“…Popov et al [55] used the virtual instrumentation for PVT hybrid characterization, also including uncertainty calculations. The characterization system was based on a LabJack UE9 DAQ and a self-developed extension board that offers 32 channels for temperature measurements using Pt100 sensors, 16 differential low-voltage channels for DC current, solar irradiance, thermocouple measurements, 10 voltage channels for AC voltage and current measurements, 8 counter channels for flow rate measurements and 1 wire interface that allows communication with up to 128 DS1820 temperature sensors.…”

Finding new sustainable energy sources or improving the efficiencies of the existing ones represents a very important research and development direction. The hybridization approach is one solution for increasing the efficiency of the existing energy sources. In the case of photovoltaic technology, the hybridization of the photovoltaic panels (PV) with thermoelectric generators (TEGs) has become a more interesting solution for the research community in the last decade. Thus, a comprehensive review of the characterization methods and instruments used in PV-TEG hybrid system study represents the objective of this work. PV and TEG equivalent circuits are presented. The instruments and software applications used for the measurements and simulations are presented and analyzed. The analysis of the literature reveals that there are many papers that offer partial or no information about the instruments used or about the measurement quality (accuracies, uncertainties, etc.). In hybrid system modeling, the preferred software applications are MATLAB (MathWorks, Natick, MA, USA) and COMSOL Multiphysics (Comsol, Burlington, MA, USA), while for experimental studies based on computers, LabVIEW (NI, Austin, TX, USA) is preferred. This review work could be interesting for researchers and engineers who are interested in finding solutions for characterizing or monitoring hybrid system components, but it is not limited to these.

“…As a result, controlling the temperature of a PV module is critical, which can be accomplished through a variety of cooling techniques [14][15][16][17]. Either passive cooling or active cooling can be used [18][19][20][21][22]. The active cooling method employs Sustainability 2021, 13, 6084 2 of 12 water or nanofluid cooling methods [23], whereas the passive system employs thermoelectric Peltier modules [24] or vacuum insulation [25][26][27] to minimize the cumulative surface heat induction on PV panels.…”

Solar irradiation in hot-arid climatic countries results in increased temperatures, which is one of the major factors affecting the power generation efficiency of monocrystalline photovoltaic (PV) systems, posing performance and degradation challenges. In this paper, the efficiency of a water-flow cooling system to increase the output of a monocrystalline PV module with a rated capacity of 80 W is studied from both energy and exergy perspectives. The energy and exergy tests are performed for each season of the year, with and without cooling. The energy and exergy efficiencies, as well as the commodity exergy values, are used to compare the photovoltaic device with and without cooling. The findings are based on the experimental data that were collected in Tehran, Iran as an investigated case study in a country with a hot-arid climate. The findings show that when water-flow cooling is used, the values of the three efficiency metrics change significantly. In various seasons, improvements in regular average energy efficiency vary from 7.3% to 12.4%. Furthermore, the achieved increase in exergy efficiency is in the 13.0% to 19.6% range. Using water flow cooling also results in a 12.1% to 18.4% rise in product exergy.
