There is no standard Clean Energy Council installer fee: each installer sets its own price based on the system size, roof access, switchboard work, travel and whether a battery is included. Ask for a detailed, itemised quote showing equipment, installation, approvals, monitoring and any ongoing costs. Using a CEC-accredited installer may be required for some government incentives, but accreditation alone does not guarantee the cheapest quote or a particular quality outcome. Compare several written quotes and verify the installer’s current accreditation through the Clean Energy Council before signing.
