<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for diagnosing a solar photovoltaic system in which the state of defects such as decline in the power of a solar cell array or a solar cell module is diagnosed to easily investigate the reason for the defects. <P>SOLUTION: The apparatus for diagnosing the solar photovoltaic system includes: a voltage sensor 6; an electric current sensor 7; a reference voltage setting section where reference voltage is variably set; a reference electric current setting section where reference electric current is variably set; a gate circuit 8; a voltage controller 10; and an electric current controller 11. Any of the following is output from a voltage output section 12 and electric current output section 13, respectively, by switching a control signal switching section 9: the reference voltage set in the reference voltage setting section, and the electric current detected in the electric current sensor 7 corresponding to the reference voltage; and the reference electric current set in the reference electric current setting section, and the voltage detected by the voltage sensor 6 corresponding to the reference electric current. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
