Homeowners can generally explore rooftop solar, batteries and eligible incentives, subject to their property, electricity connection and local requirements. Renters usually need the landlord’s written permission before making changes, and may instead consider portable systems, a green-power plan or a community solar scheme where available. A landlord may agree to install a system, but the costs, ownership and benefit of any exported electricity should be set out clearly in writing. Check the arrangement with your electricity retailer, landlord and a licensed solar professional before committing.
