Abstract
The biggest challenge in the solar system is to extract the maximum output powerfrom photovoltaic (PV) panels under different solar radiation and temperatureconditions. This paper presents a comparative study between perturb and observe(P & O) and incremental conduction (INC) algorithms. These are the most popularalgorithms for tracking solar PV panels and extracting the maximum power point(MPP) under different climate conditions. The studied PV system and the MPPTtechniques have been investigated by simulation using MATLAB/Simulink. Thesimulation includes a boost converter, which increases the PV panel voltage bycontrolling the duty cycle. The obtained results show that the P & O performanceclose to MPP under constant test conditions (STC) is better than the variableconditions due to oscillation. In contrast, the performance of the INC algorithm isbetter than P & O in terms of speed to reach MPP, accuracy, and quality underchanges in radiation and temperature conditions
