Mitigation of mismatch power loss in aged photovoltaic arrays following a comparative investigation into module rearrangement techniques

Electrical data of 10W, 40W, 80W, and 250W photovoltaic modules under the aging condition: Tested by a Solar Manufacturer Company in Bangladesh

“…4 shows the Maximum power point voltage (Vmp), current (Imp), and power (Pm) of the aged PV modules of 10W, 40W, 80W, and 250W ratings. Where a correlation between the Imp and Pm is already identified in the published research article [1] . However, the relation between the Vmp, Voc with the Pm, and mismatch power losses are not investigated yet.…”

“…Therefore, six array configurations, 2 × 20, 4 × 10, 5 × 8, 2 × 2, 10 × 4, and 8 × 5 can be used to investigate the relation between the array size and mismatch power losses. Moreover, using these datasets different module rearrangement techniques can be investigated by simulation considering power losses, array dimensions, array output power for aged PV arrays [1] .…”

“…Therefore the percentage of nonuniformity of an aged module in an array can be calculated from the deviation of its output power from the average value. These degraded modules are the key source of the mismatch power losses in the large PV arrays [1] .…”

“…3 illustrates the short circuit current (Isc) of the 10W, 40W, 80W, and 250W PV modules. The relationship between the module parameters (Voc and Isc) and mismatch power losses is not investigated in the related research paper [1] . Therefore, further research can be done using these datasets.…”

Electrical experimental data collection of polycrystalline and monocrystalline photovoltaic modules in an indoor environment using artificial sun simulator

“…The experimental dataset presented in this paper contains the electrical parameters of several PV modules and a prototype PV array that were examined in a laboratory setting using an artificial sun simulator [1] combined with microcontroller based I-V tracer and data-logger [2 , 3] . Fig.…”
