Mackay is a smaller solar market than Brisbane or Townsville, but strong sun, high air-conditioning loads and a mining-region economy keep plenty of households and businesses shopping for panels. This guide reviews six companies that install here: Green Energy Technologies, Hybrid Solar Solutions Australia, Prestige Renewables, GI Energy, Horan and Bird Solar and Snap Solar, compared on experience, accreditation, equipment range, warranties, pricing signals and customer review patterns. Everything is independent desk research based on company websites, accreditation records, public customer reviews and published pricing. We did not visit these companies, request quotes or speak to them, and nobody paid to be included. By the end you will know who to call first, the trade-offs each carries, and what to ask before paying a deposit.

Best Overall: Green Energy Technologies
Green Energy Technologies (GET) is the strongest all-round choice for Mackay homeowners. Founded in the Whitsundays in 2009, it runs an office at 37 Evans Avenue in North Mackay and covers the coast from Brisbane to Townsville. The clincher: the company states plainly that it does not employ contractors, so the crew on your roof works for GET. In a market where subcontracting is common, that matters.
Pros
- In-house crews, no subcontractors, per the company’s own website
- SAA-accredited installers and designers with published licence numbers
- Company claims it will fix installation faults free for the life of the system
Cons
- Does not publish its panel and inverter brand lineup online, so you cannot compare equipment before the sales call
- The lifetime workmanship claim has no published terms document, so get it in writing on your quote
- Review volume is modest for its age (4.6 stars from about 75 SolarQuotes reviews as of July 2026)

Key facts. Operating since 2009, with offices in Mackay, the Whitsundays and Townsville, published accreditation and electrical contractor licence numbers, and the SAA logo on its site.
Why we selected them. Local base, long history, in-house crews and full accreditation. Nothing else in Mackay ticks all four boxes.
Products and brands. Grid-connect solar, batteries, off-grid and commercial systems. Brands are not published, so ask for datasheets and check each brand has an Australian support office.
Installation quality and reputation. The no-contractors policy keeps accountability in one place, and we found no recurring complaint theme in public reviews.
Pricing and value. Not published; expect quotes above the bargain end given the in-house model. Finance is advertised, including an offer covering the first three months of repayments.
Warranty and after-sales. Free repair of installation faults for the system’s life beats the industry-standard 10 years, so make sure the exact wording lands on your contract.
Praise and complaints. Customers repeatedly praise clear explanations and tidy one-day installs; the thin review footprint means less independent data than rivals.
Best for / look elsewhere. Best for locals who want a nearby office and the same company on the roof and on the phone. Look elsewhere if you want a published brand list before the sales call.
Best for Batteries: Hybrid Solar Solutions Australia
Hybrid Solar Solutions Australia is a high-volume Queensland installer with the widest published battery range of any company servicing Mackay: Sigenergy, Tesla, BYD, Alpha ESS, Anker Solix and ByteWatt. With the federal Cheaper Home Batteries Program cutting installed battery costs by roughly 30 per cent since July 2025, battery-first shoppers should look here. The catch: it is Brisbane-based and services Mackay from a distance.
Pros
- 10-year workmanship warranty covering faulty installation, roof leaks and property damage
- NETCC approved seller with over 8,000 installs, per the company
- 4.9 stars from about 509 Google reviews and 4.9 from about 98 ProductReview reviews as of July 2026, as reported on its website
Cons
- Head office is in Brisbane (Underwood), roughly 950km away, so site visits and warranty callouts depend on travelling or regional crews
- Does not state whether regional installs are in-house or subcontracted, so ask directly
- No Mackay office means after-sales support is phone-first, not drop-in
Get a quote at hybridsolarsolutions.com.au or browse all Mackay installers in our directory.
Key facts. Over a decade in business, per the company; NETCC approved seller with accredited installers, servicing south-east Queensland plus regional centres including Mackay.
Why we selected them. The right battery depends on your usage, and nobody else servicing Mackay publishes a range this wide with reviews this strong.
Products and brands. Panels from Longi, Jinko, REC, Canadian Solar and JA Solar among others; inverters from Fronius, Sungrow, GoodWe, SolarEdge and Enphase; batteries as above.
Installation quality and reputation. Review sentiment is strongly positive on communication and tidiness, but the regional delivery model is not documented, so ask who attends your install.
