The invention discloses a photovoltaic power generator capable of obtaining electric power from a solar cell at the maximum efficiency all the time, even under an uneven sunshine condition. The photovoltaic power generator 10 includes: a plurality of solar cell bodies SC1, SC2, ... formed by connecting the solar cells in series or in series-parallel connection; and a plurality of charge transfer circuits T1, T2, ... which are set for each solar cell body one by one and whose input terminals are connected with the anode and cathode of each solar cell body and output terminals are connected with a loading side in parallel. Each charge transfer circuit comprises: a plurality of capacitors C2-C8 which cumulate the output of the solar cell bodies in a form of charges; a plurality of semiconductor switching member SW1a~, SW2a~, SW3a~, SW4a~, SW5a~, SW6, SW7; a tracking control member M1 for a maximal power of the solar cell bodies; and an output controlling member M2 for transferring the charges cumulated in the capacitors to the loading side, so as to enable the output voltage Vox to be tracked approximately equal to a terminal voltage Vo of the loading side.
