Guildford's solar story since 2001

183 systems went in before 2011. The busiest year was 2020 (1,102), in the second wave of rooftop solar, and the quietest since 2011 was 2013. 2025 brought 951, 86% of that peak. 52% of its 11,126 systems went in from 2021, against 40% across Perth, so much of the postcode's solar is already sized for a battery. Systems grew from an average of 2.4 kW in 2011 to 8.6 kW in the last 12 months.
