Solar technology. Solar heat collectors (black panels) on the roof of a building on the Braamwisch Ecological Housing Estate, part of the Karlshohe Solar Project, Hamburg, Germany. The solar heat collectors absorb the heat from the sunlight, which is used to directly heat water. The water can then be stored as a hot water supply or can be used to heat the building. These buildings also have solar panels (arrays of photovoltaic cells, not seen), which generate electricity by harnessing the energy in sunlight.
