Are floating solar photovoltaics coming to sea?

Introduction The deployment of floating solar photovoltaic arrays (floatovoltaics) in freshwater environments has risen exponentially, and now installations are beginning to appear at sea (SERIS, 2019).

Can floating solar technology be used in rough offshore environments?

Taking floating solar technology into rough offshore environments requires that the existing solar PV modules can resist salty water and withstand strong currents and wave and wind loads. Additionally, a cost competitive concept for the floating structure needs to be developed.

Can floating solar photovoltaics be used in marine waters?

Various designs for floating solar photovoltaics are appearing in marine waters. Insight from freshwater areas is not readily transferable to marine environments.
