Sunboost Reviews 2026: Ratings, Complaints and Verdict

Sunboost reviews split sharply by platform. Sunboost is the trading name of Bell Solar Pty Ltd, a Sydney-based solar and battery retailer selling in every Australian state and territory. As at November 2026 it holds 4.8 stars from 21,436 reviews on ProductReview.com.au and 4.7 stars from roughly 7,100 Google reviews, but 3.5 stars from 328 ratings on SolarQuotes and 2.0 from 22 reviews on Trustpilot. Our verdict: a legitimate, high volume, low price retailer that suits simple jobs and careful buyers, with real after-sales risk. This is independent desk research; Solar Cobber did not contact Sunboost and was not paid. Our directory lists Sunboost in Eastern Creek, NSW and SunBoost Solar in Landsdale, WA.

Is Sunboost any good?

Sunboost is a legitimate, long-running retailer that delivers a tidy, cheap system for most customers, but its record when things go wrong is weaker than its headline ratings suggest. It has traded since 2017 and says it has completed more than 85,000 installations.

The gap between platforms is the signal that matters. Sunboost scores 4.8 on ProductReview.com.au and 4.7 on Google, where most reviews are short and written within days of installation. SolarQuotes follows up with customers about a year later, and there Sunboost scores 3.5 overall and 3.3 out of 5 for customer service. Fresh reviews measure install day. Later reviews measure what happens when an inverter fails, as we explain in why a five-star rating alone means little.

If your roof is simple, your switchboard is modern and you read the contract, Sunboost can be good value. If your job is complex, or you want one accountable installer for 10 years, pay more elsewhere.

What customers praise

Positive Sunboost reviews consistently mention price, punctual crews and a clean site, across ProductReview.com.au, Google and SolarQuotes in 2026.

Price. Reviewers say the quote was well below competitors. Value for money is Sunboost’s highest SolarQuotes sub-score at 3.7 out of 5.
Install day. Crews arriving on time, finishing in a day and tidying up is the most common ProductReview.com.au comment.
Handover. Many reviewers say the installer set up the monitoring app and explained the system.
Repeat business. Several 2026 reviewers returned to add a battery to an older Sunboost solar system.

Common Sunboost complaints

The most common Sunboost complaints in public reviews are slow after-sales service, extra costs raised on installation day, and payment demanded before installation. These are patterns in customer reviews, not findings by a court or regulator.

Slow fault and warranty response. The dominant negative theme on SolarQuotes and Trustpilot in 2025 and 2026 is faults taking weeks or months to fix. Some reviewers say they involved a state consumer agency first.
Fees on warranty work. Several SolarQuotes reviewers report a service or reinstallation fee requested before a technician attended an in-warranty fault.
No site inspection. Reviewers on ProductReview.com.au and SolarQuotes describe phone sales based on customer photos, then extra charges on the day for battery relocation, cabling or electrical work.
Payment before installation. Reviewers on both platforms describe repeated requests for the balance before installers arrived, which matches Sunboost’s published terms.
Variable subcontractors. Outcomes range from excellent to reports of misconfigured systems, roof leaks and non-compliant work.
Review requests. One 2026 SolarQuotes reviewer reports repeated requests for a positive Google review, and ProductReview.com.au shows “Incentivised Review” among labels frequently attached to Sunboost reviews.

Sunboost replies to negative reviews on ProductReview.com.au and publishes a complaints handling policy on its website.

Products and brands Sunboost installs

Sunboost currently installs mainly JA Solar and Jinko Solar panels with Fox ESS and Sigenergy inverters and batteries, according to its SolarQuotes profile checked in November 2026. Sunboost’s own solar page does not name panel models.

Sunboost solar panels: JA Solar and Jinko Solar. See our JA Solar DeepBlue 4.0 review and Jinko Tiger Neo review.
Sunboost battery range: the homepage advertises 14 kWh, 28 kWh and 42 kWh Fox ESS packages, covered in our Fox ESS EQ4800 battery review. Reviewers also report Sigenergy systems; see our Sigenergy SigenStor review.
Older systems: Trina and Seraphim panels with Solis, Growatt and Fronius inverters appear often in earlier reviews.

