We have grid connected as well as a stand alone photovoltaic system and evacuated tube solar hot water system.The house is brick veneer and 35 years old on 600m2 of land.
We have over 10,000 litres of water storage and a dozen or so fruit trees. We have also made various styles of solar cookers, stored heat cooker, pot in pot cooler, rocket stove etc. We have found that while it is easy to plug stuff in to a 240V system, or to buy your veggies, to make and do stuff for yourself you need to know stuff and access to expertise helps.
We have a permaculture garden with elements in the back and front yard including chook tractor, greenhouse, self watering containers, wicking beds, banana circle, herb spiral, worm tower and worm bath, insectary beds and a strawberry tower.
During 2015/2016 we have added a constructed wetland to treat our laundry greywater and moved the banana circle to the back to make use of greywater plumbed directly from the spa bath. We have installed super efficient irrigation to reduce water usage in all 14 veggie patches and have install Nickel Iron batteries, more solar panels and an inverter /charger to go off grid.
We have a street library and seat installed in the front of the house to encourage passers by to pick up and trade books with us.
