A matlab-based modelling to study and enhance the performance of photovoltaic panel configurations during partial shading conditions

Frontiers in Energy Research, 2023
Introduction: The utilization of solar energy in large-scale photovoltaic arrays has gained immense popularity on a global scale. However, shadows in the array lead to significant reductions in power output and create multiple power peaks in the P-V ...

Modeling and performance analysis of novel quad‐tied PV array configuration under partial shading conditions

Energy Science & Engineering, 2023
A photovoltaic (PV) cell is the smallest unit in an array that exhibits nonlinear characteristic curves. To gather the maximum amount of energy from a PV array under partial shading conditions (PSCs), it is necessary to follow the largest peak in the ...

Generalized coprime array configurations [PDF]

2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014
A coprime array consists of two uniform linear subarrays that construct an effective difference co-array with certain desirable characteristics. In this paper, we propose a generalized coprime array concept through the compression of the interelement spacing of one constituting subarray.

Power Enhancement in Partial Shaded Photovoltaic System Using Spiral Pattern Array Configuration Scheme

IEEE Access, 2021
Partial shading causes mismatch losses in the solar PV system. In the PV array, the power output from the healthy PV modules is gone in vain due to the mismatch losses.

A Novel Benzene Structured Array Configuration for Harnessing Maximum Power From PV Array Under Partial Shading Condition With Reduced Number of Cross Ties

IEEE Access, 2022
Partial shading (PS) phenomena significantly degrade the power output from the photovoltaic (PV) array. Due to the PS effect, there is a mismatch in current between the PV modules of a series-connected PV string.

Performance Enhancement of Partial Shaded Photovoltaic System With the Novel Screw Pattern Array Configuration Scheme

IEEE Access, 2022
The performance of the solar photovoltaic system is affected by the unpredictable phenomenon of partial shading. This causes the mismatch losses that suppress the power generation of healthy PV modules in it.

Enhancing Gain Through Optimal Antenna Element Distribution in a Thinned Array Configuration

IEEE Open Journal of Antennas and Propagation, 2023
This paper presents an array thinning approach for a 25-element antenna array arranged in a $5\times5$ grid at 5.4 GHz. Our goal is to eliminate a maximum number of antenna elements with minor gain loss and hence reduce the array size, weight, cost ...

Performance Evaluation of Static PV Array Configurations for Mitigating Mismatch Losses

IEEE Access, 2023
Solar photovoltaic (PV) systems are susceptible to power loss caused by environmental factors such as partial shading and temperature changes. To address this issue, PV modules are connected in array configurations. However, these configurations can lead
