Going to have at a block of land on Monday with the view of building an off the grid 2 bedroom unit/small house. Spent the last couple of days scratching plans on bits of paper.
Been an interesting exercise planning power, which will be solar and an oh my god genie as back up, water storage and heating of (thinking diesel at this point, options there also for house heating), Black and grey water disposal (trying to stay away from septic tanks). I will self build, timber framed and clad with horizontal colorbond. Interior will be plasterboard.
So if anyone has some thoughts, please feel free to post
cheers

bloody free campers now what permanent sites , suppose I will still have to pay shire rates
hi tony,
building laws dictate the insulation ( there will be plenty) and no white ants in Tassie, this block is in Queenstown on the wild west of Tassie
cheers

Spend lots of time on google.
This is not a brand new thing you are doing.....it has been done many times before.....learn from the success and failures of others.
I would avoid the diesel if you can. Solar is cheaper than it has ever been before. Maybe supplement that with as large a wind generator as you can afford plus evacuated tube water heating. Check out high thermal mass heat storage under the floor.
Insulation is king. Think of a number and double it. Double glazing is a minimum.
Check out desiccating toilets, but be careful to note the power consumption.
There is allmost no place in Australia where a carefully designed house, on a good alignment which takes advantage of the sun and wind in the area, cannot be comfortable to live in all the year round. There are lots of books on the subject. A little thought about the principles of natural heat flow and ventilation, and heat insulation and thermal storage will get you most of the way there after some study of the subject. Perhaps a little "out of the normal square" thinking is required but it is not rocket science.
However if you choose to put your house in a gully by the creek on a south facing aspect, then buy the genny and the diesel heater

PS dry composting toilets are a good easy option I have used and are easy to use.

HAPPINESS is a journey, not a destination.
So work like you don't need the money,
Sing like no-one is listening,
Love like you've never been hurt &
Dance like no one's watching
With 300 rain days a year, how effecient will your solar be with all that cloud cover, have the generator full of fuel
operates quite well surprisingly. I have 2 small solar lights atm and they work for a short time every night and have never failed. Certainly not as effective as other places but Tassie is really solar efficient friendly.
If you do some calculations on what you would spend on power, sewage & heating costs over 5-10 years if you were hooked up on grid here in Tassie & you will have a healthy budget for alternatives I would think. Most posts I see on the cost of solar, diesel/gas heaters & batteries etc seem to overlook the cost of household power & heating per year when they were not travelling.

Hi David
My last quarterly power bill was $1000, that's one of the reason I'm looking at off the grid
Rule of thumb for off grid.
First job.....Choose the most energy efficient appliances you can find. The cost of reducing your consumption (by buying new appliances and having the best insulation) is almost always less than generating and storing the power to feed inefficient ones.
Blaze . My power at home was 1200-1500 . I fitted 6kw solar, 5 kW inverter . Max single phase for NSW . Changed timer on hot water service to be on between 9 to 3 pm.. Do all our laundry through the day, pool pump 8am to midday. Power bill now is $450 to $550 a quarter . Next step will be solar, gas hot water . Heating and cooling is the consumption users . Lights, LED TVs use bugger all .. With tunners on fridges, freezers, HWS etc at night . So battery draw was only lights and entertainmen. 4 X 100 kW battery storage for a start . With fridges timer on for 20 min after midnight .

My little 1.5KVA solar system reduces our bill to around $200/quarter. Should have gone for 5KVA!
Perhaps my 50c/KWH feed in rebate/subsidy helps. Plus of course the State Gov. Part Pensioner discounts.
Before I retired almost 20 years ago I used to dream of a small self contained cabin in Tassie looking out over a green clothed re-entrant onto a pounding ocean beach. Well past that now at 75 with all my failing body bits.
Good luck with your adventure Blaze.

My electricity bill comes to around $80 each month, fairly large 4 bedroom home, 2 0f us at home, use air con for heating and cooling, no pool, solar hot water, don't worry too much about usage live on NSW Central Coast,
Some of those bills seem to be very high, but I suppose it matters very much, just where your home is located.
Cheers
