[0002] Photovoltaic green building materials are installed on the roof to form photovoltaic roofs, photovoltaic skylights, photovoltaic tile roofs, photovoltaic metal roofs, etc. Roof waterproofing has always been a difficult problem in the construction field. With the popularization of photovoltaic green energy, problems arise due to the long exposure of the roof to light and the fact that the efficiency of photovoltaic power generation is also closely related to the angle of the photovoltaic panels. Photovoltaic panels are added to the inclined surface of the skylight, and the waterproofing of the skylight is already difficult to handle. After the photovoltaic panels are added to the skylight, more connection nodes will be added. The more connection nodes, the more difficult it is to waterproof, which cannot meet actual needs.
