PURPOSE: An efficiency improving apparatus of a photovoltaic power generating apparatus is provided to optimize a cooling water spray control by separately arranging a cooling water supply tube according to a photovoltaic power generating array. CONSTITUTION: Photovoltaic power generating array areas are divided according to inverters. A cooling water supply tube(5) is branched according to the photovoltaic power generating array areas. The cooling water supply tube includes a branch(51-54) to supply cooling water to a cooling water spraying device. A valve(21-24) is arranged in each branch and controls the cooling water spray of the cooling water spraying device.
