Floating type photovoltaic power generation system

PURPOSE: A floating type photovoltaic power generating device is provided to reduce manufacturing costs by supporting a floating structure system using a synthetic resin pipe. CONSTITUTION: A floating structure(10) functions as a floater and a structure and includes a pipe filled with air. A combining unit(40) is combined with the floating structure and partitions the floating structure to a plurality of parts. A plurality of solar cells(30) are rotatably installed in the combining unit.
