The difficulties to popularise micro-inverter and micro- converter and its business opportunities




The challenge is cost, conversion efficiency and reliability. Judging from the current price of view, the current power inverter for 60 cents / W, while the micro-inverter to one U.S. dollars / W. If we can achieve the same level below, we hope to achieve universal access. In the inverter part of the conversion efficiency, the goal is to achieve with existing inverter considerable 98%. The reliability of solar cells and modules will have to very, reaching a level able to work for 20 years.



If these difficulties can be resolved, shipments will be expected to exceed the current inverter. ISuppli forecasts the United States, the original inverter shipments in 2012 of 130 million to 1.4 million units, while the micro-and micro-inverter converter total shipments in 2012 will reach about 800 million units. Currently the U.S. has been the risk of micro-enterprises and other enterprises and micro-inverter converter start development.



In the current inverter, power semiconductors for power conversion feature is particularly important. In the future, apart from power semiconductors, the power output of each module to optimize the control IC, as well as the delivery status of each module the importance of communications IC will also be increasing. The control IC and communications IC is our area of expertise.



In addition, in the future will also promote collaboration with the smart grid. We have also committed to smart grid areas, to make use of experiences in this regard.



We had also engaged in solar cell chip business. As a result, the use of existing solar inverter control IC, access to about 30% of the share. However, there was just one of many applications as solar cells.



May 2009 be configured to engineers responsible for solar cells established a working solar cell system. It also hired experts in solar cell technology. This is because the technology with customers to solve the problem, is very important. But also helps to understand the characteristics of a variety of solar cells on the difference. In the solar cell outside the field of technology experts, we have not yet configured.
