What a 10kW system gives you
A 10kW system makes enough spare daytime power to run a busy household and charge a decent battery for the evening.

Room for a battery, air con and an EV
With 10kW of panels there’s usually spare solar in the middle of the day. A battery stores it for the evening, so you buy far less power at night.

EstimatePrices are conservative starting estimates for installs in 2026. They include GST and the federal solar and battery discounts, and are not a quote. Battery discounts change over time. Your quote may include extras such as switchboard upgrades, racking for tricky roofs, a new or upgraded inverter, optimisers for shading, blackout backup wiring or three-phase work. Your price is confirmed after your free Energy Assessment.
Estimates include GST and the federal solar rebate (STCs) and, with a battery, the federal Cheaper Home Batteries discount, for installs in 2026. Your written quote can change with your roof, switchboard, inverter choice, battery brand, backup wiring or three-phase power. Average output uses Clean Energy Council figures of 3.5 to 4.4kWh per kW a day.
Battery or no battery
When to consider a battery with 10kW solar
Solar makes power in the day. A battery stores what you don’t use so you can run the house at night instead of buying power back from the grid.
A battery is worth a look if
Most of your power is used after dark: cooking, air con, TV and hot water in the evening.
Your feed-in tariff is low. In regional Queensland the regulated rate is 6.006c per kWh from 1 July 2026 (Queensland Competition Authority), and buying power back at night costs several times that.
You want backup in an outage. This needs a backup-capable inverter and wiring, and what stays on depends on the equipment.
You want the federal battery rebate before it steps down on 1 January 2027.
It may not pay yet if
Someone is home using power through the day, so most of your solar is already used as it’s made.
Your bill is already small after solar.
Your roof can’t fit enough panels to fill the battery in winter.
Adding a battery does not make a home off-grid. Off-grid needs a larger system designed for it.

Nexus Solar was not the cheapest option, but Peace of Mind during the process with Troy and the Professional Service and Product proved well worth it, especially the Back-Up.

... it has minimized my power bill by more then half ... Would say a battery would be great help due to using more power at night when people are home
Auzzie W. ★★★★★Solar customer · Google review
... we are very impressed that we have now ordered a battery as well to add to our solar set up ... Special thanks for being able to work in regional areas of WA as well.

It was only about 2 weeks from the 1st phone call to the panels being put onto the house, very quick and easy process. I should have done it years ago.

I had a 13.3kW solar system with a 32kW GoodWe battery installed in Emerald a few years ago, and I’ve been extremely happy with the results. I was born in Mount Isa and later moved to Emerald, so I understand how important it is to have a reliable and efficient energy setup in regional Queensland. Before installing solar, my electricity bills were through the roof — around $1,500 per quarter. Since having the system installed, my bills have dropped to almost the minimum charge, which has made a huge difference. From the initial consultation through to installation, everything was handled professionally, efficiently and with great attention to detail. The team were knowledgeable, friendly and easy to deal with, and the workmanship was excellent. A great investment, a great result, and one of the best decisions I’ve made for my home. I’d happily recommend this company to anyone considering solar and battery storage.

We recently had our solar system installed by Nexa Solar at our home and couldn't be happier with the experience. The whole team was highly professional, friendly and easy to deal with from start to finish. The installation was very neat and everything was explained clearly. Great communication and excellent service throughout. Would definitely recommend Nexa Solar to anyone considering solar.
Susanne Pritchard
I would recommend this firm to anyone. They made getting my Solar Battery so easy. Mike was very in-depth with his knowledge of Solar. Kelly from the office couldn't have been more helpful and the installers guided is through how to use it. We are very happy with Nexa Solar
Helen Murdoch
Very happy with the recent installation of both panels & battery. Ellie was great organising the actual installation and nothing was ever too much trouble. The actual Install team were terrific. Once again nothing was too much trouble and he answered all my questions and showed me the app. Thank you. Regards Helen Murdoch

