Adelaide has strong solar resources, but the best system depends on your roof orientation, shading, household electricity use and whether you want a battery. Ask a Clean Energy Council-accredited installer to compare panel quality, inverter capacity, likely generation and installation costs for your property. Small-scale Technology Certificates may reduce the upfront price, although the value and eligibility depend on the system, installer and current government rules. Compare quotes carefully, check the warranty terms and confirm any grid-connection requirements with your electricity distributor before signing.
