High Wycombe's solar story since 2001

342 systems went in before 2011. Then came 2011, the postcode's busiest year (468), during the first rush of rooftop solar; the quietest since was 2015. 2025 brought 175, 37% of that peak. 33% of its 4,283 systems went in between 2011 and 2015, against 29% across Perth. Many were 2.2 kW systems now past ten years old, so adding a battery to existing solar, or replacing an early system, comes up often (see a battery for existing solar). Systems grew from an average of 2.2 kW in 2011 to 9.8 kW in the last 12 months.
