Solar panels on green roof. This experimental roof was one of the first to combine solar panels (arrays of photovoltaic cells) and rooftop vegetation. Such combined roofs are now common as the planting assists in the efficient summer working of the photovoltaic array by reducing the local temperature via transpiration and evaporation. This is a roof at the ufa-Fabrik Berlin, a former film centre and now an international centre for culture and ecology. The garden was planted from 1980, with the solar panels added in the 1990s. Photographed in 2014, in Berlin, Germany.
