Start by asking your landlord or property manager whether they would consider a professionally installed system, and agree in writing who pays, owns and maintains it. If rooftop panels are not practical, look into community solar schemes, a renewable electricity plan, or a small approved solar setup for a caravan or balcony where permitted. Avoid plugging DIY panels into household power points, as Australian electrical rules and safety requirements may apply. Compare offers carefully and check energy.gov.au or a licensed electrician for advice relevant to your property.
