Very new and going completely off grid.

Say g'day and tell us a little bit about yourself if you wish. If you have a wind or solar power system, big or small; flaunt its specs here!

Very new and going completely off grid.

Postby Bman » Wed Feb 03, 2016 8:56 pm

Hi, I have just purchased a property in SA that is not connected to the grid and we have been quoted $100,000 to connect. So as you can imagine, we are going solar/wind.
We have about a year to research and find out our needs before we move. We are currently in NW QLD so using a lot of power on air conditioning, but that should reduce significantly once we move.
Its just my wife and I, no kids, couple of dogs.
We plan to have gas hot water and a gas stove.
Possibly a bore with a grunfos solar powered submersible and all the normal house hold electrical items.
House has a very steep (old church) pitched roof (tin) facing east west, so probably have the panels mounted on a frame on the ground.
I will be doing a lot of reading on here for the next little while and see if I can't find some useful info.
Cheers
Brian

Hi Brian,

You're on an adventure!

As a couple of thoughts for you to consider:

- SA has less winter sun than QLD. It may be worthwhile checking the average solar hours over winter for that area before you size your system. Melbourne has about 2 peak solar hours on average for about a month either side of the winter solstice (that is because the sun is lower in the sky). What that means is that you can reliably expect about 2 hours on average output from your PV panels each day during that time of year. Hope that makes sense. But still with those connection fees (I hear you), you have a lot of fat and panels are relatively cheap. Plus SA has some very meaty power bills.

- Do you have a wood lot? Gas delivered to rural areas is expensive. Seriously. And getting more so with each year. Solar hot water works very well and a couple of panels would be a very good idea. They'll probably generate hot water for 10 months of the year.

- Is it very windy at your SA location? Like the sort of wind that pushes you backwards and is constant not gusty - eg. Near the coast or on a hill top?

Cheers

Hmm, I installed an SPS system for a client that had that sort of cost to connect, builders have been using the system to build the house, system is in the shed about 60m from where the house site is.

Worth considering when looking at how when and why.

Thanks for the welcome guys.

Chris, we will be about 2-3km from Mount Millar wind farm- which has 35 turbines, so yes, it is windy.
We hope to get wind power as well. There was a small solar system and wind generator but when the previous owner left, he took the panels and then the batteries got stolen and the turbine throw 2 blades in a storm. We will start from scratch.
Nothing is set in stone yet as far as hot water but there is already a instant hot water service there.

Gordon, I did get told by one installer that our east/west roof would not be a problem....I don't know enough yet to form an opinion. But your thread makes a lot of sense.
