Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to an efficient and stable photovoltaic bracket system. Background Art

[0002] Solar photovoltaic brackets are special brackets designed for placing, installing, and fixing solar panels in solar photovoltaic power generation systems. With the development of photovoltaics, more and more photovoltaic power generation projects are built on concrete roofs. Traditional photovoltaic brackets are greatly affected by wind loads and have high requirements on the bearing capacity of the original structure. When calculating the strength of concrete roof photovoltaic brackets, when the wind pressure is relatively large, the back wind is very unfavorable to the bracket structure. Therefore, the solution currently adopted in the industry is to add a windshield structure, such as a photovoltaic bracket system with a windshield disclosed in Chinese patent CN204376809U, in which a number of metal windshields are set in each interval between the solar photovoltaic panel and the building foundation. However, the windshield solution currently used is relatively simple, with only the function of wind shielding, and no other functions such as wind guiding. How to further increase efficiency at a low cost is also a research direction in this field. Summary of the invention
