The Clean Energy Council installer guide can help you compare installers, check accreditation and ask the right questions before signing a contract. Look for an installer with current CEC accreditation relevant to your system, and confirm who will handle design, approvals, warranties and after-sales support. Get detailed written quotes that list the panels, inverter, battery if applicable, expected installation timeframe and total price. You can also verify accreditation through the Clean Energy Council and seek advice from a licensed electrician about your specific property and proposed system.
