“…The author"s have already developed a theoretical model for estimating V-I plotting time, taking into consideration the effect of Effective Series Resistance (ESR) value of the supercapacitor also. Recent results [8] communicated by Pal et al indicates very close agreement between the experimental plotting time with the theoretical estimated value. Typical values of curve plotting time are shown in table 2 for 10 Watt poly-Si module.…”

Photovoltaic (PV) Energy Conversion is currently the most trusted potential avenue for generating electrical power. Currently, the price of conventional grid electricity is globally on the rise, where as the prices of PV modules (building Blocks for any PV system) are gradually on the decline. So there is every reason to trust that Solar Photo-voltaic systems (SPS) will emerge as a cheap and decentralized source of electricity in a big way in course of a decade. In the measurement procedure followed by the authors, Supercapacitor(s) are used as load to the PV module under test. A detailed investigation regarding quality of measurements has been carried out taking into consideration the effect of a wide range of climatic variations. Experimental values of fill-factor and peak power over a broad range of insolation spectrum have been obtained which yield a fairly consistent pattern for varying capacities of PV modules. Regression analysis for linearity check has been done to establish the effectiveness and reliability of the developed characterization system.

“…On the above backdrop, authors of this paper have introduced a new technique where supercapacitors have replaced the capacitors with the plotting time modeled out as a function of four basic electrical parameters short circuit current (I sc ), open circuit voltage (V oc ), maximum current at maximum power point (I m ) and maximum voltage at maximum power point (V m ) along with the effective series resistance (ESR) value of the SC bank. This is reported in details in an earlier publication [5].…”

“…Thus, the next section is essentially devoted to a review of the existing metrological approaches practiced in PV engineering for establishing the specific merits of the supercapacitor (SC) based method introduced by the authors. Here, supercapacitors have been used in the area of PV metrology for the first time as the load to the PV generators [3][4][5].…”

Supercapacitors have been used for the first time as load to PV cell/modules for characterizing their behavior. In this paper, a novel and essentially simple design of a V–I plotter is attempted with a bank of super capacitors (SC) as the load to the PV modules of varying capacities. The distinct advantages of the SC's over the erstwhile capacitors have been comparatively experimented. Finally, an elaborate regression analysis (RA) of principal electrical parameters have yielded consistently high values exceeding 0.993 experimental evaluation of quality parameters like fill-factor (FF) and performance ratio (PR) have yielded a range of 70–79% while PR values frequently ranges from 90% to 99%. Suitability of poly-Si PV modules at the level of PV panel configurations have been ascertained through experimental estimate of series and parallel relative power loss (RPL) values. Typical values below 2% obtained for widely varying climatic level is also a quality indicator for the new metrology in question. Such a prototype I–V plotter is expected to be duly considered for commercial testing applications in PV industries.

“…Where G 0 is the extraterrestrial irradiance in higher layers of the atmosphere in the horizontal plane for a particular day in a year. Clearness Index impacts are described more accurately by Tadeusz Rodziewicz et al [12] Principles of charging and discharging of SC"s have been described in detail with relevant block diagrams in earlier publications [6,7,8,9]. However, careful configuration of SC banks are to be worked out depending on Device under Test (DUT) specifications and this is detailed in the next sub-section.…”

“…In the Indian continent, the lion's share in upcoming PV arrays is constituted from polycrystalline PV modules in the recent past [5]. Accordingly, the authors have initiated the testing of various wattage poly-Si modules with their novel and user-friendly measurement set-up [6,7,8,9]. In the aforesaid background, authors have carried out extensive measurements and subsequent analysis on poly-Si PV modules of assorted wattages during monsoon seasons [10].In continuation of such studies, further investigations are elaborated in this paper during winter and early summer of 2019 in this part of the sub-continent.…”

An appropriate number of series-connected supercapacitors (SC) forming an SC bank has been used for the first time as the load to PV generators in course of their electrical characterization. Exhaustive estimates of standard PV parameters along with figures of merits like Fill-factor(FF) and performance ratio(PR) have yielded consistent results under naturally varying levels of insolation and ambient temperature prevalent in West Bengal of India. Regression analysis of selected PV parameters has indicated values above 0.997 for poly-Si PV modules which currently constitute the only essential building blocks for PV arrays in the Indian subcontinent. Work is in progress for the adoption of this simple, user-friendly, and easily scalable I-V plotter in PV Indian industries and field trials.
