In the next three years, China will continue to dominate the 分類: 未分類

 Series of anti-domestic photovoltaic industry experienced a debt crisis, "double reverse" is some positive factors: on the one hand, the context of the country to support the photovoltaic industry has become increasingly clear; On the other hand, with the consolidation in the industry, the tide of incoming serious imbalance between supply and demand in the market conditions will probably be the difference after the Ebb Tide. 


Boston-based market research firm GTM Research the latest research report pointed out that, after the consolidation in the industry, to 2015, nine of the world leading solar module manufacturers list, Chinese companies will continue to occupy seven seats. However, the two leading Suntech and LDK Solar is not one of them. 

Although the United States has been the Chinese photovoltaic products "double reverse" the final ruling, the EU has also followed ', but is still better than the days of the local PV companies. Recently, there are a lot of overseas 
power inverter PV corporate bankruptcy or cut the news came out. 

North American photovoltaic inverter maker Satcon Technology this week announced that the request has been made to the United States Delaware court bankruptcy protection under U.S. bankruptcy law. 

Previously, it was the world's largest manufacturer of photovoltaic cells in Germany Q-cells also filed for bankruptcy to the court. Berlin manufacturer of photovoltaic cells Solon German power plant manufacturers SolarMillennium has closed down in December last year. 

Another photovoltaic famous enterprises SunPower announced the day before yesterday, the photovoltaic market downturn, the company will cut six of the 12 battery production lines idle in the Philippines, while a 20% reduction in capacity, will also be laying off about 900 employees. 

GTM report pointed out that the 
grid tie inverter PV modules of the solar industry is still excess capacity, is expected in the next three years, the average annual production capacity will exceed demand 35GW. Low-cost silicon material, the price war, the withdrawal of government funding, and the market needs to stabilize the industry consolidation continues. 


The agency analyst forecast to 2015, excess capacity and low prices will lead to the existing 180 component manufacturers took to the road collapse or takeover.Currently, manufacturers of the most costly in the United States, Canada, and Europe, with China's cheap solar panels, its difficult to high. 

The agency is also expected from China, 54 180 "ill-fated" enterprise. The Chinese government will continue to provide financial support to enterprises with a large number of employees, to repay short-term borrowings or encourage diversified industrial giant acquisition of these enterprises. Potential beneficiaries of these strategies, including Trina Solar, Yingli Green Energy, Suntech, JA Solar, JinkoSolar, ReneSola etc.. The total capacity of these enterprises accounted for more than 20% of the global total capacity. 

However, Mehta said, so far, the small degree of integration of photovoltaic manufacturing sector of the industry as a whole continues to overcapacity mitigation efforts. PV supply chain profitability remains challenging, unless made in China, capable of substantial rationalization. 

A photovoltaic industry who also believes that the key step is the Chinese 
solar panel PV companies to bail out the domestic photovoltaic capacity of survival of the fittest."Currently, many areas of local government and local PV companies has become a community of interests, or even alone who kidnapped who question, but the consequences from the normal logical enterprise survival may not function properly bankruptcy. 


The other hand, Europe and the United States, abound photovoltaic enterprises to seek bankruptcy protection, the market is the internal mechanism to support industrial development of core strength. "The source said." The way forward is still full of casualties. From 2012 to 2014, we estimate that at least 60% of the existing PV suppliers will be forced to exit the market. Mehta said, "comprehensive variety of factors to consider, we expect everything from the 2013. ' 

In his opinion, the demand for solar energy supply chain is likely in 2014 tends to balance. The GTM given a 2015 nine leading PV manufacturers forecast List, including Artes sun power FirstSolar JinkoSolar Trina light and so on. 

However, has the world's largest manufacturer of photovoltaic cells and the world's largest silicon manufacturer Suntech Power and LDK Solar is not in this list are.

Inverter Expert Power-One European sales fell 32% 分類: 未分類

 The report of the the PV inverters experts Power-One, fourth quarter revenue of $ 192 million, the modified target, but European sales fell 32 percent, forcing the company to adjust production plans to lay off three hundred people. As mentioned earlier, although the Asia-Pacific revenue also declined in Australia's third-quarter seasonal decline in the strong, but due to the modification of the feed-in tariff subsidies lead to lower-than-expected demand in Germany and Italy, which is the main reason for declining revenue. The company said that, based on the needs of the residential and commercial markets for the group of string inverter, sales in North America increased. 


The report of the Power-One grid tie inverter in the fourth quarter of 2012 shipments of 628MW, annual shipments to 3.6GW, representing a 23% increase over 2011.Renewable energy solutions sector sales of $ 123 million, operating loss of $ 8.5 million. 

However, the management to discuss quarterly results conference call that, in the beginning of the fourth quarter, the company laid off three hundred people, accounting for about 3% of its total number of employees, mainly from its manufacturing operations, reduced to "right size" "match changing demand environment. 

Due to the competitive environment, weak European demand also led to higher-than-expected decline in average sales price. The fourth quarter decline in average selling prices remained at a low level, and forecast double-digit decline in 2013. 
The company reported that fourth quarter gross margin was 13%, compared with a decline in the gross profit margin of 29% in the third quarter. 

From a geographical point of view, Europe, Middle East and Africa, 76% of the total revenue, of which 28% came from Italy, 17% from Germany, 31% from other regions. 9% of the total revenue in the Asia-Pacific, North America accounted for 15%. Although the restructuring, but the management of the Power-One, they estimated that the North American market in 2013 is expected to grow by more than 40%, due to the large commercial and utility-scale industry remains strong. The company claims that the residential string wind inverter accounts for about 20% of the market share, but accounted for less than 10% of the overall market. 

Management also stressed that the Chinese market, the continuous development of utility scale sector driven. Pointed out that it will be concern the EPC and public utility companies, the establishment of the company's business in China through a partnership with Phono Solar (PhonoSolar), Power-One. The company also forecast the creation of a strategic alliance in order to enter the market in 2013 in Japan

(RichardThompson), Richard Thompson, president and chief executive officer of Power-One, said: "In India, the government continued to provide solar energy policy to support, estimated that in 2013, the solar installation project will almost doubling in India, 2012 years disappointing for us, especially considering that the initial success we have achieved in 2011. " 

Management said its forecast that the European market in 2013, or a decline of about 24%, fell to 12,000 MW-13, 500MW in 2012 to 16,800 MW. 

German market is estimated to be in the range of 4,200 MW-4, 800MW of, down 42% compared to 2012. However, in 2013, it is estimated that the Italian market will decline up to 49%, PV installed capacity is estimated at 1,800 MW-2, 200MW of range.
