“…In any case FPVs is a major perturbation to water body's functions. Reference [6] have investigated the thermal and electrical performance of FPVs compared to terrestrial PVs. The authors stated that when the water body was partially covered with the FPV system the water evaporation was reduced by 17% while when it was fully covered it was reduced by 28%.…”

“…It has been developed rapidly during the last decade due to their benefits compared to ground-mounted PVs [3], [4]. Although their installation cost is slightly higher compared to the cost of terrestrial PVs their electricity yield is higher while the water evaporation from the reservoirs is lower and less land resources are used [4]- [6]. FPVs are installed on the surface of inland water bodies usually covering part of the water surface.…”

Floating photovoltaics consists of a new and fast-growing technology worldwide. Installations of these novel green energy systems have not been developed so far in Greece. The aim of the current work is to investigate the potential of installing floating photovoltaic systems in Greek water bodies. The existing water reservoirs in Greece have been identified while their water surface that allows the installation of solar panels, the nominal power of the floating photovoltaics and the generated solar electricity have been estimated. The nominal power of floating photovoltaics which can be installed in the existing 128 water reservoirs in Greece covering 10% to 30% of their surface varies between 4.77 GWp to 14.31 GWp while the annual generated electricity at 6,435.2 GWh to 19,305.6 GWh corresponding at 12.40% to 37.20% of the total annual electricity consumption in the country. The annual water evaporation savings, due to installation of floating photovoltaics, have been calculated at 71.55 mil. M3 to 214.65 mil. M3 while the increased annual electricity gain at 321.76 GWh to 1,930.56 GWh. The results indicate that significant amounts of electricity can be generated with floating photovoltaics installed in water reservoirs in Greece. They could be useful to policy makers who are developing policies to achieve net zero carbon emissions by 2050 in Greece and to energy companies who are willing to invest in these novel green energy technologies.

Solar energy is considered as one of the clean and sustainable energy sources. As known, big portion of the energy demand in industrial processes are generally met by fossil energy sources. Utilizing renewable and sustainable energy technologies in industrial facilities can decrease negative environmental effects. In this study, applicability of a rooftop solar energy generation system in an industrial building has been analyzed. In the simulation process, PvSOL software has been employed. Considering available areas on the roof of the facility, solar electrical energy generation system with installed power of 573.75 kWp was planned and simulated. Moreover, economic analysis results of the proposed rooftop solar energy system were presented within the scope of this research. According to the economic analysis outcomes, payback period of the proposed rooftop energy system was achieved less than 4 years.

“…A decrease in module temperature can increase system efficiency and the amount of energy produced [3]. [4] observed that the front temperature of the FPV modules is 2-4% lower and the back temperature is 5-11% lower compared to similar On Ground PV modules. Since FPV systems create shade on the water surface, the evaporation rate of the water is lowered by approximately 25-70% [5].…”

In this study, remote sensing (RS) was used to determine the 20-year area and shoreline changes of Demirköprü Dam reservoir. Using a geographical information system (GIS) solar analysis tool, annual and monthly total global horizontal irradiance (GHI) values were calculated within the area of the reservoir’s shorelines based on 20-years of observations. The regional theoretical capacity factor (RTCF) proposed in this study was modelled using total annual GHI values. The water surface was divided into four regions using RTCFs 94.97%, 4.92%, 0.08%, and 0.02% of the total water surface area were classified as RTCF21, RTCF20, RTCF19, and RTCF18, respectively. The annual electrical energy potentials per unit for each RTCF were calculated. The novel method developed in this study for determining the optimum location of FPV SPPs to be installed on water surfaces reveals the importance of evaluating land topography and considering annual patterns of shading.
