彩鋼屋面光伏發(fā)電項目屬于對已有建筑物彩鋼屋面的改造項目，因而建筑物的屋面形式、建筑物的結構形式、光伏陣列的布置形式及光伏組件本身的形式，以上條件的多樣性決定了屋面光伏支架的形式多種多樣。屋面的形式及建筑物的結構形式對光伏支架的工程造價影響較大。一般來說，屋面的防水等級越高，屋面防水層不外露，屋面的活荷載越大及建筑物整體結構較好、承載能力較強的屋面，光伏支架的工程造價越低，反之，工程造價越高。

Color steel roof photovoltaic power generation project belongs to the renovation project of the existing building color steel roof, so the roof form of the building, the building structure form, the layout form of photovoltaic array and the form of photovoltaic module itself, the diversity of the above conditions determines the various forms of roof photovoltaic bracket.The form of the roof and the structure of the building have a great impact on the engineering cost of the photovoltaic bracket.Generally speaking, the higher the waterproof level of the roof, the roof waterproof layer is not exposed, the greater the living load of the roof and the overall structure of the building, strong bearing capacity of the roof, the lower the project cost of photovoltaic support, on the contrary, the higher the project cost.

目前彩鋼屋面多為坡屋面，常見的坡度為5%和10%。屋面板為壓型鋼板或壓型夾芯板，下部為檁條，檁條搭設在門式鋼架等主要支撐結構上。在國內，此種類型的屋面安裝光伏電站實例較多。對于此種屋面，光伏組件可沿屋面坡度平行鋪設，也可以設計成一定傾角的方式布置。上部支架可通過不同的連接件、緊固件與屋面承重結構連接。

At present, the color steel roof is mostly slope roof, the common slope of 5% and 10%.The roof panel is pressed steel plate or pressed sandwich plate, the lower part is purlin, purlin is mounted on the main support structure.In China, there are many examples of this type of roof installation of photovoltaic power station.For this kind of roof, photovoltaic modules can be laid in parallel along the roof slope, or can be designed at a certain Angle.The upper bracket can be connected to the roof load-bearing structure through different connections and fasteners.

彩鋼瓦實際上是屬于彩鋼板的一種，只是彩鋼瓦主要是用于屋面的建材，一般都是單層的彩鋼板。而彩鋼板是一個非常大的類別，有單層和夾芯兩種，可用于屋面、墻面、隔墻板、吊頂和其他建材等，用途非常廣泛。

Color steel tile is actually a kind of color steel plate, but the color steel tile is mainly used for the building materials of the roof, it is generally a single layer of color steel plate.And color steel plate is a very large category, there are single layer and sandwich two kinds, can be used for roof, wall, partition board, ceiling and other building materials, the use is very wide.
