Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a waterproof installation structure for rooftop photovoltaics. Background Art

[0002] Rooftop photovoltaic power generation refers to the installation of a photovoltaic power generation system on the roof of a building, which converts solar energy into electrical energy through photovoltaic modules and supplies the building with it or transmits it to the power grid. The photovoltaic power generation system includes photovoltaic modules, inverters, distribution equipment and monitoring systems, among which the photovoltaic panels on the photovoltaic modules are fixed side by side on the roof through a mounting structure to receive sunlight.

[0003] Traditional rooftop photovoltaic modules are directly installed and fixed to the roof concrete layer through metal components. For example, application number 202122564956.2 discloses a mounting structure for a rooftop photovoltaic bracket, including purlins, photovoltaic module connectors arranged on the purlins, and a water tank. The first end of the photovoltaic module connector is connected to the purlin, and the second end is connected to the frame of the photovoltaic module and the edge of the water tank. The above-mentioned photovoltaic module connectors use fasteners such as bolts to tightly fix the photovoltaic module, the water tank and the purlin together, and the above-mentioned mounting structure is suitable for photovoltaic modules arranged flat. For photovoltaic modules arranged on an inclined surface, different structures are required to support the photovoltaic modules on an inclined surface. When photovoltaic modules arranged on an inclined surface are used on rainy days, rainwater will flow into the lower inclined surface of the photovoltaic module, causing rainwater to concentrate on the roof surface. It is easy to cause waterproof damage to the concrete roof surface over a long period of time. When fasteners such as bolts are inserted and fixed to the roof surface, it is easy to damage the roof waterproof layer, affecting the waterproof performance of the roof. Utility Model Content
