VERY High elevation 10,000'+ , with high wind & very low temps. Not normal
installation definitely a "Special" situation. I agree in 95% of installations
1.56 is an excessive.

The logic of this rule for calculating PV amperage seems a little off to me. -
It is a calculation that is set in stone as a bedrock truth of the solar
industry. (1.25 X 1.25 = 1.56).
The multiplier of 1.25 for a continuous load is relevant for sure. To multiply
again by another 1.25 seems excessive.
Although it is certainly true that modules put out considerably more power when
it is cold out, in my experience that is almost all due to the increase in
voltage. The amperage goes up a little, but no where near 25%.
Just because I haven't seen it doesn't mean it can't happen. Are there
circumstances where the amperage of a PV module can go up by 25%?
Thanks,
Drake
