In terms of industrial or manual building, the Swiss professional association Swissolar but confirmed that few phenomenon of the farmhouse to install solar panels and even started to decline, the association said, use of solar energy decline is due to the current encouraging mechanism is blank. Upside down to two pipe system content is for reference only. Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation 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. However, the expert inside course of study thinks, far from its potential development. Upside down to two pipe system Swiss solar power industry's annual turnover of about 8. 6. 5 billion francs: 7. 500 million light volt generating, 1. 1. 5 billion come from the sun's heat. In Switzerland, in order to promote the photoelectric, and other renewable energy, by paying higher prices, every consumer must do an own meager power, according to the law, they pay per KWH of electricity ( Known as per degree of electricity) Should not be more than 2. 3 centimes ( 1 the Swiss franc = 100 centimes) , which proceeds to provide economic support for the users who install solar devices, although the current application is far beyond the budget. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information. Swiss solar professional association Swissolar pointed out that according to the statistics at the end of 2018, about 85000 Swiss photovoltaic power station, with a total installed capacity of 2173 megawatts, Swiss photovoltaic output of 1. 9 trillion watts, covering the area of 13 million square meters of solar panels, size of 2000 football pitches. Federal energy office think, transparent solar glass on the roof of all buildings and outside wall installing solar panels to absorb sunlight, Switzerland annual output power could reach 67 trillion watts. Solar light power projects in particular, transparent glass in the wide development of 410 mw, 603 mw nuclear, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw2018, Switzerland for the consumption of electricity has 3. 4% come from solar energy, solar energy in Switzerland is second only to hydroelectric power of the most important renewable energy, solar stent certification light hydro power generation project for Switzerland provides 60% of its energy needs. If the mountain roofs, roads and parking lot ( Such as ski resort) Taken into consideration, can also be more power 15 trillion w, the Swiss solar professional association Swissolar claims that by 2050, photovoltaic and other renewable energy development can make Switzerland 100% rely on clean energy. Solar photovoltaic net news: news, November 4, photovoltaic power generation in Switzerland is second only to hydroelectric power of the most important renewable energy. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in project bidding and parity, the state-owned enterprises have become the absolute main force. Today, Switzerland has become one of the top countries in the field of solar energy the most innovative. However, compared with European average solar power generation, the Swiss have to candidly admit defeat. Since 2010, the solar energy in the national electricity consumption and the proportion of stable rise. In 1982, the Swiss became photovoltaic power generation will connected to the grid of the first European countries. Solar pv projects compared with a few Mediterranean countries such as Spain or Portugal, Switzerland's solar power generation. In Switzerland, almost all of the solar panels were installed on the buildings, and its neighbors will these facilities installed in open field, the difference is attributable to the Swiss corresponding shortage of place, the high cost of examination and approval and the local population's conservative ideas. Last year, the installation of photoelectric facilities especially in single-family homes ( Relative to the increased by 17% in 2017) And multi-family housing ( Growth rate of 47%) Areas have made progress, Swiss solar professional association Swissolar pointed out that the benefits from lower the product cost and integrated optoelectronic technology progress: now, pv panels has become covered building roofs and walls of an element, solar pv projects this also provides convenient conditions for their use.
