Solar reflectance of glass
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. WebJun 27, 2016 · Diffuse daylight reflectance = 0.200 (20.0%) Specular daylight reflectance = 0.015 (1.5%) Some customers expect that the specular daylight reflectance should be 0.216 – 0.200 = 0.016 (1.6%) and suspect that there is a typo in the test report. Our daylight reflectance test reports are generated by in-house software automatically.
