Supplemental solar power, anyone have info?

If you are running solar on the same circuits as your utility for your fans, etc., then you need to get a grid tie system, which automatically offsets your bill.
Otherwise you have to run separate circuits and have a way to switch it.
A grid tie system is panels and an inverter. Simple. The inverter is made to add power to the grid to reduce your bill.
Off grid adds batteries and a charge controller. The inverter may not be rated to feed power to the grid.
Combining them together needs specific inverters made to do that and a little more hardware. These will switch to battery power when the utility goes down.
Good information from Stitch up there.

Like Stitch stated, the inverter and charge controller is the heart of your system. I have some experience with the Outback system, and the damn thing is solid. I also use Optima batteries, and a propane generator, which the Outback can start if it sees the charge starting to drop. This it the type of system we use at repeater sites.

Yep, in order to run off Batteries and Grid power independent of one another you would need to some extensive wiring of your home. Your only real option is to go grid tied with a system big enough to run the home.
Out here we don't even have the option for grid power ( unless I want to cough up $25,000. to the power co. ) We run our entire ranch on 1500w Solar (soon to be 2500w) and a 12K generator that charges the batteries if they get too low.
