● When the power of PV modules under normal irradiance is the same and the colors of
PV modules in the layout are similar, the PV modules are normal.
● When the power of PV modules under normal irradiance is the same but the colors of
some PV modules are darker than those of the other PV modules in the layout, PV
modules with darker colors may be inefficient PV modules if the module surfaces are
clean and there is no shading.
