Scandinavian Simplicity in Electrotile Solar Tiles

Have you ever wondered why Scandinavian houses look so harmonious? The secret lies in simplicity and functionality - the two foundations of Nordic design. When we started working on the solar roof of the future, it was these principles that became our inspiration. Unlike traditional photovoltaic installations that disrupt the architecture of a building, we wanted to create a solution that is both efficient and beautiful. Learn the story of how Scandinavian design philosophy helped us revolutionize solar roofs.

Challenge: Reconciling technology with aesthetics

Imagine a beautifully designed house - a harmonious body, carefully selected materials, thought out every detail. And now imagine that you install traditional photovoltaic panels on its roof. Large, black rectangles mounted on aluminum racks completely disrupt the architecture of the building. It's like putting on sports shoes to an elegant suit.

This is the challenge facing architects and investors today. On the one hand, rising energy costs and concern for the environment are encouraging the installation of photovoltaics. On the other - no one wants to spoil the appearance of their dream home. In addition, traditional photovoltaic installations often require interference with the roof sheathing, which can lead to leaks and loss of warranty.

The problem becomes even more acute in the context of new EU regulations. From 2029, all new residential buildings will have to be equipped with photovoltaic systems. This means that architects and manufacturers need to find a way to elegantly integrate solar technologies into architecture.

Inspiration from Scandinavia

We were looking for a solution in Scandinavia - not by chance. It is Nordic designers who have been showing the world how to combine functionality with beauty for decades. The Scandinavian design philosophy is based on several key principles that also work well in the context of solar roofs.

First of all, simplicity. Scandinavians know that true elegance does not need frills. Clean lines, harmonious proportions and thoughtful details create timeless beauty. That's why our solar roofs are designed to be inconspicuous — they are an integral part of the building's architecture.

Secondly, the quality of materials. The harsh climate of Scandinavia forces the use of durable and reliable solutions. There is no room for compromises or cheap replacements. In our solar roofs we use materials of the highest quality - steel from certified Scandinavian mills, glass resistant to hail and extreme weather conditions, connectors tested in the most demanding conditions.

Thirdly, respect for the environment. The Scandinavian approach to design always takes into account the ecological aspect. It's not just about the materials themselves, but also about their longevity and recyclability. Our solar roofs are designed to last for decades, minimizing the carbon footprint associated with manufacturing and component replacement.

Importantly, Scandinavian solutions always take into account the local context. Roofs must be adapted to heavy snowfall, strong winds and large temperature differences. The same challenges apply to photovoltaic installations in our climate. Therefore, the adaptation of proven Scandinavian roof technologies for integration with photovoltaics was a natural choice.

The Evolution of Scandinavian Roofing Solutions

The story of Scandinavian roofing solutions is a fascinating story of how the harsh climate and limited resources led to extremely efficient technologies. It all started with a simple observation - in the Nordic countries, the roof must above all effectively protect against extreme weather conditions.

Traditional ceramic tile roofs, popular in southern Europe, did not perform well in the Scandinavian climate. In winter, freezing water shattered the roof tiles, and the weight of the lingering snow required a very strong load-bearing structure. That is why the Scandinavians began to experiment with light metal coverings.

The first breakthrough was the development of sheet metal seam technology. This solution, initially used mainly on the roofs of churches and public buildings, has proven to be extremely durable and resistant to extreme conditions. Moreover, it allowed to cover the roof of virtually any shape and angle of inclination.

The next milestone was the development of modular roof tiles. Scandinavian engineers have noticed that by combining the advantages of sheet metal (lightness, durability) with the aesthetics of traditional tile, they can create a product that perfectly meets the needs of modern construction. The modular system not only accelerated the assembly, but also minimized the risk of execution errors.

This evolution of roofing technologies has given us a solid foundation to create integrated photovoltaic systems. We have used proven solutions in the field of sealing, ventilation and thermal stress compensation, adding modern solar cells to them. Thus, a system was created that not only produces energy, but, above all, is a reliable roofing material.

Scandinavian precision in every detail

In Scandinavia, it is said that the devil is in the details. This saying perfectly captures the philosophy that guided us when designing the eTile system. Every, even the smallest element has been carefully thought out and tested.

Take, for example, the panel fastening system. In traditional photovoltaic installations, aluminum mounting rails screwed to the roof are used. We used the proven latch technology, used in the seam plates. Thanks to this, the installation is not only faster and safer, but also completely invisible from the outside.

Another example of attention to detail is the ventilation system. In the Scandinavian climate, proper ventilation of the roofing is crucial for its durability. Therefore, we have developed special ventilation ducts integrated into the design of the panels. They not only ensure adequate moisture dissipation, but also help to cool the photovoltaic cells, increasing their efficiency.

We also paid special attention to the aesthetics of the connections. In traditional installations, cables and connectors are often visible or hidden in unsightly troughs. In our system, all electrical connections are hidden in specially designed channels, completely invisible from the outside. It's not just a matter of appearance - it's also more safety and weather protection.

