What direction should solar panels face in Humpty Doo?
North-facing is ideal for maximum annual output in Humpty Doo. West-facing produces more in the afternoon (good if you use more power in the evening). East-facing produces more in the morning. Even a flat roof works well. Avoid south-facing if possible, as output can be 20-30% less than north-facing in Northern Territory.
