I'm assuming that's 45 kwh/day? if so that's a lot to try and cover via solar. It's doable but you had better be rich. First step is to figure out where all of that power is going and reduce the usage. Get something like a kilowatt meter and start recording power usage on all of your 110V devices.

I'm assuming your house is all electric with that level of usage so check the temperature coming out of the hotwater tank. It can probably be turned down a lot.

AC takes a lot of power and will require a serious off grid system. If you are going to keep using it I'd recommend looking into a grid tied system sized appropriately so that during the sunny winter months you can build up a credit with the utility and then draw that down during the summer with the AC.
