The article content is for reference only. Visual pv modules terminal product prices this year has been largely to the end, as the transformer substation voltage grade nine project gradually starts in October, the component will be in short supply, steam generator principle possible rebound in small increments. Virtualization technology advantages and disadvantages of single crystal price trend of photovoltaic modules is estimated to last a week or two. Virtualization technology advantages and disadvantages in joining in power plant to join the world of the photovoltaic power station which is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, heat exchanger specification table wide-ranging, can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, solar photovoltaic (pv) network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. Polycrystalline silicon slice of today's price of solar photovoltaic (pv), a single crystal PERC battery prices dropped more than 20% in June, compared with that in substation voltage grade for ten weeks after the price last week finally falling, photovoltaic battery again this week to cut a penny!
