I'm not sure what you're going to get out of this thread. Solar needs and the systems designed to meet those needs in the current context differ greatly. You have people on here with everything from small single batteries & portable panels up to systems that can run high-draw appliances like clothes dryers & AC. That's not to mention the cost diff based on component selection, component source/prices, etc.
For what it's worth, for 800AH of AGM storage (4 x 6v), a 1200W inverter charger, 2 MPPT controllers, 1200W of panels, 2 parallel-capable inverter generators, & assorted wiring, boxes, & hardware, we have ~$8000 estimated, assuming pretty much top-of-the-line gear @ retail prices. Have yet to see what that works out to in real life where we hopefully won't be paying top dollar. The batteries alone are about 1/3 of the total. I consider the generators part of the total system, but if I wanted to divorce them from the 'solar' price that would be ~$1200 less.
