Solar System Installation in Mackay
Solar panels in Mackay face conditions that a southern city installation never deals with. Cyclone season brings strong winds, the wet season brings heavy, humid months, and approval for grid export comes from Ergon Energy Network. Each of these affects which products suit your roof and how the system should be set up.
Greenlight Solar sells and installs solar panels, batteries and inverters for homes, farms and businesses across Mackay and the surrounding region. Share your recent power bills and a few details about your property. We’ll put forward products and a system size that suit how your household or business actually uses electricity.
Finding the Right Solar System Size in Mackay
Two Mackay homes on the same street can need very different systems. We look at:
- your bills, especially how much power you use after dark
- roof size, pitch and direction, and any shading
- whether you have single-phase or three-phase supply, which affects export limits on the Ergon network
- battery plans, whether now or a few years away
- loads you expect to add, such as an EV, a pool or heat pump hot water
- air conditioning, which often drives summer usage in Mackay
A shift worker who sleeps through the day and runs air conditioning in the afternoon uses power differently from a family that’s out from morning to evening. Find out more about solar for your home.
Local Conditions That Affect Solar in Mackay
Cyclonic wind loads.
Mackay sits within the cyclone-affected stretch of the Queensland coast. That makes the mounting system as important as the panels. Rails, clamps and roof fixings need to be rated for the wind conditions at your address. When comparing quotes, ask for documentation showing the racking suits your site.
Tropical heat and humidity.
Long, hot summers raise roof temperatures and reduce panel output. Humidity and heavy rain also test outdoor electrical equipment, so IP ratings and mounting locations for inverters and batteries deserve attention.
Coastal suburbs.
Homes in Bucasia, Shoal Point, Eimeo, Blacks Beach and Slade Point sit closer to salt air than homes in Walkerston or Rural View. Manufacturers set their own rules for installations near the sea. We check those rules for the products you’re considering before we quote.
Ergon export settings.
Ergon Energy Network decides how much power your system may feed into the grid. The limit depends on your phase supply, the network near your home and your connection. Dynamic export arrangements may be available in some areas, but they need a compatible inverter and Ergon’s approval.
Commercial and Farm Solar in Mackay
Mackay’s economy runs on daytime work, which matches when solar produces power. Strong candidates include:
- workshops and mining services businesses in Paget
- retail stores and offices
- medical practices
- accommodation providers
Cane farms around the district have their own patterns, with irrigation pumps, sheds and workshops driving demand.
A commercial quote considers:
- the site’s interval data and operating hours
- roof condition, structure and wind rating, including suitability for cyclonic loads
- three-phase supply, switchboard capacity and Ergon export limits
- whether batteries or EV chargers suit fleet or site needs
Business savings depend on tariff structure, operating patterns and the equipment chosen, so we don’t advertise a fixed return. Read more about our commercial solar systems.
Hot Water Heat Pumps and EV Chargers
Heating water is a big part of many household power bills. A heat pump set to run while your panels are producing can use your own solar for most of that job.
Options include the iStore hot water heat pump and the Emerald hot water heat pump. See our full range of heat pump options.
If you’re planning to buy an electric vehicle, ask about EV charging for your home as part of the same job.
Solar Battery Installation in Mackay
After a big storm or cyclone, power can take time to return. That makes backup a common reason Mackay households look at batteries. The other reason is value. Most regional Queensland homes buy power from Ergon Energy Retail, and what you earn for exported solar is usually well below what you pay for electricity at night. Storing daytime solar for evening use can make better use of your system.

