ENnon-uniformity 
(Unit: dimensionless, usually expressed as a percentage, %)

uniformity of solar simulator irradiance on the PV module during a test

NOTE 1 Non-uniformity is calculated from the difference in maximum irradiance minus the minimum irradiance measured over the test area, divided by the sum of the maximum irradiance and the minimum irradiance

NOTE 2 The area scanned to find the minimum and maximum irradiance may be the solar simulator test plane, or it may be the module footprint
