Monocrystalline photovoltaic material based symmetrical and unsymmetrical Triple-Series Parallel-Ladder configuration for harvesting maximum power under partial shading conditions

Abstract

In recent years, renewable energy has made significant strides in energy markets, with solar energy emerging as a key player, as evidenced by the proliferation of photovoltaic (PV) array installations. However, challenges arise when these arrays operate under partial shading conditions (PSC), leading to disparities in array irradiance and decreased power output. Addressing this issue requires careful selection of PV materials and configurations. This study introduces a new Triple-Series Parallel-Ladder Configuration (T-SP-L) utilizing monocrystalline material PV to optimize output power under PSC. To assess its efficacy, symmetrical and unsymmetrical PV arrays is analyzed and compared with alternative configurations such as Total-Cross-Tied (T-C-T), Bridge-Link (B-L), Honey-Comb (H-C), and Series-Parallel (S-P), across various shading scenarios including Long-Narrow (L-N), Long-Wide (L-W), Short-Narrow (S-N), Short-Wide (S-W), and Middle (M).
