The ground reflectance (also called albedo) is the fraction of solar radiation incident on the ground that is reflected. A typical value for grass-covered areas is 20%. Snow-covered areas may have a reflectance as high as 70%. This value is used in calculating the radiation incident on the tilted PV panels, but it has only a modest effect.
