Do solar panels work on a north-facing roof?

Yes, but north is the weakest orientation, and a purely north-facing roof often is not worth doing on its own. The honest answer depends on the pitch of the roof, the shading around it and whether you have any better-facing space to use instead, which is exactly what we check before recommending anything.

In the UK a south-facing roof captures the most sun and delivers the greatest savings. East and west-facing roofs are the quiet performers: each loses only a modest amount compared with south, and together an east-west split spreads generation across the morning and the evening rather than piling it all into the middle of the day, which suits a home that uses most of its power before and after work. A north-facing slope sits at the bottom because it gets no direct sun for most of the day, so the same panels simply make less.

That does not always rule it out. The shallower the pitch, the less the orientation matters, a nearly flat north-facing section behaves far more like a flat roof than a wall, so the penalty shrinks. And if north is the only space you have but your electricity use is high, some generation can still beat none. The point is that it is a judgement call on your particular roof, not a blanket yes or no.

In practice, shading usually matters more than a few degrees of facing. A chimney, a tall tree, a dormer or a neighbour's roofline can cost you more than a north aspect does, and the loss is rarely obvious standing in the garden. Panel-level electronics such as optimisers or microinverters help, because they stop one shaded panel from dragging down the rest, but they manage shade rather than remove it. We map how the shadows move across your roof through the day so the design works around them.

Leicester's housing is a real mix, Victorian and Edwardian terraces, 1930s semis, post-war estates and newer builds, and the roof you have shapes what is sensible. Older terraces often give you one good slope and one poor one; many semis offer a tidy east-west pair; newer homes face whichever way the estate happened to be laid out. We work with what your roof actually offers rather than forcing panels onto a slope that will not earn its keep.

If your only real option is north-facing and the numbers do not stack up, we will tell you, the same way we would talk you out of a system that is bigger than you need. If you have got better-facing space, we will use it. Either way you get a straight answer for your specific roof instead of a sales pitch, worked out during a free assessment.
