Are you tired of opening huge power bills every three months? If you live in Western Australia, making your own energy is the best way to stop paying high electricity costs. A large solar setup is the perfect fix. When you pair a big 10kW solar system with a good home battery, you gain the freedom to power your house day and night using clean energy.
Before you buy a system, you need to know what you should be paying. You also need to know which parts are the most reliable. In this helpful guide, we will break down the current prices in easy terms. We will look at the newest government rebates and help you find the best 10kw solar system with battery price for your home.
Why a 10kw Solar and Battery Package is Perfect for Perth
Perth’s amazing sunshine makes it perfect for solar, but modern families using large air conditioners, electric cars, and pool pumps need more than a small setup. A large 10kW system generates about 40 units of power on a sunny day, easily covering your heavy daytime energy use while leaving lots of extra power to fill a home battery.
Upgrading to a full 10kw solar and battery package makes perfect financial sense. Because the grid pays very little for your extra daytime power, it is much smarter to store that energy yourself. This lets you use your own free power at night, helping you completely avoid high evening electricity prices.
Breaking Down the Average 10kw Solar Battery Price Perth
Wondering how much is a 10kw solar system with battery in 2026? While the solar panels alone usually cost between $8,000 and $11,000, a complete 10kw solar and battery package will cost between $13,500 and $20,000 fully installed in Perth, after all federal discounts and local state rebates are applied.
Where your exact quote lands in that 10kw solar battery price perth range depends on a few important things:
- Quality of Parts: If you choose basic panels and a basic inverter, your price will be lower. If you want top tier parts with very long warranties, the price will be higher.
- Your Roof Shape: Installing panels on a flat, simple metal roof is fast and cheap. If your roof is very steep, has old tiles, or is two storeys high, the labour costs will go up.
- Battery Storage Size: A standard 10kWh battery costs less than a huge 13.5kWh or 16kWh premium battery model.
- Electrical Box Upgrades: Some older houses in Perth need a new electrical switchboard before they can safely run a big 10kW system.
At SolarXcellence, we believe in clear and honest pricing. We make sure you get the absolute best 10kw solar system with battery price without any hidden extra fees at the end.
Saving Money: How the Solar Rebate WA Works in 2026
To help lower the high starting costs, homeowners in Western Australia can use excellent government incentives in 2026. Knowing how the solar rebate WA works is the secret to getting the best possible price for your new solar setup.
The Federal Panel Discount
The national government gives a discount based on special certificates. For a 10kW solar system put on a Perth roof in 2026, this federal discount is worth about $2,600 to $2,750. This discount drops a little bit on the first day of January every year. This means installing your system sooner gets you a better discount. Your solar team will take this money straight off your final bill.
The State Battery Rebate
The state government wants to help more families store their own power. The local solar rebate WA applies to home batteries. The exact amount of money you get back depends on your power company.
If you are a Synergy customer, you can get a rebate of up to $1,300 off the cost of a brand new battery. If you live further out and are a Horizon customer, you might get a higher rebate of up to $3,800.
To get this battery rebate, you must buy an approved battery model. You must also use a proper accredited solar installer. Finally, you have to agree to connect your battery to a Virtual Power Plant. This allows the local power grid to sometimes share your extra stored power to keep the whole city grid stable on very hot days.
What Size Battery for 10kw Solar System?
When wondering what size battery for 10kw solar system is best, most Perth families choose a 10kWh to 14kWh capacity. This size perfectly stores your excess daytime solar power to run your household appliances all night long.
A bigger battery is not always better. A massive 20kWh unit costs more upfront and might not fully charge during cloudy winter days. To avoid overspending on storage you cannot use, our SolarXcellence team will review your past power bills to find the perfect fit for your home.
Which Solar Battery is Best in Australia?
There are many battery brands for sale today. This leaves homeowners confused about which solar battery is best in australia for their own house. When picking a battery, you need to look at how much power it holds and if it works with the local power grid rebates.
In 2026, the best battery choices for Australian homes include:
- Tesla Powerwall 3: This is a very famous brand. It looks great on the wall, has amazing smart features, and is excellent at keeping your home running during a blackout.
- Sungrow: This is a huge brand in the solar world. Sungrow batteries offer brilliant value for money. They perform very well in the hot Australian sun.
- Alpha ESS: These batteries are known for being very reliable. They also have a clever design that lets you add more battery boxes later if your family needs more power.
- SAJ Batteries: This is another great option that saves you money while still working perfectly for normal family homes.
The “best” battery depends totally on your set budget and if you need special blackout protection features.
Beating High Evening Power Prices
Many homes in Perth are on special power plans that charge you at different times of the day. If you are on a plan like this, grid power prices become very expensive in the late afternoon and evening.
This is exactly where a 10kw solar and battery package shows its true value. As the sun sets and the expensive power rates start, your smart solar system switches your home over to run on the battery. You completely skip paying those high evening prices. Because you stop buying expensive power, your solar setup pays for itself much faster.

Frequently Asked Questions (FAQs)
How much is a 10kw solar system with battery?
A complete 10kw solar and battery package in Perth will cost between $13,500 and $20,000 in 2026. The final price depends on the quality of the solar panels, the size of the battery, and how hard your roof is to work on. This price range includes the federal discounts and local state battery rebates.
What size battery for 10kw solar system?
Most Perth homes will need a battery sized between 10kWh and 14kWh for a 10kW solar system. This size is great because it stores enough daylight solar power to run your household items through the night. Buying a battery that is too big will cost you extra money without giving you any added benefit.
Which solar battery is best in australia?
The best solar battery for your home will depend on your budget and power needs. The top choices in 2026 are the Tesla Powerwall 3, Sungrow, and Alpha ESS. These brands are highly rated for Perth homes because they offer great warranties, handle hot weather well, and link up with local power grids.
Is the solar rebate WA still running in 2026?
Yes, Perth homeowners can still use great government rebates in 2026. You get a federal discount of about $2,600 for solar panels. Also, the state battery rebate gives Synergy customers up to $1,300 off a new battery. Regional Horizon customers might even get up to $3,800 to help lower the cost.
Can a 10kw solar system with battery backup run everything?
A 10kw solar system with battery backup can run your basic home items during a blackout. This includes your lights, fridge, internet, and a few power points. It is not meant to run heavy things like big, ducted air conditioners or pool pumps at the same time, as this drains the battery very quickly.
How long does it take to pay off a 10kw solar system?
Most Perth families can pay off their 10kW solar and battery package in about six to eight years. Because power prices from the grid keep going up, using your own stored solar power saves you a lot of money every day. Using less grid power at night is the best way to pay off your system very fast.
Do I need special power connections for a 10kW system?
To get the most out of a 10kW solar system, it is best to have three-phase power at your house. If you only have standard single-phase power, the grid rules might limit how much power your inverter can send back to the grid. A home battery fixes this by storing that extra power for you to use later.
Conclusion
Putting a large solar and battery system on your home is no longer just a good idea for the planet. It is a vital choice for your family budget. By finding the best 10kw solar system with battery price, you can protect your home from nasty power price rises forever.
