looks like you lucked out big time with the roof slope and orientation. nice when things work that way..
"I had also considered a battery monitor, but wasn't sure how necessary it was."
brian, i suggested the monitor because i am sold on the idea of seeing exactly whats happening to every piece of equipment and every variable in the changes that occur throughout the charge and discharge cycles, as the clouds roll by and the temperature changes, as the loads are switched on and off. you can get a real feel for whats occurring and why. this is in itself the most excellent tutor i have encountered while playing with all this renewable equipment. chances are that you will never outgrow this monitor and my hat goes off to anyone who can. also if you trade that $112 controller for the $165 mppt version you are giving up that limited display info from the go power pwm unit..and we all like to look at some pretty display.
some thoughts on a battery choice..now this is my opinion only so take it as such. those expensive agms are super choices..but, may i suggest that you start out with an el cheapo marine deep cycle "hybrid" battery as a disposable learning tool? at fifty bucks for a group 27 battery you can't go wrong. and if we kill it within six months i bet we get more than a fifty dollar education from the experience. i know of people that can kill a battery in six weeks! i also know of folks that can make them last for ten years! experience and knowledge will make you one of the folks in the latter group.
also with an inverter choice..thats alotta clams for a dinky little micro inverter. i would be tempted to go the el cheapo route there as well. something like a $40 throwaway 400watt modified sine wave unit. the thinking here is you will most likely grow out of that 200ish watt pure sine wave inverter and 100ah battery bank very quickly when you see what you have done and what you are capable of.
on that note- i would strongly reccommend one of the classes there in hudson ma. you are a candidate for that pv 302 class imho. (jumping ahead of those first two courses)
http://workshops.altenergystore.com/PV-302-Intermediate-Photovoltaic-Design-and-Installation-Sat-Feb-28-Mon-Mar-2/e57/ if you look into this class, double check with the instructor for a waiver to take the advanced class without the basics classes. (looks like you have all that covered)
