My panels are 320W Silfab.(max power 32.88V x 9.74A, ISC 10.32A) they are installed full south at 20degree pitch in north California.
In the best spring summer days they will reach 300 watts (10A x 30 Volts.
Right now on the best days they only reach 230Watts (7.4 A x 31 Volts) or 71% of ISC

I will add for the anecdote, that during cloud edge effect (bright sunny days with passing clouds when the sun crosses the edge of the cloud), I have seen these panel reach 340Watts (30 V x 11.33A) or 110% of ISC

That's why, if you want information that means anything, you don't measure stuff on anything other than clear days.
