Pulse, 1m x 6.6m, polycrystalline solar cells/aluminum/glass/micro inverters, 2013 Four solar modules installed on the roof of the Stedelijk Museum Buro Amsterdam (SMBA) produced solar energy during the period of the exhibition. This energy was fed into the grid, reducing the energy consumption of the art space. The solar panels were connected to a computer equipped with software, measuring the amount of the energy produced. The energy production is visualized through graphics on a monitor displayed within the exhibition space. Creating geometrical patterns by using different colors of polycrystalline solar cells, the ornaments visible on the surface of the solar modules depict a heartbeat as detected by an electrocardiogram.
