At the Helmholtz Zentrum Berlin, a living lab has been constructed 2021 with building integrated photovoltaics in colored panels on three of the four sides (South, West and North), with a total nominal power around 50 kW. For research purposes, the ventilated curtain wall facades, with varying insulation situations behind the PV modules, are extensively monitored 24/7 for building specific parameters such as temperature and air flow, next to the more usual electrical, optical and meteorological data. For a new ensemble of research buildings, on the same location, a first building has been designed by the prize-winning architects and is planned for delivery in 2025. Part of this building will be a number of metal façade elements, which are very well suited for and planned as testing areas for flexible solar modules. This part of the living lab will offer a perfect testing area for the Solar TAP products and will allow for a one-to-one comparison to more traditional PV elements but will also highlight the additional value that Solar TAP´s flexible PV technology can offer.
