Researchers have developed a quadrant swapping reconfiguration technique for a 4×4 solar photovoltaic (PV) array to improve performance under partial shading conditions. The method employs a dynamic switching matrix that has been designed to rearrange module connections in real time, thereby minimizing mismatch and power losses. Experimental tests were conducted under ten shading scenarios with irradiance levels ranging from 100 W/m² to 1,000 W/m². The technique achieved a maximum output power of 136 W, zero mismatch loss and power loss in three scenarios, and a fill factor improvement of up to 0.57. Compared with traditional configurations such as series-parallel, total-cross-tie, and honeycomb, the system enhanced power output by up to 30% and reduced current variations across rows. Techno-economic analysis indicated a six-year payback period compared to seven years for conventional systems, demonstrating improved efficiency and cost-effectiveness for large-scale photovoltaic applications.
