Foam-based floating PV system for cold climates - pv magazine Global

Researchers at Canada's Western University demonstrated that a foam-backed floating solar PV system with an air-bubbler can operate effectively through freezing winters, keeping ice at bay with minimal energy use. The system produced up to 2.7% more annual energy than conventional PV models, reduced water evaporation, and showed strong economic potential with a payback period of about 4.2 years under high electricity prices.
