Abstract

The structure of the photovoltaic system is important because it's rigidity is required enough to withstand extreme environments such as typhoons. In addition, the driving mechanism of the structure affects the power generation efficiency. Among the mechanism of a photovoltaic structure, the efficiency of the solar tracker using rotating two axes is best. In this paper, a new solar tracker using dual worm-gear was designed and fabricated. The designed solar tracker was evaluated through FEM to confirm the rigidity to withstand extreme wind loads obtaining strains and the stresses of tracker at two different blower locations. For the fabricated structure the wind tests were conducted at seven different blower locations. To measure the strain during the wind test, the strain gages were used.
