Reduction of mislead power and mismatch power loss under partial shading conditions using novel square matrix shade dispersion technique

Solar Energy, 2020
Abstract Generated output power from SPV array decreases drastically during Partial Shading (PS) conditions. Due to PS, multiple peaks arises in P-V and I-V characteristics of SPV array, instead of single Global Maximum Power Point (GMPP) peak. Such multiple peaks make it difficult to track GMPP.

Advances in Mismatch Identification and Power Loss Evaluation of Concentrating Photovoltaic Multijunction Module

AIP Conference Proceedings, 2011
The outdoor I‐V curve of a concentrating photovoltaic (CPV) Multi‐junction (MJ) module is affected by temperature, series resistance, electro‐optical mismatches among receivers mainly due to soiling effects, tracker misalignment and a particular spectral solar content.

Power loss in photovoltaic arrays due to mismatch in cell characteristics

Solar Energy, 1979
Abstract Variations in the current-voltage characteristics of photovoltaic cells can lead to significant power loss “due to mismatch” when the cells are connected together in a network. This study explores how this mismatch loss depends on variations in max-power current and max-power voltage from cell to cell. An analysis of a series string is first

The influence of mismatch of solar cells on relative power loss of photovoltaic modules

Solar Energy, 2013
Abstract This paper presents a study of mismatch losses when solar cells are associated in series to form photovoltaic (PV) modules. In this experiment, more than 10,000 single-crystal and multi-crystal cells were measured and sorted according to cell maximum power (Pmpc) and short circuit current (Isc).

Mismatch Losses in Photovoltaic Power Generators Due to Partial Shading Caused by Moving Clouds

2012
In this paper, we have investigated the effect of partial shading due to moving clouds on mismatch losses of five different PV power generator configurations. These configurations are a string of six series-connected PV modules, two strings of three series-connected PV modules, which are either separately controlled or connected in parallel, and three ...

Reducing Mismatch Losses in Grid-Connected Residential BIPV Arrays Using Active Power Conversion Components

2010
Building-integrated photovoltaics (BIPV) have seen an impressive development throughout the world this last decade. In France, photovoltaic (PV) installations under 3 kWp represent 90% of the plants in service as of 2009, and count for 42% of the national installed photovoltaic power [1].

Influence of the Current Mismatch in Triple-Junction Solar Cells on Power Losses in S3R

IEEE Journal of Photovoltaics, 2014
This paper presents the results of an experimental investigation of the transient behavior of illuminated triple-junction solar cells (TJSCs). The experimental data have shown that the transient behavior of TJSCs during the transition between the open-circuit point and short-circuit point (SCP), and the maximum-power point and SCP has a complex shape ...

Impact of losses and mismatches on power and efficiency of Wireless Power Transfer Systems with controlled secondary-side rectifier

Integration, 2016
Abstract In this paper an effective model for the power and efficiency analysis of Wireless Power Transfer Systems (WPTSs) is proposed. Such enhanced model includes modulation of duty-cycle and phase-shift for the secondary side controlled rectifier, as well as power losses of semiconductor devices and parameters mismatches of resonant elements.

Power and mismatch losses mitigation by a fixed electrical reconfiguration technique for partially shaded photovoltaic arrays

Energy Conversion and Management, 2019
Abstract Partial shading is the most commonly occurring scenario among the modules of the photovoltaic arrays invoking power and mismatch losses. To attenuate these losses, various interconnection topologies for partial shading mitigation have been proposed in the literatures.

Potential-induced degradation: Recombination behavior, temperature coefficients and mismatch losses in crystalline silicon photovoltaic power plant

Solar Energy, 2019
Abstract In recent years, potential-induced degradation (PID) has gained considerable attention due to the significant negative impact on output power of photovoltaic power plant. In this paper, the recombination behavior of PID-affected solar modules dismounted from the photovoltaic power plant was investigated by the two-diode model of photovoltaic
