摘要:
Solar panels and assembled arrays thereof include a collection of relatively compact, high-capacity power units. Optical components of each power unit include a front window or surface glazing, a primary mirror, secondary mirror and receiver assembly. Primary and secondary mirrors are defined by respective perimeters, at least a portion of which may be substantially coplanar and in contact with the front window. Some primary mirrors are configured with a perimeter of alternating full and truncated sections, and are curved to a base portion forming a pilot hole therein. Receiver assembly mechanical components include an alignment tube for mating with the primary mirror's pilot hole and for housing a photovoltaic solar cell. A base plate provided adjacent to the alignment tube serves to radiate heat emitted by the solar cell, and in some embodiments an additional heat sink provides further passive cooling. A tapered optical rod also provided within the receiver assembly directs received sunlight to the solar cell where electrical current is generated.

A solar energy collection system comprises a frame for mounting the system on a suitable substrate and a plurality of solar panels disposed adjacent to one another on the frame. A first set of the solar panels are movable relative to a second set of the solar panels, for tracking movement of the sun during the day. Solar panels of the first set are arranged in alternating fashion with solar panels of the second set. In some embodiments of the invention, the panels in the second set of solar panels are stationary. The second set of solar panels, in some embodiments, are disposed substantially flat, relative to the frame and the substrate on which the frame is mounted. In some embodiments, differing from those in which the second set of solar panels are stationary, the second set of solar panels may be arranged to be movable relative to the first set of solar panels.

摘要:
A system [500] for producing solar energy at a desired temperature and pressure range includes a primary energy source [501] that is used in a Clausius Rankine cycle, with the primary energy source connected to and proximate to a plurality of solar collectors [520]. More particularly, at least one steam storage tank [501] feeds the expansion step of the Clausius Rankine cycle. This enables the system [500] to reliably supply energy during times when the solar collectors receive little or no radiation. According to one aspect of the invention, the solar collectors [520] reside on an artificial island [510a, 510b, 510c], preferably sea-based, or offshore, so that the steam storage tank [501a, 501b, 501c] can be located well below sea level. This enables the use of compressive forces from the sea water to counteract the outwardly directed pressure caused by the steam contained in the steam storage tank [501a, 501b, 501c]. Moreover, this storage tank [501c] may have a dual-walled structure [501d, 501e], for insulation purposes, and may be operatively connected to a sea level condenser [501i] to produce sweet water. Still further, steam from the steam storage tank [501] can be used to drive one or more absorption chiller devices housed within an absorption chiller unit [530a] that is operatively connected to an air conditioning system [530b]. And these structures can be located on the roof of a building [530] so as to supply air conditioning to the building [530].
