What should be paid attention to in the caigang watts roof installation of photovoltaic power station?

At present, a lot of color steel roof for slope roof, common grade of 10% and 5%. For or pressed steel sheet roof plate sandwich board, lower for purline, purlin build-up in the frame of door type such as main support structure. At home, this type of roof installation of photovoltaic power station instance

at present, most of color steel roof for slope roof, common grade of 10% and 5%. For or pressed steel sheet roof plate sandwich board, lower for purline, installed in the frame of door type such as main support structure. In China, there are many installed on the example of photovoltaic power station in the roof. For this kind of roof, pv modules can be placed along the roof slope parallel, or arranged in a certain slope. Stents can through different fittings and fasteners, connected with the roof supporting structure. The main form of common color steel roof are: vertical side whipstitch type, Angle type, bayonet, drive screw type, etc. Caigang engineering photovoltaic roof belongs to the renovation of existing buildings caigang roof, therefore, building the structure of the roof of the building form, decorate a form of photovoltaic array and photovoltaic components themselves, in the form of the diversity of these conditions determine the photovoltaic roof support the diversity of forms. The roof forms and structure forms has a great influence on the engineering cost of pv stents. In general, the higher the roofing waterproof level, roofing waterproof layer, the less the leakage. The higher the roof live load, construction overall structure, the better, the stronger the carrying capacity of roof, the lower the engineering cost of pv stents, on the other hand, the construction cost is higher. Caigang watts roof power stations have several important matters needing attention in design: first, clear the form of photovoltaic modules and laid method, clear the original form of the roof of the building. Second, the original building is clear structure and the main structure of the mechanical parts of business accounting. Three, according to the original building roof form, structure, form, photovoltaic array layout form, photovoltaic components themselves form, structure calculation results and the possible measures of construction conditions, gives all kinds of feasible support layout plan, determine the optimal layout. Four, rooftop photovoltaic engineering has its particularity in the construction, comprehensive consideration of site construction conditions, select the appropriate construction technology, and presents the matters of attention in the construction, construction protective safety measures, etc. The problems encountered in the construction and improvement Suggestions and measures; First of all, the scheme of optimal supporting scheme and tilt solution to water, dust, and the influence of high temperature. In the distributed power station construction, color steel roof tile slope can be used for evaluation. Caigang watts basically related to the industry. Caigang watts in summer temperature is very high. The high temperature will have some effect on the power generation efficiency. Second, photovoltaic component level arrangement, in order to reduce the shadow area and increase effective use area, so as to improve the efficiency of power generation. Third, in the summer, caigang watts after exposure temperature is very high, and the factory itself of the indoor temperature is relatively high, it has a great influence on the efficiency of the parts. Caigang watts on increasing spraying device is not only beneficial to plant cooling, but also to the tile surface cooling. Four, design reasonable group, reduce the length of the cable and the line loss. Five, the series inverter, improve the utilization rate of low illumination inverter low voltage start, improve hour comprehensive utilization.
