Where pool power bills actually go
The average Brisbane pool home spends $1,540/yr running pool gear. Break it down by component and the solar opportunity is obvious — most of it is daytime load.
Pool pump
A single-speed 1.5HP pool pump running 8 hours/day costs $620–$780/yr in Brisbane on Energex tariffs. A variable-speed pump (Astralpool Viron, Davey ProMaster ECO) drops this to $180–$260.
Pool heating (gas or HP)
Gas heating a 50,000L pool to 28°C runs $1,200–$1,800/yr. Heat pump heating runs $400–$700/yr — and is the perfect daytime solar load. Solar pool heating panels (matting) on the roof cut this to near zero in summer.
Chlorinator / saltwater cell
A saltwater chlorinator draws around 200W when running, typically 8 hours daytime in summer — about $90/yr. Cheap compared to pump and heater but worth running on solar.
Pool LED lighting
Modern LED pool lights are tiny loads (40–80W) and irrelevant to the cost equation. Older incandescent and halogen pool lights can pull 400W+ — replace before sizing solar.
The 4-step pool solar strategy
How we cut a Brisbane pool home's annual power bill from $4,600+ down to under $600.
Step 1 — Size solar to the load
Pools push household consumption up by 4,000–8,000 kWh/year. We typically recommend 10kW solar for a standard family + pool, or 13.2kW for pool + ducted A/C + EV. Single-speed pumps need bigger systems than variable-speed.
Step 2 — Run pump on a timer
Variable-speed pumps should run 10am–4pm when solar output peaks. We program the pump timer to match the solar generation curve — typically 5–7 hours at low RPM. Result: pump runs almost entirely on free solar.
Step 3 — Swap gas for a heat pump
A 13–17 kW heat pump heats a 50,000L pool for $400–$700/yr on grid, or $40–$80/yr if run on solar daytime. We size solar to cover both household and heat pump load — usually 10–13.2kW.
Step 4 — Battery for evening loads (optional)
If the household runs ducted A/C in the evening on top of pool loads, a battery prevents grid imports after 6pm. Powerwall 3 or Sungrow SBH (13.5 kWh) typically gets pool+household to 95% self-sufficient.
Real example: Carindale 4-bed, 50,000L pool + heat pump
A real customer in Carindale, before and after. 13.2kW Sungrow + Powerwall 3 + heat pump + variable-speed pump.

Don't undersize for a pool home
The most common mistake: a Brisbane pool home gets a 6.6kW system because that's the "standard" quote. Pool pump + heat pump + household loads need 10–13.2kW. Going small means importing 3,000+ kWh from the grid that solar should have covered — about $1,000/yr lost.
