Made the cover! (kind of...) |
What size is the house? 156.5 sqm
How long did the house build take? 6 months
What did the house cost? $360,000
Off grid and electrical systems: $42,000
Plumbing: $60,000
Waste water system: $14,000
Overspend: $16,000
How much power does the off-grid system generate? 4.5 kW hours per day
How does it work?
Our roof-mounted panels convert sunlight into an electrical current which is stored in a bank of 12 deep cycle batteries. The current is converted from DC to AC for our use.
How long will the batteries last? Up to ten years.
What happens on cloudy days?
Although the panels will still generate a little power, we can draw on the stored energy in the batteries. Once this has been used our generator can replenish them.
Where does the house water come from?
It is channelled from the roof into two 22,500 litre concrete water tanks. This is pumped back to a header tank in the house, creating a mains pressure system.
How is the water heated?
By a bank of 24 solar tubes in the summer and by a wetback system connected to our woodburner in the winter. Two radiators will also be run with the excess hot water.

I could have taken a picture like this - if I was a photographer. Note the 'gang plank' leading to our living room - this will remain until we are able to timber the deck. |
