Rooftop solar in bushfire-prone areas adds questions about embers, debris in array gaps, and access for defenders. Panels themselves are not magical fire starters, but poor housekeeping around roofs raises risk like any neglected structure.
Ember traps at the roof interface
Leaves under arrays, blocked gutters, and timber debris near eaves are classic ember catchers. Design and maintenance should keep those zones inspectable.
- Schedule pre-season roof and gutter cleans including under-array edges
- Ask designers about sarking, flashing, and BAL-relevant detailing
- Keep inverter and battery clearances free of stored fuels
- Know isolation procedures if authorities advise shutdown
Fire season maintenance is part of system ownership in ember country.
During warnings
Follow official advice. Do not climb roofs under catastrophic conditions to “save” panels. Isolation decisions belong to trained residents following their bushfire plan.
After fire or ember attack
Assume electrical damage until inspected. Document conditions for insurers; do not re-energise damaged arrays.
Vegetation management
Trees that shade panels may also be fuel. Balance yield pruning with fire-agency guidance for your block.
