If solar were free, but we still needed to pay for battery storage, how would it then compare in cost to fuel-based alternatives (fossil fuel, nuclear etc)?

People use way too much power for battery storage to be viable. The average household consumes 28.9kwh in a day (in 2017), which is way more than rooftop solar can provide.

Maybe when we have smaller houses and don't have a bajillion devices plugged in all the time.

Once solar generating costs are further reduced, there needs to be improved effort on improving local infrastructure (within a single residence). Getting rid of DC-AC-DC conversion would be a huge improvement. If we standardize on a DC system (48v?) then household devices can be more efficient without the conversions.
