Solar in Mount Gravatt — What You Need to Know

Mount Gravatt sits on the highest ground in Brisbane's south, with GRIFFITH University's campus occupying the summit and residential streets cascading down to the north, east and west. This elevation advantage is real and measurable for solar: homes on the north-facing slopes of Mount Gravatt East and Mansfield have clear solar horizons from around 7:30am. The suburb's housing stock is predominantly 1970s–90s brick homes on 600–800m² blocks, with a high owner-occupier rate and strong family demographics. Logan Road and the Mount Gravatt-Capalaba Road corridor create a competitive local installer market, with multiple CEC-accredited businesses competing for the suburb's consistent installation demand.
