On the Gold Coast, compare the system’s expected output using your household’s electricity use, roof orientation, shading and local weather conditions. Ask whether the installer is accredited by Solar Accreditation Australia and whether the quote clearly covers equipment, installation, warranties, monitoring and connection to the Energex network. Coastal salt exposure, strong winds and the condition of your roof are also worth discussing during the site assessment. Small-scale Technology Certificates (STCs) may reduce the upfront price for eligible systems, but the value and eligibility depend on current rules and your circumstances, so check energy.gov.au and review the written quote carefully.
