中文说明：在此方法中，控制器通过少量的阵列和措施的权力 ； 从调整电压如果功率增加时，直到不再增大功率，则会尝试这个方向作进一步的调整。这称为扰动和观察方法，是最常见的虽然这种方法可能导致输出功率振荡。 它被称为爬山方法，因为它取决于力量打击以下最大功率点和上面那点秋天的电压曲线上升。 扰动和观察是最常用的最大功率点跟踪方法由于其易于实现.
English Description：
In this method the controller adjusts the voltage by a small amount from the array and measures power; if the power increases, further adjustments in that direction are tried until power no longer increases. This is called the perturb and observe method and is most common, although this method can result in oscillations of power output.It is referred to as a hill climbing method, because it depends on the rise of the curve of power against voltage below the maximum power point, and the fall above that point.
