Solar Panel Glare: Do I need to worry about glare from solar panels?
Solar panels often have reflective glass surfaces and PV ribbons, when sunlight hits these glass surfaces and PV ribbons, it can be reflected, leading to glare. Mounting angle relates closely to glare. Firstly, the lower the angle of the sun, the more likely it is for photons to strike reflective surfaces, causing glare. Secondly, the lower the ...

Solar Reflectance
An ordinary white material reflects most of the solar energy in the visible spectrum (0.4–0.7 µm); this material clearly will keep a component cooler than a nonpainted one.However, a lot of research has been performed since the 1990s to develop cool white materials that reflect solar radiation in both the visible and the infrared spectrum (0.4–2.5 µm) (Fig. 4.1).

Absorption / reflection of sunlight
Overall, Earth reflects about 29% of the incoming solar radiation, and therefore, we say the Earth''s average albedo is 0.29.
