What Are In-Roof Solar Panels?
Unlike traditional on-roof solar panels that sit on top of your existing tiles, in-roof solar panels—also known as roof-integrated PV systems—are installed flush with the surface of your roof. This integration replaces a portion of your roof tiles or slates, allowing the panels to become part of the roofing structure itself.
In-roof panels are compatible with various roof types, and they offer a more seamless appearance, often appealing to homeowners in modern builds or conservation areas. Options like solar roof tiles in the UK and integrated systems are becoming increasingly popular due to both aesthetic and functional advantages.
Benefits Of In-Roof Solar Panels
1. Aesthetically Pleasing Design
One of the most noticeable advantages of in-roof vs on-roof solar panels is their clean, streamlined appearance. The panels sit flush with the roofline, giving a minimalist, low-profile look that blends into your home’s architecture.
For properties in visually sensitive areas—such as heritage zones or new builds with planning restrictions—this aesthetic can be a game changer.
2. Enhanced Energy Efficiency
Integrated systems can improve insulation and help maintain a consistent roof temperature, which may slightly increase your home’s overall energy efficiency. Because the panels are built into the roof, there is less air circulation underneath, reducing heat loss.

3. Better Weather Resistance
Roof-integrated PV systems offer enhanced protection against the elements. With fewer gaps between tiles and panels, there’s reduced risk of wind uplift and water ingress. This makes them a sturdy, weather-resilient choice—particularly valuable in the UK’s unpredictable climate.
4. Space Efficiency
In-roof systems use the existing roof space without requiring additional mounting equipment. This is especially useful in homes with limited roof real estate or unusual shapes, ensuring no space goes to waste.
Additionally, the removal of some traditional tiles may slightly reduce the weight burden compared to mounting systems on top of an existing roof.
5. Long-Term Property Value
Installing in-roof solar panels can be a strong selling point if you decide to move. Buyers are increasingly looking for renewable energy for homes, and a visually appealing, energy-efficient solution can increase market value and reduce time on the market.
How To Install A Solar Panel In The Roof?
Installing an in-roof system is typically done during a re-roofing project or as part of a new build. Here’s a simplified overview of the installation process:
- Assessment & planning: Your installer evaluates the roof structure and orientation for optimal sun exposure.
- Roof preparation: Roof tiles or slates are removed where panels will be fitted.
- Panel integration: Special mounting kits are used to fit the in-roof solar panel kit securely into the roof structure.
- Electrical setup: Panels are connected to an inverter, and your system is linked to the home’s electrical circuit or battery storage.
- Testing & commissioning: The system is tested to ensure it meets all safety and performance standards.
Hiring an experienced installer, such as Alpha Tech Group, ensures the system complies with UK regulations and performs reliably for years to come.
In-Roof Solar Panels Maintenance
Another advantage of in-roof solar panels is their minimal maintenance requirements. Here’s what you need to know:
- Cleaning: Rain usually keeps panels free of dust, but occasional cleaning improves performance.
- Inspections: An annual check by a professional can identify issues like loose connections or shading problems.
- Repairs: Since the system is built into the roof, replacing damaged panels may require specialised care, but high-quality installations reduce the likelihood of such issues.
With proper installation and periodic checks, your system should perform efficiently for 25 years or more.
In-Roof Vs On-Roof Solar Panels
Here’s a quick comparison to help you decide which system might suit your needs:
| Feature | In-Roof Solar Panels | On-Roof Solar Panels |
| Aesthetics | Sleek, flush with roof | More prominent |
| Installation | Integrated during roofing | Mounted on top of existing roof |
| Weatherproofing | Excellent | Very good |
| Cost | Slightly higher | More cost-effective |
| Ideal For | New builds or re-roofs | Retrofit projects |
Both systems offer renewable energy for homes, but in-roof systems bring a premium look and integrated performance.
