RenewCo Solar reviews are strongly positive: as at November 2026 the Sydney installer holds 4.8 stars from 238 Google reviews and 4.9 from 412 ratings on SolarQuotes, plus a single 1 star review on ProductReview.com.au. RenewCo Solar is the trading name of RenewCo Energy Pty Ltd (ABN 94 648 642 540), based in Lane Cove West, NSW, and it sells mainly REC panels with Sigenergy inverters and batteries. Our verdict: a well reviewed, real company whose recurring weak spots are lead times and coordination between sales and install teams. We found no regulator action against it. It is not in our directory, so there is no Solar Cobber listing to link. This is independent desk research; Solar Cobber did not contact RenewCo Solar and was not paid for this review.

Is RenewCo Solar legit and any good?
RenewCo Solar is legit and, on the public evidence, a good choice for a Sydney household that wants a premium REC and Sigenergy system and can wait for installation. The company is a registered private company with an active ABN, a published address and hundreds of public reviews. Its ratings are high on Google and SolarQuotes, and the complaints we found are mostly about timing and communication, not about system quality.
Read the numbers with care. A single review makes up the whole ProductReview.com.au listing, so it says little either way, and a high rating alone is weak evidence (see our guide to the five-star problem). SolarQuotes is a quote comparison business rather than an independent regulator, so treat its ratings as one input, not an audit.

| Solar Junction (394) | 4.6 |
| 1KOMMA5 NSW (536) | 4.3 |
On Google, RenewCo Solar’s 4.8 sits in the middle of this group of large Sydney installers: below Platinum Solar Group and Sunray Power Solar, and above Solar Junction and 1KOMMA5.
What the star breakdown shows
The SolarQuotes page shows that 84% of RenewCo Solar’s 412 ratings are 5 stars and 1% are 1 or 2 stars.
Solar Cobber calculation. Each star count divided by 412: 346 five star is 84.0%, 58 four star is 14.1%, 4 three star is 1.0%, 3 two star is 0.7% and 1 one star is 0.2%. For comparison, 24 of 210 ratings (11.4%) for Solar Battery Group on the same platform are 1 or 2 star, as in our Solar Battery Group review.
Source: SolarQuotes RenewCo Solar listing, read November 2026; percentages are a Solar Cobber calculation. SolarQuotes says it has also removed 4 reviews. Google and ProductReview.com.au do not publish a star split we could read.
View the data as a table
| Share of ratings | |
|---|---|
| 5 star | 84.0% |
| 4 star | 14.1% |
| 3 star | 1.0% |
| 2 star | 0.7% |
| 1 star | 0.2% |
Only 8 of 412 ratings are below 4 stars. That is a very low share, and it also means the written complaints below come from a small group.
What customers praise
Public reviews on SolarQuotes and the company’s own Google testimonials praise the same things, read in November 2026:
- Sales advice. Reviewers describe patient, knowledgeable, non-pushy salespeople, especially after an in-person site visit.
- Price. Reviewers call pricing transparent and competitive. SolarQuotes says reviewers report paying about A$7,000 to A$26,000 for systems from 6.6 kW to 20 kW; we could not tell which of those include batteries.
- Installation crews. Many describe punctual, tidy and professional installers who explained the system and the monitoring app.
- Follow-up. Reviewers mention check-in calls after installation and help choosing an electricity retailer. One Google testimonial on the company’s site describes RenewCo upgrading a battery system at its own cost after a design shortfall; that is a testimonial the company chose to publish.
Common RenewCo Solar complaints
The most common RenewCo Solar complaints are about timing and coordination, not about the hardware. These are patterns across SolarQuotes and ProductReview.com.au in November 2026, not findings about any single case.
- Long waits before installation. Several SolarQuotes reviewers, including some giving 4 or 5 stars, mention waits of two to three months or more.
- Installs not finished in one visit. A SolarQuotes review dated 9 August 2026 gives 2 out of 5 for installation and customer service and describes late arrival, work running into the evening, an incomplete install and several return visits.
- Gaps between sales, installers and the office. The same review and others describe no single point of contact and information not reaching the crew.
- Subcontractors. A few reviewers say subcontractors were used and they were not told beforehand. The SolarQuotes profile describes a hybrid of in-house staff and contractors, while the company website stresses a fully in-house team, so ask which applies to your job.
- Monitoring data. A few reviewers mention app connectivity or consumption figures that did not match their retailer’s data.
- Rescheduling and a delayed refund (one review). The only ProductReview.com.au review, about December 2025, alleges an installation date moved at short notice, a late arrival and a promised refund that had not been paid. It is one unverified account and we cannot see how it ended.
On responses, RenewCo Solar replies publicly to its most critical SolarQuotes reviews with dated, detailed accounts of its contact records, apologises for specific problems and disputes the reviewer’s description of its service. We could not read individual Google reviews, so we have not described Google complaint themes.
Products and brands RenewCo Solar installs
RenewCo Solar mainly installs REC panels with Sigenergy inverters and batteries. Its website also has pages for SolarEdge, Sungrow and the Tesla Powerwall 2 and 3, and it lists a Sigenergy Platinum Partner status that we could not independently check.
We have reviewed several of these products: the REC Alpha Pure-RX (the company’s pages describe the Pure-R series), the Sigenergy SigenStor, the Tesla Powerwall 3 and the SolarEdge Home Battery. Our Sigenergy Australia guide covers the brand and its warranty terms.
The company’s REC Alpha Pure-R page states 20 to 22 per cent class efficiency (20.7% to 22.3%), a 20 year product warranty and a 25 year performance warranty, with optional labour cover under REC’s ProTrust scheme when installed by a certified professional. Its home page describes a 25 year warranty on components, which differs, so check which warranty your contract names.
RenewCo Solar prices
RenewCo Solar does not publish fixed prices. Its website offers a free solar assessment and a detailed scope and quote, plus calculators that give an estimate rather than a quote.
The only price evidence we found is from reviewers: SolarQuotes says they report about A$7,000 to A$26,000 for systems from 6.6 kW to 20 kW. For context, our solar panel cost guide puts a standard 6 kW system in Sydney at A$5,800 and a 10 kW system at A$8,810 after the STC discount including GST, according to the Solar Choice Price Index dated 1 November 2026. A premium REC and Sigenergy package with a battery will usually sit above that index, so compare like with like.
What the federal battery discount is worth
RenewCo Solar’s website banner advertises an “$18,500 Federal Battery Rebate” and “$3000 NSW Battery Incentive”. We could not reproduce either number from the program rules in our battery rebate guide and state battery rebate guide, so ask for the working behind them.
Solar Cobber calculation. Certificates = usable kWh in the first 14 kWh multiplied by 6.8, plus kWh from 14 to 28 multiplied by 6.8 and by 60%. Value = whole certificates multiplied by A$38 to A$40, for installs between 1 May and 31 December 2026.
| Usable capacity | STCs (whole certificates) | Discount at A$38 | Discount at A$40 |
|---|---|---|---|
| 10 kWh | 68 | A$2,584 | A$2,720 |
| 13.5 kWh | 91 | A$3,458 | A$3,640 |
| 20 kWh | 119 | A$4,522 | A$4,760 |
- At A$38 per STC
- At A$40 per STC
Source: Solar Cobber calculation from the Cheaper Home Batteries Program factor and size tiers in our state battery rebate guide. The discount steps down on 1 January 2027. Certificate prices are the range used in our rebate guide.
View the data as a table
| At A$38 per STC | At A$40 per STC | |
|---|---|---|
| 10 kWh | A$2,584 | A$2,720 |
| 13.5 kWh | A$3,458 | A$3,640 |
| 20 kWh | A$4,522 | A$4,760 |
On our figures a 20 kWh battery earns about A$4,760 at most, so a headline well above that needs an explanation, such as other discounts or a bundled system price. The NSW figure is likely the Peak Demand Reduction Scheme virtual power plant incentive described in our NSW rebate guide, which varies and is not a flat amount.
Warranty and after-sales support
RenewCo Solar’s SolarQuotes profile states a 10 year workmanship guarantee, and its website offers complimentary 24/7 support and Australian-based after-sales support. We did not find the workmanship terms in writing on the pages we read, so get them in your contract.
The product warranties come from the manufacturers, for example REC for panels and Sigenergy for its inverters and batteries. The workmanship promise comes from RenewCo Energy Pty Ltd, so it would generally end if the company stopped trading. Our solar company failures tracker explains that risk. Ask who handles warranty claims on your equipment, and whether they run through RenewCo or the manufacturer.
Company background
RenewCo Energy Pty Ltd has an ABN active from 12 March 2021, and the business describes itself as family owned, with Matthew Summerville as chief executive and owner and Mark Summerville as finance manager and owner on its About page. In 2025 RenewCo Solar partnered with Better Call Solar, a NSW installer; one SolarQuotes reviewer says problems arose after RenewCo took over a company that had installed their system. The company says its team has 15 years of experience, which predates the company itself.
We found no public enforcement action against RenewCo Solar or RenewCo Energy Pty Ltd as at November 2026. We searched the ACCC and NSW Fair Trading notices, the Clean Energy Regulator’s published compliance updates and general web results, and did not read the NSW Civil and Administrative Tribunal’s records directly. Customer complaints alone are not evidence of wrongdoing, and an absence of action is not a guarantee of quality.

