In the new energy industry, the photovoltaic industry has become a bright star in a short period of time, formed a complete industrial chain, led the development of a large number of upstream and downstream enterprises. China's photovoltaic power generation technologies and applications only at the lower level position in the world, and its essence but also due to the basic raw material in the photovoltaic industry - lack of polysilicon purification technology, which directly led to the high cost of domestic photovoltaic power generation, it is precisely because For this reason, the photovoltaic power generation can not be widely available.

In the upstream industry chain, the PV inverter core technology has reached the world level, a number of inverter enterprises gradually expose edge in the international market. Nevertheless, domestic inverter, but still can not embark on the road of internationalization, China inverter always have an advantage in terms of price, but overall the entire solar inverter system costs only 7%.

Reliance on local products to local customers thinking largely crowded out foreign companies and local companies may be on product performance and price are slightly inferior to foreign products, one chip, but after already prejudiced in the minds of customers have formed a local brand. China's enterprises in order to further the inverter market, we must first make the product popular, breaking customer conventional thinking.

And the crucial components inside the solar inverters selection, quality and conversion rates as expected, it is necessary to ensure the stability of the product, to establish a stable relationship with an excellent component suppliers can not be ignored, and the current domestic inverter element Device selection mostly lack of internationally renowned supplier of the product in the eyes of foreign customers will be greatly reduced.

Meanwhile strong R & D team and whether or not the level of product technology is also blood interlinked, as part of the electronic products industry, stable or not, and the conversion efficiency of the PV inverter also requires a strong level of technical support.

Looking at the international brand products, their R & D team is undoubtedly the top, it also ensures the product quality. And because many companies lack the relevant offices in foreign markets, so that the service is the lack of advantage, while, products and market development will not localized, low trust in the minds of local customers. China inverter companies should do is to adopt a strategic cooperation model with local upstream and dow

 IHS Research report shows that the global PV inverter buyers, is the fastest growing storage needs. Although the technology is still relatively immature, but IMS Research for the global PV inverter four hundred customer survey showed that nearly a third of respondents expect that by 2015, over 40% of the solar energy system installed to enable them energy storage technology.

Germany, Italy and the UK respondents emphasized that the future of photovoltaic inverter http://www.gridtiepowerinverteronline.com/ , the energy storage is more important than any other needs. When asked about the use of the main factors driving forces storage of customers' most common answer is to reduce the price of the battery, which helps reduce system price, so that the storage economically viable.

More than 60 percent of respondents said the system price includes energy storage technology to improve 10-29% is "acceptable", although nearly a third of respondents said they are ready to pay a higher premium. IHS Power and Energy Research Manager Sam Wilkinson (Sam Wilkinson), said: "For photovoltaic systems, energy storage is becoming more and more important, if the supplier can deliver the product in line with industry expectations, photovoltaic energy storage market can remarkable development over the next two years. "

The survey also asked customers about their using micro grid connected inverter, display relatively high price of this technology to become a widespread disorder. But the survey also revealed that in 2012 compared to 2011, compared to enable micro-inverter proportion of customers has increased by ten percentage points. Respondents stressed that they have the ability to fight the effects of occlusion, additional design flexibility using micro inverters become the most common cause.

Wilkinson said: "Due to the advantages and features they provide, micro inverters are becoming more widely accepted, but the price to make a major disadvantage, the majority of respondents micro-inverter is not currently represented purchases For them, the need to reduce the price by more than 50% before considering they enable.
