Under rapidly changing environmental conditions conventional MPPT techniques are required to operate fast, a large power loss can be caused by slow tracking speed, output power fluctuation, or additionally required ad hoc parameters. To achieve a fast and efficient MPPT technique that minimizes the power loss with the adaptively binary-weighted step (ABWS) followed by the monotonically decreased step (MDS) without causing output power fluctuation or requiring additional ad hoc parameter is the objective of this work. The simulation results are presented, shows that the ABWS and MDS MPPT technique is superior to the conventional perturb and observe (P&O) technique, which takes the 76.95% tracking time that of required by P&O technique and the overall power loss is also reduced.
