The building is a mountain chalet surrounded by the impressive scenery of the South Tyrol dolomite mountain ridges. It can be considered a modern interpretation of the old ‘Paarhof’, the traditional kind of farm building typical for South Tyrol, built with a local natural material such as pine wood and white Dolomite concrete (Leitner Electro Srl). A BIPV system is integrated on the wooden roof of the chalet.

The BIPV system is made of black modules replacing the conventional roof boards, in a way that the plant blends in very well with the dark roof.

The chalet is certified ‘CasaClima A’ and achieved the nZEB (nearly Zero-Energy Building) target, due to the exploitation of solar and geothermal energy and the employment of energy-efficient building solutions. The photovoltaic system was calculated to produce around 6,592 kWh per year. It is able to cover the building’s electric consumption for the ventilation system and the heat recovery. Around an 80% of the produced photovoltaic electricity is self-consumed. The system has access to the net metering scheme (Scambio sul Posto) (Leitner Electro Srl).

The 25 photovoltaic modules (Aleo Solar S_79 SOL) are mounted with special aluminium Solrif profile frames and fixed to the substructure with special mounting clamps, used to brace two modules to their frames in the overlapping area. This system ensures weather tightness thanks to the special horizontal interlock of the modules’ profile frames and the additional rubber lip placed between the overlapping module edges. The modules are naturally back ventilated, due to the distance between the modules and the roof. For safety reasons, the wiring and the connectors are placed in a grid gutter, fixed on fire-resistant plasterboard that separates the modules from the wooden parts of the roof.

From the beginning, the client, Arch. Armin Pedevilla, included the PV plant into the building project, driven by the purpose of creating a high-energy efficiency building, able to produce the energy required using most of the on-site available renewable energy sources. Once the economic feasibility was verified through simplified calculations, he confirmed the installation of the plant. The PV panels were architecturally integrated into the roof with the main goal of reaching a high level of aesthetic quality, matching the building’s dark painted oak exterior (Leitner Electro Srl).

The photovoltaic technology is integrated combining contemporary with traditional design. Simple standard PV modules are placed on the roof as if they were conventional roofing components blended into the dark wood boards, making the building a great example of photovoltaic integration with high replication potential. This example shows that reaching an overall high quality of a BIPV system requires a careful design, with care for details and sensitivity to the surrounding, but it does not always require specific custom-made products.
