DETAILED DESCRIPTION

[0037] Before any embodiment of the invention is explained in detail, it is to be understood that the present invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The present invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

[0038] The matters exemplified in this description are provided to assist in a comprehensive understanding of various exemplary embodiments disclosed with reference to the accompanying figures. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the exemplary embodiments described herein can be made without departing from the spirit and scope of the claimed invention. Descriptions of well-known functions and constructions are omitted for clarity and conciseness. Moreover, as used herein, the singular may be interpreted in the plural, and alternately, any term in the plural may be interpreted to be in the singular.

[0039] Referring now to the figures, FIG. 1 shows an exemplary front perspective view of the present invention. Components illustrated in FIG. 1 include: module frame 100; lift bar 200; solar module 300; left float 400; right float 500; float upper surface 700; primary frame 1000; front decking 1100; module frame brace 1200; deck grating 1300; solar cell 1400; and lift bar pivot 2400.

[0040] Note that sizing may vary greatly depending on configuration, use, specific solar panels selected, etc. Therefore, dimensions and sizes set forth herein reflect the sizing of a specific application of the invention, but in no way reflect a requirednor preferred sizing or configuration. For example, in accordance with some embodiments of the present invention, the complete unit may be approximately 9630816 (e.g. 2.4 meters7.80.4 meters). While this sizing can vary, this dimension may allow for the collapsed solar docks to be stacked on flatbed trailers approximately eight (8) high in two (2) rows, thereby potentially permitting approximately sixteen (16) 4 assembled units per truck.

[0041] The lift bar 200 may be a collapsible support arm. The lift bar 200 may be replaced by or used in conjunction with an a-frame support, hydraulic lift, air strut, cable, gears, chain and/or belt depending on the embodiment. In accordance with some embodiments (but in no way limiting) FSPV units may be eight (8) foot x twenty-four (24) foot sections (e.g. 2.5 meter7.5 meter); each fitted with approximately six (6) vendor furnished panels. In general, each floating section may be comprised of two (2) or three (3) floats and fitted with an aluminum cross deck arranged to support large solar panels. Each floating section may be fitted with a longitudinal work deck for personnel access capable of interconnecting with adjacent floating sections and be designed for stacking. The work decks may be integrated into the floating section or attached separately. In some instances, side work decks going in a perpendicular direction may be desirable. Some embodiments may use approximately eight (8)twenty-six (26) foot (e.g. 2 meter8 meter) floating solar sections depending on the application and permitted dimensions for transport.

[0042] In some embodiments, each solar panel module may be capable of being hinged/pivoted prior to deployment so as to position the panels at a preset or indexed angle of inclination. The inclination angle may be fixed upon set up and manually lifted in place or by means of shore side equipment. The storage profile of the panels may be generally such that the units are stackable without loading of the solar panels from the stack loads. The solar panels are enabled to be grouped into several hinged panels based on their aggregate weight. The design and arrangement of the floating modules may be configured to permit the fit up of a reflective panel below the solar panels so as to provide bifacial absorption. In general, all surfaces are considerate of maximizing bi-facial refraction.

[0043] Additionally, in some and other embodiments, the overall construction of the modules may be of aluminum profiles and welded sections (though other materials may be utilized). It may be desirable to use readably available hardware for maintenance, cost and ease of assembly. In addition to the transport and shipping loads, additional considerations are given towards the lifting of the modules, and environmental loading.

[0044] It may be generally intended that the solar arrays/fields are installed on closed bodies of water, generally not subject to vessel traffic or similar means of wake generation and that the sea conditions may be limited to a very light wind induced chop. Similarly, wind loads may include hurricane force winds up to a specified velocity, but enabling adjustment of the panels to the stowed position may protect against potential wind damage.

[0045] Again, while sizing may vary depending on application and configuration, in accordance with some embodiments of the present invention framing dimensions when using aluminum and similar materials range from approximately two (2)three (3) inches through two (2)five (5) inches (5 cm7.5-13 cm) and that U-channels are 11.25 and 1.53 (2.5-4 cm3-8 cm). The floats made of HDPE may be approximately 584 through 588 (e.g. 1.5 m2.5 m10-21 cm). In some cases, these dimensions may provide particular transportation, deployment and shipping benefits. However, actual dimensions may vary significantly from these ranges depending on the embodiment and requirements for the installation.

The decking grate may provide grip, drainage, and light transmission. In accordance with some embodiments of the invention, decking grate may provide 60% light transmission. In accordance with some embodiments of the present invention, decking may be solid and highly reflective and/or white. Greater light transmission in the decking may enables growth of sea grass, plants and other life that depend on solar light. It may also enables heating and evaporation of water underneath the decks.
