What stands out in Bicton

• 26 new solar systems per 1,000 homes in the last 12 months, 37% below the Perth rate: fewer roofs are still getting their first system.
• 42 home batteries for every 1,000 homes since Jul 2025, 35% below the Perth rate.
• 61% of homes are separate houses (78% across Perth), so more homes share a roof or need strata approval.
• Smaller households: 2.3 people on average (2.6 across Perth), so evening use is usually lower.