Technology that will not go out of style

Scandinavian design is famous for its timelessness. The same principle guided us when designing the eTile system. We didn't want to create a product that would look outdated in a few years. Therefore, we focused on simplicity and purity of form.

Our panels are not trying to pretend to be something they are not. Instead, they expose the natural aesthetics of the materials - the noble matte of solar glass, the precise lines of the joints, the subtle play of light on the surface. It is a design that does not scream “look, here is photovoltaics”, but integrates elegantly into the architecture of the building.

This design philosophy makes our solar roofs look just as good in 20 or 30 years. Because true elegance never goes out of style.

The road to innovation

We use carefully selected the most innovative roofing technologies that we have integrated into solar cells:

eTile Classic — is integrated into the modular roof tile. Sheet metal tile comes from Scandinavia. The Ruukki company developed this technology, which was subsequently distributed by other manufacturers. It is characterized by the fact that for its production is used coated steel sheet with high strength, anti-corrosion and waterproof qualities. For sheet metal, manufacturers often give 40-50 years of warranty, with proper use after so many years it should continue to fulfill its function 100% and not discolor. Sheet metal tile offers several significant advantages over ceramic tile. First of all, it is significantly lighter - it weighs about 5-6 kg/m2 compared to 40-50 kg/m2 for ceramic tiles, which means less load on the roof structure and the possibility of using lighter rafters.

The second advantage is faster and easier installation, since the sheet tile is laid with sheets and not with individual elements like ceramic tile.

Thirdly, sheet metal tile is more resistant to mechanical damage and does not crumble over time like ceramics.

Fourthly, it is much more resistant to extreme weather conditions - due to its flexibility and material strength, it better tolerates strong winds, hail and sudden temperature changes that can cause ceramic tiles to crack.

The fifth advantage is the possibility of using on roofs with a smaller angle of inclination - already from 12-15 degrees, while ceramic tile requires a slope of at least 30-35 degrees, which limits the design possibilities and increases the height of the building.

In addition, it is worth mentioning that the sheet tile does not require impregnation or additional maintenance treatments that are necessary for ceramic tiles.

An additional, seventh advantage of sheet metal tile is a much greater variety of available designs and shapes, including trendy, minimalist models such as flat sheet metal tile - this is due to the fact that creating a new matrix for the production of sheet metal tile is many times cheaper than designing and implementing a new pattern of ceramic tile, so manufacturers can react faster to changing architectural trends lower price of sheet metal tile due to cheaper production technology and lower energy consumption, it is often confused with lower standard product, which is confusing, because modern sheet metal tile is a premium product.

eTile Flat - Clip-type standing seam sheet is a modern roofing technology that originates from the Scandinavian building tradition. It is a system that has revolutionized the way sheet roofing is installed.

Firstly, a distinctive feature of this technology is a specially designed snap lock, which allows quick and reliable installation of subsequent sheets of sheet metal - it is enough for the roofer to “click” one sheet into another, without the need for specialized tools or crimpers.

Secondly, this system provides exceptional roof tightness thanks to a double lock and additional seals that protect against blowing snow and rain even in extreme weather conditions, which is especially relevant in the Scandinavian climate.

The third advantage is the ability to compensate for the natural thermal movements of the sheet - the latch system allows microcurrents of the material when expanding and contracting under the influence of temperature changes, without causing the formation of stresses and deformations.

The fourth distinguishing feature is the minimalist aesthetic - the even, vertical lines of the hem create a modern geometric pattern on the roof that blends well with contemporary architecture.

Fifth, this technology allows installation on roofs with a very small angle of inclination - from as little as 8 degrees, which gives architects much more design freedom than with traditional roofing.

The sixth advantage is durability - thanks to high-quality steel with Pural Matt coating and a well-thought-out ventilation system under the sheet metal, these roofs serve without problems for decades, which is confirmed by realizations in Scandinavia.

The seventh distinguishing feature is the possibility of prefabrication of sheets to size at the factory - the panels are cut with an accuracy of a millimeter according to the design, which significantly speeds up the assembly and minimizes the amount of waste at the site.

eTile Karo — solar roof integrated with titanium-zinc sheets.

Titanium-zinc in the diamond system is a unique roofing technology that combines traditional craftsmanship with modern design.

The first and most important advantage is remarkable durability - titanium-zinc forms a natural patina on its surface, which not only protects the material, but over the years acquires a noble matte character. This property allows the roof to serve up to 100 years, which makes it one of the most long-lived roofing materials.

Secondly, this material is completely resistant to corrosion and does not require any maintenance - the natural patina is constantly renewed, “healing” even minor scratches on the surface. This is especially important in urban areas where air pollution can accelerate the degradation of other materials.

The third advantage is the diamond system, that is, square or rhomboid tiles that form on the roof a characteristic pattern of diamonds. This system allows for extraordinary flexibility in design - you can create both classic, symmetrical layouts and modern, dynamic compositions.

The fourth distinguishing feature is the ability to cover even very complex roof shapes with this system - small diamond elements work great on domes, dormers or turrets, where other materials would be difficult to install.

