Solar in Molonglo — What You Need to Know
Molonglo Valley is Canberra's newest urban district, a greenfield development on the Molonglo River corridor that is being built out progressively from 2013. Every home built in Molonglo has been subject to the ACT's Sustainable Homes standards requiring solar-ready conduit, and the district's first suburbs (Coombs, Wright, Whitlam) have recorded the ACT's highest and fastest solar adoption rates post-construction. The ACT Government's zero-interest solar loan scheme has been actively promoted to Molonglo residents, and the district's professional young family demographic — drawn by the attractive new suburban environment at competitive land prices — has taken up the offer at above-average rates. Molonglo's homes are modern energy-efficient builds that pair well with solar: good insulation reduces base consumption while solar handles the remaining load, with battery attachment rates of 46% among the highest in any new Australian suburb.
