Friday solar panel shopping

I'm going a very similar route to your setup, albeit using 100 watt panels. Started out with the trimetric, SC2030 and 4 flat mount panels, quickly added a fifth, then come fall added number 6 prior to a trip to the Washington state coast in October. I have 4 additional panels out in the garage, and will install them this spring splitting them into two separate banks of 500 watts, each controlled by a separate controller. Would have installed them prior to the snow starting to fly, but just ran out of good weather days when other things didn't take priority.

Let us know how things work out when you get the new panels and controller installed.
