The lightshelf system, a daylighting device, has been applied to improve the visual environment by optimal light distributions and intense illumination levels of a interior. Also, The photovoltaic is one of the most important sustainable technologies appliable to architectures. This study aims to evaluate the performance of photovoltaic integrated lightshelf system. For the study, the 1/5 scaled office models were made and the field tests were experimented under clear sky conditions. The power ratio has been analyzed to evaluate the performance of photovoltaic integrated lightshelf system. As results, the power performance was high on photovoltaic lightshelf installation angle $0^{\circ}$. And the performance was reduced on 23(%) by installation angle $15^{\circ}$ and 63(%) by installation angle $30^{\circ}$.
