WebSolar reflectance is the fraction of solar radiation that is reflected by a surface. For opaque materials, the incident solar radiation is either absorbed or reflected. Therefore, the sum of solar absorptance and solar reflectance is 1. For the example above, the solar reflectance of the surface is 1 – 0.60 = 0.40.
