This year, according to GTM Research Research, will use 1500 v technology to build up to 4.6 GW pv systems, made in 2016 a large-scale deployment of the technology of "stepping stone".

With many components and other parts maker announced the 1500 v products, solar industry to realize the importance of the 1500 v system growing can be said to be one of the major trends in 2015.

Now, in view of the supply chain seems to catch up with the trend of the higher voltage, GTM research thinks, the industry ready to use this technique as the general standard of public enterprise scale system.

GTM research report of the 2016-2022, 2016 v pv systems and components: cost, supplier and expected "predicted that the 1500 v system will account for about 9% of the global pv demand this year, equivalent to about 4.6 GW.

According to GTM research analysts and the report's authors Scott moscowitz (Scott Moskowitz), that in itself is a milestone in 2015, the 1500 v system accounts for only part of the demand is very small. But this is just the beginning, the higher the voltage make replace 1000 v utility system standard.

Moscowitz said yesterday in an interview with PV - Tech, said: "remember 4.6 GW is definitely a market development trend of a stepping stone. We reported number is 4.6 GW, this year 9.2% of the global public demand, it is still a relatively small amount."

"We believe that once in 2016 proved that the 1500 v system, the value proposition of appropriate supply chain is complete, developers to build these systems, compared with the 1000 v system to save money, 1500 v will be almost worldwide utilities scale system default technology choice."

Moscowitz said, adding that the industry focus on the transformation from a standard 1000 v to 1000 v, a few years ago, there has been a similar shift - from 600 v to 1000 v, some companies, especially in the United States.

He said: "in the United States, 600-1000 - v shift off guard. Many firms are not expected to happen so quickly, slowed with the pace of the 1000 v products into the market. So the people try to don't be the last one, for the arrival of the 1500 v system requirements given great attention, and ensure that they are ready."

Moscowitz said that so far the supply chain and the limit of the limitations of all people to take 1500 v technology, apart from a few pioneer company, such as First Solar Belectric Europe and the United States. "However, these obstacles is resolved soon, and as more and more lay a foundation composed of higher voltage systems market."

Moscowitz added, last year, many component manufacturers announced that the 1500 v products, is expected to find their own market in 2016. Since then, once the industry saw reduce overall system cost, higher voltage 1500 v will become the dominant technology.
