Solar Battery Brisbane: 7 Best Installers for 2026

A solar battery in Brisbane costs roughly $11,000 to $15,000 installed for 13.5 kWh before incentives, and the federal Cheaper Home Batteries Program takes about $3,460 to $3,640 off that if the battery is installed by 31 December 2026, as at November 2026. Queensland has no state battery rebate. This guide compares seven Brisbane battery installers that are not the picks in our other Brisbane lists, so you can build a shortlist of three quotes.

This is independent desk research from company websites, Google Maps ratings, our own directory and government program pages. We did not contact any company, request quotes, or accept payment for inclusion, apart from the featured partner marked at the top. Brisbane has no shortage of installers, so the useful question is which ones treat batteries as core work, publish what they use, and stand behind the install.

Featured partner: Renewlec

Featured partner. Renewlec is a commercial client of Solar Cobber’s publisher and is listed first for that reason. The editorial picks below it were chosen on the criteria in this guide, and none of them paid for inclusion.

It is also our pick for body corporates and multi-residential projects.

Renewlec is a Herston electrical and solar business that says it has an in-house team of accredited technicians. It also sells Solshare for body corporates, which is unusual among the sellers here.

Pros

• Handles residential, commercial and multi-complex properties, plus EV chargers and heat pumps
• Says it has an in-house team and offers a free site assessment
• 5.0 stars from roughly 58 Google reviews as at November 2026

Cons

• Names no battery or panel brands on its homepage
• No workmanship warranty term or accreditation body named, only “fully accredited”
• No prices published

Key facts. Herston office; flexible payment options mentioned on its site.

Best for strata and multi-dwelling projects. Look elsewhere if you want to see brands and warranty terms before calling.

Key facts

• As at November 2026, Queensland has no state home battery rebate, because the Battery Booster closed to applications on 8 May 2024 and has not been replaced.
• The federal Cheaper Home Batteries Program gives 6.8 small-scale technology certificates per usable kWh for batteries installed from 1 May to 31 December 2026, worth about $3,460 to $3,640 on a 13.5 kWh battery at $38 to $40 per certificate.
• From 1 January 2027 the federal Cheaper Home Batteries Program factor falls to 5.7 certificates per kWh, which cuts roughly $570 to $600 from the discount on a 13.5 kWh battery.
• Our Brisbane Powerwall guide reports a Tesla Powerwall 3 at roughly $15,000 to $17,000 installed before the federal discount in Brisbane in 2026, while our general battery cost guide puts a 13.5 kWh battery at $11,000 to $15,000.
• Google Maps showed the seven installers in this guide at 4.8 to 5.0 stars from 40 to 316 reviews each, as at November 2026, so rating alone will not separate them.
• Symons Energy is the only one of the seven Brisbane installers in this guide that publishes any price figure on its own website, as at November 2026, and those figures are for solar systems, not batteries.

Quick winners

• Featured partner: Renewlec (Herston), listed first as a commercial client of our publisher; also our pick for body corporates and multi-residential
• Best Established In-House Installer: Custom Solar Power (Acacia Ridge)
• Best Long Warranty Claim: Symons Energy (Sunnybank Hills and Sunshine Coast)
• Best for Brand Range and Off-Grid: Optimum Solar Energy (Enoggera)
• Best for Scale and Tesla Plus VPP Options: Think Renewable (Fortitude Valley)
• Best for Tesla and Premium Panels: Sunrays Power (Coopers Plains)
• Best Longest-Running Local: Local Power (West End)

Comparison table

The table summarises what each company states on its own website plus its Google Maps rating as at November 2026. “Not published” means we could not find it on the company’s site.

How the battery incentives work in Brisbane (November 2026)

Federal discount. The Cheaper Home Batteries Program, run by the Clean Energy Regulator and described by DCCEEW, is a point-of-sale discount through small-scale technology certificates (STCs). Your installer claims the certificates and takes their value off your invoice, and there is no income test and no application. The discount tapers with size: the full rate on the first 14 kWh of usable capacity, 60 per cent from 14 to 28 kWh and 15 per cent from 28 to 50 kWh. The battery must be installed with solar and, if it is grid connected, must be capable of joining a virtual power plant (VPP), though you do not have to join one.

