Abstract: A solar heating system comprising a collector panel with a plurality of beverage cans or the like received in holes drilled therethrough. The surfaces of the panel and the cans protruding from the front of the panel are painted with a dark, heat-absorbing paint and the circular tops of the cans, which are exposed through the other side of the panel, are left uncoated to radiate heat directly into a heat storage medium, such as a pile of rocks on the other side. A heating duct exits from the top of the heat storage chamber to the area to be heated and the return duct enters at the same level. Circulation of air through the heating duct is mechanically induced.
