A floating solar system having a peripheral buoyant pontoon within which is suspended an array of individual photovoltaic panels each equipped with a float. A stabilizing skirt drops down into the water underneath the pontoon and creates a more placid “moon pool” within the pontoon to reduce turbulence from wave action and therefore enhance the efficiency of the array of photovoltaic panels. A plurality of the floating solar systems may be aggregated to form an island of units. The individual panels or rows or columns thereof may be flat (horizontal) or tilted so that they can be oriented more normally with regard to the sun's rays.

A lightweight reflector with a load bearing structure based on a tensile spoke-wheel. The spoke structure is especially compatible with dish parabolic mirrors, but has utility as a carrier structure for any round functional surface, including flat or slightly-curved mirrors used in central tower solar systems, parabolic dishes for radio telescopes and antennas, and for non-concentrating thin film solar panels. There are no radial members loaded in compression. All the spokes pull the rim inwards, and the rim is compressed in the circumferential direction. The imbalance in spoke tension results from the application of load provides the rigidity of the rim in respect to the hub, both for in-plane and out-of-plane forces. Ribs stiffen the spokes to resist wind and gravity, but are not structurally supported by either the hub or the rim. Lightweight reflector tiles match the wheel structure and create the reflective surface.