Pricing and value. Not published, but high-volume operators usually price competitively on popular package sizes. Compare like-for-like using our quote comparison guide.
Warranty and after-sales. The 10-year workmanship warranty is clearly documented, better than several locals who publish nothing. Distance is the practical risk, not the paperwork.
Praise and complaints. Praise centres on smooth quoting, fast installs and pricing. The pattern to watch with any travelling installer is slow rectification visits, so ask for a committed response time in writing.
Best for / look elsewhere. Best for battery or hybrid systems where brand choice and documented warranties matter most. Look elsewhere if same-week local service is your top priority.
Best for Customer Service: Prestige Renewables
Prestige Renewables is headquartered at 2/31 Iridium Drive in Paget, with offices in Cairns, Townsville and the Sunshine Coast and a claimed team of over 70 staff across Queensland. Its review pattern is the best of any Mackay-based company we checked: 4.9 stars from about 34 SolarQuotes reviews as of July 2026, with customers repeatedly describing fast quote-to-install timelines.
Pros
- Head office in Paget, so sales, install and support are all local
- In-house installation teams, per the company
- Reviews consistently describe a three-week or faster quote-to-install turnaround
Cons
- Does not publish a workmanship warranty length, a gap rivals like Hybrid Solar Solutions (10 years) do not have
- Founding year is not published and the company only appears on SolarQuotes from late 2023, so the long-term track record is hard to verify
- Review volume is still small compared with the bigger operators
Get a quote at prestigerenewables.com.au or browse all Mackay installers in our directory.
Key facts. Paget head office, Queensland electrical contractor licence 87751, CEC-accredited installers, residential 5kW to 15kW, commercial past 100kW.
Why we selected them. Prestige’s review sentiment is unusually consistent: clear communication, no hard sell, clean installs, quick grid connection paperwork.
Products and brands. Panels from Longi, AIKO and TCL, inverters from Sungrow and GoodWe, batteries including Tesla and Sungrow. A sensible mid-to-premium lineup with Australian support agents.
Installation quality and reputation. In-house teams and a claimed 98.7 per cent satisfaction rate, with no recurring complaint theme found, though the review base is young.
Pricing and value. Not published; reviewers describe pricing as reasonable rather than cheapest. Get its quote alongside GET’s for a local comparison.
Warranty and after-sales. The missing workmanship warranty number is the real weakness. Ask for it in writing and do not accept “industry standard” as an answer.
Praise and complaints. Praise: speed, professionalism, tidiness, no-pressure sales. Nothing recurring on the complaint side that we could verify.
Best for / look elsewhere. Best for buyers who value responsiveness and a local office. Look elsewhere if you want a long review history or a documented decade-long workmanship warranty.
Best for Commercial and Industrial: GI Energy
Mackay’s mining-services economy means the sheds in Paget carry serious daytime loads, and GI Energy, founded in 2011, is the commercial specialist on this list. Its case studies include a 61.38kW commercial system in Mackay reported to have paid for itself in under four years, plus projects at the 515kW scale elsewhere. It is a CEC Approved Solar Retailer, NETCC approved seller, Tesla certified installer and Enphase Gold installer.
Pros
- Proven commercial capability, including a documented Mackay install with sub-four-year payback
- Founded 2011, with 4.7 stars from about 256 SolarQuotes reviews as of July 2026
- In-house electrical engineers and CEC-accredited designers for larger projects
Cons
- No Mackay office; head office is in Loganholme near Brisbane, so residential after-sales runs at a distance
- Residential customers will likely get more responsive service from a local firm; GI’s strength is clearly commercial
- The lifetime service guarantee has no published terms document, so confirm what it covers
Get a quote at gienergy.com.au or browse all Mackay installers in our directory.
Key facts. Operating since 2011 as a CEC Approved Solar Retailer and NETCC approved seller, servicing Queensland, New South Wales, Western Australia and South Australia.
Why we selected them. Commercial solar means load profiling, network approvals and structural engineering, and GI Energy documents that capability better than anyone else active in Mackay.
Products and brands. The broadest published kit list on this page: Fronius, Sungrow, SMA and Enphase inverters; Trina, REC, Tindo and Longi panels; Tesla Powerwall 3, Sigenergy and BYD batteries; Clenergy mounting and car-park structures.
Installation quality and reputation. Reviews describe a professional, low-pressure process, and in-house engineering depth is a genuine quality signal for complex jobs.
