As a renter, you’ll generally need your landlord’s written permission before installing rooftop solar, batteries or equipment connected to the home’s wiring, and a licensed electrician must do any electrical work. Ask whether your landlord would consider a system, including how installation costs, ownership, maintenance and moving out would be handled. If rooftop solar is not suitable, you could compare community solar schemes, a retailer’s accredited GreenPower options, or small portable solar products that are not connected to the property’s wiring. Check your lease, body corporate rules and energy retailer, and use energy.gov.au for Australian guidance.
