Benchmarking study between capacitive and electronic load technic to track I-V and P-V of a solar panel

Abstract

<p>To detect defects of solar panel and understand the effect of external parameters such as fluctuations in illumination, temperature, and the effect of a type of dust on a photovoltaic (PV) panel, it is essential to plot the Ipv=f(Vpv) characteristic of the PV panel, and the simplest way to plot this I-V characteristic is to use a variable resistor. This paper presents a study of comparison and combination between two methods: capacitive and electronic loading to track I-V characteristic. The comparison was performed in terms of accuracy, response time and instrumentation cost used in each circuit, under standard temperature and illumination conditions by using polycrystalline solar panel type SX330J and monocrystalline solar panels type ET-M53630. The whole system is based on simple components, less expensive and especially widely used in laboratories. The results will be between the datasheet of the manufacturer with the experimental data, refinements and improvements concerning the number of points and the trace time have been made by combining these two methods.</p>

Structural and Physicochemical Properties of Dust and Their Effect on Solar Modules Efficiency in Agadir-Morocco

“…This device exhibits a resolution on the voltage of 0.01 V in the range of 4 to 60 V and on the current intensity a resolution of 0.001 A for intensity measurements up to 6 A. The uncertainty given by the manufacturer is 0.02% [22].…”

Utilization of MOSFET Transistor to Characterize PV Panels under Dust: Study Area Agadir-Morocco

“…JASCO V730 UV-Vis spectrophotometer was used to compare the evolution of optical transmittance of light (300-1100 nm) as a function of dust density. The electrical circuit proposed in this article is realized with an Arduino UNO board, as a unit of acquisition, control, and transfer of data (Ipv and Vpv), in real time, to a computer via the PLX-DAQ tool [12,13]. The Arduino module generates a PWM signal, then this signal is injected to an RC filter to control the variation of the voltage VGS of the MOSFET [14].…”
