“…The authors however highlighted that the FPV module design could favor or obstruct the heat transfer, affecting the U-value of the system. These conclusions were confirmed by a different work (Dörenkämper et al, 2021), which analyzed data from FPV and LPV systems in the Netherlands and Singapore. In this case, U-value as high as 57 W/m 2 K were found for some specific designs (Dörenkämper et al, 2021).…”

“…However, PVSyst recommends using the heat loss coefficient U without wind dependency. In addition, limited differences have been reported between the two approaches when used to simulate the field performance of FPV systems (Dörenkämper et al, 2021).…”

“…The result was attributed to the lower wind speeds registered on that basin compared to land. An analysis of FPV systems deployed in the Netherlands and in Singapore showed that some FPV geometries do not achieve better thermal behaviors than LPV (Dörenkämper et al, 2021). Therefore, modelers and analysists cannot assume that FPV would always work at lower operating temperatures than LPV.…”

There is a huge interest worldwide related to continuously increasing the use of renewable energy sources (RES) for electricity generation. Romania, at this moment, even though it has to attain a share of 30.7% of RES from total energy consumption by 2030, does not have any major investment project of this kind in the near future. Photovoltaic (PV) is one of the most promising technologies, with decreasing prices for PV panels but with the disadvantage of large, needed surfaces. This study presents a solution to install PV panels where there is a need for electricity, in a large city, by using the surface of a reservoir. “Lacul Morii” Reservoir in Bucharest is the choice for the case study. The insolation and the possibility to install floating PV, as well as electricity generation, benefits for water quality and carbon dioxide (CO2) emissions reduction are assessed, and even the installation of charging stations for electric bikes and cars. The results are very promising, and the main conclusion is that, after its realization, the floating photovoltaic (FPV) plant on “Lacul Morii” Reservoir will be a source of clean electricity and a demonstration project on how to benefit from solar energy to produce electricity in large cities where there are reservoirs.

Summary In this study, lab‐made modified graphite cathodes were used to design and implement floating PV assisted alkaline electrolysis cell. The influence of temperature on PV performance was studied both experimentally and theoretically, and the PV module performance was investigated in floating as well as non‐floating modes. Power generation of floating PV panel and non‐floating PV panel at four different air temperatures was examined. Although there was no substantial improvement in power generation at 6°C or 16°C, values improved by 6.25% and 10.75% at 24°C and 37°C, respectively. For alkaline electrolysis cell part of this system, the graphite (G) cathode was galvanostatically coated with nickel (G/Ni) and decorated with cobalt nano‐particles (G/Ni/Co). The characterization of the electrode was achieved using X‐Ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The Co(111)‐decorated Ni was determined by XRD, the electrode surface was very rough in FE‐SEM micrographs, the detected features provided a larger contact area that supported the formation of simultaneous electrochemical reactions. The electrochemical behavior of electrodes were determined in 1 M KOH by cyclic voltammetry (CV). The modified cathode (G/Ni/Co) enhanced the hydrogen production performance owing to lower hydrogen onset potential. Electronic structure calculations were carried out in order to investigate water as well as proton adsorption on a Co‐decorated Ni(111) surface. Density Functional Theory (DFT) calculations identified the role of Co cluster and Ni surface on water and proton adsorptions. According to our knowledge of the literature to date, the practical and theoretical analysis of a floating PV assisted‐an alkaline electrolysis system that worked with the laboratory‐made electrodes has not been performed before. Results showed that floating PV panels were beneficial than land mounted panels and the G/Ni/Co enhanced the hydrogen generation performance of the system.
