“…At the same time, to further support the notion of minimal intervention, our reference scenario assumes a coverage percentage for floating PV systems equal to 1% over the available area of each lentic water system examined. The adopted value is in line with, or lower than, the respective assumptions made in similar, recent research [21], and quite lower than the coverage coefficients proposed by local market associations, in the order of 5%.…”

According to the recent revision of the Greek National Energy and Climate Plan, the country sets out to accomplish an ambitious target concerning the integration of renewables in the local electricity mix during the ongoing decade, at the levels of 80% by 2030. This implies the need to more than double the existing wind and PV capacity at the national level, which in turn introduces numerous challenges. Amongst them, spatial planning for new RES installations seems to be the most demanding, with the adoption of novel technological solutions in the field of RES potentially holding a key role. New technologies, like offshore wind and floating solar, are gradually gaining maturity and may offer such an alternative, challenged at the same time however by the need to entail minimum disruption for local ecosystems. To that end, we currently assess the theoretical potential of floating PVs for lentic water systems of the Greek mainland. We do so by looking into 53 different lentic water systems across the Greek territory that meet the constraint of 1 km2 minimum surface area, and we proceed with the estimation of the relevant floating PV capacity per system under the application of a minimal intervention approach, assuming PV coverage of 1% over the total lentic water system area. In this context, our findings indicate a maximum, aggregate theoretical capacity that could exceed 2 GWp at the national level, with the respective annual energy yield reaching approximately 4 TWh or, equivalently, >6% of the country’s anticipated annual electricity consumption in 2030. Finally, our results extend further, offering a regional level analysis and a set of policy directions and considerations on the development of floating solar in Greece, while also designating the energy merits of floating PVs against similar, land-based installations.

“…The elimination of terrestrial land occupation, as indicated in the study, aligns with findings from previous research. [ 22 ] This outcome also plays a role in maintaining the sustainability of urban planning and controlling land prices in urban areas. [ 6 ] The calculated installation cost and return‐on‐investment period for the FSPV system align with results from various studies, considering its energy production capacity.…”

“…[ 6 ] Another study focused on FSPV's technical potential in irrigation ponds and water infrastructures, finding that it prevents the occupation of 12 km 2 of land and saves 8.8 ×106 m 3 per year of evaporating water. [ 22 ] In a 2020 study, the electricity generation and water‐saving capacity of a 1.14 MW FSPV system covering 30% of a reservoir were analyzed, demonstrating energy production, water savings, and CO 2 reduction benefits. [ 23 ] Additionally, a study on FSPV's technical potential in artificial water bodies found that covering 1% of eligible areas could generate energy equivalent to about 12.5% of national electricity generation.…”

This study assesses the impact of implementing a floating solar photovoltaic system (FSPV) on the Turgutlu irrigation pond in Sakarya, Turkey, aiming to reduce energy expenses in agricultural irrigation and promote sustainability in farming. Two scenarios are developed to evaluate the FSPV, focusing on CO2 emissions mitigation, energy generation potential, evaporation reduction, conservation of terrestrial land, effects on agricultural production, decreased reliance on fossil fuels, and associated costs and return on investment (ROI). In the first scenario, the FSPV is expected to generate 7168 MWh of energy, preventing the emission of 4520 tons of carbon, and reducing annual evaporation by 6686 m3. In the second scenario, the FSPV's energy output is estimated at 99 MWh, preventing 64.2 tons of carbon emissions, and reducing annual evaporation by 94.4 m3. These findings provide valuable insights at the regional level, presenting a compelling case study for potential replication in other irrigated agricultural regions.

“…(d) Agricultural less land use: By putting solar panels on or over unused water bodies, reservoirs, lakes, water treatment plant reservoirs, and agricultural reservoirs, it is possible to minimize the use of the precious land needed for agriculture or other crucial human use. FPV could be ideal for those countries which are smaller in size and have agriculturally based economies [74]. (e) Early morning production: According to (NRG 2010), due to the mitigation effect, the panels start producing earlier in the winter season.…”

Energy and water poverty are two main challenges of the modern world. Most developing and underdeveloped countries need more efficient electricity-producing sources to overcome the problem of potable water evaporation. At the same time, the traditional way to produce energy/electricity is also responsible for polluting the environment and damaging the ecosystem. Notably, many techniques have been used around the globe, such as a photovoltaic (PV) cooling (active, passive, and combined) process to reduce the working temperature of the PV panels (up to 60 °C) to improve the system efficiency. For floating photovoltaic (FPV), water cooling is mainly responsible for reducing the panel temperature to enhance the production capacity of the PV panels, while the system efficiency can increase up to around 30%. At the same time, due to the water surface covering, the water loss due to evaporation is also minimized, and the water evaporation could be minimized by up to 60% depending on the total area covered by the water surfaces. Therefore, it could be the right choice for generating clean and green energy, with dual positive effects. The first is to improve the efficiency of the PV panels to harness more energy and minimize water evaporation. This review article focuses mainly on various PV and FPV cooling methods and the use and advantages of FPV plants, particularly covering efficiency augmentation and reduction of water evaporation due to the installation of PV systems on the water bodies.
