WebMar 5, 2024 · How much light is reflected from a solar panel? The amount of light that is reflected from a solar panel is relatively low. Generally, when the angle of incidence of the solar energy is 90°, the absorptivity of the solar panel is around 90%, meaning that only 10% of sunlight is reflected off.
