An Optimal Triple-Series Parallel-Ladder Topology for Maximum Power Harvesting Under Partial Shading Conditions

the past few years, renewable energy has significantly contributed to the field of energy markets. Many photovoltaic (PV) array installations demonstrate the growing importance of solar energy. However, when operating under partial shading conditions (PSC), photovoltaic plants exhibit variable irradiance, which leads to low output power. Selection of the proper PV material and configuration are essential in overcoming this issue. This paper proposes a novel Triple-Series Parallel-Ladder Topology (T-SP-L) with monocrystalline PV material to maximize the output power under PSC. To comment on the effectiveness of the proposed topology, a 6x6 size PV array has been considered and compared with other topologies such as Series-Parallel (S-P), Honey-Comb (H-C), Total-Cross-Tied (T-C-T), Bridge-Link (B-L) considering Long Narrow (LN), Short Narrow (SN), Short Wide (SW), Long Wide (LW) and Middle (M) shading situations.
