How Solar Installation Works

1

Site Assessment and Quote

An installer visits your property, assesses your roof, checks shading, and provides a detailed quote based on your energy usage.

2

System Design and Approval

Your system is designed to maximise output. Council approval may be needed for heritage properties, but most residential installs are exempt.

3

Installation

A residential solar installation typically takes one day. The team mounts panels, installs the inverter, and connects the wiring.

4

Grid Connection and Meter

Your installer lodges paperwork with your distributor. Once approved, your meter is upgraded to a bi-directional meter and you start exporting.
