I don't believe in sacrificing either after roughing it for 20 years. That doesn't mean I can't save power with LEDs, lower power TV, fans, etc. The batteries will have shallower cycles normally and last longer in the not so wonderful times.
So I'm covering the roof and filling the battery bay. I'll make the panels tiltable if I have to but I hope to avoid it. I think I'd rather put out a portable than climb the roof.
With as much solar as you have planned you will find out as I have that it will act like a micro generator. We don't have any huge loads over night so the batteries hit float early and stay there unless we run a big load. Those are short so what isn't covered by the solar is replaced quickly. My system was designed to be able to run a small air conditioner directly and have the batteries stay in float.
I too have done the cardboard thing, have the panels and controller. Am still working out the batteries and wiring but hope to mount it all soon.
