Photovoltaic Coppo: what it is, how it works, and where it can be installed
18 March 2026
Generating clean energy without compromising the roof's aesthetics: this is the problem that the photovoltaic coppo solves. For decades, photovoltaics remained excluded from historical centers, medieval villages, and any building subject to landscape or architectural constraints; simply because the only available alternative was solar panels that visually altered the roofing.
The photovoltaic coppo changes this equation: it integrates into the roof like a standard terracotta coppo, produces energy from sunrise to sunset and—crucially—is designed to be approved by the Heritage Authorities.
In this guide, we explain how it works, where it can be installed, how much it costs, and why it differs from any other photovoltaic solution on the market.
What is the photovoltaic Coppo and how it differs from a traditional panel
The photovoltaic Coppo is a roofing element that serves a dual function: it protects the building like a traditional Coppo and produces electricity thanks to photovoltaic cells integrated into the curved glass.
The difference compared to classic solar panels is structural, not just aesthetic:
- Traditional panels are mounted on top of the existing roof, creating an additional layer that is visually foreign to the building. They require support structures, are recognizable from a distance, and are not permitted in areas subject to landscape constraints.
- The photovoltaic Coppo replaces existing tiles and blends into the roof covering indistinguishably. It adds no volume, creates no glare, and does not alter the roofline.
In short
A photovoltaic Coppo is not a solar panel installed on the roof — it is the roof itself that generates energy.
How it works: technology, materials, and energy production
The Lumyra photovoltaic Coppo is made of curved tempered glass with photovoltaic cells integrated directly into the material. The outer surface is treated with a matte textured coating that faithfully reproduces the texture and color of traditional terracotta — available in variants such as natural terracotta red, light pink, and warm gray.
Energy production in all conditions
The photovoltaic Coppo cells are optimized to generate energy not only with direct sunlight, but also in conditions of:
- Diffuse light: cloudy days, partial sky coverage.
- Reflected light: from adjacent surfaces such as water, other buildings, or light-colored flooring.
- Low winter irradiation: months with a reduced solar angle.
Each group of Coppo elements operates independently: if one element is damaged, the rest of the system continues to produce without interruption.
Main technical specifications
The photovoltaic Coppo features the following technical characteristics:
- IP68 Protection: total resistance to water, rain, and snow.
- Self-extinguishing materials: certified against fire propagation.
- Drill-free installation: traditional "coppo/sottocoppo" (over/under) method, ensuring no damage to the roof covering.
- Anti-reflective finish: no glare effect, compatible with restricted heritage contexts.
Regulatory Note
Each Heritage Authority (Soprintendenza) evaluates applications independently. Approvability depends on the specific characteristics of the building and its context.
Photovoltaic Coppo in historical centers and listed buildings: is it possible to install it?
This is the most frequent question, and the answer is yes, under the right conditions. The photovoltaic Coppo is specifically designed to be the permissible photovoltaic solution in contexts where any traditional panel would be excluded.
The problem of photovoltaics in protected contexts
In Italy, buildings subject to landscape, historical-artistic, or architectural constraints (pursuant to Legislative Decree 42/2004 — Cultural Heritage Code) require authorization from the Heritage Authority (Soprintendenza) for any intervention that modifies the external appearance. In most cases, traditional photovoltaic panels are denied because they alter the roof's profile and introduce an element foreign to the building's morphology.
This effectively excludes a huge portion of Italian building heritage from the benefits of photovoltaics: historical centers, medieval villages, historic villas, Art Nouveau buildings, and prestigious courtyards.
Why the photovoltaic Coppo is approvable
The Lumyra photovoltaic Coppo overcomes this barrier for three specific reasons:
- Identical aesthetics to traditional Coppo: the matte textured coating reproduces the texture of terracotta. From a distance — and often even up close — it is indistinguishable from a normal Coppo.
- Anti-reflective finish: no unwanted light effects that could alter the perception of the roof or disturb the urban context.
- No structural modification: it is installed like a conventional Coppo, without piercing the roof membrane and without adding superstructures.
Advantages of the photovoltaic Coppo for residential and prestigious buildings
Choosing the photovoltaic Coppo means opting for a solution that combines energy performance, safety, and architectural value in a single element.
For the owner of a historic or listed building
Finally, it is possible to access the benefits of photovoltaics without compromising the property’s appearance, without being denied authorization by the Heritage Authority (Soprintendenza), and without devaluing the aesthetic worth of a prestigious building heritage.
For those building or renovating
The photovoltaic Coppo allows for the integration of energy production into the architectural project from the very beginning, transforming the roof from a pure cost into an active surface that generates value over time.
For the professional (architect, surveyor, energy manager)
A solution with a complete technical data sheet, certified anti-reflective finish, and installation according to traditional methods — all the necessary elements to support a permit application
Frequently Asked Questions (FAQ) about the photovoltaic Coppo
Is the photovoltaic Coppo allowed in historical centers?
Yes. The Lumyra photovoltaic Coppo is designed to be approved by the Heritage Authority (Soprintendenza) thanks to its matte anti-reflective finish that does not alter the appearance of the traditional roof. Each application must nonetheless be evaluated on a case-by-case basis with the local competent Authority.
How much does a photovoltaic Coppo cost?
The cost varies based on the roof surface area, exposure, and system configuration. Contact Lumyra Energy for a personalized quote.
How is the photovoltaic Coppo installed?
Installation is carried out using the traditional "coppo/sottocoppo" (over/under) method, without drilling into the roof membrane. No structural intervention is necessary: the photovoltaic Coppo replaces existing tiles in the same position, following the same techniques.
Does it produce energy even with cloudy skies or in winter?
Yes. The Lumyra photovoltaic Coppo is optimized to produce energy even in conditions of diffuse and reflected light, not just with direct solar radiation. Production continues during winter months and on cloudy days, with a natural reduction proportional to the available irradiation.
What is the difference between a photovoltaic Coppo and a traditional solar panel?
The photovoltaic Coppo integrates into the roof by replacing existing tiles, without altering the aesthetics of the covering. Traditional solar panels are placed on top of the existing roof with visible support structures. The photovoltaic Coppo is permissible in restricted areas where traditional panels would not be authorized.
Is it compatible with all types of roofs?
The photovoltaic Coppo is ideal for terracotta tile roofs, typical of traditional Italian construction. Installation requires a preliminary assessment of the roof structure, pitch, and exposure. Contact the Lumyra team to verify compatibility with your building.
Do you want to know if the photovoltaic Coppo is suitable for your building?
The Lumyra Energy team will analyze your specific situation: available surface area, roof orientation, and any potential landscape constraints. Contact us for a technical inspection and a personalized quote.
