Solar in Kew — What You Need to Know
Kew is one of Melbourne's most distinguished inner-eastern suburbs, characterised by Federation and Edwardian mansions on the elevated ground above the Yarra River's southern bank. The suburb's housing scale is the defining solar factor: roof areas routinely exceed 200–300m², supporting 13–20kW systems that are impractical on smaller metropolitan lots. Boroondara City Council's heritage overlay covers extensive portions of Kew, but the council's all-black panel guideline is well-established and the suburb has a long track record of heritage-approved solar installations. Kew's demographics are Melbourne's highest-income residential market — executives, professionals, and established families with electricity bills averaging $4,000+ annually from large homes with ducted systems, heated pools, and home offices. Battery storage is taken up at 40% of new installs — Melbourne's highest rate — reflecting a demographic with financial planning sophistication and interest in whole-energy-system optimisation.