Pricing and value. Not published, which is normal for per-project commercial pricing. Ask for a payback model based on your actual interval data.
Warranty and after-sales. Lifetime service guarantee plus manufacturer warranties. Ask who performs warranty work in Mackay and how fast.
Praise and complaints. Praise: seamless process, capable technical staff, good ROI outcomes. The distance issue is the recurring caveat for regional residential customers.
Best for / look elsewhere. Best for Mackay businesses, farms and industrial sheds. Homeowners wanting a local point of contact should start with GET or Prestige.
Best for Finance Options: Horan and Bird Solar
Horan and Bird Solar has operated since 2004, the longest run on this list. The Townsville-based company keeps a Mackay office at Unit 4/12 Carl Court, Rural View, and claims around 30,000 customers. What earns its category win is payment flexibility: power purchase agreements (PPAs) and no-upfront-cost solar and battery plans, which few Mackay competitors offer.
Pros
- Established 2004, with a physical Mackay-area office
- PPAs and no-upfront-cost finance for households and businesses
- Five-time Master Electricians of the Year winner
Cons
- Published battery range centres on Fox ESS and HINEN, both value-tier brands; buyers wanting Tesla or Sigenergy must look elsewhere
- No separately published rating or review count for the Mackay branch, so local service quality is harder to verify than for rivals
- No-upfront and PPA deals cost more over the contract term than paying cash, so read the total-cost numbers carefully
Get a quote at horanandbirdsolar.com.au or browse all Mackay installers in our directory.
Key facts. Founded 2004, offices in Townsville, Cairns and Rural View near Mackay, published electrical licence 92634, Gold Master Electrician certification.
Why we selected them. Twenty-two years of operation matters in an industry where installers regularly disappear, and its finance options fill a niche nobody else here covers.
Products and brands. Panels with up to 12-year product and 25-year output warranties, Fox ESS and HINEN batteries, EV chargers. The full panel brand list is not published, so ask.
Installation quality and reputation. The award history and longevity point to solid workmanship; in-house versus subcontracted crews for the Mackay area is not specified, so ask.
Pricing and value. Not published. On finance, compare the total repayment against a cash quote from a local rival before deciding.
Warranty and after-sales. Manufacturer warranties are clearly stated; a specific workmanship warranty length is not, a gap for a company of this standing. Its service and maintenance department with claimed 24/7 support is a plus for long-term owners.
Praise and complaints. Longevity and professionalism are the recurring positives. The standing caution with any PPA provider is contract length and exit terms, not install quality.
Best for / look elsewhere. Best for buyers who do not want to pay upfront and anyone who prioritises a company likely to still exist in year 15 of a warranty. Look elsewhere for premium battery brands.
Best Local Newcomer: Snap Solar
Snap Solar runs from 1/18 Central Park Drive in Paget with a second office on the Sunshine Coast, pitching itself as a budget-friendly local option with $0 upfront finance. It says more than 500 locals have used it, and it holds 4.7 stars on SolarQuotes, although from only five reviews since being listed in October 2025.
Pros
- Genuine Mackay base in Paget, not a fly-in operation
- $0 upfront finance advertised
- Early reviews are positive (4.7 stars on SolarQuotes as of July 2026)
Cons
- Very short verifiable track record: on SolarQuotes only since October 2025 with five reviews, so long-term workmanship and after-sales patterns are unproven
- Publishes neither its equipment brands nor a workmanship warranty length on its website, the two most important pieces of pre-quote information
- Founding year not published, making due diligence harder
Get a quote at snapsolar.com.au or browse all Mackay installers in our directory.
Key facts. Offices in Paget (Mackay) and Baringa (Sunshine Coast), 500-plus claimed local customers. Accreditation details are not published; verify SAA and NETCC status before signing.
Why we selected them. Small markets need credible budget options, and a Paget address plus positive early reviews earns Snap a spot.
Products and brands. “Panels, inverters and batteries selected for long-term reliability”, per the company, with no named brands. Insist on datasheets and check each brand’s Australian support presence.
Installation quality and reputation. Too early to judge from public data. Early signals are good; the sample is tiny.
Pricing and value. Not published, but its positioning and finance offer target the value end. Cheap is fine if the components and warranty stack up; see our installer choice guide.
Warranty and after-sales. Not published. Do not sign without a written workmanship warranty of at least 5 years, preferably 10.
