Description

SOLAR ENERGY POWER SOURCE
FIELD
Embodiments of the invention relate to methods and apparatus for generating energy from sunlight.
BACKGROUND
Solar energy power sources and associated methods for generating useful electrical or thermal energy from sunlight are known. In general, a solar energy power source comprises at least one surface, hereinafter a "collector surface", that is positioned to receive sunlight and "conversion apparatus" to convert the received sunlight to "useful" energy. Typically, the collector surface is a planar surface of the conversion apparatus or a surface of a component, such as a protective glass plate, of a structure comprising the conversion apparatus. The conversion apparatus may comprise any of a range of devices from relatively simple devices such as an optionally planar array of black painted plumbing pipes that carry water to be heated by exposure to sunlight, to state of the art photoelectric cell arrays that convert sunlight directly to electrical energy. For convenience of presentation, the collector surface and conversion apparatus are assumed to be components of a planar, solar panel.
Irrespective of the technical simplicity or sophistication of the conversion apparatus, for a given collector surface, hereinafter "aperture", over which sunlight is collected for conversion, more sunlight is collected for conversion to an extent that the collector aperture area is perpendicular to the direction along which sunlight is incident on the aperture. As a result, solar energy power sources generally comprise a solar tracking system that "follows the sun" and aims their respective collector apertures so that the aperture surfaces are substantially perpendicular to incident sunlight. (It is noted that when the aperture surface is substantially perpendicular to incident sunlight a normal to the surface points at the sun and is substantially parallel to a direction of the incident sunlight.) Typically, the solar tracking system rotates the collector apertures about a north-south axis to follow change in azimuth angle of the sun as it moves along an arc through the sky from sunrise to sunset during its diurnal cycle. Some solar tracking systems, "two-axis" tracking systems, also rotate the aperture about an east-west axis to follow seasonal changes, about 460, in elevation angle of the sun.
US Patent Publication 2009/0159075 describes a "single-axis" solar tracking system comprising a plurality of solar panels rotated about a north-south axis by a linear actuator to follow change in solar azimuth angle.
US Patent, 5,632,823 describes a two-axis solar tracking system comprising solar collector "securing assemblies", fixed to a shaft oriented north-south. A solar panel for collecting sunlight is mounted to each securing assembly so that it is rotatable about an "east-west" axis perpendicular to the north-south shaft. The solar panel is held at a given rotation angle about the east-west axis relative to the securing assembly by a stay connected to the panel and securing assembly. The north-south shaft is rotated to follow the change of azimuth angle of the sun and maintain the panels aimed at the sun during its diurnal cycle. The stay is adjustable to adjust orientation of the panel to compensate for seasonal change in elevation angle of the sun.
SUMMARY
An aspect of some embodiments of the invention relates to providing a relatively simple and inexpensive two-axis solar energy power source.
An aspect of some embodiments of the invention relates to providing a solar energy power source comprising a plurality of solar panels that are coupled to a same, relatively simple, azimuth drive for controlling an azimuth angle of the panels, and a same, relatively simple elevation drive that controls an elevation angle of the panels.
The azimuth and elevation angles of a panel are respectively the azimuth and elevation angles of a normal to the panel. When the normal to the panel points at the sun, the azimuth and elevation angles of the normal are substantially the same as the azimuth and elevation angles respectively of the sun. The azimuth and elevation drives are controlled to aim the panels so that they are substantially perpendicular to sunlight incident on the panels (i.e. their respective normals are substantially parallel to the direction of incidence of the sunlight).
In an embodiment of the invention, the azimuth drive comprises a substantially north-south oriented shaft, hereinafter an "azimuth beam", rotatable about its axis to which the panels are mounted so that they rotate with the beam. The azimuth beam is rotated to control the azimuth angle of the panels so that the panels track the solar azimuth angle and their respective normals point toward the sun as it moves across the sky during its diurnal cycle.
The elevation drive optionally comprises a "base rotation coupling" and a "slider" for each panel. The base rotation coupling attaches the solar panel to a fixed location along the azimuth beam so that the panel is rotatable about an axis perpendicular to the azimuth beam.
The slider is mounted to the azimuth beam so that it is relatively freely moveable along the azimuth beam. The panel is coupled to its slider by a support ann that is attached to the panel and to the slider by rotation joints that enable the support arm to rotate about axes perpendicular to the azimuth beam axis.
In an embodiment of the invention, the sliders are attached to a same "drive rod" that is translatable along the azimuth beam axis to control motion and position of the sliders along the azimuth beam. Optionally, the drive rod translates substantially parallel to the azimuth beam to control motion and position of the sliders. Optionally, the drive rod is translated by a worm drive. Optionally, the worm drive comprises a threaded pipe or rod screwed into a nut mounted to the drive rod or into a threaded internal surface of a lumen of the drive rod. In some embodiments of the invention, the worm drive comprises a pipe or rod having an internally threaded surface that is screwed onto an externally threaded surface of the drive rod.
