What this covers

Adding panels to an existing residential system where the roof and switchboard allow.

Before the solar installer arrives

  • Keep clear of the roof edge and any temporary ladders or scaffolding.
  • Note your latest electricity bill and whether you already have solar or a battery.
  • If the roof is wet or storm-damaged, stay off it until it is inspected.
