Frequently Asked Questions
What is a solar score for Perth?
Your solar score is a personalised rating out of 100 that tells you how well-suited your Perth home is for solar panels. It factors in 5.4 daily peak sun hours, your roof orientation, electricity bill, available rebates, and battery benefit to give you a clear picture of potential savings.
How accurate is the Perth solar score?
Our algorithm uses real Bureau of Meteorology sun data for Perth, current WA electricity rates, and up-to-date rebate information. While no online tool replaces a professional site inspection, our scores consistently align with installer assessments for the majority of homes.
How long does it take to get my solar score?
About 60 seconds. You answer 6 quick questions — postcode, roof direction, electricity bill, household size, battery interest, and home ownership — and we calculate your personalised score immediately. No signup, no email required.
Can I get installer quotes through SolarScorecard in Perth?
Yes. After receiving your solar score, you can optionally request quotes from up to 3 CEC-accredited solar installers in the Perth area. This is completely optional — you can use the tool without providing any contact details.
