'Photovoltaic (pv) of the world' this is a comprehensive system to introduce the development of photovoltaic (pv) in the past, present and future the sum of the corpus, wide-ranging, can meet the needs of different readers. Local is laid on the Thule lake floating solar panels, the panel station is made up of 36 barge, a total of 2240 square meters of solar cells will be placed, the goal is to transport 800000 kilowatt-hours of electricity every year, the equivalent of about 220 households in power consumption. The article content is for reference only. Gas plate heat exchanger in this paper, not only including the 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, chest back with 3 mm including global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, solar photovoltaic (pv) net news: local time on October 8, 2019, the Swiss Bourg - 圣- Pierre, workers in the mountain lake reservoir Thule lake ( Lac des Toules) Assembly with solar panels on the barge. Chest back with 3 mm photovoltaic solar power network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar photovoltaic (pv) network published the article for the purpose of the information, done polysilicon artificial broken heat exchange technology does not mean that agree with his point of view or confirm its description.
