Indeed, the coal lobby in Oz has various groups held well and truly by the gonads and despite the SA Tesla battery success story is unlikely to loosen their grip anytime soon.
After years of trying to reduce our power bills I finally bit the bullet and installed a Tesla PowerwallII being fed by a 8.6Kw PV array on our roof.
It’s a sunny day...The 14Kw battery is 40% charged as I write (9.20am) it will be fully charged by noon, with all our daily power needs taken care of and about 6Kw going back to the grid. ROI about 4 years...maybe less if they keep jacking up the cost of energy.
Best decision I’ve made in a while...which I am sure the SA government is also realising with their uber big Tesla battery.
