Rural what are the requirements for the installation of a photovoltaic power generation system in the residence?

Now rural users for photovoltaic power generation, the process has been basically unified, not like the past rafferty, the user as long as the owner id and photocopy of booklet of registered residence, house property card, Building property right certificate) A copy of the apply to the local power supply department

at present, rural users have basic unified application of photovoltaic power generation process, not chaos, just like she used to be. Users only need to provide a copy of the owner id card and residence booklet, as well as a copy of the certificate of property title ( Certificate of property title) Apply to the local power supply department. The local power supply departments to apply for the project, and debug and hooked up to the acceptance of the work. At the same time, the power supply department will complete the installation of the two-way meters, power purchase contracts and scheduling agreement, then the project can be combined. However, with an increasing number of distributed power generation project, some details has aroused people's attention. Because most of photovoltaic system built on the roof of the farmers, rural housing quality level is uneven. Some pv systems installed in foreign small layers of construction, other installation in the tile roof for peace. The next question is: if the roof disrepair, or its bearing capacity can not meet the standard, parts and support the additional weight of the roof can bear? It will be crushed? Such power stations for how long? This leads to the topic of building load, load is generally understood as a house can bear the weight of divided into permanent load and variable load. When the photovoltaic power generation system is built on the roof, the total weight of photovoltaic system will become a permanent load, this will require 25 years or longer. Photovoltaic system load is not 1 kg, but hundreds of kilograms. In the roof installation of photovoltaic power generation system, rural residents than urban residents to participate in more. Roof is your own, on the roof of your building photovoltaic systems don't need other owners or urban management department's permission. However, there are still a prerequisite. If the premise condition is not satisfied, even if had more money, it will not be built. This is the house carrying capacity '. In the past few years, rapid progress in rural. People's living standards greatly improved, living facilities also improved a lot. In many parts of rural areas in the pursuit of fashion, also appeared a lot of new things. Photovoltaic power generation is one of them. Roof bearing capacity of the new regulations in order to guarantee the quality of the house, given the stable operation of the plant. In some areas has issued a new rule, namely 'all application of photovoltaic power generation the user needs to provide housing proof load. Only a certificate issued by the relevant units after the acceptance of power supply department, square grid. If no such certificate, power supply bureau will not allow acceptance and Internet. The rules had been intended to standardize market behavior, to protect the interests of the people. Installed in a rundown on the roof of photovoltaic power plants. This is clearly some unscrupulous businessmen or salesman regardless of the actual situation of the customer 'bluffing' results. The roof itself looks likely to collapse at any time. Photovoltaic power generation systems on how to ensure its continued revenue in 25 years? However, in the process of implementation, will be a little difficult for rural users. As we know, many rural users build their own houses, some even no construction drawing, especially the detailed proof load.
