Queensland does not have one universal current state cash rebate for every private household installing rooftop solar. Eligible systems can use federal solar STCs and federal battery STCs. Feed-in tariff treatment differs between competitive retailer offers in south-east Queensland and the regulated tariff applying in regional Queensland.
Targeted community housing, concession, local, retailer, or network programs may exist, but they should not be presented as a general homeowner rebate.
Federal solar STCs
Eligible Queensland rooftop solar creates STCs under the national Small-scale Renewable Energy Scheme. Most customers assign them to a registered agent for an upfront quote discount.
Certificate entitlement reflects capacity, zone, installation date, and remaining deeming period. Queensland's solar resource does not mean every roof has identical production or certificate treatment.
Confirm exact equipment, accreditation, gross price, STC value, and final price.
Federal battery discount
Eligible batteries can create STCs under the Cheaper Home Batteries Program. The calculation became tiered from 1 May 2026.
Battery eligibility, usable capacity, approved products, installation evidence, and connection to solar matter. Use the CER calculator and Australia Solar Battery Rebate Guide.
Do not rely on expired Queensland battery-program advertisements.
South-east Queensland feed-in tariffs
Customers in the Energex distribution area generally choose among competitive electricity retailer offers. Retailers set feed-in tariffs and can combine them with different usage rates, supply charges, demand tariffs, caps, and benefit periods.
Compare plans through Energy Made Easy using actual consumption and export data. The highest feed-in rate may not produce the lowest annual bill.
Check whether switching plans changes time-of-use or demand charging.
Regional Queensland feed-in tariff
The Queensland Competition Authority sets a regulated solar feed-in tariff for eligible regional customers each financial year under direction.
The 2026–27 determination applies from 1 July 2026. Use the current QCA figure and Ergon Energy Retail eligibility information rather than a prior-year rate.
Regional arrangements should not be applied to south-east market offers.
Identify network and retailer
Energex distributes electricity in south-east Queensland. Ergon Energy Network covers much of regional Queensland, while retail arrangements differ.
The network sets connection, inverter, phase, export, and technical rules. The retailer bills imports and feed-in credits.
Record both entities before evaluating a quote.
Export and connection limits
Network approval determines allowed inverter and export capacity. Conditions can depend on phase, feeder, location, system size, battery, and equipment capability.
A larger panel array may operate behind a lower export limit, but surplus beyond household use and allowed export can be curtailed.
Ask for the written connection offer and model expected annual curtailment.
Dynamic connections
Queensland networks have developed dynamic connection capabilities in some contexts. A flexible export arrangement can allow more export when capacity exists and reduce it when the local network is constrained.
Compatible equipment, communications, commissioning, and fallback settings are required. Availability is address- and network-specific.
Read Australia Dynamic Export Limits.
High solar production and heat
Queensland has strong solar resources, but high cell temperature can reduce instantaneous panel efficiency. Cyclone, wind, hail, salt, humidity, and roof conditions vary by region.
Equipment ratings, mounting, structural design, corrosion resistance, and installer experience should match the site.
Production estimates should use local weather and shade data.
Self-consumption
Feed-in tariffs are commonly below retail import prices. Running flexible loads during solar hours can provide more value than exporting and buying electricity later.
Pool pumps, hot water, cooling, laundry, and EV charging may be shifted where practical. Avoid creating waste merely to increase self-consumption.
A battery should be evaluated after low-cost load timing.
Targeted programs
Queensland may fund energy upgrades for community housing, concessions, remote communities, or defined cohorts. These programs have specific applicant and property requirements.
Use Queensland Government and scheme-administrator pages. Do not assume a targeted provider rebate is available to an ordinary owner-occupier.
Queensland quote checklist
- Federal solar STCs.
- Federal battery STCs if included.
- Energex or Ergon network area.
- South-east market or regional regulated tariff.
- Approved inverter and export limit.
- Retail usage, supply, demand, and feed-in rates.
- Roof and climate-specific design.
- Gross and final cash price.
- Accreditation, licensing, and electrical certificate.
- Current official source for every benefit.
Verify postcode-specific rules
Queensland's retail and network structure makes postcode essential. Recheck QCA, Energy Made Easy, the distribution network, retailer, CER, and Queensland Government immediately before contracting.

Keep Queensland project records
Retain the STC assignment, electrical certificate, network connection approval, export setting, meter work, retailer plan, equipment serial numbers, cyclone or structural documentation where relevant, and monitoring credentials. These records matter when changing retailer, replacing an inverter, adding a battery, making an insurance claim, or selling the property.
