Solargain reviews are mostly positive: as at November 2026 the Perth-based solar, battery and hot water retailer holds 4.6 stars from 995 reviews on ProductReview.com.au, 4.5 from 1,628 on Trustpilot and 4.3 from 1,121 ratings on SolarQuotes. Solargain (Solargain PV Pty Ltd) sells through its own offices and authorised distributors in Western Australia, Victoria, Queensland, New South Wales, South Australia and the ACT. Our verdict: a long-established, safe-enough choice with consistent praise for installation, but slower after-sales support than its sales process, and results that vary by branch. You can see Solargain’s listing in our directory. This is independent desk research; Solar Cobber did not contact Solargain and was not paid for this review.

Is Solargain any good?
Solargain is a good, established retailer with a large and mostly positive public review record, but reviewers say it is not always the cheapest and its after-sales service draws regular criticism. As at November 2026, three large review platforms put Solargain between 4.3 and 4.6 stars across more than 3,700 reviews in total.
The strengths are longevity (in solar PV since 2008), a wide product range and a dedicated service department. The weaknesses are a 5 year workmanship warranty that is shorter than the 10 years some local installers advertise, the use of contractors in some locations, and a pattern of reviews describing slow responses once something goes wrong.
Two things deserve attention before signing. First, Solargain controls the iStore brand that features in many of its advertised bundles, so compare an iStore quote against at least one independent brand. Second, a high star rating on its own tells you little, as we explain in the five-star problem with solar installer ratings.
What customers praise
Reviewers most often praise Solargain for clear quoting, punctual installers and tidy workmanship. On SolarQuotes, Solargain’s installation score of 4.5 out of 5 is its highest sub-score as at November 2026, ahead of quality of system (4.4), customer service (4.3) and value for money (4.2).
Recurring themes across ProductReview.com.au, Trustpilot and SolarQuotes in late 2026:
- Low-pressure sales. Many reviewers describe consultants who offered several options, including cheaper ones, and explained them clearly.
- Neat, fast installs. Reviews frequently mention crews arriving on time, finishing in a day and removing rubbish and old panels.
- Repeat customers. A noticeable share of reviews are from people returning to add a battery or a second system.
Common Solargain complaints
The most common Solargain complaints in public reviews concern after-sales support: slow replies, repeated follow-ups and faults that take a long time to resolve. SolarQuotes’ summary of Solargain reviews, read in November 2026, says after-sales support attracts more criticism than installation, mostly in the last year.
The patterns, by platform:
- Slow fault handling (SolarQuotes, Trustpilot, ProductReview.com.au). SolarQuotes’ summary counts 8 customers in two years reporting faults handled slowly or not at all. Trustpilot’s summary notes administrative delays and repeated follow-ups.
- Contractor workmanship (ProductReview.com.au, SolarQuotes). A small number of reviewers describe installs by subcontracted crews with poor roof sealing. SolarQuotes’ summary counts 2 reviewers alleging roof leaks that damaged ceilings.
- Export limits not explained (ProductReview.com.au). At least one reviewer says a system was limited to a lower output than expected and that this was not made clear at the sale.
- iStore metering and app issues (ProductReview.com.au). Some reviewers with iStore hybrid systems report problems with export data reaching their electricity retailer, or monitoring that did not work as expected.
- Call-out fees (Trustpilot). In an October 2026 reply on Trustpilot, Solargain said a service fee may apply to a warranty visit if the fault turns out not to be warrantable. The reviewer quoted a figure of A$298.
Solargain does respond. Trustpilot states that Solargain has replied to 100% of its negative reviews, typically within a week, and company replies are visible under most negative reviews on ProductReview.com.au. These are customer accounts, not findings by a regulator.
Products and brands Solargain installs
Solargain sells a wide multi-brand range, with its own iStore brand at the centre of many advertised packages. As at November 2026, the battery page on Solargain’s website lists iStore, Tesla Powerwall 3, Fronius Reserva, BYD Battery-Box HVS Premium, FranklinWH, Sungrow, Enphase, Huawei Luna, SolarEdge, Growatt and GoodWe.
For a Solargain battery quote, the products we have reviewed include the iStore battery, the Tesla Powerwall 3 and the BYD Battery-Box Premium.
