Solar Tiles in Ireland
Solar tiles — also called solar roof tiles or solar slates — replace conventional roofing materials with photovoltaic cells built directly into each tile. They generate electricity while weatherproofing your roof, with no visible panels or racking.
Quick Answer
Solar tiles cost 2.5–3x more than conventional solar panels (€16,000–€24,000 for a 4 kWp system vs €6,000–€9,000 for panels). They're eligible for the SEAI grant of up to €2,100 but availability in Ireland is very limited — most brands don't sell here yet. Solar tiles make the most sense for new builds, full re-roofs, or homes in conservation areas where traditional panels face planning objections.

What are solar tiles?
Solar tiles are building-integrated photovoltaics (BIPV) — roofing materials with solar cells embedded directly into them. Unlike traditional solar panels that mount on top of your existing roof with brackets and rails, solar tiles replace your roof covering entirely.
How they work
Each tile contains monocrystalline or thin-film PV cells sealed under tempered glass. Tiles interlock like conventional roofing and connect together electrically, feeding into a standard solar inverter.
Dual purpose
Solar tiles serve as both your primary weatherproofing layer and your power generation system — no separate racking, no penetrations through your existing roof membrane.
Appearance
From the street, solar tiles look like a conventional slate or flat tile roof. There are no protruding frames, no visible wiring, and the roofline stays clean.
Mixed installations
Most systems mix active (PV) tiles with inactive (non-generating) tiles of the same design, so only the south-facing sections generate power while the whole roof looks uniform.
Solar tile brands
Several manufacturers produce solar tiles, though availability in Ireland varies significantly:
| Brand | Type | Available in Ireland? | Notes |
|---|---|---|---|
| Tesla Solar Roof | Glass tile with embedded PV | No | US-only. No plans for Ireland announced. |
| Marley SolarTile | Concrete tile with monocrystalline cells | Limited | Available through UK/Irish roofing distributors. |
| Wienerberger (Koramic) | Integrated clay tile PV | Limited | Wienerberger has Irish presence via Roadstone, but solar tiles not widely marketed here. |
| GB-Sol Solar Slates | Slate-look PV tile | Limited | Welsh manufacturer. Designed to mimic natural slate — relevant for Irish slate roofing tradition. |
| Freesuns | Integrated solar slate | Limited | European manufacturer, available through specialist importers. |
The honest reality: as of 2026, solar tiles remain a niche product in Ireland. Most Irish solar installers do not stock or fit them. If you’re set on solar tiles, expect to work with a specialist roofer alongside a solar installer.
Solar tile costs in Ireland
Solar tiles are significantly more expensive than conventional panels. The premium is partly offset if you’re already paying for a new roof, since the tiles replace materials you would be buying anyway.
| System size | Solar tiles (est.) | Traditional panels (est.) | Difference |
|---|---|---|---|
| 2 kWp (5–6 tiles active) | €8,000–€12,000 | €4,500–€5,500 | +80–120% |
| 4 kWp (typical home) | €16,000–€24,000 | €6,000–€9,000 | +150–170% |
| 6 kWp (larger home) | €24,000–€36,000 | €9,000–€11,500 | +160–210% |
Prices are estimates and include materials plus installation. The SEAI solar PV grant of up to €2,100 applies to solar tile systems, but covers a much smaller percentage of the total cost compared to traditional panels.
Why are solar tiles so much more expensive?
- Manufacturing — each tile integrates PV cells, wiring, and weatherproofing into a single unit, which is more complex to produce than standard panels
- Full roof coverage — you need both active (generating) and inactive (matching) tiles to cover the entire roof
- Installation — requires both roofing and electrical expertise, often two separate trades
- Limited supply — low competition in Ireland means higher prices and fewer installer options
When the cost gap narrows
If you’re already planning a full re-roof (typically €8,000–€15,000 depending on roof size and materials), the incremental cost of solar tiles over conventional slates/tiles is considerably less — since you’re replacing roofing you would be paying for anyway. In this scenario, solar tiles become much more competitive.
Availability in Ireland
Solar tiles are not widely available in Ireland as of 2026. Here’s the reality:
- No Tesla Solar Roof — Tesla has not expanded their Solar Roof product beyond the US and limited pilot markets. No Irish installers are certified for it.
- Few specialist installers — most SEAI-registered solar installers work exclusively with conventional panel systems
- Import required — most solar tile products would need to be sourced from UK or European manufacturers
- Two-trade installation — you’ll typically need a roofing contractor and a solar electrician working together
If you’re interested in solar tiles, your best starting point is contacting a roofing contractor who has experience with BIPV products, or reaching out to manufacturers like Marley or GB-Sol directly for Irish distributor information.
