidies the uncertainty of the duration, so that enterprises can not predict the return on investment is very risky, short-term is difficult to stimulate investment enthusiasm (see Figure 3). Therefore, the establishment of a stable and viable business model is the key to attracting investors.

Wang Sicheng said National Grid has issued a document to actively solve distributed PV Internet, which will make the photovoltaic industry will benefit, but there will be some loss of national grid, because it had money, and now no money. Wang Haisheng also agree with this point of view, he said: "The important thing is that the provincial and municipal grid branch has not distributed PV generation Internet included in the annual internal performance assessment indicators, so the effect is difficult to predict the actual implementation."

PV welding with high extensibility of for preventing weld failure in the bus and the interconnection between the welding zone is very important, due to the change of the temperature oscillations in the process of solar panels run extending / tension may occur such a failure. A day in the life of the solar panels process continuous, sometimes a particularly intense temperature oscillation solder joints tested during the life of the solar panels (an average of 25 years).

Two parameters critical of the most PV welding with manufacturers curvature and yield strength. Many PV welding with manufacturers, while difficult to achieve a high level welding with softness and guarantee its straightness. Get enough softness and low camber possible means to win and lose the difference between the supply contract. Manufacturers must therefore strive to improve their rolling, annealing, of tinned and materials processing technology, to meet the increasing performance requirements.

Key parameters: yield strength

The coefficient of thermal expansion of copper and silicon, the thermal expansion coefficient is different. Interconnect solder with solder about 200 ℃ silicon cells. Series welding cooling will produce bending. This may lead to destruction of the silicon crystal. Interconnect welding with low yield strength to reduce stress within the silicon cells in series welding, thus reducing scrap rates.

Using increasingly thin solar panel for welding with a lower yield strength (Rp0.2%). Just a few years ago, the 300 micron thick solar cell is also in general use. They can withstand the stress of the yield strength <120MPa welding zone. Now commonly used in the battery of 160-180 microns thick, and its mating weld with yield strength <70MPa-<80MPa. The average thickness of the battery seems to continue to look downward, to weld with manufacturers to bring further pressure to the yield strength should be reduced to 65MPa.

In order to reduce PV yield strength of the weld with the manufacturers should be looking for ways to improve in the following areas:

● Select the appropriate input copper material

● Select the correct annealing and rolling technology

● ensure accurate soldering tinned production line transport system with

● good tinned production lines in volume online actinomycetes and precise winding.

Should check their string welder the actinomycetes system, solar panel manufacturers want to reduce the stress on the battery after a series welding, to avoid welding with the hardening process of actinomycetes produce curvature. Some solar panel manufacturers have taken another solar panel design, each battery has three or even four smaller ribbons (instead of two), to further reduce the stress on the battery in the string after welding.

Key parameters: bend

Low camber placed for ensuring a straight line of the welding zone of the interconnection string welding process is very important. As the the series welding speed increases, the production of solar panels has been fully automated. Interconnect welding process used with curved large, high-yield the automatic string welder plagued by unnecessary downtime. The large curved ribbons even cause bad solder joint or string welder on rejection rate increase. The current goal pursued bend usually <5mm / m. The tighter bend degree requirements trends show that the solar cell in the future, manufacturers may be required to <3mm / m bend.

To make the minimum bend PV welding with manufacturers have to seek to improve in the following areas:

● spool winding layer precision, which requires precision mechanics structure and precise process control;

● consistent welding with quality, especially smaller overburden thickness tolerance;

● Select the appropriate size spools.

The manufacturer very clearly the limits of the spool on the edge of the smallest possible curvature of the spool at the edge welding with changing direction during placement. Spool on the smallest possible curvature depends on the diameter of the cylinder size and spools of ribbons.

However, in order to improve the welding before welding with the placement of the solar panel manufacturer or series welder suppliers themselves can check the system of the string welder Actinobacillus possible improvements. Increase the bobbin size also helps to reduce the curvature generated by the edge of the bobbin.

PV welding with of production: PlasmaPREPLATE tinned and traditional tinned comparison

The traditional copper, tinned copper wire through a molten tin / solder bath, and then in the cooling tower vertical wipe and cooling the copper after plating. Intermetallic bond only online surface clean and proper activation can be achieved. Acid wash or soak is used for the surface prior to activation of a conventional method of cleaning the copper surface, which is soaked flux. Dip flux is dirty and environmentally unfriendly process, the operator can also be detrimental.

PV welding zone is an important member of each a mainstream of solar panels are used to interconnect the solar cells and the connection to the junction box. PV solder strip is tinned copper strips 1-6mm, width, thickness of 0.08-0.5mm, has a thickness of 10-30μm solder coating. Quality of PV ribbons on the solar cell welding is an important factor to guarantee the efficiency of solar panels and persistence.