Yes, they are strongly positive. As at November 2026 the company holds 4.8 from 238 Google reviews and 4.9 from 412 ratings on SolarQuotes, though its ProductReview.com.au listing has one 1 star review. Treat comparison-site ratings as one input among several.
What are the most common RenewCo Solar complaints?
The most common complaints are long waits before installation and poor coordination between sales, office and installers, followed by incomplete first visits. These are patterns on SolarQuotes and ProductReview.com.au, not proven faults. The company replies publicly to critical SolarQuotes reviews.
Who owns RenewCo Solar?
RenewCo Solar is owned by the Summerville family, according to its own website, which names Matthew Summerville and Mark Summerville as owners. The legal entity is RenewCo Energy Pty Ltd. We could not confirm the shareholding independently.
Is RenewCo Solar CEC approved?
The company shows New Energy Tech Consumer Code and Solar Accreditation Australia approval on its SolarQuotes profile, and says its battery installers are accredited. Solar Cobber does not verify this, so check the Clean Energy Council approved retailer list and the Solar Accreditation Australia register yourself.
How much does RenewCo Solar charge?
RenewCo Solar does not publish prices. SolarQuotes says reviewers report about A$7,000 to A$26,000 for systems from 6.6 kW to 20 kW, and we could not tell which include batteries. Ask for a written quote showing the STC discount as a separate line.
What happens to my warranty if RenewCo Solar closes?
