Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a photovoltaic bracket structure for roofs. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a 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 modes of operation: independent operation and grid-connected operation. Photovoltaic is divided into two categories: one is centralized, such as large-scale northwest ground photovoltaic power generation systems; the other is distributed, such as residential rooftop photovoltaic power generation systems.

[0003] At present, when photovoltaic brackets are installed on roofs, holes are usually drilled in the roof and then fixed with expansion screws. However, this installation method will damage the roof, there is a hidden danger of leakage, and it is difficult to move the photovoltaic bracket after installation, which reduces the flexibility of the installation process. Therefore, we propose a photovoltaic bracket structure for roofs to solve the above problems. Utility Model Content
