Sundial and solar panels. The photovoltaic cells (dark blue) are on the offices of the Aerni Fenster factory,Arisdorf,Switzerland. This building was among the first in Europe to have a hybrid BIPV (Building Integrated Photovoltaics) solar thermal system,dating from the 1990s. This captured the heat in sunlight as well as generating electricity. On the sundial WOZ (German: wahre ortszeit),local apparent time (apparent solar time),is shown by the shadow cast by the gnomen.
