Homeowners can usually explore rooftop solar, subject to the property’s roof, electricity use, local rules and a suitable installer’s assessment. Renters should get written approval from the landlord before installing anything, and may instead consider a portable solar system, a community energy scheme or a competitive renewable electricity plan. People in apartments or strata properties may need body corporate approval and could investigate shared or embedded solar arrangements. Costs, savings and eligibility vary, so compare offers carefully and check the setup with your landlord, strata manager, energy retailer or a licensed solar professional.
