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 press-type sandwich panel, and the lower part is a purlin, and the purlin is erected on a main supporting structure such as a portal frame. In China, there are many examples of this type of roof-mounted PV power plants. 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. Caigang Roof Photovoltaic Power Generation Project is a project built on the Caigang roof of an existing building and belongs to the reconstruction project of the Caigang steel roof of the existing building. Therefore, the form of the roof of the building, the structural form of the building, and the layout of the photovoltaic array And in the form of photovoltaic modules themselves, the diversity of the above conditions determines the variety of forms of roof photovoltaic supports. The form of the roof and the structure of the building have a great influence on the construction cost of the photovoltaic support. In general, the higher the waterproof level of the roof, the waterproof layer of the roof will not be exposed. The larger 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. There are several important considerations in the design plan of the Caigang tile roof power station: First, define the form and laying method of PV modules, and make clear the roof form of existing buildings. Second, the structure of the original building is clearly understood and the main structural components are accounted for. Third, according to the original building's roof form, structural form, layout of the photovoltaic array, the form of the photovoltaic module itself, the structure of the accounting results and possible construction measures and other conditions, given a variety of feasible stent placement program, determine The optimal arrangement. 4. The roof photovoltaic project has its special construction features, comprehensively considers the on-site construction conditions, selects suitable construction techniques, and gives attention to the construction and safety construction construction protection agent measures. Nine factors affecting photovoltaic power generation on the color tile roof: First, the amount of solar radiation; Second, the installation angle of the battery assembly; Third, the effectiveness of battery components; Fourth, the combination of the entire component loss; Fifth, the temperature characteristics of the battery module; Sixth, maximum output power tracking (MPPT); VII. Loss of lines; VIII. Loss of power generated by dust cover; Nine, inverter, controller efficiency has a certain influence on power generation capacity of the power station. Problems encountered during construction and suggestions for improvement and measures: First, adopt the best support scheme and inclination scheme 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. The color steel tile is basically related to industry. The color steel tile has high temperature in the summer, and the high temperature has some influence on the power generation efficiency. We have done a relevant best dip test in the Yellowstone area. The inclination was done with three supports, 0° to 90° related tests and experiments. What we can now see is the data of the inclination data of the power station panel in July 2015. The 15° angle of inclination should be the time when the power output is the highest. The following table is the experimental data for 2014 and 2015 that we have summarized. From the analysis results, the best dip angle in Huangshi area is 25 degrees south. 2. Photovoltaic modules are arranged horizontally to reduce the shadow area and increase the effective use of the area, thereby increasing 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. Fifth, the use of string inverters to improve the utilization of weak light, inverter low voltage start, improve the comprehensive utilization of hours.