Queensland. There is no state battery rebate. Our Queensland solar and battery rebate guide explains that the Battery Booster ended in May 2024, and that the only open state program, Supercharged Solar for Renters, covers rental solar and not batteries. Searches for a solar battery rebate QLD therefore end at the federal discount.

Energex rules. Most of Brisbane is on the Energex network. Energex publishes its basic and dynamic connection offers on its website. As at November 2026 its published tables show a single-phase basic (fixed) connection at up to 10 kVA of inverter capacity with a 5 kW export limit, and a dynamic connection with a default export floor of 1.5 kW that can rise to 10 kW when the network has spare capacity. Energex says a hybrid inverter is capped at 10 kVA on single phase under either offer. Energex blocked automated access to its pages when we checked, so we read these figures from search extracts of its pages, not the pages themselves. Confirm them on the Energex page or with your installer, and ask each installer how your design handles them.

The worked figures below use our rebate guide’s certificate factor and a $38 to $40 certificate price. They are estimates, not quotes.

Best Established In-House Installer: Custom Solar Power

Custom Solar Power is an Acacia Ridge electrical and solar business that says it puts its own installers on every job and never subcontracts. It is the strongest fit on this list for a household that wants a single accountable crew for a battery retrofit.

Pros

• Says every job uses its own installers, never subcontracted
• States it is Solar Accreditation Australia (SAA) accredited and a New Energy Tech Consumer Code approved retailer, plus Gold Master Electrician status and electrical licence EC 83233
• Roughly 5.0 stars from about 112 Google reviews as at November 2026

Cons

• Its homepage names no battery brands, so you cannot judge range or fit before booking a consult
• No workmanship warranty term and no prices are published
• Its “almost 20 years” claim sits beside structured data on its site listing a 2017 founding date, so ask which is the company’s own history

Get a quote at customsolarpower.com.au, or browse all Brisbane installers in our Queensland directory.

Key facts. Based at Overlord Place, Acacia Ridge, serving Brisbane, Logan, Ipswich, the Gold Coast, the Sunshine Coast and northern New South Wales, according to its website. It also installs EV chargers and energy automation.

Installation quality and reputation. We did not find a SolarQuotes or ProductReview.com.au listing we could confirm for Custom Solar Power in November 2026, so the Google rating is the only rating evidence here.

Pricing and value. Not published. It offers a free 15-minute review.

Best for southside and Logan households wanting in-house crews. Look elsewhere if you want published brands and prices before calling.

Best Long Warranty Claim: Symons Energy

Symons Energy says it has installed solar in Brisbane and on the Sunshine Coast since 2010 and that its accredited electricians do the work rather than hired contractors. It also publishes the most pricing detail of the seven.

Pros

• Names its battery brands: Sonnen, GoodWe, Sungrow and Sigenergy
• Says it offers a 25-year guarantee, and publishes indicative solar prices after rebate (about $6,990 for a 6.6 kW system and about $4,000 for 3 kW, as stated on its site)
• 5.0 stars from roughly 150 Google reviews as at November 2026; the company’s own site cites 157

Cons

• The 25-year “guarantee” is not labelled as workmanship, so confirm whether it covers installation, equipment or both, and who pays if a claim is made
• Battery prices are not published, only solar
• Brisbane base is in the south (Sunnybank Hills and Eight Mile Plains area), so northside lead times may be longer

Get a quote at symonsenergy.com.au, or browse all Brisbane installers in our Queensland directory.

Key facts. Queensland electrical contractor licence 71486 shown on its site, with a Sunshine Coast office at Currimundi.

Products and brands offered. Panels from Jinko, LONGi, REC, Aiko, Tindo and others; Sungrow, SMA and Fronius inverters; the batteries above. See our Sigenergy SigenStor review if that is on your quote.

Pricing and value. Solar pricing is published; battery pricing requires a quote.

Best for buyers who want brand choice and a long-running local electrician. Look elsewhere for northside crews or published battery prices.

Best for Brand Range and Off-Grid: Optimum Solar Energy

Optimum Solar Energy describes itself as a Brisbane-based, locally owned business founded in 2014 that designs, supplies and installs in-house with no subcontractors. Its site shows a wider logo set than most, including Victron and Deye, and a dedicated off-grid enquiry path.