This paper glance manufacturing PV welding with market dynamics, overview of the PV solar cell manufacturers usually require welding with the nature of the product. These properties include: the material component, the size range, the straightness, flux coverage thickness, mechanical properties, and so on. Will the new tinned process of the the traditional tin plating process chemicals plasma assisted comparison, which has been widely used in the West, in Asia is also increasing. Compared two kinds Production output, productivity, efficiency, process control, and environmental impact.

PV ribbons

The PV ribbons of hot-dip tinned copper conductor used in photovoltaic solar panels. There are two kinds of PV with: interconnection with or bus bar and PV bus. In a typical silicon solar cell both is needed. Thin film solar panels are generally only bus.

The interconnect tape welded directly on the silicon crystal solar panels of the solar battery is connected to each other. The interconnection with the current generated in the solar cell to the PV bus. PV bus around the solar panels installed around the hot-dip tinned copper conductor. PV bus to interconnect with connecting to the junction box.

PV welding with market dynamics

The PV ribbons Manufacturing PV industry is a dynamic growing sub-sector. Solar panels and solar battery There are many different types, and require different types of PV welding zone (Figure 1). The PV industry is rapidly changing innovation to promote the solar panels and battery design. This leads to the performance of PV ribbons changing. PV ribbons supplier lasting price pressure, rapidly falling prices of solar panels.

The solar panels, PV ribbons is a key component, is to improve the efficiency of solar panels and the durability of the important factors (Figure 2). High efficiency and durability of the solar panels only appropriate quality PV installed solar panels welded with to achieve. The quality PV ribbons can improve the production efficiency of the solar panel and reduce the rejection rate.

To ensure the high productivity of the series welding process, it is necessary to use high-quality, very straight, soft and suitable for welding with the welding. In the series welding, the wiring process, it must also ensure accurate placement of the PV welding zone. Quality interconnect welding with string welder inevitably reduce downtime and reject rate. More demanding performance requirements of today's high-speed serial welder butt with. PV welding with the performance of the three main trends:

a) a new generation of fully automatic high output string welder increasingly stringent requirements of flux thickness and welding with a straightness tolerance;

b) the ever-thinning solar cell welding with lower yield strength (Rp0.2%);

c) The new solar panel design uses each cell three interconnect welding zone in order to replace the two welding zone, which reflects the requirements of the welding zone for smaller (narrower and thinner) growing. This in turn promote the for small interconnect welding with precision tinned production line capacity expansion.

Performance of PV ribbons and requirements

PV welding with the conductor or the base material is a high rate of high conductivity copper (Figure 3). The copper for PV welding zone Usually ETP, DIP in the form of copper or oxygen-free copper (OFC: CD-110, CD-101, the CD-102).

Copper wire wound in a rolling mill in production of copper strip, and then tinned online tinned / plated flux. Some manufacturing production Copperbelt commercial alternative to copper strip slitting process, its quality is generally low.

PV bus bare Copperbelt (tinned inlet material) of the production line, size is a width of 3-6mm, a thickness of 0.2-0.5mm. Welding with the interconnect, the size of the bare Copperbelt is wide and 1-3mm, a thickness of 0.08-0.2mm.

Copperbelt tolerance with the manufacturer. They are mainly depends on the type of rolling mill, the quality of the input material and the manufacturer's process know. Here is excellent rolling capacity typical manufacturer's tolerances: (a) Width tolerance: ± 8μm ± 15μm; (b) thickness tolerance: ± 8μm-± 13μm.

The PV solar panel makers usually seek the mechanical properties of the ribbons is:

● Tensile strength: <250MPa

● Elongation:> 20%

● bend: <0.5% [1m long sample on 5mm]

● the yield strength (Rp0, 2%): a) hard> 120MPa; b) soft <80MPa; ultra-soft <65MPa

The PV ribbons the straightness (also called bend) is based on the sample of one meter long ribbons measured a few millimeters away from the straight line. Maximum camber is determined by series welding process, and generally in the range between <8mm / m <5mm / m.

PV used in welding with a flux composition of many different types. They depend on the the series welding technology and solar panel manufacturers to develop local manufacturing of solar panels health and safety standards. The common flux components including lead-free solder (Sn 100), leaded flux (SnPb 60/40), with silver solder (SnAg 96.5/3.5; SnAgCu 96.5/3.0/0.5), leaded silver solder (SnPbAg 62/36 / 2), low-temperature solder (BiSn 57/43, BiSnAg 57.7/42/0.3). The flux covering thickness range is 10μm-40μm, tolerance of ± 10% - ± 30%. The most commonly used solder clad thickness is 20μm ± 4μm.

The flux covering thickness measurement method, there are three. X-ray method is for one-sided thickness measurements of off-line measurement method. Manual micrometer is used to measure the total thickness of the covering layer 2 surface of the off-line measurement method. A laser thickness measurement apparatus are commonly used in the online measurement, can be used in the tin production line for the production process of the PV welding zone measuring coverage of the total thickness of the two faces.

