Description

Technical Field

[0001] The utility model relates to the field of photovoltaic buildings, and in particular to a BIPV structure. Background Art

[0002] Building integrated photovoltaics (BIPV) is a technology that integrates solar power generation (photovoltaic) products into buildings. Existing photovoltaic arrays set up in locations such as building roofs generally use sealants to seal the joints of photovoltaic panels, so that multiple photovoltaic panels are sealed and spliced ​​into a photovoltaic array with an overall planar structure to achieve waterproofing of the photovoltaic array surface. However, dust is easily accumulated on such photovoltaic arrays. When robots are used for waterless cleaning or other cleaning methods, the swept dust can only move on the surface of the photovoltaic panels and cannot fall. The problem of dust destination cannot be solved, which will lead to reduced power generation efficiency or even damage to the photovoltaic panels.

[0003] The prior art patent application number 2022202503819 discloses a BIPV structure, including a photovoltaic panel and a longitudinal water guide groove structure, wherein a longitudinal water guide groove is provided between two laterally adjacent photovoltaic panels, and the longitudinal water guide groove structure is suitable for being arranged in or below the longitudinal water guide groove; and the longitudinal water guide groove structure is provided with a longitudinal water guide groove opening upward. However, during actual installation, the photovoltaic panel lacks corresponding support and is prone to directly exert corresponding pressure on the longitudinal water guide groove structure, resulting in damage to the longitudinal water guide groove structure and leakage.
