What do you typically get out of a 300 watt panel for production when you
are grid tied? I know in theory (STC) it is a 300 watt module but we
rarely if ever (except in very cold weather)see near that for an output. I
use (as a general, 77 degrees F) design parameter, 77% for overall power
production output output. I'm sure you would get a little clipping, but I
guess a significant amount would depend on a number of variables on the
site, time of the year, weather conditions, etc.
