Output Power Maximization of Partially Shaded 4*4 PV Field by Altering its Topology

The mismatch losses in PV modules are mainly because of the partial shading and can be reduced by altering the topology of the modules within the array. The modules can be interconnected in many ways like Series Parallel (SP), Bridge Linked (BL) and Total Cross Tied (TCT) connection in an array to increase the output power. In this paper the best topology is suggested for a particular pattern of easy-to-predict shade on PV fields.
