For years, Queensland solar owners could be lazy in the nicest way. Export your spare power, collect a decent feed-in credit, done. That era is over. From 1 July 2026 the regional feed-in tariff fell to 6.006 cents per kilowatt hour, down about 29 percent in one hit.
Here is the reframe that matters: your solar did not get less valuable. Your exports did. Power used inside your home still saves you the full grid rate, several times that 6 cents. The game now is simple to say and easy to do: use more of what you make.
We are G-Solar & Electrical, based at 32 Magazine Street in Stratford, and this is the playbook we walk Cairns customers through.
Quick Answer
- Exported solar now earns about 6 cents. Self-used solar saves several times more
- Move your big flexible loads into daylight: hot water, pool pump, washing, dishwasher, EV
- Timers and delay-start buttons do most of the work for free
- Heating water in daylight hours is the single biggest easy win for most homes
- A battery is the endgame: it time-shifts your solar into the evening automatically
- Same roof, same weather, and a much smaller bill after one week of new habits
Step 1: Know Your Numbers
You cannot manage what you cannot see. Your inverter’s monitoring app shows when your system generates and, on most setups, when your home consumes. Ten minutes in the app tells you your daily story: the generation curve rising through the morning, peaking near midday, fading through the afternoon, and your usage sitting on top of it.
Every hour where usage runs below generation, you are exporting for 6 cents. Every hour after dark, you are buying at full price. The whole playbook is about closing those two gaps. If you run a Fronius system, our Solar.web guide shows exactly where to look, and our Cairns bill guide helps you translate hours into dollars.
Step 2: Move the Movable Loads
Most homes have a handful of hungry appliances that do not care what time they run. Every one you shift into daylight swaps a 6 cent export for a full-price saving.
- Hot water. The big one. An electric storage tank is basically a battery made of water, and it does not mind heating at noon instead of midnight. A simple timer on the hot water circuit points that whole load at your solar. This one change is so valuable we wrote a full guide to heating water with solar.
- Pool pump. Hours of steady draw, completely flexible. Run it through the middle of the day, every day, on its own timer.
- Washing machine and dishwasher. Both have delay-start buttons almost nobody presses. Load them in the evening, set them to run mid-morning. Free money, zero lifestyle change.
- EV charging. The biggest movable load of all if you have one. Daytime charging from your own roof is the cheapest driving in Australia; our EV plus solar guide runs the numbers.
- Aircon pre-cooling. Cool the house harder in the late afternoon while the panels are still producing, then ease the load after dark. In an FNQ summer this one habit noticeably trims the evening peak. Full detail in running aircon on solar.
None of this requires new hardware beyond a couple of cheap timers. One week of new habits, then it runs itself.
Step 3: Spread, Don’t Stack
Habit two is about shape. Running the dishwasher, washing machine and pool pump all at 11 am stacks your loads into a spike that can overshoot your generation and pull from the grid anyway. Stagger them: one at 9, one at 11, one at 1. Your generation curve is a long plateau in the middle of a Cairns day, and about 5 peak sun hours is a lot of plateau to fill.
The same thinking helps on the generation side. If you are designing a system now, panels split across east and west faces produce across more of the day rather than one midday spike. That pairs beautifully with spread-out loads, and it also plays nicely with the 5 kVA export cap most Ergon-area homes sit under. See our guides to panel direction and tilt and export limits in QLD.
Step 4: The Battery Endgame
Habits close a lot of the gap. A battery closes almost all of it, automatically, with no timers and no thinking. Midday surplus goes into storage instead of 6 cent exports, then powers your evening at grid rates you no longer pay.
The maths on this improved twice in twelve months: the feed-in cut made stored power more valuable relative to exports, and the federal Cheaper Home Batteries Program takes roughly 30 percent off installed cost, tiered by size since 1 May 2026. For Cairns homes there is a third, very local benefit: backup through cyclone season blackouts, covered in our guide to batteries in cyclone season.
Start with what size battery you need, see what a battery costs in FNQ, and compare the batteries we install. Retrofitting onto an existing system is routine; our battery retrofit guide explains the paths.
What This Looks Like in Practice
A rough before-and-after for a typical Cairns solar home, same system, same weather:
| Before: export-heavy | After: self-use habits | After: habits plus battery | |
|---|---|---|---|
| Midday surplus | Exported at 6c | Runs hot water, pool, washing | Charges the battery |
| Evening power | Bought at full rate | Reduced by pre-cooling | Supplied by the battery |
| Blackout in the wet season | Lights out | Lights out | Essentials keep running |
| Effort | None | Two timers, delay buttons | None, it is automatic |
If your bills have crept up since July even with panels on the roof, this table is usually why. The system did not change. The value of exporting did. And if output itself seems low, rule out hardware first with our troubleshooting guide or book a solar health check.
Frequently Asked Questions
Why did my solar feed-in credit drop in 2026?
The regulated regional Queensland feed-in tariff fell to 6.006 cents per kilowatt hour from 1 July 2026, down about 29 percent. Smaller credits for the same exports is the direct result.
Is solar still worth it with a 6 cent feed-in tariff?
Yes, because feed-in credits were never the main value. Solar you use yourself still offsets the full grid rate. Our full breakdown is in is solar worth it in Queensland.
What is the easiest way to use more of my own solar?
Put your electric hot water on a timer so it heats during the day, and use the delay-start buttons on your dishwasher and washing machine. Those changes cost almost nothing and shift a big slice of load into daylight.
Should I get a battery instead of changing habits?
Do the habits first since they are nearly free, then size a battery for the surplus that remains. The habits also shrink the battery you need, which lowers the price of the endgame.
Does self-consumption matter if I have a big export limit?
Yes. The export cap decides how much you are allowed to sell at 6 cents; self-consumption decides how much you avoid buying at several times that. The second number is worth more regardless of the first.
How much of my solar should I be using myself?
Export-heavy homes often self-use only around a third of their generation. With daylight-shifted loads that share rises substantially, and with a well-sized battery most generation ends up serving your own home.
Turn the Tariff Cut Into a Non-Event
We help Cairns homes rework timers, loads and system settings for the 6 cent era, and size batteries only as big as the remaining surplus justifies. Straight advice, backed by a 10 year workmanship guarantee. Call 07 4039 4914 or book a free consultation.
