“…The switching matrix differences with others switching matrix proposed. In [34] the authors proposed switching matrix which can sorts the system's strings into two categories: the main PV string (MPV), which forms complete strings with the proper number of modules, and the sub-PV string, which forms a partial string that consists of the remaining PV modules that do not meet the required number to form an MPV. In operation, shaded PV modules are connect to DC/DC inverter in string; other PV modules do not change position.…”

Under non-homogeneous solar irradiation, photovoltaic (PV) panels receive different solar irradiance, resulting in a decrease in efficiency of the PV generation system. There are a few technical options to fix this issue that goes under the name of mismatch. One of these is the reconfiguration of the PV generation system, namely changing the connections of the PV panels from the initial configuration to the optimal one. Such technique has been widely considered for small systems, due to the excessive number of required switches. In this paper, the authors propose a new method for increasing the efficiency of large PV systems under nonhomogeneous solar irradiation using Series-Parallel (SP) topology. In the first part of the paper, the authors propose a method containing two key points: a switching matrix to change the connection of PV panels based on SP topology; the demonstration that the SP-based reconfiguration method can increase the efficiency of the photovoltaic system up to 50%. In the second part, the authors propose the extension of the method proposed in the first part to improve the efficiency of large solar generation systems by means of a two-levels architecture to minimize the cost of fabrication of the switching matrix.

This article addresses the technical and economic challenges regarding the design of a "green" recharge area for electric vehicles at the University of Palermo in order to reduce costs and pollution connected to the charging process. Based on the behaviour of the student population, the electrical load is identified and two possible solutions are evaluated to manage the peak load: an orientation of the panels increasing the power at defined time and the use of a storage system. The main strength and weakness points of two systems are investigated by taking into account the Levelized Cost of Energy (LCOE), which reaches 75.3 €/MWh for the orientation of panel and 103 €/MWh for the storage system. Furthermore, the cost of the topologies of power plant and the cost of energy are discussed in depth.

“…Unfortunately, real-world PV power stations often operate at undesirable working conditions [4,5]. It is reported that the annual energy loss due to partial shading is about 10-20% [6] and the production loss (due to mismatch, faults or failures) results in significant economic losses [7][8][9]. A comprehensive solution for these problems is termed as the PV monitoring system that improves the system reliability with the minimal cost [10] and plunges the energy production levels from different available solar irradiations [4,5].…”