PV ribbons can also use the naked eye or microscopic examination covering quality, there should be no defects such as stains, debris, dents, discoloration, visible through the flux covering bare copper, small pinhole, and other mechanical defects.

Welding with standard introduced in August 2011, the PV of the most performance indicators and measurement methods provided. Www.semi.org these standards can be obtained on the site, including (a) SEMI PV18-08111 and (b) of SEMI PV19-08112.

PV finished loading the spool / reel or disc. In Europe, the most commonly used PV ribbons spools DIN K125, K160, K200 and K250, and in Asia with a P4 and P10.

The accumulation of multiple positive solar energy

The global PV industry is facing the cold of winter, a large number of Chinese solar PV companies listed in the United States, the price is a record, the four companies were delisted warning. However local time December 12, stimulated by the good news of a series of industry fundamentals appear two or three percent surge in solar stocks collective. Hebei two listed companies Yingli Green Energy and JA Solar, also there has been a rise of nearly 20%.

Hebei prices rose two percent

Beijing time yesterday morning, Yingli Green Energy (Baoding Yingli Group's listed companies) surged 18.23%, to close at $ 2.14, the market capitalization climbed to $ 327 million. In after-hours trading session of the New York Stock Exchange, Yingli continue to rise slightly.

Ningjin Jing Long Group listed company, JA Solar, 12, 2009 the rate of increase of 19.65%, closing at $ 4.08, its market capitalization was $ 200 000 000.

It needs to be pointed out is that JA Solar is listed on the NASDAQ stock market, after the share price for 30 consecutive days to less than one dollar by Nasdaq delisting warning. JA Solar to select "one" of the partnership program. After the partnership after its stock price of $ 4, has been away from the one U.S. dollar mark.

Reporters rough calculation found that solar stocks a surge in the 12th, two listed companies in Hebei about increased nearly 90 million U.S. dollars (about 560 million yuan) of the market value.

Nearly 32% of the maximum increase

See the day Yingli, JA two or also only talk about midstream by the U.S. stock market data. In other listed Chinese stocks, ReneSola soared 31.69%, the same day or maximum company.

Sunergy rose 20.44%, the big new energy companies rose 31.25%.

Suntech Power and Yingli, JA two companies belonging to the first group in the world, up 10.54%, LDK solar cell  LDK rose 15.38%, Changzhou Trina Solar rose 10.26%.

Ministry of Finance New subsidies

Solar stocks drought every Kam Yu "What is it? Reporter has learned, the boom of the day and not only the motivation, but recently more good news superposition results.

Among them, the official media reported on the 11th, in order to foster the domestic photovoltaic industry, the Ministry of Finance recently allocated 70 billion yuan of funds to support additional 3.2 GW in the domestic photovoltaic demonstration project.

Ministry of Finance data, coupled with the beginning of the year allocated 60 billion to start the 1.9 GW in 2012, central government allocated 13 billion yuan of funds to support the total size of 5.2 GW to start the domestic application of photovoltaic power generation, greatly promoted the domestic PV application demonstration.

Ministry of Finance, the person in charge, based on a combination of factors such as the cost of investment, the award criteria to determine subsidies for the user side of the photovoltaic power generation projects of 5.5 yuan / watt, independent photovoltaic power plants and household system subsidies of 25 yuan / watt and 18 yuan / watt, effective mobilization of investment enthusiasm of photovoltaic power plants.

Another multiple positive

In addition to the Ministry of Finance New subsidies, the recent news that the National Energy Board may be released prior to the development of solar power, "the 12th Five-Year Plan" to modify, double the solar power installed capacity target for 2015.

In October this year, the National Energy Board in the official website officially announced the development of solar power "Twelfth Five-Year Plan". Reporters see in the "planning" in 2015, China's solar power generation capacity will be 21 GW of generating capacity reached 250 million degrees. By 2020, the total installed capacity will reach 50 GW.

Hebei photovoltaic industry told reporters before the release of this plan, the industry is expected to "Twelve Five" installed target has been raised to 40 GW, so some of the industry but the ultimate target of 21 GW of disappointment, do not rule out the National Energy Board according to industry voices, raised the capacity target, thereby expanding the solar power market in China.

Most of the enterprises of the solar panel energy takes stock battery plate manufacturer. According to the reporter, the recent domestic polysilicon continued to fall, fell to 110 yuan per kilogram, has fallen by half distance early. Polysilicon is the raw materials for manufacture of battery plates, prices plummeted, means that the cost of the solar panels manufactured to drop.

In addition, the Ministry of Finance, the Ministry of Science and Technology and the National Energy Board has announced the second batch of Golden Sun demonstration project directory in 2012, installed capacity of 2.8 GW of Total passed photovoltaic projects, which means that domestic the photovoltaic manufacturing enterprises will get more of Golden Sun demonstration project orders.
