Renters can compare portable panels with a battery, landlord-approved rooftop solar, community solar schemes and a retailer’s GreenPower option. Portable panels are flexible but generally suit charging a battery or small appliances; connecting equipment to household wiring requires compliant products, a licensed electrician and the landlord’s approval. Landlord-installed solar may offer greater bill savings, but you should agree in writing who pays, owns and maintains the system, and what happens if you move. Availability and costs vary, so check your tenancy rules, energy retailer and energy.gov.au before deciding.