Pros

• Says it offers a lifetime warranty on its workmanship
• Lists Solar Accreditation Australia, New Energy Tech Consumer Code and Tesla Powerwall Certified credentials on its website
• 5.0 stars from roughly 117 Google reviews as at November 2026

Cons

• Its site shows brand logos without saying which are batteries, panels or inverters
• A “lifetime” workmanship warranty is only as good as the company that stands behind it; get the written terms and the exclusions
• No prices published

Get a quote at osenergy.com.au.

Key facts. Enoggera base, serving Queensland and northern New South Wales according to its site.

Products and brands offered. Logos on its site include Jinko, Sigenergy, Pylontech, Victron Energy, Deye, Sungrow, Fronius and Tesla.

Warranty and after-sales support. The lifetime claim is the headline; ask what it excludes.

Best for buyers comparing several battery brands, including off-grid and hybrid setups. Look elsewhere if you want named models and prices up front.

Best for Scale and Tesla Plus VPP Options: Think Renewable

Think Renewable is a national installer founded in 2021 with a Brisbane office in Fortitude Valley. Our full Think Renewable review covers ratings and complaints in detail.

Pros

• 4.8 stars from roughly 316 Google reviews on its Fortitude Valley listing as at November 2026, the largest review base on this list
• Lists Tesla, Sungrow, Sofar, SolarEdge, Alpha and Sigenergy as partner brands site-wide
• Our review reports a stated 10-year workmanship warranty under its Think Care program

Cons

• Our review notes a minority of detailed negative ProductReview.com.au reviews about slow fault repairs and escalation
• Its site does not say which batteries it offers in Queensland, and does not say installs are in-house
• A young company that has grown by acquisition, which can stretch service teams

Get a quote at thinkrenewable.com.au.

Key facts. Fortitude Valley office with electrical licence number shown on its site. It also offers retrofit batteries for existing solar.

Products and brands offered. See Tesla Powerwall 3 if that is quoted.

Installation quality and reputation. Our Think Renewable review finds most installs praised and a smaller number of after-sales disputes.

Warranty and after-sales support. Ask who services the battery after install and how fast.

What customers praise and what complaints recur. Tidy crews and clear handover; after-sales delays in the minority of cases.

Best for buyers who want a large national brand with local presence. Look elsewhere if you want a small owner-run crew.

Best for Tesla and Premium Panels: Sunrays Power

Sunrays Power is a Coopers Plains business that says it has operated since 2015 with in-house engineers, designers and installers. It names Tesla Powerwall as its battery and lists a wide panel range.

Pros

• Says its team is in-house, and that it is a New Energy Tech approved seller and Clean Energy Council accredited designer
• Panels listed include LONGi, Canadian Solar, Jinko, Trina and REC; inverters include GoodWe, Sungrow, Fronius and SolarEdge
• 4.9 stars from roughly 83 Google reviews as at November 2026

Cons

• Names only Tesla Powerwall as a battery, with “other premium batteries” not named
• Does not publish a workmanship warranty term, only manufacturer warranties
• Also serves Victoria, New South Wales and South Australia, so Brisbane crews may be one of several teams

Get a quote at sunrayspower.com.au.

Key facts. Coopers Plains base; support teams described in Queensland, Victoria and New South Wales.

Pricing and value. Not published; the site shows estimated savings only.

Warranty and after-sales support. The site says it backs system operation for at least five years under the Clean Energy Council code; ask for the workmanship term.

Best for Powerwall buyers wanting a smaller alternative to the large national brands. Look elsewhere for non-Tesla battery choice.

Best Longest-Running Local: Local Power

Local Power Pty Ltd says it has been providing ethical solar in Queensland since 2007 from West End. That is the longest operating claim in this list, which matters because workmanship cover depends on the company still trading.

Pros

• Says it has operated since 2007, and shows a New Energy Tech Consumer Code approved seller logo and electrical licence 77257
• Logos for REC, Aiko, Sigenergy, SolarEdge, Fronius and BYD suggest battery and hybrid options
• 5.0 stars from roughly 40 Google reviews as at November 2026

Cons

• Only about 40 Google reviews, the smallest base here, so a perfect score is weak evidence
• Does not state whether crews are in-house, and does not publish a workmanship warranty term
• The site does not say which logos are batteries

Get a quote at localpower.net.au.

