Ah, I know those framed laminates, 64W used to be a common size.

my three sets , are different wattages
the first set of 3 panels..39w each

second set 2 panels 64w each

third set 4 panels 33w each

PT and others have said never saw those sizes

but they are clearly marked

don't know why so many different power ratings
but they are all the same voltage and all play nice together
all have the same number of cells
but each set has different size cells
the cells on the 33w are smaller than the cells on the 39w which are smaller than the cells on the 64 watt

so its the increased size of the cells that determines the increased wattage
