“…It will be important to investigate the type of shadow (transmittance) and the relative surface area of the shadow (Reinoso et al, 2013). The influence of partial shading on PV modules has been studied by several authors (Wang and Hsu, 2011;Gluchy et al, 2014;Tian et al, 2013). Some have focused on the angle of optimal system configuration under partial shading (Topic et al, 2017).…”

“…Hsu [8] found again that in most cases TCT configuration has a superior performance over the other PV array configurations such as S, P and SP. Some other publications are based on a comprehensive review on PV array configuration under partial shading conditions such as [9 & 10].…”

“…The examined indicators has not been fully covered in previously published articles such as [6][7][8][9][10]. Additionally, this research does not only examine several partial shading conditions affecting PV systems but also the modelling and the analysis of several faulty PV conditions (In-active PV modules) affecting various PV array configurations.…”

The goal of this paper is to model, compare and analyze the performance of multiple photovoltaic (PV) array configurations under various partial shading and faulty PV conditions. For this purpose, a multiple PV array configurations including series (S), parallel (P), series-parallel (SP), total-cross-tied (TCT) and bridge-linked (BL) are carried out under several partial shading conditions such as, increase or decrease in the partial shading on a row of PV modules and increase or decrease in the partial shading on a column of PV modules. Additionally, in order to test the performance of each PV configuration under faulty PV conditions, from 1 to 6 Faulty PV modules have been disconnected in each PV array configuration. Several indicators such as short circuit current (I sc ), current at maximum power point (I mpp ), open circuit voltage (V oc ), voltage at maximum power point (V mpp ), series resistance (R s ), fill factor (FF) and thermal voltage (V te ) have been used to compare the obtained results from each partial shading and PV faulty condition applied to the PV system. MATLAB/Simulink software is used to perform the simulation and the analysis for each examined PV array configuration.

“…The shading which generally refers to the moving cloud has very much similarity in the smoke-haze phenomenon whereby it blocks the direct sunlight and reduces the visible horizon of PV modules. To overcome this situation, most studies proposed different artificial intelligence and mathematical algorithm embedded in the MPPT (maximum power point tracking) and inverter devices [11][12][13].…”

Abstract:Recently, thick haze and poisonous smoke have cloaked the surrounding air in Malaysia due to the uncontrollable and unethical burning of nearby country. This devastating episode of open burning started in the year 1997 in Indonesia which deeply affected most of the ASEAN (association of southeast asian nations) countries especially their neighbour Malaysia and Singapore. The PV (photovoltaic) technology as an alternative means of energy generation experiences such significant energy decrease based on this condition which is due to the shading of sunlight. The 6 h claims of good sunlight has become not more than 2 h and gets worst when the API (air pollution index) struck 200 levels which is at very unhealthy condition. This study embraces some findings from 1 kWp PV generator field data installed in Malaysia reflecting the daily energy decrease operated during this unhealthy weather condition. It is found that, such significant energy decrease with the value of 0.43 W power output per increment of one point API. This value shows such concrete proof of additional factors to be considered in PV modelling in line to support PV technology adaptation in the ASEAN region.
