Color steel plate is generally used in light steel structure buildings, such as standardized workshops, warehouses, etc., according to its specifications, it is generally divided into angular color steel plate, right Angle locking type color steel plate and trapezoidal color steel plate. The light steel structure uses very light color steel tiles as the roof, which is also very large span, suitable for large-scale laying of photovoltaic modules.

The colored steel shingles are made of a thin layer of metal-clad foam, which cannot be fixed to the photovoltaic module's support by traditional methods. Special "clamps" are required, the use of which will not damage the original structure, nor cause roof leakage or damage to the overall structure. According to different color steel tile type, can choose the corresponding clamps or support foundation.

For angular and vertical locking type color steel tile, can directly use clamps as the basis of solar array, doesn’t affect its integrity, so these two forms of workshop roof is very suitable for roof distributed photovoltaic power station, and trapezoidal color steel tile roof because of the installation of solar array bracket will destroy the integrity of color steel tile, so there is a potential water leakage, Waterproof measures should be taken after installation in this way.

The installation of photovoltaic modules on color steel tile are based on clamps, clamp is not heavy, therefore the requirements for roof bearing capacity are not high . Given the carrying capacity, if the PV modules are installed at the optimal Angle, multiple supports are necessary to increase the weight of the roof.

In terms of safety, according to the optimal tilt Angle of the solar module array, the solar module array can’t be parallel to the roof, and extra wind pressure will be generated when the wind is strong which resulting in safety risks. To sum up, solar modules can only be tiled on the color steel tile roof, so the number of photovoltaic modules installed on the color steel tile roof is related to the area and bearing capacity of the roof.
