Best Solar Installers in Sydney
Sydney is Australia's largest solar market by installation volume, and competition among installers is fierce. That means good deals are available, but so are fly-by-night operators looking to undercut on price at the expense of quality. We evaluated installers across Greater Sydney on their accreditation, track record, customer feedback, and after-sales support.

Customer reviews

Track record
Years in business under the same name, installation volume, and complaint history.
Warranty terms
Workmanship warranty length, how warranty claims are handled, and company financial stability.
Local expertise
Familiarity with Sydney's electricity networks, council rules, and common roof types.
Pricing transparency
Clear quoting with no hidden costs. Willingness to itemise costs and explain line items.
Solar in Sydney: What You Need to Know
Two electricity networks cover Sydney: Ausgrid (east) and Endeavour Energy (west). Each has different export limits and connection processes.
Sydney's housing stock varies enormously, from Federation terraces in the Inner West to modern builds in the Hills District. Panel placement and wiring complexity differ significantly.
Coastal suburbs (Northern Beaches, Eastern Suburbs, Sutherland) see salt spray which can affect panel frame corrosion. Ask about frame anodisation quality.
Strata buildings are increasingly adopting solar through embedded networks, but you need an installer experienced with body corporate processes.
State rebates and incentives
NSW does not currently offer a state-level solar rebate, but federal STCs still apply. The Energy Savings Scheme provides additional incentives through participating retailers.
