Homeowners can usually install rooftop panels or a battery, subject to local rules, network requirements and any approval from a body corporate. Renters generally need the landlord’s written permission, and may prefer portable panels, a green-power electricity plan or a community solar scheme where available. Rental agreements, installation ownership and who receives any export credits should be agreed in writing before work begins. Rebates and incentives, including small-scale technology certificates, depend on the system and individual circumstances, so check current information at energy.gov.au and ask an accredited installer or energy provider.
