A random process that has no memory – its result does not depend on earlier steps in the process. This means the next value of the process depends on the current value. It is independent of the previous values of the process. In probability theory, this property is also called the Markoff property.

That point on an I-V curve that represents the largest area rectangle that can be drawn under the curve. Operating a PV array at that voltage will produce maximum power.

MPPT - operating the array at the peak power point of the array's I-V curve where maximum power is obtained.
