<P>PROBLEM TO BE SOLVED: To provide a solar tracking method capable of tracking a solar position always, without attaching an optical sensor, calculating a formula of a solar orbit, nor periodic calibration of mechanical structure. <P>SOLUTION: The solar tracking method includes: a step (A), in the case where the attitude of a solar battery device changes, a short current is measured and recorded by using a short current measurement device, in synchronous at always with switching of a power element in a maximum power tracking control device, the short current is directly measured and recorded with the short current measurement device or an output power is measured and recorded by using a power measurement device of the maximum power tracking control device; a step (B) for calculating the maximum value of the short current or output power that has been recorded; and a step (C) for adjusting the solar battery device to an attitude corresponding to the maximum value of the short current or the output power by driving with a motor drive device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
