HI all

All those 75 watt panels were really close to the same parameters.

According to one catalog, it was:  4.4 imp,  4.8isc,  17 vmp, 21 voc

From memory, they did poorly in hot weather, heavy voltage drop.

But in this case my bigger concern would be how to input data for a bunch of old used Astropower 75s. Astropower's been gone for over ten years, I think, and data isn't likely to show up on the backsheets. WINCaps doesn't account for module degradation, either.
