Do Solar Panels Work on a North-Facing Roof?
Yes, solar panels can still work on a north-facing roof in the UK, but output is usually lower than on a south-facing roof, so the roof has to be assessed carefully. Energy Saving Trust says the average domestic solar system is around 3.5kWp, and whether a north-facing roof is worth using depends on orientation, pitch, shading, and how much generation you would still capture.
The right answer is not simply yes or no. It is whether the roof still generates enough power to justify the installed cost.

When Can a North-Facing Roof Still Be Worth It?
A north-facing roof can still be worth it when the pitch is not too steep, shading is limited, and the household can use the generation efficiently. MCS reported more than 120,000 certified solar installations in the first half of 2025, which reflects how mainstream solar has become even on roofs that are not textbook-perfect.
The best cases are usually:
- Low-pitch roofs.
- Minimal shading from trees or neighbouring buildings.
- Large enough roof area.
- Homes with good daytime electricity use.
| Roof condition | North-facing solar outlook |
|---|---|
| Low pitch, low shade | Often still viable |
| Steep pitch, high shade | Usually weak |
| Mixed east-west or split roof | Sometimes better than north-only |
The survey should compare likely generation, not just the compass direction.
When Is a North-Facing Roof a Poor Candidate?
It is usually a poor candidate when the roof is both north-facing and heavily shaded or steeply pitched, because output drops too far to justify the spend. Energy Saving Trust’s average-system benchmark is useful here because it reminds homeowners that the size and quality of the generation matter more than simply fitting panels for the sake of it.
That means a poor roof may be better handled by:
- Using another roof face if available.
- Reducing system size to what actually performs well.
- Delaying solar until a wider roof project is planned.
Good solar design is about honest yield, not maximum panel count.
What Does This Mean in London, Surrey, and TW Homes?
In London, Surrey, and TW homes, north-facing roofs are common enough that they need a measured answer rather than a blanket rejection. MCS’s strong solar installation growth in 2025 shows the market is mature enough that roof-specific design is now the normal approach, not a niche exercise.
Terraces and semis with multiple roof faces can still be good candidates even when one side faces north. Detached homes with more roof choice usually have more flexibility.
How Electromatic Can Help
If you want to know whether your north-facing roof is still worth using for solar, Electromatic can assess orientation, pitch, shading, and likely output before you commit. That gives you a realistic answer instead of a generic myth that north-facing roofs always fail.
Electromatic works under MCS certification via our accredited umbrella partner and can also assess whether the property is better suited to a wider heat pump + solar combo. Book your free home survey →

Frequently Asked Questions
Do solar panels generate anything on a north-facing roof?
Yes, they can still generate electricity. The issue is whether the output is strong enough to make the economics sensible.
Are north-facing solar panels always a bad idea?
No. Some are viable, especially on low-pitch roofs with little shading.
Is east-west better than north-facing for solar in the UK?
Often yes, because east-west roof faces usually offer a stronger generation profile than a north-facing roof.
Can battery storage make north-facing solar more worthwhile?
A battery can improve self-consumption, but it does not fix weak generation. The roof still has to produce enough electricity in the first place.
Do I need a survey for a north-facing roof?
Yes. A proper roof assessment is the only reliable way to judge whether the roof is worth using.
