Off grid costs

So, let’s get down to the nitty gritty.  Are you sitting comfortably?

The complete system – energy audit, professional design of system, all labour and equipment was $60,090 (in 2012).  By far the biggest expense was the battery bank – around $35k just for those.  We were thankfully able to access a government rebate of $7000.

So, why did we go off-grid?  Because we’re in a rural area (on 17 acres and over a kilometre from the nearest power pole) the quote to a) install a power pole near our front gate b) dig across the road, albeit a dirt one with very little traffic and c) dig a 500m trench & install conduit & cabling came in around $35,000 anyway.  Plus 15-20 years of power bills.

While we might save money in the short term, eventually the battery bank will need replacing and the final outcome of off-grid vs grid-connect is a little hard to evaluate.  However it pans out, I wouldn’t have it any other way!

While this really isn’t a viable option for many, a small storage battery might work for some.  In the meantime, I’m just hoping for an ongoing price reduction for batteries!
