Designing with bifacial modules

[ggunn]

That appears to match power class 485. The corresponding BSTC column is 530.5

So they are not following the NEC to sum both sides, by not using BSTC, much less Max values without American Equipment Nameplate Standards.

BSTC w/ Wayn’s Max estimate +5W in post #10 is near ~535 per module.

1,628 modules = 870.98kW

The 1.25 multiplier should be for continuous use, not for Data Sheet errors.

The 1.25 factors (when to use them and what they apply to) confuse many new designers. Don't even get me started about 1.56 (hint: never).
