The Entry and Mid Tiers

27.96kWh is our most requested solar battery for this system, suited to a 5+ person household. 32.62kWh adds storage for a car charger overnight or higher daytime solar use across a high-consumption Queensland property.

The Larger Tiers

37.28kWh handles heavier evening loads a smaller battery struggles with, delivering near full-day backup for this solar system. 41.94kWh is our largest pairing, sized for a household wanting the strongest grid independence this system supports.

Which Solar Battery Suits Your Household?

A smaller tier keeps this solar system’s total lighter. A larger tier, like 41.94kWh, carries a high-usage household through heavier evening loads with less reliance on the grid. Panels and installation stay identical across every tier, so the difference reflects battery storage capacity, not build quality.

Solar Panels

Hybrid Inverter

Mounting & Racking

Installation and Commissioning

28 solar panels at 475W tier-1 monocrystalline give your solar system its full 13.3kW output, individually wired so shading on one panel doesn’t drag down the rest. A 10kW hybrid inverter converts that output into usable power and manages your battery’s charge and discharge cycle across every tier on this page. Mounting hardware is engineered for your specific roof and Queensland wind loading, so your solar system stays secure through storm season. Installation is completed by our own CEC-accredited team, including switchboard connection, full testing, and a compliance certificate for your records.

▽

Panels, inverter, and mounting stay identical across every battery tier of this solar system, backed by a 10-year workmanship warranty separate from manufacturer cover. Your household’s typical energy use determines the right battery, not the panel count, which is fixed for every 13.3kW system we install across Queensland. Ask about your usage and we’ll confirm the right battery and total figure for your address.

Answers to Common Questions About This 13.3kW Solar System with Battery

How much does a 13.3kW solar system with battery cost?

Every solar system is custom-quoted, so cost depends on your roof, your battery choice, and your household’s typical energy use, with the federal rebate already deducted from your figure. Most customers receive a firm, itemised quote within a few hours, assessed from satellite imagery of your roof rather than an in-person visit.

Which battery should I choose for this system?

It depends on your household size and evening electricity use. The 27.96kWh tier suits a smaller high-usage household. The 32.62kWh and 37.28kWh tiers suit a growing household, an EV charger, or higher daytime use. The 41.94kWh tier suits the largest households wanting maximum capacity and grid independence.

How much battery storage do I actually need?

This depends on how much electricity use you want covered overnight or during a blackout. Our four options for this 13.3kW solar system range from 27.96kWh to 41.94kWh, so we help you match battery size to your household rather than guessing.

Am I eligible for the federal rebate?

Most Queensland households qualify for the federal Cheaper Home Batteries Program on this 13.3kW solar system, applied as a point-of-sale discount, not a claim-back after installation. The QLD Battery Booster closed to new applications in 2024, so the federal program is the only scheme reflected in your quote today, whatever battery tier you choose.

What's included in a quote for this solar system?

Your quote covers 28 solar panels at 475W each, a 10kW hybrid inverter, mounting and racking rated for Queensland conditions, and full installation by our CEC-accredited team, plus your chosen battery. Every component is itemised, from panels through to grid connection.

How long does installation take?

A solar system and battery installed together usually takes 1 to 2 weeks once your quote is accepted. From enquiry to a firm quote is typically a few hours, and from acceptance to install day is about a week across Queensland.

▽

Do you install EV chargers alongside this system?

Yes. We install EV chargers alongside a new solar system, so you can charge your car from your own solar power rather than drawing extra electricity from the grid. This is an increasingly common request from households investing in a 13.3kW solar system.

What if my household needs a smaller system than this one?

If your household is smaller, or your daytime and evening electricity use is lighter, our 10.5kW or 6.6kW solar packages may suit your household better than this 13.3kW system. We also install commercial solar systems from 50kW paired with 50 to 100kWh of battery storage for businesses.

Is my roof suitable for a 13.3kW system?

Most homes with sufficient roof space suit this solar system. We assess your roof space, orientation, and shading using satellite imagery before confirming your panel layout, battery placement, and final quote.

What warranty comes with my panels, inverter, and battery?

Every battery carries a 10-year manufacturer warranty and is compatible with Queensland Virtual Power Plant programs. All installations are backed by a separate 10-year workmanship warranty, distinct from the manufacturer cover on your solar panels and inverter.

Are your installers accredited?

Yes. Our installation team is SAA and CEC accredited for both solar panel and battery installation, and every job follows Clean Energy Council and Solar Accreditation Australia safety guidelines.

Do you offer a price beat guarantee?

