Two Bullsbrook properties with the same size roof can need completely different solar systems. A new home in Kingsford, a rural-residential lot with a bore and a workshop, and an older house that already has panels each start with a different question.
Middle Swan Solar designs and installs solar panels in Bullsbrook from our office in Middle Swan, straight up Great Northern Highway. We work out how your property uses power and where the equipment should go before we recommend a single panel.
Newer homes in Kingsford and the townsite. Roofs are modern and installs are usually straightforward. The real question is the evening. If most of your power is used after 3pm, a bigger array alone will not fix your bill. We size for what you use now and leave room for a battery or EV charger later.
Rural-residential and acreage lots. Here the first question is where the load is. A bore pump, irrigation, a workshop compressor or a cool room can use more power than the house. That decides whether panels belong on the house or the shed, and whether your supply phase limits the design.
Homes that already have solar. Clean Energy Regulator data records 3,210 small-scale solar installations in the 6084 postcode since 2001. Many Bullsbrook owners are not buying a first system. They are deciding whether an ageing inverter is worth keeping, or whether a battery will work with what they have.
A big north-facing shed roof looks like the obvious place for panels, and often it is. But the roof is the easy part. Before we recommend it, we check four things:
Your supply phase shapes the inverter you can use and how much you can send to the grid. Many newer estate homes are single-phase. Some rural lots and workshops have three-phase. We confirm yours at the switchboard rather than guess from a bill.
Quotes get confusing because four different numbers describe one system:
From 1 May 2026, the export you get depends on your connection, Synergy’s requirements and whether your system stays online. We tell you the export figure for your site in writing, before you sign.
Synergy pays very little for solar exported in the middle of the day, so a battery makes sense when you use a lot of power in the evening. It makes less sense when the main daytime load is a pump that already soaks up your solar.
If backup during outages matters to you, it has to be designed in. A solar battery does not automatically run the house when the grid goes down. We ask which circuits must stay on, for how long, and whether the battery and inverter can actually start those loads. A bore pump’s start-up surge can be more than some battery systems can supply.
Eligible Synergy customers can get up to $1,300 off an approved battery under the WA Residential Battery Scheme, which requires joining a virtual power plant. Federal support is separate. See our WA battery rules guide and solar batteries page for current conditions.
Upgrades made from 1 May 2026 must meet the new connection rules. A like-for-like inverter replacement under warranty does not. If your system is underperforming, we test it first and tell you whether to repair it, replace the inverter, or add a battery to your existing solar.
Then we choose equipment to suit the site. Panels come from REC, Tindo, SunPower, REA and Aiko; inverters from Enphase, Fronius and SMA. Microinverters suit roofs split across several directions or partly shaded. A string inverter often suits one clean roof plane. Our microinverters vs string inverters guide explains the trade-off.
We answer all five in writing with every Bullsbrook quote.
Our systems start from around $8,000. Rural installs with long cable runs, trenching or switchboard upgrades cost more. Our Perth solar pricing guide breaks down what drives the price.
