The output power of a PV array is dependent on environmental factors such as solar irradiation and
temperature. So, it has a non-linear I-V characteristic. Maximum Power Point (MPP) is a point on the I-V, P-V
characteristic curve of a PV array where the PV device generates maximum output power. The location of MPP shifts
as the climate changes. MPPT's aim is to keep the solar operating voltage as similar to MPP as possible under changing
environmental conditions. They must run at their MPPT considering the inhomogeneous shift in environmental
conditions in order to continuously gather the full power from the PV array. Here the most commonly used MPPT
algorithms for PV applications are illustrated because they are easy to implement which are Perturb and Observe
(P&O), Hill Climbing (HC) and Incremental Conductance (INC). In this paper, the applications of those three MPPT
algorithms in PV systems at linear and nonlinear loads have been investigated. Comparative analysis
