energy is the human society development and the key drivers of economic growth mode transformation. Since the 18th century, humanity has experienced the industrial revolution and the electrical revolution. From the first time the industrial revolution, coal makes the engine to start, make the UK a empire of the sun never sets. The popularity of oil, especially the connection between the oil and the dollar, to defend the us dominance in the world. This led to the formation of the global solar power market. This industry, under the long-term elaboration of the government and environmental groups, and finally became a rapid rise in 2016, the global industry. China is the leader and main beneficiaries of the new industrial revolution. The energy problem has been the world matter of concern to health and environmental professionals. In China, related government even to investing in new energy. However, the energy problem is more difficult. Later, someone put forward the concept of photovoltaic (pv), in fact, photovoltaic (pv) since there was the attention of the governments, countries also spend a lot of money. However, any industry may face difficulties in development, photovoltaic industry is no exception. In 2011 and 2012, when the photovoltaic industry in the most difficult period, capital and industry are more or less different. When they need it most, capital relentlessly to leave, to stop lending, to cut off the loans and withdraw loans. At present, the industry is experiencing another round of prosperity. We may have to work hard to establish a long-term sustainable industrial ecology. If the industry in a few months a new pessimism and they will come together and rational view of the photovoltaic (pv), have a better future. Photovoltaic market development is rapid, distributed power plant more and more get the welcome of friends. Construction of photovoltaic power plants on the roof seems to be a trend. However, when the roof power stations and urban management department to meet, they inevitably marked by 'illegal'. So, how can we escape the fate of the violation of rules? I must know what tip 1) Photovoltaic power station construction, should do a good job related consulting, and provide the professional knowledge of construction process and need what information? We should go to which department for examination and approval? What are the requirements for construction? 2) If the building photovoltaic power station in rural areas, in the case of roof ownership clear, also need to solicit the views of the surrounding neighbors, whether can bring inconvenience. For multi-story or high-rise residential roof, according to the property law and the Supreme People's Court on the trial of house ownership dispute 'the explanation of the concrete application of law, as the basic structure of the building roof, belongs to the structure of the common part, the owner shall have the right to share and common roof management. So, if people want to build distributed photovoltaic power station on the roof, they first need to understand whether the roof reserved the site of the installation of such equipment. In addition, they are also required to obtain the consent of the owner, the building that usually by the owners and the owners' committee decided through consultation.
