aces.nmsu.eduFinally, the reflectance of the ground surrounding the solar panels must be taken into account because sunlight can reflect off of a surface onto a tilted panel and alter the total solar irradiance collected. The local and solar times, as well as the date entered in the previous sheet, are shown in the box above the green cells as a reference.
Reflectance in Thin Films - Materion
materion.comThe reflectivity or reflectance (R), of a surface is an intrinsic optical property of a surface. In many optical, electrooptic, telecommunications, solar concentrator and architectural applications, reflectance must either be controlled (reduced or enhanced), or the color of the object changed (e.g., given a “gold” color).

Energy Interactions with Atmosphere and Earth Surface
civil.iisc.ernet.inThe reflectance characteristics of earth surface features may be quantified by measuring the portion of incident energy that is reflected. This is measured as a function of wavelength, and is called spectral reflectance, R .