Solar tiles vs solar panels
For most Irish homeowners, conventional solar panels remain the better choice. Here’s a direct comparison:
| Factor | Solar Tiles | Solar Panels |
|---|---|---|
| Cost per kWp | €4,000–€6,000+ | €1,500–€2,200 |
| Efficiency | 10–15% typical | 20–22% (monocrystalline) |
| Appearance | Flush with roofline, invisible | Visible panels and racking |
| Payback period | 15–25+ years | 6–10 years |
| SEAI grant | Eligible (up to €2,100) | Eligible (up to €2,100) |
| Irish availability | Very limited | Widely available |
| Installation | Full roof replacement needed | Mounts on existing roof |
| Maintenance | Harder — individual tile replacement | Easier — panel swap is straightforward |
| Wind resistance | Excellent — flush with roof | Good — but uplift risk in storms |
| Planning permission | Easier in conservation areas | May face objections in ACAs |
Planning permission for solar tiles
Solar tiles have a significant planning permission advantage over conventional panels in certain situations:
Standard homes
Solar tiles are exempt from planning permission under the same rules as conventional panels. Because they sit flush with the roof (no projection above the surface), they easily meet the requirement that panels must not project more than 15cm above the roof plane.
Conservation areas (ACAs)
This is where solar tiles shine. In Architectural Conservation Areas, planners may refuse conventional raised panels that alter the roofline. Solar tiles preserve the roof’s character and are far more likely to receive approval.
Protected structures
Listed buildings require planning permission for any external alteration. Solar tiles that replicate the appearance of the original slate or tile are more likely to be granted permission than raised panels.
Streetscape-sensitive areas
In estates or streets where visual uniformity matters, solar tiles avoid the aesthetic objections that sometimes arise with conventional panel installations.
When solar tiles make sense
Solar tiles aren’t for everyone — and for most Irish homes, conventional panels deliver far better value. But there are specific situations where solar tiles are worth considering:
New build
If you’re building from scratch, solar tiles can be specified as part of the roof design from day one — no retrofit, no separate installation.
Full re-roof
If your roof needs replacing anyway (€8,000–€15,000+), the incremental cost of solar tiles over conventional slates narrows significantly.
Conservation area
If you live in an ACA or a protected structure where conventional panels would be refused or would alter the building’s character.
For everyone else
If you have a standard roof in good condition, conventional solar panels are the clear winner. They cost a third of the price, are more efficient per square metre, have a 6–10 year payback period, and are widely available from dozens of SEAI-registered installers across Ireland.
SEAI grant for solar tiles
The SEAI solar PV grant of up to €2,100 applies to solar tile systems. The grant covers solar PV installations generally — there is no restriction on the mounting method or whether the PV is building-integrated.
- Your home must have been built before 2021
- You must use an SEAI-registered installer
- The system must meet SEAI technical standards
- Grant amount: €900 for 1–2 kWp, €300 per additional kWp up to €2,100 total
Practical note: finding an SEAI-registered installer who will fit solar tiles may be difficult, as most registered installers work exclusively with conventional panel systems.

Frequently Asked Questions
Are solar tiles available in Ireland?
Very limited. Tesla Solar Roof is not available in Ireland. Some European brands like Marley SolarTile and GB-Sol solar slates can be sourced through UK/European distributors, but very few Irish installers actively offer solar tile products. You'll likely need a specialist roofer working alongside a solar electrician.
Are solar tiles eligible for the SEAI grant?
Yes. The SEAI solar PV grant of up to €2,100 applies to solar tile (BIPV) systems. The same eligibility rules apply — your home must be built before 2021 and you must use an SEAI-registered installer. However, the grant covers a much smaller percentage of the higher total cost.
How much do solar tiles cost in Ireland?
Solar tiles typically cost €4,000–€6,000+ per kWp installed, compared to €1,500–€2,200 per kWp for conventional panels. A 4 kWp solar tile system would cost roughly €16,000–€24,000, versus €6,000–€9,000 for standard panels. The gap narrows if you're already paying for a full re-roof.
Are solar tiles as efficient as solar panels?
No. Solar tiles typically achieve 10–15% efficiency, compared to 20–22% for modern monocrystalline solar panels. You need more roof area covered with solar tiles to generate the same output as a smaller conventional panel array.
Can I get Tesla Solar Roof in Ireland?
No. As of 2026, Tesla has not expanded its Solar Roof product to Ireland or the wider European market. No Irish installers are certified for Tesla Solar Roof installation. There are no announced plans for an Irish launch.
Do solar tiles need planning permission in Ireland?
Solar tiles follow the same planning exemption rules as conventional panels, but they're actually easier to get approved in sensitive areas. Because they sit flush with the roof (no projection), they easily meet exemption criteria. In conservation areas (ACAs) and for protected structures, solar tiles are far more likely to receive approval than raised panels.
How long do solar tiles last?
Most solar tile manufacturers offer 25–30 year warranties. As a roofing product, they need to match the longevity of conventional tiles or slates. The PV cells will degrade gradually (typically 0.5% per year), similar to conventional panels.
Should I get solar tiles or solar panels?
For most Irish homeowners, conventional solar panels are the better choice — they're a third of the price, more efficient, widely available, and have a 6–10 year payback. Solar tiles only make sense in specific situations: new builds, full re-roofs, or properties in conservation areas where conventional panels would face planning objections.
