ON THE CAPACITY OF SOLAR CELLS UNDER PARTIAL SHADING CONDITIONS

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2021
A photovoltaic system under uniform illumination conditions has only one global maximum power point, but this same panel in the case of partial shading conditions can have more maxima on the power-voltage curve.

Partial Shading Condition on PV Array: Causes, Effects and Shading Mitigation using DSMPPT

International Journal of Engineering and Advanced Technology, 2020
Solar photovoltaic (PV) systems are gaining importance increasingly as it directly converts solar radiation into electrical energy which is renewable and environment friendly. Where it has a numerous advantage, some disadvantages are also there like its dependency on environmental conditions.

A Hermite interpolatory subdivision scheme for $C^2$-quintics on the Powell-Sabin 12-split [PDF]

, 2014
In order to construct a $C^1$-quadratic spline over an arbitrary triangulation, one can split each triangle into 12 subtriangles, resulting in a finer triangulation known as the Powell-Sabin 12-split.

Power enhancement in PV arrays under partial shaded conditions with different array configuration

Heliyon
Solar Photovoltaic systems are used for electrical power generation, and they provide an alternative source to non-renewable energy sources like coal, oil, natural gas and nuclear energy. Photovoltaic arrays used in PV systems may be subjected to partial

Improved PV Module Performance under Partial Shading Conditions

Energy Procedia, 2013
AbstractIn a typical series-connected photovoltaic module with three bypass diodes, not all of the energy generated by the individual cells in the module can be collected when one or more of the cells in the module are partially shaded. In this work, various photovoltaic (PV) module layouts are investigated, using both full-size solar cells and halved ...

Numerical modeling, simulation and evaluation of conventional and hybrid photovoltaic modules interconnection configurations under partial shading conditions

EPJ Photovoltaics, 2022
Partial shading on solar photovoltaic (PV) arrays is a prevalent problem in photovoltaic systems that impair the performance of PV modules and is responsible for reduced power output as compared to that in standard irradiance conditions thereby resulting

PV array reconfiguration method under partial shading conditions

International Journal of Electrical Power & Energy Systems, 2014
Abstract This paper proposes a new reconfiguration method for photovoltaic arrays under partial shading conditions. With the application the method, the array can produce higher power by reconfigured connections of array. In the proposed method, each row of an array is formed by connecting the panels with close short circuit current levels as ...
