With Ergon feed-in tariffs low and storm-season blackouts a fact of life, here's the honest battery payback maths for North Queensland.
The payback maths has changed (and it's not what your mate told you in 2019)
Let's be straight with you, because plenty of solar salespeople won't be. A few years back the case for a battery was thin, because Ergon Energy was paying a decent feed-in tariff for every kilowatt you exported. Why store power when the grid paid you handsomely to send it back? That world is gone. Feed-in rates have dropped right off, so the spare solar you push to the grid in the middle of the day is now worth very little. That single change has flipped the whole equation.
Here's the bit that actually matters. The value of a battery today isn't about export at all, it's about self-consumption. Every unit you store during the day and use yourself at night is a unit you don't buy back from Ergon at full retail price. In North Queensland that's a big deal, because our evening peak, the aircon cranking after a 34-degree day, the pool pump, the kids home from school, lands exactly when your panels have clocked off. A well-sized solar battery storage system shifts that cheap daytime energy into your most expensive hours. With a current rebate available under the federal Cheaper Home Batteries Program, the payback period has shortened considerably, though we'll always confirm your eligibility in writing before you commit a cent.
Blackout resilience: the part the spreadsheet can't price
Run the numbers all you like, but anyone who's lived through a Townsville wet season knows there's a value that doesn't show up on a payback calculator. When the storms roll in off the Coral Sea and the grid goes down, a standard solar system shuts off too, for safety reasons, so a power cut leaves you sitting in the dark with a roof full of panels doing nothing. A battery with proper backup capability keeps your essentials running, the fridge, the fans, the wifi, the phone chargers, sometimes the whole house.
For a lot of NQ families, that's the real reason they pull the trigger, and we get it. If you're on the city fringe or somewhere the lines take a while to get restored after a big blow, blackout cover is worth real money in food not spoiled and nights not sweated through. How much backup you get depends on the kit. A Tesla Powerwall handles seamless backup nicely, a FranklinWH whole-home battery is built to carry larger loads, and a Sigenergy battery gives you a modular, scalable option if you want to add capacity later. We'll match the system to how you actually live, not to whatever's sitting in a warehouse.
So who does it actually stack up for?
Honest answer: a battery isn't right for everyone yet, and we'll tell you straight if it isn't right for you. If you're a low user who's out all day, barely touch power in the evening, and you've already got a solid solar array exporting happily, your money might be better spent elsewhere. The households where batteries genuinely shine are the high evening users, big families, people working from home, anyone running aircon hard through our long hot months and copping a hefty Ergon bill every quarter for the privilege.
If that sounds like you, the smartest first step is getting your solar power system sized and your usage pattern understood properly, because a battery bolted onto an undersized or poorly configured setup just disappoints. The right hybrid setup, often built around a Goodwe hybrid inverter, makes adding storage now or down the track straightforward. We're locally owned, SAA-accredited and fully licensed, and Jason or one of the team is happy to come out, look at your actual bills and roof, and give you the real numbers for your place, no pressure and no fluff.
