WebTherefore, 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. Solar reflectance is also called total solar reflectance (TSR). TSR is commonly used by the industry, but in the ASTM standards, solar reflectance is the standard name used, instead of TSR. i\u0027m about to pull up
