Daily supply chargeThe fixed ‘supply’ or ‘service to property’ charge on your bill, what you pay just to stay connected, separate from usage. Usually about $1.00-$1.20/day in QLD. We subtract it so only real energy use is counted.: $ / day

From your bill, the fixed daily charge (typically ~$1.00-$1.20/day in QLD). We subtract it so only your energy use is converted to kWh.

ExtrasTick anything that adds big load. A pool or EV uses a lot of extra power each year, raising your usage estimate and the battery size you’d need. bump battery size + kWh estimate

🏊 Pool

🚗 EV

System SizeThe solar array size in kilowatts, auto-matched to your home size and extras so you can run mostly off-grid. You can override the size and price under “Adjust the details”.

Auto-matched to your Home Size + Extras so you run fully off-grid. See Adjust the details below for the exact size and to change the price.

Projection HorizonHow many years to project savings over. A battery often only pays off over a longer period, so longer horizons give a fuller picture. Long horizons include an inverter replacement near year 13.

How many years to project your savings over. Long horizons include inverter replacement at year 13 and battery degradation.

Tariff Rise AssumptionHow much you expect grid electricity prices to rise each year. QLD prices have risen about 4%/year on average. A higher rate makes solar more valuable over time.

QLD averaged ~4%/yr over the last decade. Some years run hotter.

The 10/15-year total is the sum of all your money out over that period. After the system pays for itself (see "Payback" stat), your Year 8 monthly drops to just residual grid + supply, essentially near-zero for a right-sized battery. Estimate

⚠️ ESTIMATE ONLY, NOT A QUOTE. All figures on this page are indicative estimates based on Queensland AER Default Market Offer rates ($0.30/kWh), SEQ peak sun hours (5.2 hrs/day), the tariff rise you selected, and the pricing assumptions shown above. They include inverter replacement at year 13 (~$2,500) and battery degradation (3%/yr) for long horizons. Carbon offset uses the NEM grid emissions factor (~0.79 kg CO₂/kWh).
