Solar tiles replace part of the roof covering; above-roof panels sit on a mounting system over it. Conventional in-roof panels are a third option: they also replace a section of the covering, but use larger-format modules. The right comparison depends on the actual products, your roof layout and whether roofing work is already planned.
For a UK new build or re-roof, compare integrated options on the same roofing and electrical scope. For a sound existing roof, include an above-roof option before deciding that removing the covering is worthwhile. SolarTyle's solar roof tile cost guide sets out the published like-for-like pricing example and its limits.
Three solar roof options, not just two
| Option | Roof integration | Project fit |
|---|---|---|
| Solar roof tiles | Smaller-format electricity-generating tiles form part of the roof covering. | Consider on new builds or roofing projects where tile appearance and available roof shapes matter. |
| Conventional in-roof panels | Larger-format modules replace a section of covering, with a compatible weatherproofing system. | Consider alongside solar tiles when integrated solar is wanted; compare layout, finish and complete roof scope. |
| Above-roof panels | Modules sit on mounts above the retained roof covering. | Consider for suitable existing roofs; check their condition, access, fixing design and visual impact. |
SolarTyle is an integrated solar tile product, not a raised panel system. Explore the SolarTyle tile and the Full Roof Solution for the product and roof-system context.
Which produces more electricity?
Do not decide from the labels alone. Ask for the actual product datasheets and a layout-specific generation estimate. Module efficiency describes conversion under specified test conditions; installed capacity in kWp and predicted annual electricity in kWh answer different questions.
- Product: compare the specified module efficiency, rated power and dimensions, rather than assuming every panel outperforms every tile.
- Layout: compare how much capacity each design can fit on the usable roof, allowing for roof features and installation requirements.
- Generation: request predicted annual kWh using consistent location, orientation and shading assumptions.
See the SolarTyle product datasheet and why two 4 kWp systems can produce different electricity. Neither a module rating nor a generic comparison guarantees a household's annual output.
Compare the same work, not just the headline price
Ask each quotation to identify what is included. Keep the solar system comparison separate from the cost of replacing the rest of the roof, then compare the total project cost. A solar-only price and a complete re-roof quotation are not interchangeable.
- Specify the solar product, capacity, roof area and retained or replacement covering.
- Confirm VAT treatment, electrical equipment and connection, labour and access or scaffolding.
- Identify stripping, repairs, battens and non-solar tiles; show any battery as a separate option.
Use the dated SolarTyle versus conventional in-roof cost example as a starting point, not a fixed quotation for every property. This comparison does not assume guaranteed savings, payback or an increase in resale value.
Start with the roof you actually have
New build: include the solar layout in the roof design and compare integrated options before specifying the covering. Re-roof: agree the condition and replacement scope first; our roof replacement guide explains the combined-project approach. Existing sound roof: weigh the value of an integrated finish against the work needed to change the covering.
A roof needing repairs should not be treated as a sound-roof retrofit without assessment. Use our pre-quote roof checklist to gather your postcode, roof plans or photographs, proposed roofing work and electricity usage. These details make the comparison more useful than choosing from a generic price or efficiency headline.
Request a comparison for your roof
Send your project details and ask for the proposed SolarTyle layout and a written quotation scope. Compare that with the alternative design on the same assumptions before choosing.
