My understanding is that solar panels are typically series wired
as many as 10 high -- 500VDC into inverter.

But, the individual wafers (on a panel) are probably wired in a
series-parallel configuration with a nominal 48VDC output.

To increase the ampacity from an array of such panels, I assume
simply wiring in parallel would not be as effective as installing
an MPPT controller on each and then combining to a 48VDC output?
I.e., absorbing the cost of the conversion inefficiency in return
for being able to eek a bit of extra power out of an underperforming
panel?

And, that this would be preferable to stacking them and then
down-regulating to 48VDC?
