Abstract:
A solar cell array is provided having a lattice or matrix structure such that no two solar cell devices are connected purely in series or purely in parallel. Accordingly, if a single solar cell device fails, there is an alternate path by which the output power of all other solar cell devices may contribute to the total output power of the solar cell array. Also, the power output of the entire array is much less sensitive to a low voltage or current for a single solar cell device than in a conventional array where devices are connected in series and in parallel. Beneficially, current setting devices, such as resistors, are provided for better matching the voltages and currents within the array, although in some applications, the resistors can be eliminated, or set to zero. The lattice or matrix structures may be extended in one, two, and three-dimensional patterns.
Abstract:
A tilted single-axis tracking system (20) for collecting solar energy includes a structure (22) for supporting an array (26) of photovoltaic (PV) modules (24) above a surface (28). The structure (22) includes a frame (34) having first and second legs (40, 42) configured to extend upwardly from the surface (28) and join at an apex (54). A base tensioning member (44) of the frame (34) is interposed between the first and second legs (40, 42). A torque tube (36) is pivotally retained by the frame (34) at the apex (54) and is configured for attachment of the array (26) of PV modules (24). A foot member (38) pivotally retains a tube end (60) of the torque tube (36) and is configured to rest on the surface (22). A first tensioning member (106) is coupled between the foot member (38) and the first leg (40), and a second tensioning member (108) is coupled between the foot member (38) and the second leg (42). A pre-tensioning member (110) extends from the apex (54) of the frame (34) and is configured for attachment to the surface (28). In an alternative embodiment, the pre-tensioning member (110) is omitted and pre-tensioning members (152) extend from each of the first and second legs (40, 42) and the foot member (38) and are configured for attachment to the surface (28).

Abstract:
The present invention provides a removably securable blind or awning having solar modules for converting solar energy into another energy form. The awning has an electrolyzer and fuel cells, or a reformer and fuel cells, for additional storage of that surplus energy produced by the solar modules for which the customarily provided storage elements lack sufficient storage capacity. Hydrogen and oxygen tanks, electrolyzers, reformers, and fuel cells can be disposed by appropriate measures in the available space in and/or on the frame body of the awnings such that space outside of the awnings for such items need only be found on an exception basis. The storage and release from storage of energy is regulated by a bus system. Water from one of a number of different sources can be conducted to the electrolyzer via guide drains mounted on the awnings and/or via other assemblies.
Abstract:
A tracking type photovoltaic power generator includes a clock for clocking a time and a sun direction sensor for outputting a signal indicative of a sun direction, a controller which calculates a first time when the sun the sun arrives at a culmination azimuth on the basis of the time clocked by the clock, detects a culmination azimuth on the basis of a difference between a second time when the culmination azimuth is detected and the first time. Accordingly, the generator automatically corrects the error of the time clocked by the clock.
