On the Effect of Dynamic Albedo on Performance Modelling of Offshore Floating Photovoltaic Systems

Abstract

In this paper, the effect of dynamic albedo on modelling energy generation of a floating offshore photovoltaic system is quantified, for a system assumed to be installed at the North Sea. The dynamic albedo is modeled as a function of solar irradiation, wind speed and solar zenith angle at an hourly time resolution. The energy output of a floating offshore PV system is compared considering two scenarios (i) implementing constant albedo and (ii) implementing a modeled dynamically varying albedo. The quantified results show that the system performance in case of a varying albedo is larger by about 1.03% compared to using a constant albedo.
