What size solar system do I need in Gray?
For an average Gray household using 20-25kWh per day: a 6.6kW system covers most needs. Larger households (30kWh+) should consider 10kW or 13.3kW systems. If you have or plan to add an EV charger or heat pump hot water, size up. Your sunny climate means a standard-sized system will perform well.
What direction should solar panels face in Gray?
North-facing is ideal for maximum annual output in Gray. 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.
