One of the main obstacles to solar power production is the problem of partial shading and irradiance variation. The degree to which these factors can diminish the performance of a photovoltaic (PV) system depends on the specific shading pattern, PV array topology, and the physical location of the shaded PV modules within the array.

Partial shading condition drastically reduces the maximum power output of photovoltaic array. Partial shading occurs due to several factors, such as flying birds, trees, and passing clouds. Many ways can be mitigated partial shading problems in photovoltaic (PV) array.

Abstract Mismatch losses ignore the performance of individual photovoltaic (PV) modules and cut back most of the power from the PV array. These losses mainly due to partial shading condition (PSC), are caused by the reduction of spacing between PV modules, passing clouds, and near buildings, etc.

An Optimal Total Cross Tied Interconnection for Reducing Mismatch Losses in Photovoltaic Arrays
IEEE Transactions on Sustainable Energy, 2013A mismatch in a photovoltaic array implies differences in the I-V characteristics of the modules forming the array. This can lead to significant energy losses known as mismatch losses. The mismatch and the resulting losses can be reduced by altering the interconnection of the array. This paper proposes an optimal total cross tied interconnection, based

Abstract Partial shading of photovoltaic (PV) arrays results in hot spot creation and multiple peaks in the power-voltage (P-V) characteristics which ultimately leads to mismatch power loss in the PV system. This loss is a function of the shading pattern and configuration of the PV array.

Optimal total cross tied interconnection for photovoltaic arrays to reduce partial shading losses
2012 IEEE Power and Energy Society General Meeting, 2012The condition of having different irradiance levels among different photovoltaic modules in a photovoltaic array is called partial shading. Energy losses have been reported to occur due to partial shading. These losses could be reduced by reconnecting the modules of the array in such a way that the overall impact of partial shading on the array is ...

Abstract The goal of this paper is to investigate total-cross-tied (TCT) configuration under partial shading condition. A full investigation requires mathematical analysis and simulation. An accurate mathematical analysis gives us a better understanding of how partial shading affects the output curves of the solar cell, so we first mathematically ...
