 The Woracle is back! Warwick Johnston from Sunwiz joins us to unpack the battery frenzy kicked off by the Cheaper Home Batteries Program. We chat install rates, shifting system sizes, South Australia’s storage dominance—and yes, there’s still room for spa jokes, good merch, and questionable fashion choices. 

Just Another Solar Podcast is hosted by Luke Beattie, Karl Jensen, Nigel Morris and Jess MacPherson. It's a casual conversation that shouldn't be taken as business, financial or legal advice.
