A system for the collection and utilization of solar energy. A manifold is mounted on the roof of a building with a major portion of the manifold being contained within the building. A plurality of double-walled, glass solar energy collector tubes are inserted into that part of the manifold which extends above the roof of the building. A gas, such as air, completely fills the manifold and collector tubes. The gas is circulated from the manifold to the ends of the collector tubes from whence it returns, having been heated during the movement. A heat exchanger mounted in the manifold has a working fluid, such as water, passing through it. The heated gas impinges on the heat exchanger, giving up much of its energy to the fluid passing through the heat exchanger. The working fluid is then used for space heating or cooling functions within the building.