Under Sunboost’s terms, blackout backup is not included unless added at extra cost, and the installer has the final say on battery location under AS/NZS 5139:2019.

Sunboost prices

Sunboost does not publish package prices on its website as at November 2026. Its homepage asks for a postcode and advertises a battery “from only $99 per month” on finance, without stating the total price, term or battery size.

The only public price evidence is self-reported. SolarQuotes reviewers in 2025 and 2026 selected cost brackets of A$6,000 to A$8,000 for several battery-only installations, and A$12,500 to A$15,000 for one 15 kW solar system with a 42 kWh Fox ESS battery (December 2025). These are not quotes we obtained, and prices move with the federal discount.

Sunboost’s terms and conditions, checked November 2026, say the quoted price excludes the following unless the quote says otherwise.

Not included in the quoted price	What the terms say
Meter or switchboard upgrade	Customer arranges and pays
Export control device and distributor application	Additional cost payable by the customer
Extra cabling	Beyond 20 m DC (single storey), 40 m DC (double storey) or 5 m AC
Battery compliance items	Fire-rated mounting board, bollards, enclosure
Access and site work	Cherry picker, trenching, antenna relocation, old panel removal

One clause matters right now: Sunboost may increase the price if the system cannot be installed in the same calendar year as the quote. The federal battery discount steps down on 1 January 2027, so a late 2026 battery quote that slips into January can cost more. Our federal battery rebate guide explains the step-down, and how to compare solar quotes shows how to line up inclusions.

Warranty and after-sales support

Sunboost states a 10 year workmanship warranty and a 1 year limited property damage warranty in its published terms, with panels, inverters and batteries covered by each manufacturer’s warranty. A workmanship warranty is the retailer’s promise to fix installation faults; a product warranty is the manufacturer’s promise to fix faulty equipment.

As at November 2026, the Sunboost terms also say:

Warranty claims may not cover labour, travel and delivery costs, which are payable in advance.
The warranty is void if anyone else modifies the system or adds a battery.
On tile roofs the customer is asked to supply spare tiles, and some broken tiles are described as normal.
Sunboost’s liability is capped at the basic system cost.

Contract terms do not override the consumer guarantees in the Australian Consumer Law.

The workmanship warranty is honoured by Bell Solar Pty Ltd, not the subcontractor. If any retailer stops trading, its workmanship warranty generally ends and you rely on manufacturer warranties. We found no sign of financial difficulty at Sunboost, but see our Australian solar company failures tracker for why this matters.

Company background

Sunboost has operated since 2017 under Bell Solar Pty Ltd and is part of National Solar Energy Group, whose website also lists Australian Solar Designs, 3P Solar, Luxco Energy, German Energy and National Solar Services. Three public records are relevant to buyers.

Clean Energy Regulator undertaking, 2021. The Clean Energy Regulator records that Bell Solar Pty Ltd unknowingly received false information from a third party about who designed and installed 142 solar systems, and relied on it to improperly create 19,254 small-scale technology certificates. Bell Solar gave an enforceable undertaking on 1 April 2021 to inspect and rectify those systems and run a two year compliance program. The regulator lists it as completed.

NSW licence dispute, 2021. On 9 April 2021 the NSW Commissioner for Fair Trading refused to renew Bell Solar’s electrical contractor licence, citing supervision arrangements, the “fit and proper” test and 255 enquiries and complaints. Bell Solar disputed the findings and said complaints represented less than 1% of customers. In Bell Solar Pty Ltd v Commissioner for Fair Trading [2021] NSWCATOD 70 the tribunal stayed the refusal on 25 May 2021 pending review; that was not a final ruling. RenewEconomy’s One Step Off The Grid later updated its report to say NSW Fair Trading had renewed the licence for three years. Sunboost’s website lists NSW licence 309865C in November 2026. We did not check the register ourselves; you can at verify.licence.nsw.gov.au.

Tribunal appeal, 2021. In Bell Solar Pty Limited t/as Sunboost v Anderson [2021] NSWCATAP 278, decided 16 September 2021, the tribunal’s Appeal Panel dismissed Bell Solar’s appeal against an order to pay homeowners A$25,850 over a subcontracted installation found to have been done poorly.

