Solar in Hawthorn — What You Need to Know
Hawthorn is one of Melbourne's leafiest inner suburbs, with mature elm, oak, and plane trees creating heavy canopy over many properties. Boroondara Council has some of Melbourne's strictest heritage controls, with many properties individually listed on the heritage overlay. Solar installations on heritage homes require a planning permit, and panels must not be visible from the street. The significant tree coverage means shade analysis is essential — microinverters or optimisers are the default recommendation for Hawthorn installations to handle the complex, shifting shade patterns.
