Stirling is the suburb that lends its name to the City of Stirling, a well-established residential belt threaded between the Mitchell Freeway and Main Street and served by its own train station. It’s a mature, stable area — the median age is 42, more than four in five of its 3,618 homes are owner-occupied, and 43.7% are owned outright, a sign of long-tenure households with the certainty to invest in a 25-year asset. Rooftops here are predominantly generous, detached and freestanding (about 87% are separate houses), giving installers clean, unshaded roof planes to work with. That shows in the local numbers: across the 6021 postcode the average installed system size runs to 6.4 kW — noticeably above the Perth norm — which tells you households here are sizing up rather than fitting the bare minimum. With Perth’s strong sun, that scale of system generates well over 10,000 kWh a year.

With mostly large detached homes and long-term owners, Stirling suits a proper system rather than an entry-level one. A 6.6 kW array — around 16 panels — is the common starting point and generates roughly 9,500–10,500 kWh a year, but the 6.4 kW postcode average shows plenty of households are going bigger. If your home runs ducted air-conditioning, a pool or works-from-home loads, 10 kW is often the smarter buy, landing near $5,500–$8,500 after the STC rebate. Just remember Western Power’s export rules: above 5 kW your feed-in is capped at 1.5 kW or 5%, so a bigger system earns its keep only when you self-consume or store the surplus. For many established Stirling owners, adding a battery under the WA Residential Battery Scheme is the logical next step.
Rooftop solar on a standard non-heritage home in City of Stirling 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.
Many Stirling homes have tile roofs and original 1970s–1990s switchboards. We verify switchboard capacity, check tile condition before mounting, and replace any deteriorated tiles during install rather than discovering issues afterwards.
In most cases no. WA’s Planning and Development Regulations (Schedule 2, clause 61) exempt roof-parallel solar on non-heritage homes from development approval, so no City of Stirling application is usually needed. Older or character-listed properties can be exceptions, and a building permit may still apply.
Roomy older roofs here easily take 6.6 to 10 kW. Across postcode 6021 the average is already 6.4 kW, well above the metro norm. Western Power export-limits anything over 5 kW, and from 1 May 2026 systems up to 30 kVA will be allowed with Emergency Solar Management.
Most will. On homes of this vintage we check rafter condition, tile or Colorbond integrity and switchboard capacity before mounting. Many established switchboards need a minor upgrade or a new isolator to meet current standards — we assess this during the site inspection and quote it upfront.
A typical 6.6 kW system comes down to about $3,000–$5,000 installed once the STC rebate (around $2,500–$3,500 in Perth’s Zone 3) is applied. A larger 10 kW system, popular on Stirling’s bigger homes, generally runs $5,500–$8,500 fitted.
It’s increasingly worthwhile. With exports above 5 kW capped by Western Power, a battery lets you use your own daytime solar at night instead of buying it back. The WA Residential Battery Scheme’s rebates and no-interest loans have made upfront storage far more affordable.
Most Perth households save $1,500–$2,500 or more a year with a correctly sized system. In Stirling, where homes are large and daytime consumption is high, well-matched solar — especially paired with storage — often sits at the upper end of that range.
