<p><P>PROBLEM TO BE SOLVED: To efficiently explore an optimum operation point where a maximum electric power of an array assembly is generated, and to effectively utilize energy of solar power generation. <P>SOLUTION: A power conditioner 12 varies a voltage of its array assembly 11 in a region different from other adjacent array assemblies 11, and explores the operation point where the output electric power of its array assembly 11 reaches a maximum power point, and a comparing means 22 computes output electric powers at operation points explored by power conditioners 12 of the plurality of adjacent array assemblies 11, and compares the output electric powers including the current output electric power. A voltage determination means 23 extracts a voltage corresponding to a maximum electric power among the output electric powers compared by the comparing means 22 and determines it as an operation point voltage, and a voltage control means 24 outputs the operation point voltage determined by the voltage determining means 23 as a voltage command to the power conditioner 12 of the respective adjacent array assemblies 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
