Integrated solar roofing
Easily meet RE2020 French environmental regulations without compromising on aesthetics, using integrated solar roofing tiles or interlocking panels. We partner with Solarstone and Metigla - Roofit.Solar to offer to France a range of integrated solar roofing products with outstanding energy efficiency and low carbon impact.
Instead of adding bulky panels on top of a finished roof, these systems embed photovoltaic technology directly into the roofing material, delivering a sleek, durable, and architecturally seamless solution that boosts renewable energy production from day one. When the cost of an integrated solar roof is no more than a traditional roof with solar panels on top, it really is a no-brainer.
With integrated solar roofing, homeowners can meet or surpass RE 2020 performance targets more easily - reducing primary energy consumption, lowering carbon indicators, and future-proofing the home against rising energy demands and upcoming EU solar requirements. The result? A beautiful, modern roof that works hard behind the scenes, cutting energy bills and increasing property value while maintaining full architectural freedom.
Be ahead of the curve - from 2030 EU rules (Energy Performance of Buildings Directive / EPBD) will require solar on all new residential buildings (where feasible). Integrated solar isn’t an add-on. It’s the new standard that ensures your roof pays for itself and doesn’t cost the planet.

Reducing primary energy consumption and carbon impact from day one, it makes complying with RE2020 a breeze. With Metigla - Roofit.Solar, your roof doesn’t just protect your home - it powers it, adds value, and defines the next generation of sustainable design.
Benefits
-
Using monocrystalline Mono PERC solar cells, Roofit Solar maintains excellent output even in low-light conditions. Its strictly positive power tolerance and high low-light performance help maximize annual generation, even in northern European climates
-
A well-sized Roofit Solar installation can generate thousands of kWh/year of electricity. When paired with batteries or smart export tariffs, this can significantly reduce reliance on grid electricity and cut annual utility bills, with surplus energy potentially sold back to the grid
-
With nearly invisible integrated cells and sleek black standing seam panels, the system meets strict aesthetic standards, often gaining approvals even on protected or heritage buildings where conventional PV arrays would be restricted
-
Because Roofit Solar installs like a conventional standing seam roof, it reduces labour and material costs compared with separate solar panels plus roof deck, potentially shortening construction time and lowering overall project cost.
FALT SOLAR by Roofit.Solar is a building-integrated photovoltaic (PV) product, that combines roof and solar panels into one (2-in-1), and is installed as easily as a regular standing seam roof.
Each FALT SOLAR module uses a ‘plug & play system to connect the cables, and with the help of our design software, each project will obtain a clear plan of how to connect the cables on the roof. -
Constructed from pre-painted steel (0.5 mm) with a PUR50 µ coating, the Roofit Solar system is lightweight (~15.5 kg/m²) yet robust. It achieves Class A fire safety and withstands hail at speeds up to ~165 km/h, making it suitable for diverse French climates
-
The system comes with a 25-year linear power warranty, ensuring that panels produce at least 80 % of their rated output after 25 years. This gives homeowners confidence in long-term energy production and predictable economic returns.
-
Manufactured and tested to rigorous IEC standards (including IEC 6215, 61730, 62716 and 61701), Roofit Solar panels combine European quality assurance with real-world durability
Solarstone full solar roof
The Solarstone Full Roof System redefines how solar is integrated into residential architecture. Designed as a true building-integrated photovoltaic (BIPV) solution, it replaces conventional roofing entirely, transforming the whole roof into a clean, efficient energy generator. Solarstone panels sit flush within the roof plane, delivering a sleek, contemporary finish with no visible frames, rails, or add-on panels.
Beyond aesthetics, the system offers high-performance solar generation that helps new homes meet and exceed RE2020 energy targets, reducing primary energy consumption and long-term running costs.
By combining weather protection and electricity production in one durable system, Solarstone simplifies construction while improving overall energy performance. The result is a future-ready roof that adds real value, lowers energy bills, and integrates seamlessly with modern architectural design.
