Explore how solar generation varies with latitude and season. Compare typical daily patterns for different locations around the world.
About These Charts
Orange curve: Solar generation throughout the day (latitude-adjusted for each location)
Blue curve: Typical home energy consumption (25 kWh/day)
Green shaded area: Solar surplus - when your panels generate more than you use (exporting to grid)
Light shaded area: Grid consumption - when you're drawing power from the grid
Key Insight: Notice how London's winter curve is dramatically narrower (short winter days) while Sydney maintains more consistent generation year-round due to its lower latitude.

Key Observations
Sydney (Subtropical): Moderate seasonal variation (3.3 to 5.1 kWh/kW/day). Solar generation remains strong year-round with longer, more consistent daylight hours.
London (High Latitude): Extreme seasonal variation (1.2 to 4.5 kWh/kW/day). Summer days are exceptionally long with excellent generation, but winter days are very short with limited output.
Morning surplus: Both locations show significant excess solar generation during midday hours when typical home consumption is relatively low.
Evening deficit: Both locations rely heavily on grid power during evening consumption peaks (5pm-10pm) when families are home cooking, using appliances, and entertainment systems.
Battery storage value: The gap between generation and consumption patterns highlights the value of battery storage for shifting midday solar surplus to evening usage periods.
