Solar Illuminace vs Panel Output
How does solar illuminace effect panel output? From yesterdays observation at noonish: 750W, poly, flat, 100F ambient, Vmp=91.7V, Imp=8.18 Logged Varray=75V, Iarray=8.5A, Controller out=605W ...

here we ago again .. beat me too it.. its the HEAT reducing voltage
the HEAT reduces the output power , and from my observation with the panels i removed and tested, its the voltage that takes the greatest hit
and with MPPT lost voltage means Lost Conversion amps/watts
example uni-solar listed VOC 23v ISC 2.94 amps
hot ambient temp 100F VOC 20.49v ISC 2.91 amps
same panel tested dead-on with ratings when cool
solar radiance can be the same two days in a row, but if one day was an ocean breeze and the next was a HOT Santa Ana wind, the hot day is going to have a lower output
