<p><P>PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system always operable at a maximum electric power point of a solar panel without depending on a solar battery characteristic and a load characteristic of a pump. <P>SOLUTION: This photovoltaic power generation system has the solar panel 1, an inverter 2 for driving a load by converting output DC power of the solar panel 1 into AC power, and a control device 4 for controlling the inverter 2, and increases-decreases or maintains a frequency of the output AC power in the inverter 2 on the basis of a change in an electric power (P) - voltage (V) coordinate system of the DC power by measuring output DC power P and voltage V of the solar panel 1, and drives the load 3 at a variable speed so as to follow the maximum electric power point of the solar panel 1. <P>COPYRIGHT: (C)2003,JPO</p> |
