Recently, the manually adjustable solar structures are reguired for the angle variation of solar module to increase the electric power efficiency. Therefore, this study presents the adjustable connections in support structure and estimates the stiffness of the connections for the structural performance evaluation of the manually adjustable solar structure

Mostly, solar panel support structure has been constructed as flat-type structure. But, it is not harmonized with the existing buildings. Therefore, this study presents the curved support structures and performs the structural analysis for the selection of member size. Also, the structural safety is evaluated through joint experiments and finite element analysis.