Optionally, the drive rod is rigidly fixed to each slider. Motion of each slider controls an angle, hereinafter a "tilt angle", that the solar panel to which it is attached makes with the azimuth beam axis and thereby a corresponding elevation angle of the panels. In accordance with an embodiment of the invention, the drive rod is translated along the azimuth beam to tilt the panels so that they track seasonal changes in the elevation angle of the sun and maintain the solar panel normals pointing substantially to the sun throughout the year.
According to an aspect of some embodiments of the invention, first and second solar energy power sources are concatenated so that their respective azimuth beams and drive rods are driven by same apparatus.
In an embodiment of the invention, at least one extension slidable along the azimuth beam of the first solar energy power source is connected to the drive rod of the power source.
The at least one extension of the first solar energy power source is connected optionally to a slider of the second solar energy power source to concatenate the power sources. Optionally, the slider of the second power source has an extension to which the extension of the first solar energy power source is connected to concatenate the power sources.
There is therefore provided in accordance with an embodiment of the invention a solar energy power source comprising: a beam rotatable about its axis; a plurality of solar panels for receiving sunlight; a rotation coupling for each solar panel that connects the solar panel to the beam at a fixed location along the beam so that the panel is rotatable about an axis perpendicular to the beam axis; for each solar panel, a slider mounted to the beam so that it is moveable along the beam; a support arm rotatable about an axis perpendicular to the beam that connects the slider to its solar panel; and a drive rod translatable along the beam connected to each slider; wherein translation of the drive rod along the beam changes a tilt angle that each panel makes with the beam axis. Optionally, rotation of the beam about its axis rotates the drive rod about the beam axis. Additionally or alternatively, the beam optionally has a square cross section. In some embodiments of the invention, the beam has a rectangular cross section.
In some embodiments of the invention, the beam is mounted to a ring bearing leaving a space between the beam and the ring bearing.
In some embodiments of the invention, the solar energy source comprises a drive rod extension coupled to the drive rod and configured for coupling the drive rod to a drive rod of a similar solar energy power source so that the drive rods translate together.
In some embodiments of the invention, the solar energy source comprises a beam extension substantially collinear with and coupled to the beam, and configured to connect the beam to a beam of a similar solar power energy source so that the beams rotate together.
Optionally the solar energy power source comprises a drive rod extension coupled to the drive rod that passes through beam and/or the beam extension, the drive rod extension configured for coupling the drive rod to a drive rod of another solar energy power source so that the drive rods translate together.
In some embodiments of the invention, the solar energy source comprises a drive rod extension coupled to the drive rod that passes through the space and is configured for coupling the drive rod to a drive rod of another solar energy power source so that the drive rods translate together.
There is further provided in accordance with an embodiment of the invention, a solar energy power source comprising: a beam rotatable about its axis; a solar panel for receiving sunlight; a rotation coupling for the solar panel that connects the solar panel to the beam at a fixed location along the beam so that the panel is rotatable about an axis perpendicular to the beam axis; a slider mounted to the beam so that it is moveable along the beam; a support arm rotatable about an axis perpendicular to the beam that connects the slider to the solar panel; and a drive rod translatable along the beam connected to the slider; wherein translation of the drive rod along the beam changes a tilt angle that the panel makes with the beam axis.

DETAILED DESCRIPTION
Fig. 1 schematically shows a solar energy power source 20, in accordance with an embodiment of the invention.
Power source 20 comprises an azimuth beam 22 oriented substantially along a north-south direction to which a plurality of solar panels 24 are mounted in accordance with an embodiment of the invention. Whereas, solar energy power source 20 is shown comprising two solar panels 24, a solar energy power source in accordance with an embodiment of the invention may comprise more or less than two solar panels mounted to an azimuth beam.
Optionally, azimuth beam 22 has a rectangular or square cross section and is mounted to two support columns 25 and 26 so that the azimuth beam is rotatable clockwise and counterclockwise about the beam axis. Optionally, azimuth beam 22 is mounted to the support columns by ring bearings 30 that are press fit or bonded to the shaft and to matching sockets 31 formed in the support columns 25 and 26. Any of various methods known in the art, such as bonding, press fitting, or welding, and associated devices, may be used to secure ring bearings to azimuth beam 22. Similarly, any of various similar methods known in the art, may be used to mount bearings 30 to support columns 25 and 26. Optionally, azimuth beam 22 is fitted with a pulley wheel 35 for coupling azimuth beam 22 to a suitable motor or manual crank (not shown) operable to control rotation of the beam.
Each solar panel 24 is mounted at a different fixed location along azimuth beam 22 by a "base rotation coupling 32" optionally comprising a shaft 33 that passes through azimuth beam 22 and two support ears 34, optionally located at opposite corners of the solar panel. Shaft 33 and ears 34 are configured so that solar panel 24 is rotatable about an axis of the shaft. In the perspective of Fig. 1 only one ear 34 and a portion of shaft 33 protruding through the ear is shown for each solar panel 24.