We found no other public enforcement action against Sunboost as at November 2026.

Sunboost vs alternatives

Sunboost’s closest alternatives are other multi-state volume retailers. This table uses Google ratings checked in November 2026 and each company’s own published warranty statement.

Company	Google rating (count)	Workmanship warranty	Brands	Best for
Sunboost	4.7 (about 7,100, NSW listing)	10 years	JA Solar, Jinko, Fox ESS, Sigenergy	Lowest price on a simple job
Arise Solar	4.5 (about 7,300)	“Up to” 10 years	Jinko among others	Comparing two volume retailers on price
Solargain	4.6 (about 435, Perth head office)	5 years	Varies by branch	Buyers who want a local branch
Smart Energy	4.6 (503, Byron Bay head office)	5 years	Varies	Regional NSW and Queensland

Arise Solar’s NSW contractor licence renewal was refused by NSW Fair Trading in July 2026, and an interim NCAT order keeps it in force on the condition that Arise Solar does not enter contracts over A$20,000. Read our Arise Solar reviews, Solargain reviews and Smart Energy reviews for detail. Sydney buyers who want an installer with its own crews should see the best solar companies in Sydney.

Who Sunboost suits, and who should look elsewhere

Sunboost suits buyers who put price first and have a straightforward job: a single storey home, a sound roof, a modern switchboard, a short cable run and a compliant spot for a battery.

Look elsewhere if you have a fragile roof, an old switchboard, a granny flat on a sub-board, or no patience for chasing a call centre. Buyers who want a site inspection before the price is fixed, or want to hold back payment until the system works, will find Sunboost’s standard terms a poor fit. Our guide to choosing a solar installer sets out what a stronger process looks like.

Questions to ask Sunboost before you sign

Will someone inspect my roof, switchboard and battery location before the price is final?
Which licensed electrician will install my system, and what is their Solar Accreditation Australia number?
Does this quote include the switchboard work, export control device, distributor fee, bollards and fire-rated backing my site needs?
Is blackout backup included, and which circuits will it cover?
If installation slips past 31 December 2026, will the price change, and can I cancel for a full refund?
Can I pay the balance when the system is commissioned instead of before installation?
If my inverter or battery fails in year three, what will I pay for call-out, labour and reinstallation?

FAQ

Is Sunboost legit?

Yes, Sunboost is a legitimate business trading as Bell Solar Pty Ltd (ABN 69 617 634 876), registered since February 2017 and part of National Solar Energy Group. Legitimate does not mean right for every buyer: its SolarQuotes rating of 3.5 from 328 ratings shows a meaningful share of unhappy customers.

Who owns Sunboost?

Sunboost is operated by Bell Solar Pty Ltd, which describes itself on its website as a National Solar Energy Group (NSEG) company. Neither website publishes the names of the ultimate shareholders.

Is Sunboost CEC approved?

Sunboost’s website displays a New Energy Tech Consumer Code “Approved Seller” badge as at November 2026, and its terms say installations are done by Solar Accreditation Australia accredited electricians. Solar Cobber does not verify accreditation, so check the approved seller list and the installer register yourself.

How much does Sunboost charge?

Sunboost does not publish package prices as at November 2026, so you need a quote. SolarQuotes reviewers have reported paying A$6,000 to A$8,000 for battery-only installs in 2025 and 2026, before any site-specific extras listed in Sunboost’s terms.

What are the most common Sunboost complaints?

The most common Sunboost complaints in public reviews are slow responses to faults and warranty claims, extra costs raised on installation day, and requests for full payment before installation. These appear on SolarQuotes, Trustpilot and ProductReview.com.au in 2025 and 2026, and are customer reports rather than regulator findings.

Does Sunboost use subcontractors?

Yes, Sunboost’s published terms say it subcontracts installation to independent licensed electricians accredited by Solar Accreditation Australia. The terms say Sunboost will provide the installer’s accreditation details before work starts if you ask.

What happens to my warranty if Sunboost closes?

If Sunboost stopped trading, its 10 year workmanship warranty would generally end and you would rely on manufacturer warranties and the Australian Consumer Law. Keep your invoice, serial numbers and compliance certificate so you can claim directly from a manufacturer.
