For renters, the main options are asking the landlord to install a system, joining a community solar programme, choosing a certified portable solar setup, or buying a renewable electricity plan from a retailer. Landlord-installed panels may provide the greatest bill savings, but require approval and agreement about ownership, maintenance and what happens when you move. Portable systems are more flexible, although their output is usually limited and they must be installed safely. Community solar and green-power plans avoid property changes, but costs and availability vary by location. Compare upfront costs, expected savings, contract terms and portability, and check safety requirements with a licensed electrician.
