Overview
Why Brisbane Solar Just Got More Important
From 1 July 2026, retailers across South East Queensland are required to offer households three hours of free midday electricity through the new Solar Sharer Offer. On the surface that sounds like good news. In practice it’s the Energex network telling Brisbane solar owners exactly what their daytime exports are now worth: nothing.
The homeowners winning from 2026 onwards are the ones who stop selling their solar back to retailers and start storing it for their own evening use. That’s how a Brisbane home goes from a $1,200 quarterly bill to one paid almost entirely from the roof. Every Brisbane household has the same opportunity — and the same exposure if they don’t act.
Paying Full Retail
$4,800 per year
Per year to Energex — the cost of an undersized or template system on the Energex network.
The SEG Approach
$0–$200 per year
SEG customers average. That’s $4,600+ back in your pocket every year — on a system sized to YOUR Brisbane home, not a national template.

Energex & South East Queensland Tariffs
Brisbane homes are served by the Energex distribution network, which covers all of South East Queensland. SEQ households pay standard residential tariff rates with Time of Use (TOU) options available — so the time of day you draw from the grid affects what you pay per unit. A correctly sized solar-and-battery system maximises self-consumption during peak generation hours and stores energy for evening use, reducing the grid draw that attracts the highest per-unit cost.

Brisbane Solar Questions Answered
For a Brisbane home running ducted air conditioning, a pool, and paying $1,000–$1,200 a quarter, a correctly sized solar and battery system typically brings the quarterly bill to $0–$200 — and many SEG customers hit $0. That is $4,600+ back in your pocket every year. The key is correct system sizing: a standard 6.6kW package was designed for a $400 bill and will not touch yours.
For a typical Brisbane 3–4 bedroom home consuming 22–28kWh/day, a 10–13kW solar system with a 10–13kWh battery gives strong coverage. We analyse your actual Energex bills — usage patterns, peak times, and quarterly totals — before sizing your system. No template, no guessing.
Energex offers time-of-use tariff structures in South East Queensland where peak periods (typically 4pm–9pm) attract higher rates. A battery charged during solar production and discharged during these peak windows can significantly reduce your most expensive grid draw. We factor your current tariff type into the system design.
Brisbane averages 5.2–5.5 peak sun hours per day, with reliable year-round production. Even during the wet season, solar generation remains strong. Occasional overcast days are offset by excellent summer production months, and a well-sized system accounts for seasonal variation in its annual estimates.
Most Brisbane residential solar installations do not require development approval (DA) under standard zoning. Heritage-listed properties or those in specific overlay zones may have different requirements. We check planning conditions for your address as part of the design process before we recommend anything.
Payback periods vary by system size, consumption, and tariff structure, but typical Brisbane installations achieve payback in 5–7 years. With $0 upfront financing available for qualified homeowners, many customers are cash-flow positive from month one — savings exceed repayments before a single extra dollar leaves their pocket.
