Installation Requirements
Solar panels can be retrofitted onto most existing roofs with minimal alterations. Installation is relatively quick, often completed within a few days.
Solar tiles, however, typically require a full roof replacement, making them more suitable for new builds or major renovations. Installation is more complex and time-consuming.
Planning permission is generally not required for solar panels, except in conservation areas or listed buildings. Solar tiles are often preferred in these areas due to their discreet appearance.
What Type of Property Is Best Suited for Solar Tiles or Solar Panels?
Solar Tiles:
- New builds.
- Heritage or listed buildings.
- High-end homes where aesthetics are a priority.
Solar Panels:
- Most domestic homes and flats.
- Retrofits on existing roofs.
- Commercial buildings with large roof spaces.
Roof Compatibility
Solar Panels:
- Can be mounted on most UK roof types (tile, slate, flat roofs with angled mounts).
- Require minimal roof alteration.
- Suitable for older properties.
Solar Tiles:
- Usually installed during roof replacement or new builds.
- Not suitable for all roof pitches or structural layouts.
- It may not be viable for fragile or irregular roofs.
Other compatibility factors:
- Roof orientation and angle affect both options.
- Structural integrity needs assessment, especially for tile systems.
Solar Tiles vs Solar Panels: Compatibility with Other Home Systems
Both solar tiles and panels can be integrated with:
- Solar batteries for energy storage.
- Grid-tied systems to sell excess energy.
- Combi boilers, though additional equipment may be needed.
Which Is More Efficient: Solar Tiles or Solar Panels?
Solar panels typically have efficiency rates between 15% and 22%, while solar tiles range from 10% to 17%. Panels benefit from better airflow and can be angled optimally, enhancing performance. Tiles, being flush with the roof, may have reduced airflow and are limited to the roof’s pitch, potentially decreasing efficiency.
In the UK’s less sunny climate, maximising efficiency is key, especially during colder months, as solar panels do work during winter, but may not be as effective. Homes with limited roof space may find that higher-efficiency panels offer better value per square metre.
Which Lasts Longer: Solar Tiles or Solar Panels?
Both solar panels and tiles have lifespans of around 25 to 30 years. Panels are more exposed but are designed to withstand UK weather conditions. Tiles, integrated into the roof, offer better protection against wind damage.
Maintenance for panels is generally easier, as individual units can be replaced. Tiles may require more work to service or replace faulty sections. Warranty terms vary; panels often have separate product and performance warranties, while tile warranties may be tied to the roof installation.
Solar Tiles vs Solar Panels: Aesthetics
When it comes to how your solar setup looks, aesthetics can be a major deciding factor, especially for homeowners aiming to preserve their property’s kerb appeal. Both solar panels and solar tiles offer clean energy, but they do so with very different visual impacts.
Solar tiles
Solar roof tiles are designed to blend in with traditional roofing materials. Whether you’re building a new home or re-roofing an older property, solar tiles provide a sleek, modern, and low-profile appearance.
From street level, it’s often difficult to tell the difference between solar tiles and conventional slate or tile roofing.
For properties in conservation areas or with strict planning restrictions, solar tiles in the UK are becoming increasingly popular as they offer a way to install solar technology without compromising heritage aesthetics.
Solar Panels
Traditional solar panels, while efficient and cost-effective, are bulkier and typically mounted on top of your existing roof. This raised and noticeable design can contrast sharply with older or character homes, which is why some homeowners feel they detract from the property’s appearance.
That said, modern options like all-black monocrystalline panels have significantly improved in design. These panels offer a more uniform, minimalist finish compared to the older blue-and-silver polycrystalline styles.
While not invisible, today’s solar panels are a step forward in balancing performance with appearance.
If you’re concerned about how panels will look on your roof, it’s also worth considering the layout and orientation. A well-planned installation can enhance symmetry and curb appeal.
Read our guide on horizontal vs vertical solar panel installation to understand the aesthetic differences.
If you’d rather avoid roof-mounted panels altogether, ground-mounted solar systems can be a great alternative, especially if you have available garden space.
These setups remove any visual impact on your roof and allow for optimised positioning to maximise sunlight exposure.
Solar Tiles vs Solar Panels: Energy Generation
Under typical UK conditions:
- Solar Panels: Standard panels produce between 350 and 450W each.
- Solar Tiles: Generally have lower output per m², requiring more tiles to generate the same energy as panels.
For example, a 4 kW panel system may need approximately 10–12 panels, while a tile system would require a larger roof area and more tiles to achieve the same output.
Which Is Better for Your Home or Business in the UK: Solar Tiles or Solar Panels?
Choose Solar Panels if:
- You’re budget-conscious
- You have an existing roof suitable for retrofitting
- You prioritise efficiency over aesthetics
Choose Solar Tiles if:
- You’re undertaking a new build or major renovation
- Your property is listed or in a conservation area
- Aesthetics are a top priority
Frequently Asked Questions (FAQs)
