Investigating the Impact of Ground Albedo on the Performance of PV Systems
  Several factors influence the energy generation of Photovoltaic (PV) installations. A ground albedo value of 0.2 is widely accepted and is used in modelling of PV systems. Foreground surfaces may have different albedo and hence a constant albedo value is unsuitable. This paper analysed a real PV facade of a university building. The results show, that in the present case, using a constant albedo value may underestimate the incident ground reflected radiation by 31%. A discussion is also provided on applying white cool paint on foreground surfaces to further increase the receipt of reflected-radiation on PV modules
