Update--
Did a little more poking around last night, and OMG, things just keep getting easier and better.... That is NOT my usual luck.
* After getting the panels on the roof, I realized I can fit 800w instead of my originally planned 600w. The panels are still on sale, ordered 2 more.
* I just scored a helluva deal on a mppt controller direct from Sandy @Grape Solar - a scratch-n-ding. The only catch - it's a 45a which I will be over-paneling. It will max out @45a charge even though mathematically on a "perfect" day I could hit 60a. "Perfect" days seldom ever occur here in the PNW, so I'll have the extra panels for our more "normal" days. Morning Star controllers can handle almost double over-paneling, but this is a Grape Solar controller. I'm waiting to hear back on it's over-panel limit. Worst case I disconnect two on a perfect day.
* I called and talked to Brad@Eagle Cap because I couldn't find where the solar pre-wiring terminated. Found it last night thanx to him, and it's a nice stout 10ga wire, more than enough for the 10a I'll be passing from the panels into the controller.
So right now, six panels are here, wiring has been located, controller and 2 more panels are coming by Friday. Next will be to check each panel on the next sunny day before I screw them in and commit.
