"The solar cell module is about to usher in a big change for us, it will have a lot of business opportunities." This statement is issued by Texas Instruments (TI) is responsible for the solar cell related business Dave Freeman. Freeman in May 2009 set up a specialized solar cell business team, the author on the future trends in the solar cell industry was carried out interviews.

The original plurality of solar cell modules in series, and then connected to the inverter. Therefore, there is uneven and if a result of sunlight as a result of the output characteristics of unequal power down module, overall output power will be significantly reduced.

To solve this problem, each solar cell module in the future may be equipped with the inverter and converter function. This is called "micro-inverter" and "micro-converter." So that each module can be achieved by optimizing the output power, the overall maximum output power. In addition, a combination of communication functions, it can also be used to monitor the state of each module to detect the faulty module.

Micro-inverter is equipped with all the various modules available on the inverter functions. That is, the optimization of the output power from the DC-AC conversion performed by the module. The power output from the module for the exchange, can be directly connected to the grid. Because construction is easy, therefore the installation of residential and commercial facilities should have a business need.

Mini-converter for each module to optimize power output and DC-DC converter, the rest of the DC-AC converter is set by another inverter is completed. Miniature converter positioned in the existing micro-inverters and inverters between. Since the power output of the solar cell module is DC, it can be generated directly to the current state of power used to charge rechargeable batteries. Unpowered wireless communication base stations and other areas not connected to the grid independent facilities such demand exists.

In addition, there may be a large demand for solar power stations. How the presence of large-scale solar power plants in a huge number of solar cell modules to identify the faulty module problem. And is equipped with a micro-chip control and communication converter will help to solve this problem. Because micro-inverter price is higher than mini-converter, it is difficult to import a large solar power stations.

Universal micro-inverters and micro-converter which currently exist difficulties? Difficulty lies in the costs of conversion efficiency and reliability. From the current price of view, the existing inverter is 60 cents / W, while the micro-inverter  http://www.gridtiepowerinverteronline.com/ to $ 1 / W. If you can achieve the same level the following, we hope to achieve universal access. The conversion efficiency of the inverter section, the objective is to achieve a considerable existing inverter 98%. The reliability of the solar cell module will have quite reach to the level for 20 years.

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