Reflections from PV panels may impair observers. Studies have found that 7 W/m 2 is enough to cause an after-image lasting 4 to 12 seconds ().This represents a reflection of only 1-2% of typical solar irradiance (incoming sunlight) for a given location, which typically ranges between 800-1000 W/m 2.. A key factor of reflectance is the position of PV modules relative to the sun.
