No electric bill for those months (and July as well).
Am really looking at...

Pinball, speaking of rails, have you looked at the "rail less" roof attachments for PV panels? I have the same kind of metal ag panel roof you have. Can't tell if you have anything underneath, but...

PV guys - got a couple questions. I am just itching to get my self install 15 kW system up, but am doing my homework, carefully.
Will go with Enphase - for a lot of reasons not relevant here. ...

Rob,
I agree that low frequency AC and DC follow the same IR losses. I am comparing something like a "Sunnyboy" (centrally located string inverter), located many feet from the panels where you...

Pinball,
The 30% renewable energy tax credit expires on Dec 31 of 2016, not January 1, 2016. You are correct, that it must be fully permitted and in operation by the expiration date.

Pinnball, you wrote that "The M250 can have 16 modules on a branch circuit and that goes to a 20 amp breaker."
However, reading the Enphase material they state that only 14 M250 modules should be...

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...

Pinball and Vern,
I take it the newer Enphase 250 is better than the older 215 model. It appears that the 250 model offers free monitoring and no ground electrode conductor (GEC) must save $ as...

Pinball,
Great that you are using a performance factor of 86% as I figured in 77% (from PVWatts)in my estimates. How do you verify the 86%?
Thanks for the info on individual panel monitoring. ...

Is this a fee for service or something else?
Lastly, I am wondering how...
