what appliances do you currently have that use electricity? Completely DC is possible but usually involves using gas/wood/propane/... for the major appliances. I highly doubt you would come close to saving any money by going 100% DC just throw a couple of extra panels on the roof to deal with any losses during the conversion.
I don't know the requirements in your area but it should be possible to get a grid tied with battery bank setup that will disconnect your house from the grid when the power goes out or the utility wants to but will leave you drawing from the batteries so the house stays running.
It's just a question of money. How many KWH a month do you currently use?
