The Solar wall panel, a transpired solar collector, is mounted a few inches from the building’s outer wall. The precision perforations in the wall panels allow outside air to travel through the face of the panel. Solar heated air at the surface of the panel is drawn through the perforations where it rises between the two walls and enters the building’s central ventilation system or supply fan. Pre-heated air supplied through this means less energy consumption for the heaters for the building. (Source: ATAS International, Inc./ InSpire Wall Solar Air Heating)
