In 2010, the PV inverter industry, the utilization of rapid gains disruptive technologies , micro-inverters and power optimizers , shipments grew more than 500%. But they still only account for PV inverters less than 1% of total revenue . Out mostly concentrated in a small volume of some of the suppliers among companies such as Enphase and SolarEdge , respectively, in micro-inverters and DC-DC power optimizers success on the market , and is currently active in the market of suppliers have more than 20, and the market is expected to grow at an annual growth rate doubled and continued until 2015 .

IMS Research expects micro grid tie inverter and power optimizers market value by 2015, more than 1.3 billion U.S. dollars . Until then, mass production can be achieved through an OEM agreement , the price of these breakthrough technologies will be significantly reduced. However, by 2015 , the average price of micro-inverter is expected to still be higher than the traditional 50% of the inverter , so the market penetration will be limited to about 6%.

Increasing the amount of supply and declining prices will drive these two ground-breaking technology. IMS Research 's PV market analyst Tom Haddon said: "The groundbreaking technology , such as off grid inverter and power optimizers claim to be able to bring many advantages, including greater gains , easy installation, and security and to improve monitoring of .

But their prices are high, and the market is relatively immature , limiting their development , especially for non-residential installation system . Outside North America , the development of micro-inverter penetration is very slow , because Europe's installers still prefer the string inverters . "

Although the development of the new inverter market in its infancy , but there are several factors that may promote or hinder its development. Some micro-inverters and power optimizers suppliers is actively consult and cooperate with component suppliers , providing component integration solutions. By 2015 , 45% and 40% of the micro-inverter power optimizer will combine with the component .

Tom Haddon said: "By working with component suppliers , micro- inverters and power optimizers providers can get a huge customer base and established sales channels , providing customers with better prices , while also providing for the component suppliers differentiated products . "
