The southern stretches of the Monaro Highway make for a wholesome pastoral drive, with fields full of cows and golden grass swaying in soft breezes. The road winds around hills and dams, then tips up and over a crest to reveal an unexpected sight: thousands of solar panels shining in the harsh Australian sun.

This is the Royalla Solar Farm, a paddock holding tens of thousands of solar photovoltaic modules that together are capable of powering 4500 Canberra homes. Despite being part of Australia's smallest territory, Royalla is just the tip of the iceberg when it comes to the ACT's solar accomplishments.
