A solar canopy has a solar panel assembly including a first solar panel coupled to a second solar panel and oriented non-parallel with respect to the second solar panel. The solar panel assembly has an effective solar-panel-assembly wind loading less than a sum of a first-solar-panel effective wind loading and a second-solar-panel effective wind loading determined individually. An actual load applied by the solar panel assembly to a solar-panel-assembly support structure coupled thereto when the solar panel assembly is subject to a wind loading is less than a design load for the solar panel assembly subject to the wind loading based on a sum of a first-solar-panel net pressure and a second-solar-panel net pressure determined independently.

A structural support block cooperates with a cone-shaped protrusion in a roof flashing. The support block and protrusion have a through-hole allowing a fastener to secure the support block and flashing to a roof. Cooperation of the support block and the cone-shaped protrusion in the roof flashing diverts water, particularly on sloped surfaces.

An absorber system solves problems of known absorber systems for use in solar fields in that the absorber tube is suspended on a rail below an absorber cover. The design also makes it possible to move measuring and cleaning robots and the like along the absorber tube more and allows the absorber tube and the secondary reflector to be jointly suspended, whereby an exact mutual alignment between the two components is enabled.

A photovoltaic apparatus includes: a power generation part; an angle changeable mechanism configured to support the power generation part so as to be able to change an elevation of the power generation part; a post configured to support the power generation part and the angle changeable mechanism; and a hinge mechanism configured to support the post so as to be able to change an angle of the post relative to an installation surface for the photovoltaic apparatus.

A parabolic trough collector module comprising an absorber tube, a parabolic reflector focusing the solar radiation to the absorber tube and with a reflector surface, and at least one support de-vice on which the parabolic reflector is mounted so that it can pivot. The support device includes a support head projecting over the reflector surface in the vertical direction, on which the absorber tube is mounted by a linear bearing structure forming a linear guide.

A solar heat exchanger in which the manifolds are connected together using a threadless connection arrangement in which the end of one manifold tube carries at least two annular seals and the internal bore of the end of the adjacent manifold tube is cammed and when locked, the connection of the two manifolds is resistant to loosening when exposed to repeated thermal expansion and contraction cycles.
