In the UK, south-facing roofs receive the most direct sunlight throughout the day, which is why they are considered ideal for solar panels. East- and west-facing roofs also perform well, generating electricity during morning or afternoon hours. North-facing roofs, however, receive less direct sunlight, particularly during winter months. This reduced exposure naturally affects how much electricity solar panels can produce over the course of a year. That said, roof orientation is only one part of the equation. Factors such as roof pitch, shading, panel efficiency, and household energy usage patterns all play an important role in determining whether a north-facing solar system makes sense.
