Soltecture proves: Solar construction enables energy-independent, attractive living and mobility

Thin-film modules with award-winning design used in flagship project from Vattenfall, Volvo and A-hus

The One Tonne Life-Project

Together with its partners Vattenfall, Volvo and A-hus, the Berlin solar module manufacturer Soltecture (formerly Sulfurcell) is setting new standards for sustainable construction: the energy-plus house, which has been purpose built for the One Tonne Life Project with the aim of reducing annual CO2 emissions per capita, is equipped with a heat storage system and 106 Soltecture thin-film solar modules made in Germany. 57 of the modules are integrated into the south-facing elevation and form an elegant, black glass surface, while another 49 modules are installed on the roof. The total rated capacity of the Soltecture thin-film modules amounts to 6.5 kilowatt peak (kWp).

Dr. Nikolaus Meyer, CEO and founder of Soltecture explains: “Here the solar modules become the architectural highlight. They are deployed as facade and roof elements and replace passive construction materials. That is building for the future. This is solar construction.” The building-integrated solution transforms the otherwise unused surfaces into small, decentralised power plants, which not only supply clean energy but also help to reduce costs. The four-member Swedish test family, who lived in the prototype house for the last six months, drew all the necessary electricity and additional heat from the solar power system in combination with a small solar thermal system on the carport. During the course of the year, the PV system actually generates considerably more energy than is required in the home. The surplus energy is used for the electric car or is fed into the national grid.

The conclusion after completing the six-month project: With the help of energy-efficient, cutting edge building services technology and the integrated solar power system, the family managed to reduce their CO2 emissions from an average of 7 tonnes per head to 1.5 tonnes.
