The quality of installation and after-sales support varies significantly between solar companies, and a cheap quote isn't always the best value once warranty and service are factored in. This page is general guidance, not a recommendation of any specific company.
Accreditation matters
Look for installers and designers accredited by the Clean Energy Council — this is generally required to access government rebates, and accredited installers are expected to follow specific safety and quality standards.
Comparing quotes
Getting at least two or three written, itemised quotes lets you compare panel and inverter brands, system size, warranty terms, and total price on a like-for-like basis, rather than comparing a headline number alone.
Red flags to watch for
High-pressure sales tactics, door-knocking offers with a deadline 'today only', and quotes that seem far cheaper than others for a similar system size are all worth treating with caution — take time to compare rather than deciding on the spot.
Warranties
Panels, inverters and the installation workmanship typically carry separate warranty periods from different parties, so check each one specifically rather than assuming a single blanket warranty covers everything.
Key takeaways
A little research before signing — checking accreditation, comparing written quotes, and reading warranty terms carefully — tends to matter more for long-term satisfaction than chasing the single lowest price.
