A solar collector whose absorber plate is made of a conventional building material, e.g., tile, stucco, concrete or the like, and forms the outer surface, e.g., wall or roof, of the building. The fluid to be heated, typically air, flows behind the absorber rather than between an absorbing plate and a cover of glass or other transparent material, and heat is transferred to the fluid by metal conductors which extend from adjacent the outside surface of the absorber to, and define at least part of the flow passage. The system includes a cold tank of liquid in which heat is stored at a relatively low temperature, a heat tank of liquid at a relatively higher temperature; and a heat pump for transferring heat from the cold tank to the heat tank. There is a cold exchanger in the cold tank for receiving heated fluid from the collector and transferring heat therefrom to the liquid in the cold tank, and a heat exchanger in the heat tank for the transferring heat from the liquid in the heat tank to the air used to heat the building interior.
