Description

Technical Field

[0002] Distributed photovoltaic power generation boasts proximity to users and short power supply distances, enabling it to deliver power to the main grid and meet its power supply needs. Furthermore, distributed photovoltaic power generation offers advantages such as a relatively sufficient energy supply, zero pollution, easy installation and subsequent management and maintenance, and a wide geographical distribution.

[0003] When air flows rapidly but is obstructed by photovoltaic modules, positive or negative wind pressure will be generated on the photovoltaic modules. These pressures are called wind loads. Wind has a great impact on the stability and normal use of photovoltaic modules. Since photovoltaic modules are usually installed in open and unobstructed areas, they are easily affected by wind and may be overturned or otherwise damaged. In order to prevent wind damage to photovoltaic modules, existing technologies install wind shields around the photovoltaic modules or fix them to the ground by adding tie rods. However, wind shields block the photovoltaic modules, and wind tie rods require the ground to be damaged for installation. They are also restricted to the ground and are not suitable for grounds of different materials. Based on the above situation, there is room for improvement. Utility Model Content
