Abstract
Photovoltaic (PV) module performance is primarily characterized by their current-voltage (
I-V
) measurements. However, the data obtained mostly contains errors. Commercial
I-V
curve tracking units are generally expensive, hard to transport, slow to respond, and limited at low irradiations. This article proposes a novel
I-V
tracer (SEPIV) based on an optimized single-ended primary inductance converter. The SEPIV comprises a linear variable dc load connected to the solar panel's output. In this study, the experimental performance of the SEPIV was compared with the outcomes of commercial and lab devices, which are PVPM 1000 C 40 (PVPM) and WAVELABS SINUS-3000 PRO, respectively. SEPIV's accuracy matched lab units and surpassed PVPM's. As a highlight of this study, the introduced setup can capture the
I-V
curves of PV modules up to 650 W, a maximum
V
OC
of 60 V, and a maximum
I
SC
of 20 A. In contrast to commercial units, the SEPIV measurement does not depend on irradiation level. Moreover, it has the Internet of Things capability through a Wi-Fi connection for remote measurement.
期刊介绍:
The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
