'Photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic solar photovoltaic glass now and the past and the future development of summary corpus, wide-ranging solar photovoltaic glass, can meet the needs of different readers. And the value of polycrystalline is no obvious change. 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) net news: on October 8, 2019, guangzhou development energy released its photovoltaic modules for 2019 ~ 2020 primary supplier. The bidding documents and bidding and the original text is as follows: solar photovoltaic 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. Solar controller application form can see, compared with the price in single crystal components guodian voting at the end of August 3 gw components in price ( 1. RMB 777 / W) Will still be lower, the lowest price only is listed as alternative suppliers. The tender will be divided into three blocks, investment scheme that single crystal components (graveyard More than 370 w) , polycrystalline components ( More than 335 w) Single crystal double double glass, photovoltaic industry study with borders three blocks ( More than 360 w) 。 The article content is for reference only.
