Abstract: A solar absorber assembly (13) having upper and lower connectors (14, 15) between which tubes (16) extend for conveying water to be heated, the tubes (16) being surrounded by a glazing assembly (17) which is supported by the connectors (14, 15). The connectors (14, 15) may be connected with adjacent connectors (14, 15) of adjacent assemblies (13) to form a fence panel (11) which can be supported by posts (12), the fence panel (11) also serving as a security fence for swimming pools.

Abstract: A pair of horizontally elongated support structures is provided for supporting a horizontal panel member from opposite marginal edges thereof. The support structures each include an elongated horizontal member defining a central area for abutting, extending along and removable anchoring to one marginal edge of an associated panel member and upper and lower opposite marginal edges disposed above and below the central area thereof and the opposite marginal edges define a ridge extending along one marginal edge and a groove or trough extending along the other marginal edge. Accordingly, when the support structures are used in pairs of support structures with each pair supporting a horizontal door or other panel between the central areas thereof the ridges and troughs of vertically stacked support structures may be engaged with each other in order to support the panel members in horizontal, vertically spaced and stacked relation.

Abstract: A solar hot-water system having an absorber formed of plastic ducting adapted to be arranged unobtrusively on a roof surface whereby the water is heated by means of direct radiation from the sun and by means of conduction from the roof surface on which the ducting is supported.
