Due to the unique structure and material, the hollow sunlight plate can be arched like some other materials. However, the bending direction of the hollow sunlight plate must be parallel to the direction of the skeleton, that is, it bends along the direction of the rib, otherwise it is easy to damage the plate. When installing PC hollow solar panel arches, the span of the solar panel should be determined according to different curvature radii, and the length of the panel should be greater than or equal to the width of the panel. At the same time, in order to prevent the influence of ultraviolet ray on the board, the protective film with UV layer has a printed sign, which must be installed facing the sun.
The correct selection of the thickness of the hollow sunlight plate is also very important for the later use effect. At the same time, it is also important to consider that the plane construction should be designed with a gradient of 11% to facilitate water removal. When installing the hollow solar panel, the expansion space shall be reserved according to the local temperature difference, and the embedded depth shall be noted; If the plate is fixed with screws, the opening diameter shall be 1.5 times of the screw diameter. Sometimes it is also necessary to cut the hollow sunlight plate. Before this, it is necessary to mark lines and marks, which should be written on the protective film, and then use crayons to avoid damage to the plate surface when using sharp tools for marking. Before installation, lift the protective film about 5cm around to facilitate construction. When the surface of the hollow solar panel is polluted by the adhesion of caulking material, grease, paint, etc., it must be wiped off with a soft cloth dipped with absolute alcohol, kerosene or gasoline before hardening, but it should be noted that organic solvent, strong alkaline chemical solvent cannot be used for cleaning, and it is not allowed to walk directly on the panel surface.
In order to prevent internal stress, a certain expansion gap shall be reserved for PC sunlight plate; The plate edge shall also be extended into the fixed frame for more than 25 mm, and at least two ribs shall be installed into the fixed area. The protective film shall be removed immediately after the installation of the hollow solar panel, and then the secondary coating shall be done until the completion of the project.
