Abstract :
This paper proposes a switched photovoltaic (PV) approach to enhance the extracted maximum power from a PV array during partial shading conditions. 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 conditions. Simulation and experimental results show the possibility of enhancing the PV arrays extracted output power during partial shading with the proposed system.
