Recently, Xiao Bian was informed that a 4KW photovoltaic power generation system at Gujia, a town in Xuanqiao Town, Pudong District, Shanghai, had successfully connected to the grid on August 29, and the current generation of electricity has reached 978 degrees. Mr. Gu introduced that his home used about 450 degrees per month of electricity, and now this photovoltaic system generates an average of more than 400 degrees per month. It uses self-use and surplus electricity to access the Internet and sells surplus electricity generated by the daytime system to the country. Manager Zhang of EPC Shanghai Energy Energia, who is in charge of this project, said that the photovoltaic system project of Mr. Gu's home is an ordinary villa installation and there are no technical problems in installation. However, there are some installation points need to pay attention to: 1, the bracket based on the way and installation. The foundation of the bracket is fixed on the concrete roof of the villa. If it is fixed too deep, the waterproof layer may be damaged, and the fixing is too shallow. The wind resistance and force of the bracket will be a problem later; 2. The anti-radar treatment. Installed on the roof of the villa, it is easily disturbed by lightning. It must be protected by lightning protection. 3. Ensure the safety of construction personnel. In general villa projects, tiles are generally glazed tiles or ceramic tiles, which are relatively slippery. Construction workers must pay attention to safety issues during the initial training period. In addition, Mr. Zhang also reminded users that when installing photovoltaic power generation system must choose a professional construction team, if the construction is not professional enough, the stability of the system is not enough, will significantly increase the project's post-maintenance costs. It is reported that Mr. Gu's home installation of the photovoltaic system from the application to the grid and sharing the use of 9 days, the whole process is relatively smooth, the grid company, Mr. Gu's neighbors and the community where the property is more compatible. Manager Zhang said that Shanghai, as a pioneer in photovoltaic power generation in China, has reached the forefront of policy support and subsidies, suggesting that the grid connection process can be simplified. Recently, the State issued frequent regulations to encourage the development of distributed photovoltaics, but many EPC companies stated that there are still many problems in the application and grid connection process. Some industry insiders responded that during the development of the urban-rural fringe and the rural distributed photovoltaic market, many residents found that they wanted to install a photovoltaic system. However, because many residents had only land use permits and no real estate licenses, they could not successfully apply. Faced with a huge market, it was a pity that it was blocked outside the threshold of the first application. EPC enterprises have responded that it is faster and more convenient to connect the Pudong District in Shanghai, and the grid connection processes in Songjiang and Jiading are relatively complicated. It is hoped that the local government can implement the new policy as soon as possible and remove obstacles to distributed development.
