Sydney sees strong solar returns thanks to high electricity tariffs and good year-round sun. We install right across Greater Sydney and the surrounding metro area.

Greater Sydney rooftops vary enormously, so we assess yours in person: pitch, orientation, available space and anything casting shade across the day. We match the design to how your household actually uses electricity, then a CEC-accredited crew handles the install with Tier 1 panels and gear specified for the job.

GET A SYDNEY BUSINESS QUOTE Why Sydney businesses go solar From federation semis in the inner suburbs to two-storey homes out west, Sydney roofs differ street by street, and layout has to work with what is actually up there. Western Sydney summers get considerably hotter than the coast, so air conditioning drives daytime demand there, while eastern suburbs homes often deal with shading from mature trees and neighbouring apartments. Ausgrid and Endeavour Energy each set their own connection and export rules, so the design has to suit whichever network your street sits on.

Commercial systems up to 100kW can be eligible for small-scale technology certificates (STCs), applied as an upfront discount; larger systems use large-scale generation certificates (LGCs). Eligibility criteria apply. EFS Solar is not affiliated with any government body. See our solar & battery rebates guide for the current detail.
