Just for curiosity I looked at the link on the prev post.

You are pretty much under clouds in July there, eh? Only about 3 kW-hr per day available for a 2 by 3 meter array of solar cells, $1 at your rates, right when you need heat!

so maybe solar is not a good deal in Perth due to overcast skies when you need the power for gshp ?

In January, you will get about $5 worth of power a day from a 2x3 meter array.

Yearly average solar power of maybe close to $1000 though.
A 2x3 meter array PEAK power rating would be about 1.2 kW, Maybe $1500 DIY installed - pretty good payback due to high rates there!

Kinda like parts of Germany, where power rates are close to 40 cent kw-hr, and nearly everybody has some solar or wind.

Does AU have solar subsidies or tax credits? Look into it !
