No more dinosaur solar sales, no salesman at your door. I'll give you a straight answer using real Western Australia rebates. Free, takes about a minute.
Check My Joondalup Home, FreeTypical 6.6kW solar + 10kWh battery, on a $400-$600 quarterly bill.
Ballpark for that one setup. Run the actual check and I'll work out your real numbers.
Four real households, run through the same calculator this site uses for an individual report. Panels only, no battery, clean roof, someone home some of the time. Prices are after every rebate that applies in Western Australia.
| Household uses | Their quarterly bill | System | After rebates | Saves a year | Pays for itself |
|---|---|---|---|---|---|
| 10 kWh | $373 | 5–6.6kW solar | $5,270 to $7,300 | $430–$640 | 10+ years |
| 15 kWh | $510 | 6.6kW solar | $6,050 to $8,050 | $590–$880 | 8–10+ years |
| 22 kWh | $701 | 10–13kW solar | $7,800 to $12,800 | $910–$1,360 | 7–10+ years |
| 30 kWh | $919 | 10–13kW solar | $7,800 to $12,800 | $1,130–$1,690 | 6–9 years |
The bill column is what that household actually pays in Western Australia at 30c a unit, which is why the same house has a different bill in every state. Savings depend on how much of the generation gets used on site rather than exported, and at 2c a unit for exports that is the number that decides the answer. A household out all day saves less than the figures above; one home most days saves more. Every figure is produced by the calculator, not written down, so it moves when the published rates move.
Every figure in these comes from the same calculator, using Western Australia rates and rebates.
Applied automatically by your installer. Around $1500 on a standard 6.6kW system in 2026.
Synergy customers get up to $1,300 off a battery, Horizon Power (regional) customers get up to $3,800 off. No panel rebate, but the DEBS scheme pays you for what you export.
Around $2700 off a 10kWh battery, same as everywhere in Western Australia. Needs solar panels to qualify.