Benefits
-
Rather than retrofitting solar into or on top of a traditional roof, Solarstone is a true building-integrated photovoltaic (BIPV) roof, where every roof tile is designed for solar generation. This delivers a fully unified surface with no rail systems or visual breaks - ideal for high-end architectural projects and sensitive planning zones.
-
Because Solarstone tiles replace the roof covering entirely, every square metre contributes to power generation - unlike systems where only selected roof zones with panel racks are productive. This increases total annual generation capacity.
Solarstone’s optimized module design and tile layout allow for more active cell coverage per square meter than many standing seam systems, resulting in a higher potential kWh output per roof area, especially on complex or multi-directional roofs
-
Solarstone gives architects and homeowners a smooth, tiled look with integrated solar. Unlike visible standing-seam panels, the finish is monolithic and timeless, enhancing curb appeal and complementing both modern and traditional façades
-
Solarstone integrates waterproofing, insulation interface, and solar generation in one seamless layer, reducing the overlap and integration challenges that can arise with panel + roof combinations like standing seam + modules.
Each solar module is accessible, making replacements straightforward without affecting the rest of the roof. This modular approach ensures the longevity and efficiency of your solar roof.
-
The Solarstone system accommodates complex roof geometries, hips, valleys, and multiple orientations without breaking visual continuity. This means high performance even on roofs that are less optimal for standard panel layouts, delivering greater real-world energy production across diverse designs
Solarstone tiled roof
The Solarstone Tiled Roof System is engineered for projects that require selective, high-performance solar generation while retaining the appearance and detailing of a traditional tiled roof. Unlike a full BIPV roof where every surface is solar-active, the tiled system allows solar modules to be strategically placed only on optimal roof zones - maximising yield on south-facing pitches while maintaining standard tiles elsewhere.
This approach delivers excellent kWh output per installed square metre, reduced system cost, and greater flexibility for complex roof layouts, dormers, hips, and planning-sensitive elevations. Solarstone tiles integrate flush with surrounding roofing materials, ensuring continuous waterproofing and clean roof lines without rails or over-roof mounting systems.
For many residential projects, the tiled solution provides the best balance of performance, aesthetics, and budget, delivering RE2020-aligned energy production without committing the entire roof surface to photovoltaic generation.
Benefits
-
Unlike a full solar roof, the tiled system concentrates photovoltaic tiles only on high-yield roof areas (typically south or south-west facing pitches). This improves energy output per installed module and avoids installing solar where shading or orientation would reduce performance
-
By limiting solar tiles to optimal zones, the system delivers strong kWh production per square metre of solar installed, often achieving similar annual output to larger full-roof systems but with fewer photovoltaic elements
-
The tiled approach significantly lowers material and installation costs compared to a full solar roof by combining standard roofing tiles with integrated solar tiles only where they add measurable energy value
-
Solarstone’s tiled system adapts easily to hips, valleys, dormers, skylights, and multi-pitch roofs, without forcing all surfaces to be solar-active. This simplifies detailing and preserves architectural intent
-
Flush-mounted solar tiles maintain the appearance of a traditional tiled roof, making this system particularly suitable for planning-sensitive areas, renovations, and developments where a full solar roof may be visually restrictive
-
With solar limited to defined roof zones, maintenance, replacement, or future system expansion is simpler and more cost-effective than with a full solar roof, while still delivering meaningful RE2020-aligned energy performance

Every project is different, but when the cost of an integrated solar roof is no more than a traditional roof with solar panels on top, it really is a no-brainer.
-
In the Haute Savoie we have teams of roofers and electricians who work together to install the product. Elsewhere in France we will liaise and consult with your local teams to ensure smooth installation. All photovoltaics must be installed by a registered solar roofer.
We support projects from early design through installation with technical advice, system sizing, and coordination with other building elements
-
Integrated solar roofs are often more acceptable in protected or planning-sensitive zones because they maintain the appearance of the roof rather than adding external equipment.
-
Absolutely. Solar roofs can be paired with battery storage, EV chargers, and smart energy management systems to maximise self-consumption.
