Solar in Mandurah

Mandurah's coastal location south of Perth provides excellent solar conditions with sea breezes keeping panels cool in summer. The area's growing population and predominantly single-storey housing make it well-suited to solar. Many Mandurah retirees are finding solar an effective way to reduce fixed living costs.

💡 Local Tip

Mandurah's canal and waterfront properties should use marine-grade mounting hardware. The humidity and salt air can accelerate corrosion on standard aluminium rails.

Mandurah Feed-in Tariffs

The current feed-in tariff in WA is approximately 2.5c/kWh for excess solar exported to the grid. With feed-in rates this low, maximising self-consumption (using solar during the day) is more valuable than exporting. A battery can help shift solar to evening use.

At current rates, a 6.6kW system in Mandurah exporting around 60–70% of generation would earn approximately $211/year in feed-in credits. The real savings come from self-consumption — every kWh you use directly saves 33c versus the 2.5c you'd earn exporting it.
