<p>A pontoon structure (30) is described that may be floated on a body of coolant liquid (38), with others in array (20). The entire array may be aligned with the sun in an azimuth direction, and each pontoon may be rotated to align it with the sun elevation. A solar energy conversion target, typically a photovoltaic conversion device, may be mounted on a portion of the pontoon structure that remains below the coolant over a wide range of sun elevations. An asymmetric focus lens may be used to direct light entering the pontoon toward the conversion target. A lens to make solar conversion systems shadow-tolerant is also described that is useful with pontoons that shadow each other, improving target illumination uniformity in the presence of partial shadowing by directing light uniformly toward the target from each plurality of subregions.</p> |
