“…Depending on climate specifications of each geographic area, many clean sources of energy solutions can be advised [2], [3], with the aim of solving the energy crisis, climate change, and global warming, the most abundant renewable sources of energy is solar energy [4], it can be exploited to produce electricity by using photovoltaic solar panel or concentrated photovoltaic, or to produce thermal energy by using solar concentrators such as Fresnel mirrors concentrators [5], parabolic trough collectors [6]. Solar trackers systems are required in the cases of solar concentration systems such as Fresnel mirrors concentrators, parabolic trough collectors and concentrated photovoltaic, while in the case of photovoltaic panels, the sun trackers are not mandatory, but allows better performances that can reach 40 to 60% [7], [8] in comparison to a static photovoltaic panel, depending on weather conditions.…”

<span lang="EN-US">The aim of this paper is to study the effect of dissimilarity of the intrinsic characteristics of the light dependent resistor (LDRs) on optical sun tracking systems, designed for solar power concentration applications such as parabolic trough collectors, Fresnel mirrors concentrators, and concentrated photovoltaic, a comparative study was done between a sun tracker based on LDRs chosen randomly with and without an initial calibration of the offsets, and a sun tracker based on LDRs selected meticulously thanks to a black box test bench, developed especially for this purpose. By choosing two light dependent resistors randomly, the dissimilarity between them can reach 23.2%, which cause a bad sun tracking even with initial offset calibration, in the other hand, and by the use of selected LDRs using the test bench, the dissimilarity drops to 0.06%, which meets requirements of solar power concentration systems.</span>

“…There are several methods of dual and single-axis tracking methods that have been done previously by others. Examples are microprocessor-based tracking [5], using webcam and computer controlled [9], GPS based tracking using astronomical equation [10,11] or solar maps [12], RTC-based algorithm [13], simple light dependent resistor (LDR)-based tracking [14], or thermal expansion of material connected to a lever [15]. Solar panel systems may be self-sustained or powered up through external power.…”

<p>Power output from a small solar panel can be affected by its power consumption when it consumes power from the solar panel. There has been a lack of proper research and experiment in the use of small solar panel with tracking systems. Its significance was detailed in this paper where the voltage output are compared with those which were externally powered. The solar trackers and a microcontroller have been designed and fabricated for this research. Due to the use of the tracking system (single axis and dual axis), the power consumption varies from one to another and its effect on the voltage output. Several experiments have been conducted and it was concluded that small solar panels are not efficient enough to utilize with tracking capabilities due to an increase in power consumption. The externally powered system was found to generate 18% more output compared to a selfsustaining system and that the increase in average power consumptions compared to a fixed panel were 31.7% and 82.5% for single-axis and dualaxis tracker respectively. A concrete evidence was made that utilizing solar tracking capabilities for low power rated solar panel is unfeasible.</p>

“…The outdoor performance of photovoltaic (PV) solar energy systems faces several challenges for its better functioning and interpretation of various effects, such as degradation (Cotfas and Cotfas, 2019;da Fonseca et al, 2020;Cornaro and Musella, 2013), temperature increase (Ostenwald et al, 2015;Carrillo et al, 2017), reflections, angular losses and variations in air mass (Amillo et al, 2015;Senthilarasu et al, 2015). To keep up with this evolution, not only module technologies need to be improved, but also inverter technologies, solar tracking systems, installation and maintenance procedures (International Renewable Energy Agency -IRENA, 2019; Hashemzadeh, 2019;Ibrahim et al, 2018). In addition, deepening the understanding of the performance of cells fabricated using different technologies (especially the influence of the spectral changes (Ishii et al, 2011)) is relevant for better experimental procedures and to the development of the technologies.…”

Assessment of spectral effects on outdoor characterization of PV modules using silicon reference cells with spectral filters

This article describes outdoor temperature-controlled measurement of various photovoltaic (PV) modules fabricated using different technologies and using reference cells with spectral filters. Short-circuit current measurements of all PV modules and reference cells were recorded simultaneously using 16-bits Keysight digitizers and high-resolution Agilent multimeters. The spectral incompatibility factor was calculated considering the spectral response of each device and the spectrum measured outdoors. Corresponding spectra were also generated by the simple model of atmospheric radiative transfer of the sun SMARTS2 and were additionally used to compare the spectral incompatibility factors. The validation of the measurement method was demonstrated by comparing the incompatibility factor calculated with variation of the short-circuit current relationship between the device under test and the reference cell over time. Additionally, it was evaluated how the relationship between spectral variation of irradiance and the spectral response of different technologies affects the productivity in thin-film modules. Main observation from measurements (performed in Labsol) was that a-Si/μ-Si, CdTe, and triple a-Si junction converted 0.21%, 2.47%, and 3.65% more irradiation into electric current (in summer), respectively, compared to c-Si technology. The PV CIGS module converted on average 0.26% more irradiation into electric current in winter compared to c-Si technology. The results help to understand the spectral effects on the working of outdoor PV module and the relationships between measured and modeled spectra, as well as errors introduced by the spectral incompatibility factor.
