Start slashing your energy costs with your own array of solar panels.
Residential Solar Systems Perth
Perth gets more usable sunshine than almost any capital city in the country, which makes a home without solar one of the easier money-leaks to fix. The question for most households is no longer whether to install residential solar panels, but what size system makes sense and how quickly it pays for itself.
We are a Perth-based, family run and operated solar business, and we have been helping local homes generate their own power for years. This page covers the system sizes we install, what you will actually save, the 2026 rebates, and how the whole process works.
Why Solar Stacks Up for Perth Homes Right Now
Grid power is expensive, and the gap between what you pay to buy it and what you earn selling it back has only widened.
On Synergy’s A1 home tariff you pay about 32.37 cents per kWh, as at May 2026. Under the Distributed Energy Buyback Scheme, Synergy (2026) pays you 10 cents per kWh for power you export between 3pm and 9pm, and 2 cents at other times. That difference is the whole game. The savings come from using your own solar in your own home, not from exporting it cheaply.
So a well-sized system is one that covers as much of your daytime usage as possible, then channels the surplus toward the loads that matter. If your evenings are heavy, that is where a battery earns its place. If your daytime use is high, simply running more of the house on solar while the sun is up does the work.
Types of Solar Power Systems for Your Home
Depending on your home and power usage you might opt for a different sized system. The most common residential solar system is definitely the 6.6kW system covering a large party of your daily solar consumption while still enabling you to sell your excess power back to the system.
6.6kW Solar Power System
The most popular solar-powered system for most homes.
Depending on your daily energy usage we find our customers’ panels pay for themselves in 3-5 years’ time.
7.7kW Solar Power System
Perfect for the larger household, as well as commercial businesses.
Your roof will require a fair bit of additional space.
10.38kW Solar Power System
Designed for those higher power consumers, home businesses, and those who love their spa.
13.28kW Solar Power System
Perhaps unnecessary for the typical residential home, however depending on your energy needs, it’s always better to get a slightly bigger system than you require.
Types of Home Solar System We Install
The right system size depends on your roof, your budget and how much power you use. These are the configurations most Perth homes choose.
System size: 6.6kW
Most homes, average usage
Modest
The most popular residential size. Covers a large share of typical daytime use and still exports a surplus.
System size: 10kW
Larger homes, higher usage, pools
More space needed
A strong match for higher daytime consumption or a future battery.
System size: 13.3kW and above
High consumers, home businesses, EV charging
Generous
Sized for heavy users. Worth slightly oversizing if your usage is set to grow.
A common rule of thumb is that it is better to slightly oversize than to undersize, because adding capacity later costs more than building it in now. We confirm the exact panel count and layout when we assess your roof.

How Installation Works
Putting solar on your home is straightforward, and we plan it so your system captures the most sun every day.
First, we visit to assess your roof, shading and household usage, then quote a system that fits. On installation day we confirm the placement of your panels and inverter, checking for shade and orientation issues that affect output. We set aside a full day for mounting, installation, testing and commissioning. Once it is live, we connect your system to your WiFi and show you how to read it, including the app if you have opted in. After that, we provide ongoing monitoring and support for the life of the system.
Get More Out of Every Panel
A panel does its best work when the power it makes is used on site rather than sold back at a few cents.
That is the thinking behind the Solar AC DC range we fit as the WA distributor: hybrid air conditioning and solar hot water that run directly off their own panels during the day and fall back to mains only when needed. For homes that want to push self-consumption further without a storage battery, running your hungriest appliances straight off the sun is a genuine option, and the panel STCs help offset the cost of those panels too. Ask us about it when we quote your system.
Common Questions Before You Commit
Is the upfront cost worth it? The rebate takes a meaningful slice off the price immediately, and from day one you are buying less power at 32 cents and relying less on the grid. The faster your usage shifts to daytime or to a battery, the faster it pays back.
Will it work on a cloudy or shaded roof? Panels still generate in overcast weather, just at reduced output. Shade is the bigger issue, because panels are wired so one shaded panel can drag down others. Where shading is unavoidable, we use microinverters or optimisers so the rest of the array keeps performing. We check all of this before we quote.
Can I trust the installer? We are a local family-run business based in West Perth, and your system is fulfilled by Min Solar, a Western Australian, Australian owned and operated company. The work is done by accredited installers, and we are here for the life of the system, not just the install day.

Frequently Asked Questions About Residential Solar
We get a lot of calls and customers tend to ask similar questions. Here we hope to answer some of yours.
How much power does a 6.6 kW solar system produce in Perth?
The amount of power that a 6.6 kW solar system produces in Perth, Western Australia, will vary depending on several factors such as the location, orientation, and tilt of the solar panels. However, on average, a 6.6 kW solar system in Perth can produce around 25-30 kilowatt-hours (kWh) of electricity per day, depending on the amount of sunlight it receives. This can provide a significant portion of a typical household’s electricity needs, reducing their dependence on the grid and saving them money on their electricity bills.
How much can you save on your power bill when you have solar?
The amount you can save on your power bill by having solar panels depends on several factors such as the size of your solar system, your electricity consumption, the cost of electricity from your utility company, your location and climate, and your solar system’s efficiency. On average, homeowners can save 30-50% on their electricity bill by going solar. However, the exact savings can vary and it’s best to get a personalized assessment from a solar professional to determine the potential savings for your specific situation.
Do solar panels work during cloudy weather?
Solar panels can still generate some electricity during cloudy weather, although the output will be significantly lower compared to sunny conditions.
This is because clouds can reduce the amount of sunlight that reaches the solar panels. However, most solar panels are still able to produce some electricity even on overcast days.
Is shade a problem for solar panels?
Yes, shade can be a problem for solar panels. Even a small amount of shading on a portion of a solar panel can significantly reduce its overall output.
This is because solar panels are designed to work in series, meaning that the performance of each panel is linked to the performance of the others. When one panel is shaded, it can lower the output of the entire system.
To maximize the efficiency and performance of a solar panel system, it’s important to make sure that the panels are installed in a location that is free from shading from buildings, trees, or other obstructions.
If shading is unavoidable, it may be necessary to use technologies such as microinverters or optimizers that can help mitigate its effects.