Key facts. West End base. Legal entity shown on its site as Local Power Pty Ltd, ABN 88 161 103 831. Not in our directory.

Installation quality and reputation. Reviews on its site describe its own crew, but we could not verify that independently.

Pricing and value. Says it offers transparent pricing with no hidden costs; no figures published.

Best for inner-west and south Brisbane buyers who want a long-running local. Look elsewhere if you want published brands, warranty and large-sample reviews.

How we reviewed

We started from a Google Maps search for solar battery installers around central Brisbane, our own directory listings and search results for Brisbane battery installers. We then removed the installers already covered in our best solar companies in Brisbane, Tesla Powerwall and Fronius guides, so this list adds new names. Several Maps listings share one Milton office address, which is common for lead generation and marketing entities, so we favoured companies with their own address, licence number and crew.

Each installer was assessed on stated install model, battery brands, workmanship warranty, published pricing, accreditation claims and review volume. Sources were company websites, Google Maps ratings as at November 2026 and our own directory. We could not confirm SolarQuotes or ProductReview.com.au ratings for most of these companies, so we do not report them. We requested no quotes, made no calls and no company paid for placement.

Our directory data from August 2026 shows 188 rated Queensland companies averaging 4.82 stars, so a 4.8 to 5.0 rating is normal here, not a differentiator.

Choosing a solar battery installer in Brisbane

Check accreditation yourself. The federal discount needs an installer accredited by Solar Accreditation Australia, and the seller should be on the Clean Energy Council’s New Energy Tech Consumer Code approved list. Solar Cobber does not verify accreditation; the company claims above are as stated on their sites.

Ask who actually installs. Custom Solar Power, Symons Energy and Optimum Solar Energy say they use no subcontractors. Get the same statement in your contract from whoever you choose.

Plan backup properly. Decide which circuits you want powered in an outage, and ask whether your switchboard needs work. Ask about heat, since Brisbane garages and west walls get hot.

Compare like for like. Quotes should name the battery model, usable capacity in kWh, certificate discount and installation date. See how to compare solar quotes.

FAQ

How much does a solar battery cost in Brisbane?

A 13.5 kWh solar battery typically costs about $11,000 to $15,000 installed in Brisbane before incentives, as at November 2026, and about $7,360 to $11,540 after the federal discount. Our Powerwall guide reports a Tesla Powerwall 3 at $15,000 to $17,000 before the discount. These are estimates drawn from our cost guides, not quotes. See our battery cost guide.

Is there a solar battery rebate in QLD?

There is no Queensland state battery rebate as at November 2026, but the federal Cheaper Home Batteries Program applies in Queensland. The state Battery Booster closed on 8 May 2024. The federal discount is worth about $3,460 to $3,640 on a 13.5 kWh battery installed by 31 December 2026.

Who are the best solar battery installers in Brisbane?

No single installer is best for everyone, but the seven here are all well rated on Google and each suits a different buyer. Custom Solar Power and Symons Energy suit in-house southside installs, while Think Renewable suits buyers who want a larger company. Get three quotes.

Should I buy a home battery in Brisbane now or wait?

Buying before 1 January 2027 usually earns a bigger federal discount, because the certificate factor falls from 6.8 to 5.7 per kWh. On a 13.5 kWh battery that is roughly $570 to $600 less. The date that counts is the installation date.

Do I need solar to get a home battery in Brisbane?

Yes, to get the federal discount the battery must be installed with new or existing rooftop solar. Grid-only batteries do not qualify, according to our rebate guide.

Do I have to join a VPP?

No. On-grid batteries must be capable of joining a virtual power plant (VPP) to get the federal discount, but joining one is optional. A VPP is an arrangement where a retailer or aggregator can draw on your battery in exchange for credits.

What happens if my battery installer goes out of business?

Manufacturer product warranties continue with the manufacturer, but the installer’s workmanship warranty usually ends. See our solar company failures tracker.

What are red flags in a battery quote?

No usable capacity in kWh, no battery model, a vague rebate line, large deposits and same-day signing pressure. Ask for the Energex export limit in writing.
