Compare several written quotes from Wollongong installers, checking the system design, panel and inverter brands, total price, workmanship warranty and expected generation. Look for an installer with current Clean Energy Council accreditation and verify licences, reviews and references rather than relying on the cheapest offer. Ask how the system will suit your roof, coastal conditions, electricity use and any future battery plans. Eligibility for government support depends on the system, installer and your circumstances, so confirm current details through the official energy.gov.au website and check contract terms before signing.
