The portable solar reflectometer is calibrated using specimens of known solar … WebbThe benefits of solar reflective paint (also called heat-reflective paint or anti-glare paint) start with the passive quality of the paint to reflect heat. In other words, once applied, the paint works to reflect the solar rays when the sun is out. The paint does not need any …
