Maybe, but I doubt it.
For me, I'd do a amperage check. Then I'd hook it up to something to see how it worked. I have a small SCC that is hooked to 6 USB charging points and I could get data.
I see some differences in panel outputs. I think its got to do with the temperature coefficient of a panel. THe higher the temp, the lower the voltage. I've measured my roof flat panels at 134° F and my Flexible panels at 154° F, so using the ambient temp may lead to results being off.
Rich solar probably includes ambient temp coefficient with some negative number.
I think its probably good. You can cool it down by leaving it in the shade or bringing indoors or waiting to morning and try again.