SolarQuotes lists the panel brands Solargain currently installs as Aiko, Jinko, Seraphim, SunPower and Trina, and the inverter brands as Enphase, Fronius, GoodWe, iStore, SolarEdge, Solis and Sungrow. Fronius buyers can read our Fronius GEN24 Plus review.
Solargain prices
Solargain does not publish package prices: the special offer pages we opened in November 2026 either show no price or say to enquire.
SolarQuotes says its reviewers report paying A$5,000 to A$11,130 for 5 kW to 13 kW Solargain systems, and recent SolarQuotes reviewers place 13 kW solar and battery systems in the A$15,000 to A$20,000 band or higher. ProductReview.com.au shows an average reported purchase price of A$7,540 across all Solargain product types (both read in November 2026).
Read the conditions on any headline deal. The terms on Solargain’s battery-ready 6.6 kW offer say prices assume a single-storey home with a tin roof, single-phase power, one array of panels, suitable switchboard space and a cash purchase. Network application and meter replacement fees are extra, and finance is priced on the full recommended retail price rather than the special.
Battery bundles are advertised with the federal Cheaper Home Batteries Program discount, which steps down on 1 January 2027. Ask for the price before and after the discount, and use our guide on how to compare solar quotes to line it up against two other quotes.
Warranty and after-sales support
Solargain’s workmanship warranty is 5 years, according to the Longevity Guarantee page on its website checked in November 2026. The table below sets out the warranty terms Solargain publishes, checked in November 2026.
| Component | Term published by Solargain | Who stands behind it |
|---|---|---|
| Installation (workmanship) | 5 years | Solargain |
| Solar panels (product and performance) | 25 to 30 years | Panel manufacturer |
| Inverter | 10 to 12 years | Inverter manufacturer |
| Battery | 10 years, cycle limits apply | Battery manufacturer |
| iStore package (hybrid inverter and battery) | 10 years parts and labour, plus 2 year parts-only extension | iStore |
Solargain says that if a product manufacturer is no longer available, it will make good or find an equivalent replacement within the original warranty period. That is a company promise, not an insured warranty. If any retailer stops trading, workmanship cover ends and you rely on manufacturers and the Australian Consumer Law; see our Australian solar company failures tracker. Solargain also repairs systems installed by other companies and says it services more than 100 systems a week nationally.
Company background
Solargain is a privately held Australian company with no public enforcement history that we could find. According to its website, the business started as a one-person plumbing operation in Perth in 1994, became Solargain in 2005, moved into solar PV in 2008 and split into a hot water company and a solar PV company in 2009.
Who owns Solargain? ABN Lookup shows Solargain PV Pty Ltd as an Australian private company, and the company describes itself as 100% Australian owned. Its Modern Slavery Statement for the 2023-24 financial year (dated 4 December 2024, on the Australian Government register) was signed by directors Domenico Mercuri and Wayne Petridis. Shareholdings are not published.
That statement reports about 132 staff at 30 June 2024 across nine company sites, plus small regional businesses acting as Authorised Solargain Distributors and service agents. It says installation is carried out by Solargain employees or locally sourced contractors, and that Solargain has majority ownership of, and controls, iStore (QLD) Pty Ltd.
We found no public enforcement action against Solargain as at November 2026.

Who Solargain suits, and who should look elsewhere
Solargain suits buyers who value a long trading history and a broad range over the lowest price. It is a reasonable fit if you:
- want solar, a battery, an EV charger and hot water from one supplier
- live in regional WA, Victoria or Queensland where Solargain or a distributor has a local office
Get competing quotes if you want a 10 year workmanship warranty, if you want the installer who quotes to be the person on your roof, or if price is your main driver. Our guide on how to choose a solar installer covers what to check.
Questions to ask Solargain before you sign
- Is my branch a Solargain company office or an Authorised Solargain Distributor, and whose name and ABN is on the contract?
- Will Solargain employees or a contractor install my system, and who inspects the roof penetrations afterwards?
- Is the 5 year workmanship warranty written into my contract, and can it be extended?
- Will my system be export limited or output limited by the network, and to how many kW?
- If I am quoted iStore, what would the same system cost with an independent inverter and battery brand?
- What service or call-out fees apply during the warranty period, and when?
- What extra charges apply for my roof type, storeys, phases, switchboard and meter?
