Solar in Holland Park — What You Need to Know
Holland Park is a classic inner-south Brisbane suburb of post-war brick homes built on the slopes below Mount Gravatt's ridge, combining affordable early-ownership demographics with increasingly affluent professional families attracted by the inner-city position. The Queensland Housing Commission built extensively in Holland Park in the 1950s–60s, and the state's housing portfolio solar retrofit program has made these Commission homes among the suburb's most solar-equipped. For private homeowners, the suburb's 1960s–80s homes on 600–700m² lots are straightforward solar installations with good north-facing orientations on the slopes. Brisbane City Council's southern programs serve Holland Park within the Mount Gravatt catchment, and the suburb's competitive installer market from both the inner south and south-east Brisbane provides reliable pricing.
