Enhancement of the extracted maximum power of PV array during partial shading using switched PV-based system

Abstract

This paper proposes a switched PV approach to enhance the extracted maximum power from PV array during partial shading condition. The proposed system is simple and cost effective. However, it may provide lower power enhancement compared to other existing solutions which makes it more suitable for domestic applications. For assessing the proposed switched PV-based system, a detailed numerical comparison between the extracted power from the proposed system and other existing technologies has been presented for the same operating condition. Simulation and experimental results show a possibility of enhancing the PV array extracted output power during partial shading with the proposed system.
