[0002] Photovoltaic: short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two operation modes: independent operation and grid-connected operation. At the same time, the solar photovoltaic power generation system can be classified into two types: one is centralized, such as large-scale northwest ground photovoltaic power generation systems; the other is distributed (with >6MW as the boundary), such as industrial and commercial enterprise factory roof photovoltaic power generation systems and residential roof photovoltaic power generation systems.

[0003] Currently, most solar photovoltaic panels are fixedly installed on the corresponding roofs through corresponding photovoltaic panel brackets. The existing roof photovoltaic panel brackets generally include guide rails.

The installation operation process is complex and the convenience is insufficient, resulting in low installation efficiency. In addition, the structural stability is insufficient, making it difficult to effectively ensure the installation stability of the photovoltaic panels. In view of this, the utility model provides a roof photovoltaic bracket. Summary of the Utility Model
