When people across Surrey, Hampshire, and Berkshire first consider solar, one question almost always comes up: “Is my roof suitable?”
The good news is that most homes can support a solar system. While not every roof is ideal, modern technology makes solar more flexible than ever. Here’s what you need to know when checking if your roof is ready for panels.
1. Roof Orientation: Which Way Does It Face?
South-facing roofs: These get the most direct sunlight in the UK and deliver maximum efficiency.
East- and west-facing roofs: Still very effective, often generating around 80–90% of the energy of a south-facing system.
North-facing roofs: Less ideal, but sometimes possible with additional design considerations.
2. Roof Angle: Finding the Sweet Spot
Solar panels work best when angled between 30° and 40°. That said, don’t worry if your roof pitch is different:
Flatter roofs can use tilted mounting frames.
Steeper roofs may still perform well, though shading plays a bigger role.
3. Shading: The Silent Efficiency Killer
Nearby trees, chimneys, or tall buildings can reduce solar output. However, new technologies such as microinverters and optimisers help minimise shading impact, meaning partial shading doesn’t necessarily rule out solar anymore.
4. Roof Size: Do You Have Enough Space?
A typical 3–4 bedroom home needs 10–16 panels, which requires 20–30m² of roof space.
Smaller roofs can still make a meaningful difference — even 6 panels can noticeably reduce bills.
5. Roof Condition and Strength
Solar panels are lightweight (about 18–22kg each), but the roof should be in good condition before installation. A professional survey will check whether repairs are needed first.
6. Local Considerations in Surrey, Hampshire & Berkshire
Surrey: Many homes are in conservation areas. Solar is often permitted development, but visible installations on listed buildings may need planning approval.
Hampshire: Larger rural properties often benefit from expansive, south-facing roofs perfect for higher-capacity systems.
Berkshire: Many towns feature modern builds with uniform roof angles, making installation straightforward.
Always check with your installer about local planning rules — most will handle applications on your behalf.
7. Common Misconceptions About Roof Suitability
“My roof isn’t south-facing, so solar won’t work.”
→ East- and west-facing roofs can still be very efficient.“My roof is too small.”
→ Even a smaller system lowers bills and gives energy independence.“Solar panels are too heavy.”
→ Most roofs can easily support panels. Only very old or damaged roofs need reinforcement.
8. What If My Roof Isn’t Suitable?
If your roof really isn’t right for panels, alternatives exist:
Ground-mounted systems: Ideal for properties with land.
Solar carports: Panels integrated into covered parking areas.
Community solar schemes: Shared solar projects that let you benefit even if your home can’t host panels.
Conclusion: Checking Your Roof Suitability
In most cases, your roof will be suitable for solar — even if it’s not perfectly south-facing or textbook angled. The best way to find out is with a professional, no-obligation survey.
