Build A New House

I plan to build a new house and hoped to have it fully solar powered.?
I have a large family 2 adults & 7 kids and plan to build a 250sqm brick home at Agnes Waters Central Queenland Australia. Our power bill for 3 months is around $1000 now but do run a/c 24/7 at summer. Our goverment is offering large rebates is it possible and affordable?
Take a look at your electric bill and see how many kilowatt hours (kwh) a month you buy. If you were to size the solar system based on your current use, that would be the number to use in a solar calculator http://www.altestore.com/store/calculators/on_grid_calculator/.
However, if you are having a new house built, make sure it is as energy efficient as possible to try to reduce that number a lot. Spending the money in reducing your usage is a much better use of your money. Every $1 you spend to use less is equal to $4 less in your solar system.
You say you want the house “fully solar powered”. Does that mean the electric grid is not available there and you have to be off grid with batteries for night? If so, then I would say, no, at your current usage, it is not affordable if you are going to be running your AC 24×7. If you have the electric company available, and by fully solar powered you mean you want to generate as much as you can during the day, sell any extra back to the power company, and then buy it back from them at night, then yes, depending on the incentives and the price of electricity, both buying and selling, then it may be possible if you conserve first.
Also look into solar water heating as a fabulous way to reduce your power bill and generate free hot water. http://www.altestore.com/store/Solar-Water-Heaters/Climate-freezes-Closed-Loop-Systems/Closed-Loop-Systems-for-5-People/Closed-Loop-PV-Powered-w-Tank/AET-PV-w-120-Gal-Tank-96-SqFt-Collectors/p169/
