To judge the quality of distributed photovoltaic projects?

A, 1, project development company compliance ( 1) First of all need to get the land certificate, house property card housing land card and house property card. For house hasn't been dealt with house property card, have to get a construction project planning permit, otherwise, the house can be  as temporary buildings,

1 a, development company. Compliance of the project ( 1) Land certificate and house property card: first of all, you need to acquire building land card and house property card. For house not have house property card must obtain a construction project planning permit, otherwise, the house can be seen as temporary buildings, leading to the roof of the lease contract is invalid. For a land card and house property card project, it is important to check these two documents in the area is consistent with the actual construction area. For projects involving multiple roof, also need to check whether received each house property right card. To hold land certificates and construction project planning permit, must go to the real estate certificate issued by the local authorities, prove that it is operating. At the same time, we need to get the house fire inspection report, otherwise we might not be able to complete the grid check for normal and connected to the grid. ( 2) Right: the main roof under the lessor to verify whether the property right person for this building, such as the authorized without property right person; For projects involving multiple roof, it is necessary to sign a lease agreement with each of the building owner. , roof projects shall be obtained from proprietary parts of total building area of more than two-thirds, the consent of the owner more than two-thirds of the total. 2. Technical analysis ( 1) Roof load: need to get the engineering drawings of the building, and find the three of the original design units or buildings inspection institution to load. You need to see if consistent with the actual construction drawings. Constant load of 50 kilograms of reinforced concrete roof and constant load for more than 15 kg caigang watts roof can satisfy the requirement of photovoltaic installation, and can be fully paving. If can't meet all the pavement, can reduce or the installation of the reinforcement project size to meet the conditions. This proposal development company don't skip this step in order to save money. Many projects finished procedure until after load does not conform to the requirements, do more harm than good. ( 2) Roof: the roof type is usually divided into reinforced concrete roof and caigang watts roof. Photovoltaic power is concentrated in the cement roof needed to research on the roof of large equipment may be blocking a photovoltaic module. For caigang watts roof, in addition to the load, large equipment shielding and parapet shielding, daylighting and roof age (should also be considered Suggestions in five years to build) The impact on the corrosion and leakage. Do not recommend building trapezoidal caigang watts roof, this will lead to leakage. ( 3) Access: need to collect the main electrical wiring diagram and electrical room layout, combined with the local power grid policy ( Small 0. 4 kv transformer on access to no more than 25%, T connection line transmission capacity is not more than 30%, the specific proportion by the local power grid companies to verify) 。 Access should be determined by the number and capacity of the transformer ( Dedicated line public power grid access or through internal grid users access the public power grid) 。 Determine access, need to check the transformer room for reserve interval. Low voltage grid, to project the spontaneous for private use, recommended to reduce construction cost, easier to meet yield. About access, need more to mention is spontaneous self-used project is involved in 'through the partition sales power'. Under normal circumstances, several plants share a transformer and a meter. If the power grid company has only one account, so the roof of a few plants can be used at the same time, the power can be used for a family. This does not include within the scope of the 'through partition sales power'. Please consult the local power grid company for detailed requirements.
