"Second five" first year, PV development has a special meaning in the history of the year, but also the year of the change in the situation of the photovoltaic industry, the competitive landscape. In recent years, the domestic and international energy giants have competing solar photovoltaic power generation, new energy investment is one important direction. The 2011 PV winter warming With the quick opening of the domestic PV market, the core of the device as a solar power system inverter market demand. 

Inverter, also known as the power regulator, the power adjustment means is composed of a semiconductor device, mainly for converting the DC power into AC power. PV inverter can be divided into high-power inverters and small and medium-sized power inverter. 
Still general consulting electronics industry analysts believe that the inverter as a core component of long-term stable operation of the impact of PV systems, PV companies want foothold in the highly competitive international market, we must strictly control the development cycle to protect product quality. 

Currently, some domestic photovoltaic inverter enterprises to reduce R & D links to purchase the drawings produce products quickly enter the market, while the lack of research and development aspects of the manufacturing enterprise is bound to face a double test of the technology and product quality. 

Europe is the first rise of the global photovoltaic wind charge controller technology is a world leader. China's solar the terminal market starts late, the smaller domestic PV inverter manufacturers. At present, the domestic manufacturers to enter the field more small and medium power inverter, technical level and foreign manufacturers at the same level, and building fast due to the production of domestic enterprises, relatively low labor costs, small and medium power inverter competitive advantage, but the threshold for high-power inverter technology is much higher than the small power inverter, there is a big gap between the high-power domestic PV inverter technology, performance and stability with foreign products. 

Still general consulting released "2011-2016 China inverter market analysis report shows that, in order to maintain growth, companies must focus on certain areas makes the inverter. Solar adjustment of national policy, the European market growth will slow, and the new markets of the Americas, Asia and Central and Eastern Europe will provide more opportunities for the expansion of the market in recent 

Germany's largest solar PV inverter companies SMA by Asian competitors price challenges and equipment prices plummeted, and the company's market share in 2011 dropped significantly. SMA, 2010 in the global grid tie inverter market share of 40%, down about a third from 2011. 

SMA's market share will decline further this year, the reason may not be able to further open the huge potential of the Chinese market. Western Solar Group accused the Chinese government of "illegal" subsidies to domestic firms and markets in Europe and the U.S. dumping cheap solar cells and modules, SMA Chinese market and can not be too optimistic to predict. And is nearly 40% of the global inverter market of 300-400 Canadian small business, including over 200 Asian companies. German SMA has been to compete with Schneider Electric and Siemens have asserted in the past, small businesses from Asia will be a significant competitive threat, now is indeed true. 

Over the past year is widely considered the young solar industry is the worst ever year, government subsidies decline, prices plummeted, and low-cost competition in Asia has forced some solar companies went bankrupt, which of course also includes Germany's Solon and SolarMillennium directly leading to SMA dividends and profits is less than half of the expected. SMA company has announced in the January 2011 preliminary earnings report, the 2011 net profit reached 166 million euros, to the EBIT (EBIIT) more than 240 million euros.
