Modern solar panel adjustable mounting brackets integrate sophisticated tilt mechanisms that support angle adjustments ranging from flat installations to steep inclinations, accommodating diverse roof types and ground-mounted configurations. Therefore, flexible PV mounting systems have been developed. These flexible PV supports, characterized by their heightened sensitivity to wind loading, necessitate a thorough analysis. The invention discloses a self-adaptive adjustment device of a photovoltaic support system. The self-adaptive adjustment device comprises a support base and an adjustment mechanism; the adjustment mechanism comprises two first adjusting plates, two second adjusting plates and a rotating shaft; the. Solar panel adjustable mounting brackets represent a revolutionary advancement in renewable energy installation technology, designed to maximize energy capture efficiency while providing unparalleled installation flexibility. The main aim is to design the support structure, transmission mechanism and tilting of the panel automatically on the daily basis depending on the wind pressure, so analysis and manual adjustment in the. Most existing aeroelastic wind tunnel tests on flexible photovoltaic (PV) support structures focus on single support forms, lacking comparisons of wind-induced vibration responses between different support types and multi-zone/multi-point refined analyses. This study employs a vision-based.