Backup after storms. A battery only supplies power during a grid outage if the system includes the right backup hardware and wiring. Depending on the product, backup might cover the fridge, lights and a few power points, or the whole house. Some batteries don’t offer backup at all. If backup is your main reason for buying, say so up front so the quote reflects it.
Batteries for existing solar. Your current inverter, panels and switchboard determine how a battery can be added. Some homes can connect a battery as is. Others need extra equipment or a newer inverter. We look at your setup before recommending a battery.
Keeping batteries cool. Batteries have rated temperature ranges, and Mackay summers can push an exposed wall past them. Shade, airflow and shelter from wind-driven rain all help. The manufacturer’s installation rules set the limits.
Government Support for Solar and Batteries in Queensland
The main financial support available to Mackay households is federal. Each program has eligibility rules, and they can change over time.
Solar panels (STCs)
An eligible solar system qualifies for small-scale technology certificates under the Small-scale Renewable Energy Scheme. Installers usually take this value off the quoted price. The amount depends on system size, location and certificate market prices.
Batteries (Cheaper Home Batteries Program)
This program gives an upfront discount on eligible batteries paired with new or existing solar. The rate per kWh has fallen in six-month steps since 1 May 2026, and the discount tapers for usable capacity beyond 14 kWh. Our Cheaper Home Batteries guide explains the current settings.
State programs
Queensland’s former Battery Booster scheme stopped accepting applications in 2024. No separate state battery rebate is currently open for new installations.
Virtual power plants
Some energy retailers and battery brands offer VPP programs that use your battery to support the grid. What’s available depends on your retailer, battery model and location, so check the terms first.
Finance. Finance may be available to eligible customers, subject to assessment and approval.

Solar Panels We Install in Mackay
Panel choice in Mackay is about more than efficiency. Look at the panel’s mechanical load rating alongside the racking rating, especially in a cyclone-prone area. Also check how warranty terms treat coastal and tropical installations.
Higher-efficiency panels can make sense where roof space is tight. On a large, open roof, value per watt may matter more.
We supply and install:
Jinko solar modules, Trina Solar panels, SunPower modules, Aiko solar modules
You can also compare our solar panels side by side.
Solar Inverter Installation in Mackay
Your inverter turns solar output into usable household power. It also applies Ergon’s export settings and decides how easily a battery can be added later. Because inverters sit in Mackay’s heat and humidity, a well-ventilated, sheltered location helps them perform reliably.
There are three main types:
- String inverters suit simple roof layouts with steady sun across the day.
- Hybrid inverters can run solar panels and a compatible battery from one unit, which helps if storage is part of your plans.
- Microinverters work panel by panel, which can suit split roofs or roofs with patches of shade.
Inverter replacement. In older Mackay systems, the inverter often fails before the panels do. A replacement has to match your current array, string setup and supply phase. If you plan to add a battery later, a hybrid model may save a second upgrade, provided the battery you want is listed as compatible.
We supply and install Sungrow string and hybrid inverters, Solis solar inverters and Enphase inverter systems. Inverter and battery pairings are checked against manufacturer compatibility lists before installation. See all solar inverters we offer.

Solar Panels Coffs Harbour FAQs
Can a battery give me power after a cyclone or storm cuts the grid?
Only if the system includes backup capability. That requires a battery that supports backup, the right backup equipment and suitable wiring. Coverage can range from a few key circuits to the whole home. Some batteries provide no backup at all.
Who decides how much solar I can export in Mackay?
Ergon Energy Network sets the export limit for your connection. It depends on your phase supply and local network conditions. Dynamic export may allow more export at times in some areas, if your inverter is compatible and Ergon approves it.
Can I still get a battery rebate in Mackay?
There's no Queensland state battery rebate open for new installations. The federal Cheaper Home Batteries Program still offers an upfront discount on eligible batteries. The amount depends on the battery's usable capacity and when it's installed.
Should I upgrade my inverter when I add a battery?
It depends on your current inverter and the battery you choose. Some batteries come with their own inverter, while others need a compatible hybrid inverter. We check compatibility for the exact models before recommending an upgrade.
Is solar worth considering for a cane farm or mining services business?
It can be, especially where most power is used during daylight hours. The outcome depends on your load profile, tariff, roof or ground space, and Ergon's export settings for the site. A review of your interval data is a sensible first step.
Do I need approval from Mackay Regional Council for rooftop solar?
Many standard rooftop systems may not need a development approval where the applicable requirements are met. The installation must still comply with the relevant building and electrical standards, including wind loading. Heritage-listed and body corporate properties may also have extra conditions to check.