Yes. Find a genuinely better price on a comparable solar system and battery within 30 days, and we’ll beat it. Every price we quote already reflects current rebates, so you’re comparing real costs, not headline figures before rebates are applied.

What payment options do you offer?

We offer upfront payment, a standard deposit of $100 to $300, a zero-deposit payment plan, and financing on solar and battery packages. Whichever option you choose, your indicative price, current rebates, and installation timeline stay consistent.

Which brands do you install?

We carry a wide range of solar panel, inverter, and battery brands, including Fox ESS, GoodWe, Growatt, SigEnergy, Anker SOLIX, and Alpha ESS. You choose the combination that fits your household, with full datasheets for every panel and battery we offer.

Is my system compatible with Virtual Power Plant programs?

Yes. Every battery we install is VPP-ready and compatible with Queensland’s Virtual Power Plant programs, so your stored solar energy can support the grid and may earn additional credit where a VPP program operates in your area.

Do you handle the grid connection and paperwork?

Yes. We manage your STC application, grid connection, and compliance paperwork for every solar system we install, from your first quote through to handover. Your point of contact stays the same throughout.

Is there a minimum job size?

No. We don’t have a minimum system size or type we won’t quote, whether it’s this 13.3kW residential solar system, a smaller 6.6kW or 10.5kW package, or a commercial solar and battery installation.

How do I know what solar system size I need?

It depends on your household’s electricity usage, roof space, and budget. Our three residential packages, topping out with this 13.3kW system, cover most Queensland homes, and we recommend the right size using a satellite assessment of your roof and typical usage.

What's the difference between the 6.6kW, 10.5kW, and 13.3kW packages?

The difference is how much solar energy each system generates and how much battery storage pairs with it. This 13.3kW package is our largest residential option, suited to high-usage households, while the 6.6kW and 10.5kW packages suit smaller or mid-sized homes.

How is my system's cost affected by my roof?

Roof type, number of storeys, and any switchboard or meter box upgrades all affect your final cost. The distance between your inverter, your battery, and your main switch also plays a part, which is why every quote is calculated for your specific property.

Does GREON operate outside Queensland?

We currently focus on Queensland, from Brisbane and the Gold Coast up through Bundaberg, Rockhampton, Mackay, Townsville, and Cairns. We also reach customers in New South Wales, South Australia, and Western Australia through our contracted installer network.

What happens to my electricity bill after installation?

Your solar panels generate power during the day, and any surplus your battery doesn’t use gets exported to the grid under your retailer’s feed-in tariff. Most households see a meaningful drop in their electricity bill within the first billing cycle.

Can I upgrade my solar panels or battery capacity later?

Yes. Many households start with this 13.3kW solar system and add capacity later as their electricity needs grow, whether that means a bigger battery or an EV charger down the track.

How accurate is the satellite assessment compared to a site visit?

Our satellite imagery gives a highly reliable first estimate of your roof’s solar potential, panel count, and likely output. A technician confirms every detail on installation day, so any final adjustment to your indicative figure is minor and disclosed upfront.

What's the payback period on this solar system and battery?

Payback depends on your household’s energy use and the battery tier you choose, with the federal rebate lowering your cost from day one. For a well-positioned 13.3kW system with strong self-consumption, a payback period of 4 to 6 years is typical.

What Your 13.3kW Solar System with Battery Costs

Why Every Quote Is Custom

Every 13.3kW solar system here is custom-quoted for your home, not sold off a fixed figure like a solar panels catalogue item.

Your indicative figure depends on three things: your roof, your household’s average solar energy use, and the battery option you choose from our full range of solar batteries and solar power tiers. No two Queensland solar systems are priced the same way, even when they sit on the same street with the same 13kw solar system installed and the same energy storage backup running behind it.

What Affects Your Figure

Storage is the biggest single factor in what you pay for this 13kw solar system and its battery. The 27.96kWh, 32.62kWh, 37.28kWh, and 41.94kWh options sit at different kWh tiers, so the figure rises with size, not with the solar panel itself.

Your figure also depends on your roof type, number of storeys, and any switchboard or meter box work needed before work begins across Brisbane and the rest of Queensland, Australia.

Solar panels and the panel count stay the same across every tier of your 13kw solar battery pairing, and the same solar inverter powers every solar system. The difference reflects battery capacity alone, not the standard of installation work or the electricity your solar system ultimately generates for the whole system.

Getting Your Exact Figure

Most customers receive a firm, itemised figure within a few hours, assessed from satellite imagery of your roof and your home’s typical use. No in-person visit is required to get your 13kw system started. Free, no-obligation, and covering your full 13.3kW solar system: the panel count, the solar inverter, your chosen battery, and installation, all itemised as separate line items so nothing about your energy costs is hidden in one lump sum figure.

