“…They also mentioned that the global electricity generation potential of hybrid FPV-hydropower systems has been estimated in the range of 4,251 TWh to 10,616 TWh annually. Abdelal [14] has assessed the water quality and evaporation reduction in semi-arid regions due to floating solar photovoltaics. The author stated that the quality of water was not affected while a reduction of around 60% in water evaporation was observed.…”

The role of solar energy for heat and power generation is very important during the transition to a low carbon economy. Floating solar photovoltaics consists of a novel and rapidly growing sustainable energy technology having many advantages compared to conventional ground-mounted solar photovoltaic systems. Aim of the current research is the investigation of the possibility of installing floating photovoltaics in the existing water reservoirs in the island of Crete, Greece. Data on existing water dams in Crete were used and the nominal power of floating photovoltaics as well as their potential for electricity generation were evaluated. It has been estimated that the nominal power of floating photovoltaics that can be installed in these water dams, with coverage ratio at 0.1 to 0.3, varies between 55.76 MWp to 167.3 MWp while the annual electricity generation from the floating photovoltaics varies between 78.3 GWh to 234.9 GWh. The annual electricity generation from the abovementioned floating panels corresponds at 2.57 % to 7.72 % of the annual electricity consumption in Crete in 2018. Our study indicates that floating solar photovoltaics can be installed in the existing water dams in Crete generating significant amounts of green electricity having also various environmental co-benefits. The current work could be useful to policy makers, local and regional authorities, energy companies as well as to owners of the water dams in the island.

“…They also mentioned that by covering 30% of the water surface with solar panels the water evaporation can be reduced by 49%. Reference [14] has assessed the impacts of FPVs on water quality and evaporation reduction in semi-arid regions. The authors stated that the use of FPVs in agricultural ponds is very beneficial resulting in solar electricity generation and in water evaporation savings.…”

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.

“…In addition to other countries, FPV installations have been made in the USA, China, Japan, India, Korea, Singapore, Brazil, Norway and the United Kingdom. In regions with inadequate grid infrastructure, such as Sub-Saharan Africa and some developing regions of Asia, floating solar might be especially advantageous [10]. The need to cool solar PV plants is one of the biggest obstacles, though, as panel heat lowers electrical performance [11].…”

The demand for power will have doubled by the year 2050. Solar energy currently meets a small percentage of the world's demand, despite its enormous potential as an eco-friendly method for producing electricity. Utilizing land resources sustainably is one of the challenges. As an alternative, floating PV (FPV) plants on bodies of water, such as a dam, reservoir, canal, etc., are gaining popularity worldwide. This project aims to design a hybrid floating solar system that can produce renewable energy in light of the above. Among the hybrid technologies addressed are FPV & hydro systems, FPV & pumped hydro, FPV & wave energy converter, FPV & solar tree, FPV & tracking, FPV & conventional power, and FPV & hydrogen. The review also summarises the main benefits and drawbacks of hybrid floating solar PV (FPV) systems. The hybrid FPV technologies with hydro and solar energy input were some of the most promising ones for producing power efficiently. The important ideas in this paper advance understanding and could serve as a catalyst for the creation of environmentally friendly, sustainable hybrid floating installations
