A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may also refer to large power generating installa
Water heating system deployed on a flat roof. The pipes that carry the heat away can be seen embedded in the absorber, a flat plate painted black. In this example the heat is stored in the tank above the panels.
