Pinball,
You spoke of your 111% actual PV output compared to what PVWatts predicted. Was this using the performance factor of 86% vs. the default of 77%?
Secondly, what diameter (gauge) wire did you bring down from the Enphase output to your electrical panel? The smaller the wire, the greater the resistance loss, but fatter wire is more expensive. Do you have a suggestion on that trade off?
Wire is one of those things that you put in once . . . . so your thoughts on the balance of efficiency vs. cost are highly appreciated.
Vern (and others), feel free to chime in.
Steve
