Abstract: A solar heating system for a structure in which a matrix of beverage containers of the convenient opening variety is mounted on a generally flat support member. The beverage containers extend through holes in the support member formed from alternating polygons of a generally checkerboard surface design. A resilient plug seals the opening at one end of each container and a pair of collector tubes extend through the plug into the interior of each container. The collector tubes of adjacent containers are connected together such that all containers are connected in a series relationship. Those surface areas of the support member not occupied by the containers are contoured and have an outer surface appropriate to reflect heat and light toward the containers which themselves have a coating of a heat and light conductive substance. Fluid is pumped from a reservoir and through the containers under sunny conditions or may be diverted from the matrix during cloudy conditions or at night.
