What is Floating photovoltaic (FPV)?

In recent times, the escalating global demand for sustainable and renewable energy sources has catalyzed the exploration and development of innovative technologies, among which floating photovoltaic (FPV) systems emerge as a particularly promising solution. These systems exploit solar energy by deploying PV panels on water surfaces.

How do water-surface photovoltaic systems affect community composition?

We found that water-surface photovoltaic systems decreased water temperature, dissolved oxygen saturation and uncovered area of the water surface, which caused a reduction in plankton species and individual density, altering the community composition.

Can Floating photovoltaic panels reduce water evaporation?

A detailed review of floating photovoltaic (FPV) technology was published in 2019. It speaks about the potential of efficient operation of photovoltaic (PV) panels and their utilization to reduce water evaporation [ 4 ].

How do PV panels affect water quality?

Large areas of PV panels cast shadows on the water surface and thus can reduce light availability to waterbodies, and floating materials on the water surface reduce contact between the air and waterbody, which may lead to reductions in water temperature and dissolved oxygen 17, 18. These changes might impact aquatic organisms.

What factors should be considered when designing Floating photovoltaic systems?

Wind, waves, and currents. Environmental factors must be taken into account when designing Floating Photovoltaic (FPV) systems. As a promising and emerging renewable energy source, FPV systems are undergoing a transition in development, moving from inland water environments to marine environments.

Should solar panels be placed over water bodies?

Placing solar PV panels over water bodies (using, for example, floating panels or water-body-spanning infrastructure) conserves water by reducing evaporation losses through effects on incident solar radiation and surface wind speeds 7, 8, 9, 10, 11, 12, 13.
