Solar in Mandurah — What You Need to Know
Mandurah is WA's largest regional city, 74km south of Perth on the Mandurah Estuary — a city shaped by its extraordinary combination of inland waterways, ocean beaches, and a retiree demographic that has made it one of Australia's most solar-penetrated regional cities. The City of Mandurah's 'Solar for Seniors' program was funded through the state government's regional solar initiative and specifically targeted the suburb's high over-65 population, providing free energy assessments and access to 0% finance for eligible pensioners. The result is a city where retiree streets have higher solar adoption than working-family streets — a reversal of the national pattern — because the economic case was made directly to the demographic most motivated by fixed-income cost reduction. The Mandurah Estuary's extensive canal network means marine-grade hardware is essential for canal-front properties, while the broader city's inland streets use standard components. Perth's competitive installer market serves Mandurah actively, with dedicated businesses operating from the city.
