MPPT algorithms are independent of motion of the PV panel. They are only constrained by external parameters such as irradiation, temperature, load resistance, measurement variability etc.
Therefore, in the moving PV panel case as stated by Jerry Decker, you would need to consider a variable angle of incidence. If you are monitoring MPPT over an extended period of time, for example a day, you would also need to consider the azimuth angle.
If the panel is being used to power drive some source, you would also need to include changes in resistance. Moreover, if your terrain is rugged or wind speed is high, a lot of disturbance will be generated for measurement of inputs to the MPPT algorithm. This is in direct contrast to stationary panels which wont experience the same amount of disturbance.
