Mullaloo is a relaxed beachside suburb in the City of Joondalup, wrapped around Mullaloo Beach and Tom Simpson Park and popular with established families. The housing reflects that stability — the ABS records around 2,125 dwellings, 94.8% of them separate houses, with 84.5% owner-occupied and a median age of 41. Household incomes sit comfortably around $2,447 a week, and many of these homes come with the energy appetite you’d expect near the coast: reverse-cycle air-conditioning running through summer, pool pumps, and increasingly an EV in the driveway. Across the wider 6027 postcode area — which covers several suburbs including Mullaloo, Ocean Reef and Beldon — homeowners have installed more than 10,000 solar systems, a strong signal of local confidence. With generous north-facing roof space on most homes and solar generally approval-exempt on non-heritage properties (Schedule 2 clause 61), Mullaloo is well suited to a system sized for real family consumption rather than the bare minimum.

While 6.6 kW (about 16 panels, generating 9,500–10,500 kWh a year in Perth) remains the entry point, Mullaloo’s larger family homes often justify stepping up. A pool, ducted cooling and an electric vehicle can easily push a household past what a 6.6 kW array covers, making a 10 kW system — roughly $5,500–$8,500 after the STC rebate — the smarter long-term choice. A 6.6 kW system, by comparison, typically costs $3,000–$5,000 installed. Batteries are an obvious next step for this profile: coastal homes use a lot of power in the evening, and storing surplus solar rather than exporting it (Western Power caps exports above 5 kW anyway) protects you from peak tariffs. The WA Residential Battery Scheme’s rebates and no-interest loans make storage far more compelling than even a year ago. We’ll always specify salt-rated, high-quality components given the coastal location.
Rooftop solar on a standard non-heritage home in City of Joondalup is generally exempt from planning approval when panels sit parallel to the roof — a building permit may still apply. The federal STC rebate discounts your system upfront based on size and Perth’s Zone 3 rating, and the WA Residential Battery Scheme adds rebates and no-interest loans for home storage. On the network, Western Power export-limits systems over 5 kW (to the greater of 1.5 kW or 5% of inverter capacity) and requires Emergency Solar Management; since 1 May 2026, inverter capacity up to 30 kVA is permitted under those rules.
Properties in Mullaloo sit close to the coast, so we recommend marine-grade mounting hardware, sealed roof penetrations, and inverter placement that avoids direct salt-spray exposure. Panel manufacturers vary in their salt-mist corrosion ratings — we specify panels rated to IEC 61701 Severity 6.
Generally no. Under WA regulations (Schedule 2, cl.61), panels mounted parallel to a non-heritage roof are usually exempt from development approval, though a building permit can still apply. The City of Joondalup can confirm the requirements for your particular property before installation.
Most local roofs suit systems around the 5.21 kW postcode-area average. Beyond 5 kW, Western Power applies export limiting — the greater of 1.5 kW or 5% of inverter capacity — so we balance array size against your usage and, often, a battery for evening coastal living.
Yes. Within a few kilometres of the coast, salt spray corrodes standard fittings faster, so we use marine-grade rails, stainless steel fasteners and coastal-rated panels and inverters. It’s a small upfront difference that protects your system’s lifespan against the Mullaloo sea air.
Expect around $3,000–$5,000 installed for a 6.6 kW system once the STC rebate (about $2,500–$3,500 in Perth’s Zone 3) is deducted. Because many Mullaloo homes go with 10 kW, budget closer to $5,500–$8,500 after the same incentive for the larger size.
If your household draws power into the evening — common with pools and air-conditioning — a battery captures daytime solar you’d otherwise export cheaply. Combined with the WA Residential Battery Scheme’s rebate and no-interest loan, the payback period is now realistic for most Mullaloo owner-occupiers planning to stay put.
Most correctly sized Perth systems save $1,500–$2,500+ annually. Larger family homes with high daytime and evening use tend to sit at the top of that band, and adding a battery to sidestep the evening peak can lift the figure further.
