Performance investigation of ShapeDoKu variant for PV formations under realistic assumptions of shading situations Optik (IF 3.1) Pub Date : 2024-03-07 Anurag Singh Yadav, Ajay Kumar Maurya, V. Mukherjee
During shading conditions, performance of physical relocation techniques for PV formations is more effective than total cross-tied (TCT) type of PV formation. The main purpose of physical relocation technique is to rearrange the physical position of PV modules in TCT formation without changing the electrical connections. Due to relocation of PV modules, the lengths of required wires are increased.
