NOVELTY - The photovoltaic power generation panel fixing component (23) has a fixing surface unit extended in upper direction. The fixing surface unit carries out fastening to a mounting surface unit (22) and has a facing surface unit (41) facing the side surface of a photovoltaic power generation panel. An engagement surface (42) is latched to an inclined securing protrusion (32), which is formed along the side surface longitudinal direction of the photovoltaic power generation panel in the facing surface part. A sharp nail unit (43) is provided in a protruding tip unit.    USE - Photovoltaic power generation panel fixing component for prefabricated building (Claimed), particularly carport.    ADVANTAGE - The photovoltaic power generation panel fixing component has a fixing surface unit that has a facing surface unit facing the side surface of a photovoltaic power generation panel and carries out fastening to a mounting surface unit, and thus ensures reliable electrical conductivity between a photovoltaic power generation panel and photovoltaic power generation panel fixing components. The photovoltaic power generation panel is grounded by conduction between the photovoltaic power generation panel and the photovoltaic power generation panel fixing component without using an earth wire, thus provides improved assembly operation in cost effective manner with reduced number of components.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a prefabricated building for forming a mounting surface unit on a roof body and mounting a photovoltaic power generation panel in the mounting surface unit.
