With roughly 2223 residents per square kilometre, Mount Waverley has the block sizes where a 6.6 to 10 kW system fits cleanly and the inverter has somewhere sensible to live. Mount Waverley is 16 kilometres from town. Middle-ring roofs are typically large enough that the design question is orientation, not area.
In Monash, which includes Mount Waverley, the paperwork that actually matters is the distributor's, not the council's, unless the building is protected. We treat Mount Waverley, Ashwood and Burwood as one working area rather than three separate postcodes.
Mount Waverley covers about 15.9 square kilometres of Monash. The 2021 census put the population at 35340, and the postcode is 3149. Some local background that shows up on the roof: Post Offices at Mount Waverley North (opened 1959 closed 1983), Mount Waverley South (opened 1968 closed 1973), and Mount Waverley West (opened 1964 closed 1977) chart the wider residential development of the suburb. The era a suburb was built tells us what roofing material and pitch to expect.
Our working patch either side of Mount Waverley takes in Ashwood, Burwood, Burwood East and Chadstone, which is why availability here is usually good. We are based in Boronia, about 13.7 kilometres west of Mount Waverley. Close enough that the person who quotes the job is the person who comes back to do it.
Mount Waverley has Mount Waverley railway station, which is a useful marker: closer to it usually means older wiring.