Ask about financing or our zero-deposit payment plan, and we’ll model your total electricity cost against your typical household power bill before your solar system goes live across battery systems. Battery size and the current rebate are the two figures that move your final battery figure the most, so compare every solar battery price option carefully before you lock in your 13kW solar system battery pairing for what your household genuinely needs, backed by real energy figures from day one and confirmed against average battery prices across Australia for your address and household.

Rebates and Guarantees

Every battery storage option qualifies for the federal Cheaper Home Batteries Program, reducing your total system cost before you pay a cent toward your battery, whatever kWh tier you choose on this page.

We also back every 13kw solar battery installation with a 30-day price beat guarantee. Find a genuinely better figure on a comparable solar system and inverter within 30 days across Brisbane, Queensland, or the rest of Australia, and we’ll beat it, whatever tier and kWh you choose.

Cheaper Home Batteries Program, Applied to This 13.3kW Solar System

Every battery paired with your solar system qualifies for the federal Cheaper Home Batteries Program, applied as a point-of-sale discount on your solar system invoice, not a claim-back after solar installation.

▽

How the Discount Works

The figure is calculated per unit of usable battery storage, with a full-rate power band, a reduced-rate band, and a smaller band above that, tapering out for very large solar systems. Our CEC-accredited installers generate the certificate and apply the discount directly to your inverter and 13kw solar system quote, so the price already has it built in.

What This Means for Your Battery

The smallest 27.96kWh tier sits inside the full-rate band, so this solar battery attracts the strongest discount of any option paired with this exact 13kw solar battery system. The 32.62kWh, 37.28kWh, and 41.94kWh tiers each cross into the reduced band, so a larger battery still costs more for your solar system overall even with a bigger discount applied to your final battery price and total electricity cost. There’s no means test on this scheme: every Queensland household qualifies for backup support, whatever your solar panels or energy use.

The QLD Scheme Is Closed, the Federal One Isn't

The QLD Battery Booster closed to new applications in 2024, with no state-level replacement announced since. This federal program is the only active discount reflected in your figure today, across every solar panel and battery combination we install throughout Queensland and the rest of Australia, on every 13kw system we build. Ask us how rebates apply to installation timing for your specific 13kw solar battery system. Ask us and we’ll confirm the exact figure for your chosen battery, roof, panels, and household’s typical energy use and electricity cost across your 13kw solar system. Households across Queensland increasingly weigh this discount against solar panel output when picking a battery size for their solar system. The inverter and workmanship stay the same across every tier of this kWh range, so the discount and your chosen capacity move your average power bill down over storage time, wherever you sit on the grid. Larger solar options above the standard range see a smaller rebate per kWh of storage, which is why most homes choose a mid-range battery over the largest. This narrows the gap between solar systems, making a bigger battery a smaller step for your solar system, in real solar terms, than the figure alone suggests, backed by energy figures for every kWh and household across Australia.

Why a 13.3kW Solar System Suits Your Household

A 13.3kW solar system is our largest residential package, built for a specific kind of home: 5 or more people, a high-usage roof, and daily electricity draw well above the average Queensland household.

Getting a Straight Answer on Sizing

Not sure this is the right fit for your home? We’ll assess your roof, your typical solar energy use, and your daily draw, then confirm the right panels and battery for your address, with an indicative solar battery price included across Australia.

▽

Household Size and Daily Usage

If your household runs 5 or more people through a normal day, with an electric vehicle, a pool pump, or ducted air conditioning running most evenings, this 13.3kW solar system and battery covers most of that load without oversizing your roof or your budget. It’s what most high-usage Queensland homes step up to once a 10.5kW solar system falls short of their daily energy needs.

When a Smaller Solar System Might Suit You Better

If your household is smaller, or your daytime and evening electricity use is lighter, this 13.3kW solar system may be more capacity than you need right now. Our 6.6kW or 10.5kW solar systems often suit 2 to 5 person households better, at a lighter upfront cost and a shorter payback period for that household’s typical use.

Your Battery Still Scales With You

Even at this panel count, you choose from 4 battery storage capacities, so your battery storage can grow with your household’s electricity needs even if your solar panels and inverter stay fixed. A smaller battery tier suits a lighter quote and quicker solar installation; a larger 13kw solar battery pairing suits heavier evening backup and future EV charging, with the same federal rebate applied across every kWh of battery we install throughout Queensland and Australia, whatever your household genuinely needs from its energy plan.
