A Total-Cross-Tied-Based Dynamic Photovoltaic Array Reconfiguration for Water Pumping System [PDF]

IEEE Access, 2022
Most Photo-voltaic (PV) applications require a shadow-free area for the installation of the PV panels. However, shading is inevitable in a few applications like building-integrated PV pumping systems (BIPVPS).

Maximizing Power Output of a Partially Shaded Total-Cross-Tied Photovoltaic array

Transactions on Environment and Electrical Engineering, 2017
Non-uniform conditions on the modules of the PV array, especially, partial shading reduces the output of the PV array to a large extent. The shaded module in a string limits the current of the entire string and hence, the output power of the string.  The
