If the module dimensions are scaled up or down in the PAN file, this changes the collector/aperture area, so the calculated energy output scales accordingly. A larger area produces more energy; a smaller one produces less, assuming the same efficiency and operating conditions.
This is different from the collector band width, which is mainly a geometric or layout parameter used to describe how collectors are grouped or spaced in the model. Band width does not change the physical size or performance of an individual collector; it only affects how collectors are arranged or aggregated.
In short: @royal
Scaling PAN dimensions → changes active area → directly affects energy yield
Collector band width → affects layout/representation, not single-collector energy
