Rooftop solar in Australia hit a stunning new high in 2017, with homeowners, schools, and small businesses installing roughly 9,500 panels every single day. The country added 1,057 megawatts of small-scale solar capacity in a single year — enough to rival a medium-sized coal plant, but spread across millions of ordinary rooftops. Average system sizes doubled compared to five years earlier, as falling prices turned solar from a niche eco-choice into a practical way for households to take charge of their power bills. It’s a hopeful reminder that the energy transition isn’t only happening in distant policy rooms or massive infrastructure projects — sometimes it’s being built one sunny rooftop at a time.
