Map and Orientation: Getting the Best from Your Plug-in Solar System

To maximise electricity generation in the UK, the orientation and tilt of your solar panels play a crucial role.

Optimal Performance

For the highest possible annual yield across most of the UK, panels should face true south and be tilted at approximately 35 degrees. This angle strikes the best balance for capturing sunlight throughout the year.

Vertical Mounting on Balconies

If you’re installing panels vertically (flat against a balcony railing or wall), expect to generate roughly 30% less energy compared to the optimal 35-degree south-facing angle.

However, even with this reduction, a vertical balcony-mounted system can still deliver significant savings and remains a very worthwhile investment — especially in space-constrained urban settings where no other mounting option is available.
