How Solar Installation Works
Site Assessment and Quote
An installer visits your property, assesses your roof, checks shading, and provides a detailed quote based on your energy usage.
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.
Installation
A residential solar installation typically takes one day. The team mounts panels, installs the inverter, and connects the wiring.
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.
