Solar Batteries in Brisbane & the Gold Coast

Imagine using your own solar power after the sun goes down. A home battery stores extra solar energy during the day so you can use it in the evening, and can give backup power during an outage if your system is set up for it.

Government Incentives

Battery Rebate – Cheaper Home Batteries Program

Eligible new home batteries can receive an upfront discount through Small-scale Technology Certificates (STCs). From 1 May 2026 the discount is tiered by battery size: the full STC factor applies up to 14kWh of usable capacity, a reduced rate applies from 14 to 28kWh, and a lower rate again from 28 to 50kWh.

The discount also steps down over time and is based on the date the battery is installed, not the date you sign. Only one battery per premises is eligible. We calculate your rebate and show it on your quote, using the Clean Energy Regulator calculator.

Queensland Battery Rebate Note: Check for any active Queensland state programs when requesting your quote [VERIFY before adding any state claim].

Add a Battery to Existing Solar?

Often yes. Many existing solar systems can be paired with an AC-coupled or hybrid battery. We check your inverter model, current switchboard capacity, and network eligibility before recommending a solution.

Backup During a Blackout

Backup depends on the battery model, how it is installed, and which circuits are connected. Not every battery provides backup, and a battery may not power every heavy appliance at once. We clearly explain what your system will and will not run during an outage.

Tesla Powerwall vs Sigenergy

Both are well-known options. Tesla offers an integrated, wall-mounted unit. Sigenergy offers modular capacity and EV charger integration. The right choice depends on your usage, solar system, budget and backup needs. Ask us for a side-by-side quote.

Safety & Australian Standards

All batteries are installed by accredited electricians strictly following Australian Standards (including AS/NZS 5139 for battery installations) using products from the approved product list.

Common Questions

Frequently Asked Questions

A typical home system price depends on system size, quality of panels and inverter, roof type, and switchboard condition. All prices reflect the upfront Small-scale Technology Certificate (STC) discount. We provide a transparent, fixed written quote after assessing your property.

There is no cash payment sent to you. Eligible solar systems receive Small-scale Technology Certificates (STCs), which are applied directly as an upfront discount on your quote. The number of STCs depends on your system size, geographical zone, and installation date.

Payback depends on your energy consumption, electricity tariff, upfront net system cost, and what percentage of power you use during daylight hours. We provide a tailored payback estimate with clear documented assumptions rather than unrealistic generic claims.

Feed-in tariffs are set by individual electricity retailers (not solar installers) and change periodically. We recommend comparing retailers using the Australian Government's Energy Made Easy comparison tool to maximize your feed-in return.

Your distribution network operator (Energex in South East QLD or Ergon Energy in regional QLD) may place limits on how much surplus solar electricity can be exported to the grid (commonly 5kW per phase). We verify and factor these network limits directly into your system engineering.