Whereas base rotation coupling 32 allows solar panel 24 to rotate about the axis of shaft 33, the base coupling does not allow the panel to rotate relative to azimuth beam 22 about the azimuth beam axis. The solar panels are therefore constrained to rotate with the azimuth beam, and the beam is rotated, to track the sun's azimuth angle as it moves east to west during the day and maintain normals to solar panels 24 pointed substantially at the sun during the diurnal cycle. Normals to solar panels 24 are schematically indicated by block arrows 36. Assuming that support column 25 is at the north end of azimuth beam 22 the azimuth beam is rotated clockwise, as observed from the north end of azimuth beam 22, to follow the sun during the day.
Each solar panel 24 is also optionally coupled to a slider 40, that is movable relatively freely along azimuth beam 22, by a support arm 42. Optionally, the slider is configured as a "collar" that surrounds and rides on azimuth beam 22. Support arm 42 is attached to solar panel 24 and slider 40 by rotation joints 44 that enable the support arm to rotate freely about axes perpendicular to azimuth beam 22 at locations at which the support arm is attached to the solar panel and the slider. Optionally, as shown in Fig. 1, each rotation joint 44 comprises a mounting ear 45 and a rotation pin 46 which fits into a matching hole in support arm 42.
Each slider 40 is optionally rigidly attached to a drive rod 50 that is translated parallel to azimuth beam 22 by a worm drive 52 comprising a threaded rod 53 mounted to support column 25 and screwed into a nut 54 mounted optionally in a drive rod lumen at an end 55 of the drive rod. Threaded rod 53 is mounted to a support panel 57 fixed to azimuth beam 22 so that the threaded rod can be rotated about its axis, but does not substantially move parallel to the axis. The threaded rod is rotated to translate drive rod 50 to or away from support column 25. Assuming that threaded rod 53 is threaded with a right hand thread, clockwise rotation pulls drive rod 50 towards support column 25 and counterclockwise rotation of the threaded rod pushes the drive rod away from the support column.
Translation of drive rod 50 towards support column 25 moves sliders 40 towards the column and decreases a tilt angle "a" of the panels relative to azimuth beam 22. Translation of drive rod 50 away from support column 25 moves sliders 40 away from the column and increases tilt angle "a" of the panels relative to azimuth beam 22. In accordance with an embodiment of the invention, motion of drive rod 50 is controlled to adjust tilt angle a for seasonal changes in the sun's elevation angle so that the elevation of normals 36 is substantially the same as that of the sun and as a result, the normals are relatively accurately pointed at the sun. Optionally, threaded rod 53 is fitted with a pulley wheel (not shown) or coupling the threaded rod to a motor or manual crank (not shown) for controlling rotation of the threaded rod. By way of example, in Fig. 1 threaded rod 53 is manually rotated by rotating a lever 58. Optionally, the lever comprises a ratchet (not shown) for facilitating rotation of the threaded rod.
In an embodiment of the invention, solar energy power sources comprise a concatenation coupler 60 that enables first and second power sources to be coupled so that a same drive operates both azimuth beams of the power sources, and a same drive drives both drive beams of the power sources. Optionally, concatenation coupler comprises a slider 61, optionally similar to slider 40, connected to at least one "concatenation" extension 62 that is slideable along azimuth beam 22. By way of example, in Fig. 1 slider 61 is connected to two concatenation extensions 62. Each of the extensions passes through a space 63 between azimuth beam 22 and ring bearing 30. Assuming, as shown in Fig. 1 azimuth beam 22 has a square cross section, spaces 63 naturally exist when azimuth beam, 22 is fitted to the ring bearing 30.
Fig. 2 schematically shows solar energy power source 20 being concatenated with a similar solar energy power source 120. Solar energy power source 120 comprises an azimuth beam 122, a drive rod 150 and concatenation extensions 162 optionally similar respectively to azimuth beam 22 and concatenation extensions 62. The azimuth beams and concatenation extensions are aligned and attached to concatenate the power sources. Attaching may be done by any of various methods known in the art, such as by using adapters that adapt the azimuth beams one to the other, and/or adapters that match the concatenation extensions. Optionally, the concatenations extensions and/or azimuth beams are welded. Once the azimuth beams and concatenation extensions are attached, in accordance with an embodiment of the invention, a same drive is used to rotate azimuth beams 22 and 122, and a same drive is used to translate drive rods 50 and 150.
In the description and claims of the application, each of the words "comprise" "include" and "have", and forms thereof, are not necessarily limited to members in a list with which the The invention has been described using various detailed descriptions of embodiments thereof that are provided by way of example and are not intended to limit the scope of the invention. The described embodiments may comprise different features, not all of which are required in all embodiments of the invention. Some embodiments of the invention utilize only some of the features or possible combinations of the features. Variations of embodiments of the invention that are described and embodiments of the invention comprising different combinations of features noted in the described embodiments will occur to persons with skill in the art. For example, whereas the azimuth beam is indicated as being rotated by a motor or manual crank coupled to the azimuth beam using a pulley belt, the azimuth beam can of course be rotated by a motor or manual crank coupled to the beam with a gear train. And the cross section of azimuth beam 22 may be other than square or rectangular and may for example be circular or hexagonal. It is intended that the scope of the invention be limited only by the claims and that the claims be interpreted to include all such variations and combinations.
