Abstract: There has been an increased attention to the photovoltaic(PV) systems during the last decade
owing to the many advantages. As a result, PV systems are being applicated in various places
including lakes, seas, exterior walls of buildings, and roofs as well as land. Above all, Building
Integrated Photovoltaic Systems replacing building finishing material with photovoltaic module has
been increasing. Building integrated photovoltaic systems are installed in a building by inserting a
solar cell in the building finishing material, therefore electrical safety must be ensured. Electrical
hazards in the BIPV systems can be defined as fire, electric shock or facility accidents. This paper deals
with the risk of electric shock in the BIPV systems. BIPV systems also have possibility of an electric
shock accident due to decreased insulation performance than conventional photovoltaic system
because it is easy to contact human body from electric leakage conductor. Especially, in case of a
system using non‐isolated inverter system, it is structurally vulnerable to safety, so that the risk of
accidents may increase. In this paper, as a study for improving electrical safety in BIPV systems, we
considered the hazard of electrical safety in the BIPV systems applied non‐isolated inverter and
conducted analysis risk of electric shock through verification experiment.
