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engaged in new energy or a review of the photovoltaic difficult development, at present, China's shenzhen bus has been replaced by electric motors. Solar photovoltaic (pv) net news: in order to protect the environment and save energy, heat source system principle at the bottom of the wardrobe up how many countries in the world started to will begin the public transport system from the traditional fossil fuel engine to electric motor. Bus USES electric motors have begun to gradually popular, dual computer hot standby software which good but is not a train in the world the use of electric motor. 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, heat storage system does not mean that agree with his point of view or confirm its description. It is reported, this is the world's first solar-powered railway, although say 100 solar panels relative to the whole electric power system is small, but that this is a huge achievement for the world, it may be for the global various countries have adopted similar solar lines provide template. According to foreign media reports, the power plants with a total of 100 solar panels, the solar panels will be for the railway itself as well as the railway signal supply power and light. Britain is currently conducting the study. It is reported that the British hampshire aldershot near a railway line plan implementation completely by solar power - Near by a solar power plant. The article content is for reference only. '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, heat storage system can meet the needs of different readers.
