“…The model used by [25] neglects the effect of shunt resistance. Swaleh and Green [27] discussed the impact of R sh under partial shaded conditions. In order to obtain the realistic model which provides the practical maximum power point values, it is mandatory to include the effect of varying R sh with respect to environmental parameters particularly for crystalline type SPV modules.…”

The aim of this paper is to investigate the effects of partial shading on energy output of different Solar Photovoltaic Array (SPVA) configurations and to mitigate the losses faced in Solar Photovoltaic (SPV) systems by incorporating bypass diodes. Owing to the practical difficulty of conducting experiments on varied array sizes, a generalized MATLAB M-code has been developed for any required array size, configuration, shading patterns, and number of bypass diodes. The proposed model which also includes the insolation-dependent shunt resistance can provide sufficient degree of precision without increasing the computational effort. All the configurations have been analyzed and comparative study is made for different random shading patterns to determine the configuration less susceptible to power losses under partial shading. Inferences have been drawn by testing several shading scenarios.

Photovoltaic energy harvesting systems (PV systems) are subject to PV cell faults, which decrease the efficiency of PV systems and even shorten the PV system lifespan. Manual PV cell fault detection and elimination are expensive and nearly impossible for remote PV systems, e.g., PV systems on satellites. Therefore, online fault detection techniques and fault tolerance solutions are needed that can detect and tolerate PV cell faults without manual intervention. In this work, we present an online fault detection and tolerance technique for remote PV systems, which is capable of dynamically locating faulty PV cells and tolerating PV cell faults. More precisely, we present a modified PV panel structure and an efficient algorithm for our online fault detection and tolerance. Our fault detection and tolerance technique reduces output power degradation due to PV cell faults in a PV system by up to 81.31%.

“…Curve 3 is the V-I output characteristics of the PV module, which is directly derived from Curves 1 and 2 since the PV module is a series connection of the two PV groups. Note that we assume that each PV cell is integrated with a bypass diode to protect the PV cell from reverse bias operation under partial shading [15] when we derive Curve 3.…”

This chapter introduces a reconfigurable photovoltaic (PV) cell array for adaptive and fault-tolerant energy harvesting in view of component modeling, architectures, properties, and reconfigurable algorithms for partial shading and fault tolerance. On top of traditional PV cell array-based energy harvesting research, the dynamically reconfigurable PV cell array gives additional significant benefits in both efficiency and cost. This is a representative example of how electronics design automation contributes to various problems in other domains.
