David,

How room is there on your roof? In my perspective, this determines what you choose.

For example, if you have lots of roof space, then go with older panels. If you have only space for say 20 panels, then go with the new higher efficiency.

More panels, means more microinverters and racking. So set up a spreadsheet that compares and contrasts the two situations.

Does this help?
