I see you have 215 Watt panels and I'm wondering about what kind of power output you get (under idea conditions).
It just seems odd to use a 215W panel with a 190W inverter.?.
But, I don't have any hands-on experience with PV yet.
I've been day-dreaming of using the 190W Enphase inverters,
but with panels that have 190W peak output or less.
And, it seems like the 175W panels are in a much lower price range these days..
I'm thinking of starting off with 1 or 2 panels on a simple pole mount (old dish mount) as a feasibility study.
If it worked out, I would install a much bigger post and more panels.
(Using InPhase inverters).
I think the shadows in my backyard will be at their longest on the 21st.
I've been studying them every day, and I found there is one pretty good spot for a PV array, just south of the old TVRO dish.
