Perth home energy guide
What to check before accepting a solar quote in Perth
Compare the assumptions behind each quote, not just the headline price.
Solar quote checklist
- Compare proposed panel capacity (kW), inverter rating, equipment models and installation layout.
- Ask about roof orientation, shade, expected generation and the assumptions used.
- Check the total installed price, exclusions, warranties and workmanship support.
- Review your electricity bill for import tariffs, feed-in credits and daytime use.
- Check whether battery storage is included or optional, and whether backup power is actually supported.
- Confirm installer qualifications, required approvals and applicable incentive eligibility independently.
- Compare written quotes on equivalent assumptions and ask how future maintenance or replacement costs are handled.
Estimate payback with your own figures
Use the solar payback calculator to compare estimated generation, self-consumption and installation cost. For a battery, separately use the battery savings calculator.
Results are educational estimates, not a quote or guaranteed saving. Tariffs, rebates and installer availability may change.
