Solar mounting system

  With the rapid development of distributed photovoltaic in China, the roof has become one of the most important carriers to install photovoltaic power station. Among them, the metal sheet roof is a common pitched type with a slope of 10% or 5%, which is made o f corrugated steel sheet or trapezoidal metal sheet, etc. Precautions in the design of  metal roof mounting system 1.Define the form and laying method of PV modules, as well as the roof type of the original building. 2.Make clear the structure form of the original building and check the main structure and stress member. The metal sheet roof is required to bear 0.15kn/m2 under the condition. 3.Generally, the metal sheet needs to be replaced every 10-15 years. Therefore, the metal sheet that has been used for more than its service life needs to be replaced. 4.If the owner has high waterproof requirements for the roof, or the roof is dilapidated, it is necessary to do waterproof and anti-corrosion treatment on the roof bef...
