When it comes to getting the most out of your solar panels in North London, the direction your roof faces can make a big difference to your system’s performance and return on investment.
Here’s how roof direction, tilt, and shading impact your energy generation.
🧭 South-Facing Roofs – The Ideal Setup
For UK homes, south-facing roofs receive the most sunlight throughout the year. In North London, a south-facing solar system can achieve up to 100% of optimal generation.
✅ Best for all-day sunlight
✅ Highest annual output
✅ Shortest payback period
If your home has a clear, unshaded south-facing roof, you’ll enjoy the best results from your solar investment.
🌅 East- or West-Facing Roofs – Still Excellent
If your roof faces east or west, don’t worry — you can still reach 80–90% of south-facing performance.
- East-facing roofs: More morning energy
- West-facing roofs: More afternoon and evening energy
Many North London homes benefit from split arrays (half east, half west) for steady generation all day long.
🌤️ North-Facing Roofs – Limited, But Possible
North-facing roofs produce less power, but with modern high-efficiency panels, optimisers, and tilt frames, they can still generate a significant amount of electricity.
At Keenan Solar, our in-house team designs every system to get the most out of your roof — even if it’s not perfectly positioned.
📐 Ideal Roof Angle
For maximum efficiency in North London, solar panels should sit at around a 30–35° tilt angle. This helps capture the most sunlight across all seasons and keeps panels self-cleaning when it rains.
