There has been a huge exploration since the invention of PV cells to find new techniques to efficiently fit the PV array for a particular application. Each technique has its own way of effectively extracting power from the PV source. In any way, all the techniques strive for faster convergence to Maximum Power Point (MPP) under static and dynamic irradiation conditions. Simplicity, accuracy and rapidity are the main aims of developing new techniques. In this paper a method was devised in a simple manner to reach MPP faster with excellent accuracy. The method was contemplated by focusing only on the PV characteristics' power zone and applying an interval in the said region. An exponential scanning algorithm is proposed, which makes the interval shrink sequentially in a self-adaptive fashion at each iteration by applying search conditions and finally reaches the MPP. The interval selection is also explained, and its practical determination requires only the data contained in the PV module's datasheet. Computer simulations and experimental evaluation confirm the effectiveness of the presented technique. The convergence to the MPP is faster, and the efficiency obtained in simulations and experimental evaluation is more than 99%. © 2024 Elsevier B.V., All rights reserved.
