Advantage Solar reviews are strong where the volume is: 4.7 stars from 543 Google reviews and 4.9 from 186 Trustpilot reviews, as at November 2026. This page covers Advantage Solar of 79 Rokeby Street, Collingwood, Melbourne (advantagesolar.com.au), a solar, battery and heat pump retailer that also lists a Perth office. Our verdict: the installation feedback is consistently good, but the company publishes no prices, brands or warranty lengths, and its “zero upfront” Solar Saver Plan needs the written terms checked before you sign.
This is independent desk research. Solar Cobber did not contact Advantage Solar, was not paid by it, and has not used its services. The company is listed in our directory at /companies/advantage-solar.

Which Advantage Solar is this?
Several unrelated businesses use similar names, so check you have the right one. This page covers Advantage Solar at 79 Rokeby Street, Collingwood VIC 3066, phone 1300 449 873, website advantagesolar.com.au. Other businesses with similar names exist, including a separate “Solar Advantage” listed on some review sites, so match the address and ABN.
One trap: some directory listings show ABN 32 006 824 148 next to this address. ABN Lookup shows that number belongs to the Australian Solar Energy Society Ltd (the Smart Energy Council), not to the installer. Use the ABN in the table below, and check it yourself on ABN Lookup.

Is Advantage Solar any good?
Advantage Solar looks like a well-regarded Melbourne retailer with an unusually high recent review volume, and the installation feedback is consistently positive. Across Google, Trustpilot and SolarQuotes the praise centres on helpful sales staff, tidy installs and fast timelines.
The weak points are about what is not shown. There are no published prices, no named brands and no stated warranty lengths, so a buyer has to get all of that in writing. The two negative signals we found are a ProductReview.com.au review about the “zero bills” sales pitch and ongoing monthly payments, and a 1 star SolarQuotes review about a battery that was not working. Neither proves a pattern, but both point to the same advice: get the battery, finance and warranty terms in the contract. Read why a high star rating alone means little before relying on the headline numbers.
How the ratings compare across platforms
Advantage Solar scores between 4.3 and 4.9 on the three platforms with meaningful numbers, and the two big ones sit close together. The chart shows the average rating on each platform.

| Rating | |
|---|---|
| Trustpilot | 4.9 stars |
| 4.7 stars | |
| SolarQuotes | 4.3 stars |
| ProductReview.com.au | 3.5 stars |
Trustpilot and Google rate Advantage Solar highest, while the two platforms with the fewest reviews (SolarQuotes with 10 and ProductReview.com.au with 2) rate it lowest.
The ratings only mean something next to their sample sizes, which the next chart shows.

| Reviews | |
|---|---|
| 543 | |
| Trustpilot | 186 |
| SolarQuotes | 10 |
| ProductReview.com.au | 2 |
Google (543) and Trustpilot (186) hold 98% of the 741 public ratings, so the 3.5 star ProductReview.com.au score rests on only two reviews.
Solar Cobber calculation: weighting each platform’s rating by its review count gives (4.7 x 543 + 4.9 x 186 + 4.3 x 10 + 3.5 x 2) / 741 = 4.74 stars across 741 ratings. That is a blended figure for comparison only, because platforms collect reviews differently.
What customers praise
Customers across platforms praise the sales advice, the installation crews and the speed. These themes recur in the Trustpilot sample we read and in the ten SolarQuotes reviews.
- Sales staff who explain things. Trustpilot reviewers describe patient consultants who explained pricing, warranties and government rebates. One SolarQuotes reviewer from April 2024 praised help with solar and heat pump rebate paperwork.
- Tidy, on-time installs. SolarQuotes reviews from 2024 to 2026 describe clean, professional work, with installs ranging from a single day after approval to about four weeks from order to commissioning.
- App walkthroughs. A July 2026 SolarQuotes reviewer said they were shown how to use the monitoring app.
- Rebate handling. Several reviewers mention the company dealt with the rebate paperwork.
SolarQuotes also shows category averages from those ten ratings, with installation the strongest.

