In 2019, the Brunner-Bapst family built a PlusEnergie single-family home with the highest self-energy supply of all Swiss solar prices to date. The generous, east-west oriented gable roof protects against wind and weather and produces 40,200 kWh per year, an energy surplus of 817%.
With its clean lines, large glass facades and wooden materials, this new house blends in well with the picturesque landscape. The PV installation, which covers the entire roof, adopts a modern design, which is designed to resemble homogeneous coloured scales.

The wooden gable roof construction of this new building is covered by a PV installation over its entire surface. Between the copper ridge and eaves details, the homogeneously black PV modules run through the roof surfaces. This creates an appearance that is in keeping with the townscape and also blends in with the picturesque landscape.
