Why do solar panels typically face south? It all comes down to geometry. In the Northern Hemisphere, the sun travels across the southern part of the sky from morning to evening, so south-facing panels capture the most direct sunlight throughout the day. However, this approach is evolving. In the Southern Hemisphere, solar panels are oriented north. On a utility scale, we're seeing more east-west array layouts – not to maximize total energy yield, but to better align generation with the times when the grid needs power most. And increasingly, solar panels don't face a fixed direction at all. Tracker systems follow the sun across the day – east in the morning, near-vertical at noon, west in the evening. They lift yield – and on agri-PV sites, they raise the panels high enough for farming to continue underneath. Two uses. One surface. Where engineering once focused primarily on maximizing annual output, today's priorities are shifting to when electricity is actually required – and what else the land can do. Planning now means designing solar farms to meet the changing needs of the energy system.