Fifth, titanium-zinc is a completely environmentally friendly material - it is 100% recyclable, and its production requires much less energy than the production of other metals. Moreover, the natural patina does not contain harmful substances and does not pollute rainwater.

The sixth advantage is unique aesthetics - the titanium-zinc surface has a natural, noble texture that changes depending on the angle of incidence of light, creating a living, dynamic surface on the roof.

The seventh advantage is excellent cooperation with modern architecture - the diamond system allows you to create both traditional and very modern forms, and its neutral color scheme blends harmoniously with various facade materials.

eTile Step — it is a system based on sheet metal tile Ruukki Hyygge, a unique product in the roofing sheet market.

Ruukki Hyygge sheet metal tile is a unique system that has introduced a real revolution in the modular sheet metal tile segment. What makes this solution different?

First of all, Hyygge has an innovative modular mounting system, where each panel is fixed at four points, creating an extremely stable construction. Unlike traditional sheet metal tiles, which are installed in rows from bottom to top, Hyygge panels can be mounted both horizontally and vertically, which greatly speeds up the work on the roof.

Another unique feature is the completely flat surface of the panels - the absence of dents and bends makes the roof look like it is covered with high-quality flat ceramic tile. This is due to a specially designed system of joining panels, where the locks are practically invisible from the ground. This minimalist design blends well with modern architecture.

The Hyygge system is also distinguished by its exceptional tightness. Specially designed double locks on all four edges of the panel create an insurmountable barrier to water and snow. Moreover, this system allows the material to work with temperature changes without the risk of sealing joints.

A significant advantage is also a much lower material consumption - thanks to a well-thought-out connection system, there is practically no waste on the roof. Each panel has a useful dimension close to the actual dimension, which means that almost the entire area of the purchased material is effectively used on the roof.

In addition, Hyygge offers a unique solution for roof slab ventilation. Specially designed ventilation ducts in the panels provide optimal air circulation under the roofing, which significantly extends the life of the entire roof structure.

eTile Fusion — a solar roof solution for an existing ridge roof.

The eTile Fusion system is a breakthrough solution for seam roof owners who want to use existing roofing to generate electricity. Let's analyze its main benefits.

The first and most important advantage is the preservation of the warranty on the existing roof. Unlike traditional photovoltaics, which requires invasive installation and drilling of the sheathing, the Fusion system uses special mounting brackets that are clamped at the edges without disturbing the roof structure.

The second advantage is the aesthetics of the solution. Fusion photovoltaic modules are specially designed to perfectly match the width of the hem spacing. Thanks to this, the entire installation looks like an integral part of the roof, and not as an additional structure mounted on it.

The third advantage is the safety of installation. The system uses the technology of “embroidery” - special steel handles that are tested for extreme wind loads. Each module is fixed at four points, which gives remarkable stability even during hurricanes.

The fourth benefit is optimal ventilation. The modules are mounted at a short distance from the roof sheathing, which ensures free air flow. This is crucial both for the efficiency of the photovoltaic system (cooler modules = higher efficiency) and for the durability of the roof.

The fifth advantage is the possibility of quick disassembly. Should there ever be a need for roof maintenance or module replacement, the system can be easily dismantled and reinstalled without damaging the covering.

The sixth advantage is the universality of application. The Fusion system is compatible with most of the popular sheet metal seam systems available on the market - both with single and double standing seam.

The seventh advantage is a long service life. All components of the system are made of stainless steel or aviation aluminum, which guarantees long-term resistance to corrosion and weathering.

The eighth advantage is ease of assembly. Specially designed mounting elements allow for quick and precise installation. An experienced team can mount the system much faster than a traditional photovoltaic installation.

The ninth advantage is flexibility in design. The system allows the installation of modules in different configurations, which allows optimal use of the available roof area and adaptation to individual energy needs.

The tenth advantage is the economic aspect. Although the initial cost of a Fusion system may be slightly higher than a traditional installation, the lack of need to replace the roof and the longer service life of the system make it a more cost-effective solution in the long run.

Summary: The Future of Solar Architecture

Scandinavian simplicity combined with advanced photovoltaic technology has set a new standard in solar architecture. It is no longer just about generating energy - it is about creating buildings that are both beautiful and energy self-sufficient.

Looking ahead, we can see that this trend is only going to get stronger. New EU regulations force the use of photovoltaics in construction, but it is aesthetics and functionality that will decide which solutions are adopted on the market. The houses of the future will not only produce their own energy - they will do it elegantly and imperceptibly.

The eTILE system is proof that solar technology can be an integral part of architecture, not just an addition to it. It is no coincidence that our solution has been recognized with the prestigious Red Dot Design Award - one of the most recognized accolades in the world of design. This award confirms that we have taken the right direction by combining Scandinavian simplicity with innovative technology.

We invite you to discover how Scandinavian design philosophy can change the way you look at solar architecture. Because the future of construction does not have to be a compromise between aesthetics and ecology - it can be a harmonious combination of both aspects.
