Stagnant demand in the global PV market , the vast majority of the solar device manufacturers are responding to the declining profitability of the unfavorable situation, but there is a field of industry chain is very small losses that PV inverters .

    With solar cells and panels of different manufacturers , PV solar power inverter manufacturers did not how by increasing competition and economic downturn. Solar inverters complex structure, make it difficult to maintain the relative price is also relatively stable .

    Analysts said the market size of the inverter reach 60 billion U.S. dollars, subject to overall adverse environmental effects , the PV inverter margins will be reduced , but no other areas of the industry chain the decrease so much. A solar power generation system usually consists of photovoltaic solar panels and inverters composition, the former is used to generate electricity , which convert DC to AC power available .

    By overcapacity , fierce competition and government subsidies continue to enhance the degree cuts affect , solar cells and solar panels prices have been declining. Carlson Renewable Energy Fund manager Jon Sigurdsen said: "For an inverter companies, interior design products more , although the production of an inverter is very simple, but to do a good inverter is difficult. This it means to enter this field have a higher threshold for the industry , but also beneficial to maintain high profit margins . "

    " Better " is not meant to "perfect the ." Last month, the world's largest PV grid tie power inverter manufacturer SMA Solar lowered its full-year earnings forecast , U.S. rival Power-One also this week lowered its third-quarter earnings outlook.

    Now, with the difference in quality solar panels increasingly smaller , the brand has become less important ; while in the field of solar inverter , technology and brand awareness there is conducive to product sales. Keen on solar cells and modules Asian companies are rarely involved in the PV inverter .

    IMS Research senior research director Ash Sharma said: " China suppliers control 40% of global solar module market share, while the market share of the inverter is only 5% , and the growth rate is relatively slow ." Number of competitors than also help prevent small price decline. Although there are more than 150 global PV inverter suppliers , but the top 10 companies control 75% of market share.

    So far this year , the price of solar panels has fallen by 40 %, but the retail price of PV inverters fell only 10-15%. Entire solar panel solar power system costs accounted for about 40% , while the proportion of solar inverter is 15% occupied .