| Rating | |
|---|---|
| Installation | 4.5 |
| Service | 4.4 |
| Quality | 4.3 |
| Value | 4.1 |
Installation scores 4.5 and value for money 4.1, the lowest of the four, so buyers rate the work above the price.
Common Advantage Solar complaints
Complaints are rare in the public reviews, and the themes below are patterns from very small samples. We do not name reviewers.
- “Zero bills” expectations (ProductReview.com.au). One of the two ProductReview.com.au reviews says the sales pitch promised “zero bills”, that power bills stayed similar or higher, and that a monthly equipment cost applied. The reviewer was unhappy with the company’s response. The company’s own site uses wording such as “zero bills*” on its social pages, so ask exactly what the asterisk covers.
- Battery not working (SolarQuotes). A June 2025 reviewer gave 1 star and said the battery was not working.
- Slow battery follow-up (SolarQuotes). A January 2025 reviewer rated the install well but said a battery quote request was not answered in time.
- Reply behaviour (Trustpilot). Trustpilot shows a notice that the company has not replied to negative reviews. With 96% five star reviews there are very few negatives to reply to, so read this as a note about process rather than a finding.
The Trustpilot page also shows the star split.
| Trustpilot stars | Share of 186 reviews (November 2026) |
|---|---|
| 5 stars | 96% |
| 4 stars | 3% |
| 3 stars | under 1% |
| 2 stars | under 1% |
| 1 star | 0% |
Trustpilot also notes the company has no recent history of asking customers for reviews, which it says can mean the reviews are not fully representative. Treat the 96% as a strong signal, not a guarantee.
Products and brands Advantage Solar installs
Advantage Solar does not name panel, inverter or battery brands on its main page, saying only that it partners with leading manufacturers. SolarQuotes lists past installs of Sungrow (3 systems), Fox ESS, GoodWe and Sofar, with Fox ESS and GoodWe batteries and an Emerald Energy heat pump.
We have independent reviews of several of these. See our Sungrow SBR battery review, Sungrow SH-RS hybrid inverter review, GoodWe Lynx Home battery review and Fox ESS battery review. Ask for the exact model numbers on the quote, then check them against the Clean Energy Council approved product lists.
Advantage Solar prices
Advantage Solar does not publish system prices on its website as at November 2026. It advertises a limited-time bundle discount and a Solar Saver Plan marketed as “zero upfront costs”, subject to eligibility, with no rates or term published.
A “zero upfront” plan is usually finance or a subscription, so the total you repay over the term can exceed the cash price. We could not confirm who provides the finance or whether it is a loan, lease or power purchase agreement. Ask for the contract and compare it with a cash quote and a standard green loan, using our guides to solar loans and green loans and how to compare solar quotes. Victorian rebate settings are in our Victorian solar rebate guide.
Warranty and after-sales support
Advantage Solar’s website describes a “Gold Standard Guarantee” with a free service plan on every installation, and says it will act quickly if a system fails. It does not state a workmanship warranty length on the main page and links a separate Warranty and Dispute Policy, which we did not find a way to read in full. Ask for the length in years in writing.
Manufacturer warranties come from the brand and depend on that brand having a local entity. If an installer stops trading, workmanship cover can disappear even though product warranties remain, so read our tracker of Australian solar company failures and ask whether the workmanship warranty is insurance backed.
Company background
Advantage Solar is a trading name of Nilnuk Pty Ltd, a Victorian private company with an active ABN from 7 September 2020, and the business name was registered on 2 August 2022, according to ABN Lookup in November 2026. A Smart Energy Council directory entry written by the company says it has over 10 years in the industry, covering project development, installation, manufacturing and wholesale. We could not reconcile that with the register dates and did not find whether it traded earlier under another entity. Ask the company.
The website lists Collingwood and West Perth offices, and describes installers as CEC accredited. We found no public enforcement action against Advantage Solar or Nilnuk Pty Ltd as at November 2026 in a search of regulator, court and tribunal reporting, but that is not a substitute for checking Consumer Affairs Victoria, VCAT and the Federal Court yourself.

Who Advantage Solar suits, and who should look elsewhere
Advantage Solar suits Melbourne and regional Victorian households that want a retailer with strong recent reviews, help with rebate paperwork and a tidy install, and who will read the contract and compare it against two other quotes.
Look elsewhere, or negotiate harder, if you want published prices and named brands before a sales visit, if you are drawn mainly by “zero upfront” with no wish to read finance terms, or if you want a firm that has a long public record of resolving disputes. Households in Western Australia should also confirm which office would service them.