Praise and complaints. Early reviewers praise friendly, straightforward service. No complaint pattern exists yet, which reflects the short history.
Best for / look elsewhere. Best for budget-conscious buyers who will do the verification legwork. Look elsewhere if you want a long track record or documented warranties.
How We Reviewed
We built a shortlist from search results, SolarQuotes and ProductReview listings for Mackay and local directories, then confirmed from each company’s own website that it installs in the Mackay region. We assessed reputation and years operating, equipment quality and brand range, installation model (in-house versus subcontracted where discoverable), pricing signals, workmanship warranty, customer service patterns, review volume and after-sales support. Sources were company websites, review platform listings, accreditation records and published case studies, checked in July 2026. This is desk research: we did not request quotes, contact the companies or test installations, and no company paid for inclusion. Where a fact could not be verified, we said “not published” rather than guessing.
Choosing a Solar Company in Mackay
Check accreditation properly. Installer accreditation moved from the Clean Energy Council to Solar Accreditation Australia (SAA) in 2024, and reputable retailers are approved sellers under the New Energy Tech Consumer Code (NETCC). Ask for the installer’s SAA number and look the retailer up on the NETCC list.
Ask about cyclone rating. Mackay sits in wind region C under the Australian wind loading standard, so racking, fixings and panel attachment must be engineered for cyclonic winds. Get written confirmation that the mounting system is certified for region C on your roof type.
Understand Ergon’s rules. Mackay is on the Ergon Energy network, where single-phase homes are commonly limited to 5kVA of export and larger or three-phase systems need network approval. Ask who lodges the Ergon connection application and what export limit your design assumes.
In-house or subcontracted. GET and Prestige advertise in-house crews. For the others, ask who attends your roof and who is accountable for defects, in writing.
Warranties, in writing. You want three numbers: panel product warranty (25 years is common), inverter warranty (5 to 10 years), and the installer’s own workmanship warranty (10 years is the benchmark; make them commit on the quote).
Monitoring and after-sales. Consumption monitoring is the only way you will notice underperformance, so ask what is included and what a callout costs after year one.
Rebates. The federal STC incentive discounts every eligible system at the point of sale (how STCs work), and the Cheaper Home Batteries Program has cut installed battery costs by roughly 30 per cent since July 2025. Queensland has no ongoing state rebate on top, so any “exclusive government deal” in a sales pitch is a red flag.
Quotes and timing. Get three quotes with like-for-like specs (our comparison guide), and remember the wet season: November to April installs can slip with weather. For more companies, see our Queensland top installers page and the full directory.
FAQ
How much does a solar system cost in Mackay? As of July 2026, installers servicing Mackay advertised roughly $5,500 to $6,500 for a 6.6kW system after the STC discount, with well-specced systems from established locals often costing more. Treat any quote far below that floor with suspicion.
How many quotes should I get? Three: one Mackay-based company, one high-volume operator and one wildcard, all quoting identical system sizes with named components.
Which warranties actually matter? The workmanship warranty matters most, because installation faults (leaks, loose connections, cable damage) are the most common real-world problems. Then the inverter warranty, because inverters fail before panels do.
Are cheap installers safe? Sometimes, but the discount comes from somewhere: unnamed brands, subcontracted labour, no local service, or a company built to fold and relaunch. If a cheap quote names good components and carries a written 10-year workmanship warranty from a NETCC approved seller, consider it. Otherwise walk away.
How do I check an installer is legitimate? Ask for their SAA accreditation number and Queensland electrical contractor licence, then verify both online. Check the retailer against the NETCC list, and look for a review history longer than 12 months.
What happens if my installer goes bust? Manufacturer warranties survive because they sit with the maker, provided the brand has an Australian office. The workmanship warranty usually dies with the company, which is why years in business belongs in your decision.
Should I get a battery now or later? The Cheaper Home Batteries Program has made now materially cheaper than pre-2025, and Mackay’s storm-prone summers make backup power useful. But a battery only pays if your evening usage supports it, so quote the system with and without one and compare paybacks.
How big a deposit is normal? Ten per cent or less is typical. Be cautious of anyone wanting most of the money before installation day, and never pay a large deposit to secure a “today only” price.
What are the red flags in a quote? No named panel, inverter or battery models. No SAA accreditation number. Pressure tactics and expiring discounts. Silence on the Ergon connection process or wind region C certification. Any one of these is reason enough to use another company.
