SolTech Facade

-A solar cell that is a “cold“ facade




SolTech Energy offers a solar cell façade that replaces other facade materials, such as: brick, metal platel or facade panels. SolTech Facade, just as with these other facade materials, is mounted with an underlying layer of ventilated air. Such a ventilated solar cell installation does not provide a building with isolation but rather is needed to promote both the performance of the solar cells as well as the building itself. SolTech Facade, which produces electricity, is priced marginally higher than a comparable standard façade, but its energy payback (break-even) time (EPBT) is notably short, leaving many years of electricity income/cost reduction, free-and-clear.

SolTech Facade is a reveolutionary concept whereby solar cell technology is built into, for example, the glass façade of a building. With this product you get welcome light passing through a roof or wall – and at the same time – the capacity to turn sunlight into electricity. Both black/variously colored and transparent surfaces produce between 100 – 113 Wp/m². The solar cell offers levels of transparancy ranging from 0 to 90%, with the effect being linear to the level of transparency: A solar cell with 50% transparency has a 50% effect of 113 Wp.

SolTech Facade is mounted using horizontal aluminum profiles that, together with the solar cells, lend a striking, clean-styled appearance to a building’s façade. The solar cell aluminum profiles are mounted without the use of special tools, which allows the installation to go quickly.

The size of the solar cell profiles is 1200×600 mm and they can be mounted both horizontally and vertically in straight rows or with displaceable joints. The solar cells have been created based on thin-film technology and their uniform black design clearly sets them apart from standard solar cells. SolTech Facade delivers 123 Wp/kvm.

All glass surfaces absorb usable solar energy. SolTech Facade is a semi-transparent thin-film solar cell product that can be built into such external building surfaces and combine solar energy with sun shading. The product can be ordered with different levels of transparency, either as replacement for ordinary glass or as a glass wall. This means you can get significant sun shading, simultaneous with the production of electricity. This concept is suitable to everything from shop windows to enclosed winter gardens. For buildings requiring isolation, SolTech Facade can also be installed as isolation glass. SolTech is able to supply an isolation glass with energy requirements ranging down to the passive house level. It is the customer’s needs that determine how we build the glass.

Solar cells, window glass and sun shading no longer have to be regarded as separate parts of a building. In one and the same SolTech Energy product you have window glass, with sun-shading effect as desired, that simultaneously functions as a producer of electricity. SolTech ST is easily installed in a glass roof or glass facade by making use of Sapa or Wicona’s respective profiles. All Sapa/Wicona product centers in the Nordic and Baltic regions, as well as those in Poland, are possible installers, thereby facilitating the realization of a building owner or architect’s vision, considerably. The product can be installed in a known profile system and built by product centers that are familiar with working in the Swedish construction market.

The aluminum profile has been developed inhouse with the help of Sapa Building Systems and is anodized or lacquered in black. SolTech Facade is complemented with inactive glass as “fitting” pieces. This makes it possible to create beautiful, integrated facades with SolTech Facade even on existing buildings, no matter the size of the surface. Simply put, this makes it possible for the solar cell to become a building material.
