ABSTRACT
This paper is dealt with some issues of the finite element analysis (FEA) of ground-mounted photovoltaic (PV) structure, focusing on the entire structure where the panels under a wind load considering regional climatic data. The eigenvalue extraction used to calculate eigenfrequencies and mode shapes is based on the Lanczos iteration method. The frame and purlins were modeled as a 3D wire frame and meshed with the linear beam elements with specify C and U cross-section shapes. The PV panels were meshed with composite shell elements. The purpose of finite element analysis is to provide a starting point for studies of the forced vibrations with the results of modal analysis.