The tradies that installed my system they were respectful and polite. On completion they left the site clean and tidy. They worked like trohans all day.
Robyn Kildey
Fast service from enquiry to quote and sales to fitting within 2 weeks. Very knowledgeable both fitters and sales. Price even with rebate was a lot but good quality can't be cheap and great customer support, constant phone calls with updates and fitting times and even refund for panels they couldn't fit. Eventually it will pay for itself so I'm happy

Rebates step down on 1 January 2027
The federal solar rebate drops by about a fifth and the battery rebate by about 16% from 1 January 2027. Your install date is what counts, not the date you sign.
Our estimate starts from $8,490 Estimate for a 10.36kW system, including GST and the federal solar rebate (STCs), on a standard install. Three-phase upgrades, a switchboard upgrade, a premium inverter or a complex roof add to it. Your Energy Assessment gives you a written quote first.
How much is a 10kW solar system with a battery?
10.36kW of solar with a 16kWh battery is estimated from $18,990 Estimate, including the federal solar and battery rebates. Add a home EV charger and it’s from $20,490 Estimate.
How much does a 10kWh battery cost on its own?
If you already have solar, adding a 10kWh battery is estimated from $7,390 Estimate after the federal battery rebate. For a 10kW system we usually pair a bigger battery, around 16kWh, estimated from $11,390 Estimate on its own.
How many panels are in a 10kW system?
Usually 24 to 28. Our 10.36kW package comes to 28 panels at 370W; with 415W panels it’s 25 and with 440W panels about 24.
How much power does a 10kW system produce?
Averaged over a year, roughly 36 to 46kWh a day. The Clean Energy Council puts average daily output at 3.5kWh per kW installed in Hobart, 4.2 in Brisbane and Cairns and 4.4 in Perth. Summer days produce more and winter days less.
Do I need three-phase power for a 10kW system?
Not always. Many single-phase homes can have 10kW of panels, but networks set limits on inverter size and exports, and these vary by area. Three-phase homes generally have more room. We check your connection and the network rules in the Energy Assessment.
Is 10kW too big for my home?
Not if you use a lot of power, plan to add a battery or an electric vehicle, or run air con and a pool. If your bill is modest and you’re home in the day, a 6.6kW system may be enough. We size it from your actual bill.
What size battery suits a 10kW system?
Around 16kWh is a common match, because 10kW of panels can usually refill it on a normal day. Bigger is possible if your evening use is high. Adding a battery does not make a home off-grid.
How much does a 10kW system cost per kW?
Our 10.36kW estimate works out at about $820 per kW installed, after the federal rebate, similar to our other sizes. Pick the size that matches your use.
What rebates apply to a 10kW system?
The federal solar rebate (STCs) is already taken off our estimates. Batteries also get the federal Cheaper Home Batteries discount. Both step down on 1 January 2027 and the install date is what counts. Check what you can claim.
Will a 10kW system keep my power on in a blackout?
Not on its own. Grid-connected solar switches off in an outage so line workers stay safe. For backup you need a battery with a backup-capable inverter and the right wiring, and what stays on depends on that equipment.
Can a 10kW system take my home off-grid?
Not on its own, and adding a battery doesn’t make a home off-grid either. Going fully off-grid needs a system designed for it, with more storage and usually a generator. Talk to us about batteries and off-grid.
How long does installation take?
Most home installs are done in a day. Several of our customers were installed within one to three weeks of their first call. Network approval times vary by area, and we handle the paperwork with your network for you.
Do you install in my area?
We have local consultants and crews across regional Queensland and in New South Wales, Western Australia and Tasmania, and we can often help other areas with a phone consultation. See every area we service.
What is the free Energy Assessment?
It starts with a call to go through your power bill and any existing solar. If it suits, a local consultant visits to check your roof, shading and switchboard. You get a tailored recommendation and a written quote, with no obligation.
