Caigang tile roof installation of photovoltaic power station

article source:unknown date:2018.01.24 share it
At present, most of the steel roofs are slope roofs, and the common slopes are 10% and 5%. The roof panel is a press-type steel plate or a press-type sandwich panel, and the lower portion is a purlin, and the purlin is erected on a main support structure such as a portal frame. In China, there are many examples of this kind of roof-mounted photovoltaic power station. For such roofing, photovoltaic modules can be laid parallel to the slope of the roof, or they can be arranged in a certain angle of inclination. The upper bracket can be connected to the roof load-bearing structure through different connectors and fasteners. The main forms of common color steel plate roofs are: standing seam type, angular type, bayonet type, and clear nail type. The Caigang tile roof roof photovoltaic power generation project belongs to the reconstruction project of the Caigang steel roof of the existing building, and thus the roof form of the building, the structural form of the building, the layout form of the photovoltaic array and the form of the photovoltaic module itself, the above conditions are various Nature determines the variety of forms of roof photovoltaic supports. The form of the Caigang roof and the structural form of the building have a great influence on the project cost of the PV bracket. In general, the higher the waterproof level of the roof, the waterproof layer of the roof will not be exposed. The higher the live load of the roof and the better the overall structure of the building and the stronger bearing capacity, the lower the construction cost of the photovoltaic bracket, and conversely, the construction cost. The higher. Several important matters needing attention in the design project of Caigang tile roof power station 1. Definite the form and laying method of PV modules, and clear the form of the roof of the original building. 2. Clearly understand the structure of the original building and calculate the main structural components. 3. According to the conditions of the roof structure, structure of the original building, the layout of the PV array, the form of the PV module itself, the structural accounting results and the possible construction measures, a variety of feasible bracket layout plans are given. The optimal arrangement. 4. The roof photovoltaic project has its particularity in construction, comprehensively considers the on-site construction conditions, selects the appropriate construction technology, and gives the precautions during construction and the construction safety protection agent safety construction measures. Problems encountered in the construction of the project and suggestions and measures for improvement. First, adopt the best support scheme and dip plan to solve the effects of accumulated water, dust, and high temperature. In the construction of a distributed power station, the roof color tile slope can be used for evaluation. Color steel tile is basically related to industry. Color steel tile has high temperature in summer, and high temperature has some impact on power generation efficiency. 2. Photovoltaic modules are arranged horizontally to reduce the shadow area and increase the effective use area, thereby increasing the power generation efficiency. Third, in summer, the temperature of the steel tile after exposure to the sun is very high. In addition, the indoor temperature of the industrial plant itself is relatively high, which has an impact on the power generation efficiency of the components. The addition of spraying devices on the color steel tile will not only help the cooling of the power station, but also help cool the tile surface. Fourth, design a reasonable set of string, reduce cable length and line loss.
