Floating photovoltaic systems (FPV) are one of the emerging technologies that able to support “green” energy transition. In Greece, environmental impact assessment such projects is still under early development. The scope present study was provide insights into potential impacts a small-scale FPV system on water quality oligotrophic Kremasta Lake, an artificial reservoir. For this reason, hydrodynamic and model employed. results showed parameter variations were insignificant limited only in immediate area construction gradually disappeared toward shoreline. Likewise, variation restricted first few meters depth column eliminated onwards. temperature slightly decreased close proximity installation. Average annual dissolved oxygen, chlorophyll-a, nutrient concentrations predicted not change considerably after panels’ construction. can attractive alternative for production reservoirs, especially regions land use conflicts associated with allocation Given data long-term projects, robust monitoring programs essential. These initiatives rely public support, making collaboration between stakeholders local community crucial.

The development of novel renewable energy technologies, such as floating photovoltaics (FPVs), is expanding, but their environmental consequences remain understudied. FPVs physically alter freshwater ecosystems by limiting light and wind penetration at the lake surface, while providing new substrates for biofilm development, including diatoms. Diatoms are essential to primary production carbon cycling in aquatic systems, however, composition diatom assemblages on FPV structures remains unexplored. This study aimed characterise colonising floaters compare them with those pelagic benthic compartments gravel pit lakes. Results showed significantly lower taxonomic richness diversity floaters, followed assemblages, highest values observed habitats. Community also differed between three compartments. across all habitats, its dominance was particularly pronounced (72%), compared 54% 32% compartments, respectively. As a low-profile, disturbance-tolerant taxon, Achnanthidium may thrive low-light conditions created shading. It can serve good water quality indicator, baseline studies needed assess whether reflects positive By creating artificial habitats zone, modify patterns pelagic-benthic coupling that be investigated.

Floating photovoltaic (FPV) systems are a rapidly expanding renewable energy technology, yet their potential ecological impacts, particularly cross-ecosystem effects, remain poorly understood. This review synthesises current knowledge on organic matter (OM) dynamics and carbon (C) fluxes in lake ecosystems, examining how FPV installations may influence C cycling, insect emergence, greenhouse gas (GHG) emissions. can alter OM availability, shifting the balance between autochthonous allochthonous inputs. In short term, installation increase deposition due to rapid decline of primary producers riparian vegetation removal. Long-term effects uncertain but could drive metabolic regime shifts toward autotrophy or heterotrophy, depending initial conditions. These changes, combined with reduced oxygen temperature, significantly aquatic food webs, modify GHG fluxes, dynamics. Increased sedimentation enhance production, while delayed emergence weaken transfer terrestrial ecosystems. Declines emergent biomass impact predators, such as bats birds, triggering cascading effects. Overall, reshape across aquatic–terrestrial boundaries, impacts varying by coverage lake-specific factors. There is an urgent need for ecosystem-scale studies long-term data assess FPV-induced changes mitigate its biodiversity global cycle.

Abstract Floating photovoltaic (FPV) systems are designed for free water surface installations to provide a feasible solution places with no availability of land areas and avoid land-use conflicts caused by conventional solar energy farms. However, lakes reservoirs essential ecosystem services like supply biodiversity support. In this regard, there was lack long-term high-frequency monitoring data important parameters influenced FPV installation such as photosynthetically active radiation (PAR) dissolved oxygen (DO). Temperature, despite being more reported, is consensus on increase or decrease values below the FPV. study, we conduct comprehensive field assessment accurately quantify temperature variations (at weather station, modules, between modules within water), DO, PAR installed in reservoir. High-frequency sensors indicated that 94.7% reduction compared lake reference slight differences were found measurements monthly daily averages system covers less than 1% reservoir surface. addition, microclimate due module warming created 12% greater station measurements. The fluctuation throughout different time frequencies showed processes according complex interactions among meteorological conditions, configuration, site-specific factors.

The global cumulative installed PV capacity is anticipated to surpass 2 TWp by the end of 2024, which an increase in three orders magnitude from 1 GWp at 2004. Depending on energy transition scenarios, up 8 kWp per capita have be operational 2050 globally. In Europe, this could even 50% higher, and will consequences decisions regarding where install capacity; thus, these significantly impacted. This paper gives overview technology options for installing systems areas already used other human activities as well integrating them into ships vehicles without acquisition extra land. focus situations within European Union, such land competition, presents innovative solutions.
