Definitions

  • This invention relates to a solar energy conversion system.
  • the invention relates to solar energy conversion to electrical power and will therefore be described in this context.
  • the solar energy conversion system may be used to convert solar energy to other forms of energy.
  • Most solar energy conversion systems include a parabolic reflector for the reflection for sunlight.
  • the parabolic reflector comprises a curved surface that reflects all incident solar radiation, which is parallel to a principal axis of the reflector, to a single focal point. This concentrates the solar radiation for conversion to electrical power.
  • a photovoltaic cell is located at the focal point to convert the concentrated solar radiation to electrical power.
  • a tracking mechanism is used to move the reflector in accordance with the relative movement of the earth to the sun so that all incident solar radiation remains parallel to a principal axis of the reflector. This ensures that that the photovoltaic cell is always at the focal point to maximize energy conversion during daylight hours.
  • parabolic reflector is must be moved about at least two axes to keep the photovoltaic cell at the focal point of the reflector.
  • the movement of the reflector is therefore, relatively complex.
  • the tracking mechanism is difficult and costly to produce.
  • the cost of producing parabolic reflectors is relative expensive due to the need to for specialized machinery.
  • a series of parabolic reflectors are required to cover large areas.
  • the invention resides in a solar energy conversion system comprising:
  • a solar radiation reflector having a plurality of elongate reflective members that are fixed in position relative to each other, said solar radiation reflector being mounted for rotation about a single axis;
  • a rotation device operatively connected to said radiation reflector for rotating said radiation reflector about said single axis
  • At least one solar radiation transducer located at a position coincident with at least one focal area of the plurality of angled reflective members of said solar radiation reflector;
  • a solar tracking unit for tracking the relative movement of the sun relative to the earth; said solar tracking unit causing said rotation device to rotate said solar radiation device toward the sun;
  • the solar radiation reflector is secured to a base having a pair of upward extending mounting members.
  • the axis of rotation is in one plane only.
  • the plurality of angled reflective members is preferably arranged so that at least one edge of each angled reflective member is in a common plane.
  • Each of the elongate reflective members may have a reflective surface that is planar or curved.
  • the solar energy conversion system comprises two solar radiation transducers.
  • the angled reflective members preferably reflect incident solar radiation to at least two areas of focus coincident with said solar radiation transducers.
  • the solar radiation transducers maybe mounted on to respective said upward mounting members.
  • a longitudinal axis of the solar radiation reflector may be substantially parallel with the mounted solar radiation transducers.
  • the rotation device preferably includes a rotatable shaft supported by the base for rotation about said axis.
  • the rotation device also includes a drive mechanisms for providing motive force to rotate said solar radiation reflector.
  • the drive mechanism may be a d.c. motor.
  • the solar tracking unit preferably includes two solar radiation converters mounted on a pair of the angled reflective members that have opposing orientations.
  • the solar radiation converters may be electrically connected to a decision circuit.
  • the solar radiation converters provide an input for determining the amount of incident radiation upon each of the angled reflective members at any point in time.
  • the decision circuit may comprise voltage comparators for comparing the voltage potentials of the two solar radiation converters.
  • the decision circuit preferably causes said drive mechanism to rotate the reflector when the measured voltage potentials of the two solar radiation converters are not balanced thereby indicating uneven solar radiation being received at the respective solar radiation converters.
  • the solar radiation converters are two small photovoltaic cells which are matched or linearised so that their voltage outputs are equal for the same amount of incident light.
  • FIG. 1 is an illustrative embodiment of the solar energy conversion system in accordance with invention.
  • FIG. 2 is a schematic of the solar tracking unit of the solar energy conversion system.
  • FIG. 3 is a schematic of a decision circuit of the solar tracking unit of FIG. 2.
  • FIGS. 4 and 5 are illustrative embodiments of the operation of the solar energy conversion system.
  • FIG. 1 shows a solar energy conversion system 10 including a base 20 to which is secured a plurality of mounting members 30 and a solar radiation reflector 40 .
  • the solar radiation reflector 40 comprises a number of planar reflective members 41 and 42 that are joined to each other. Each planar reflective member 41 is joined to an adjacent planar reflective member 42 along an edge. This forms a radiation reflector 40 having a corrugated shape as shown. A process of extrusion, using either plastics or metallic or glass or any other suitable material, is used to produce the corrugated shape of the solar radiation reflector 40 .
  • the reflective members 41 and 42 each have different inclinations. Hence, when each reflective member is provided with the same direction of incident solar radiation, the reflected solar radiation is reflected at a different angle from each of the reflective members 41 and 42 .
  • the mounting members 30 are used to mount solar radiation transducers 31 and 32 .
  • the transducers 41 and 42 are mounted to the mounting members 30 such that when incident solar radiation hits the reflective members, 41 or 42 , the reflected solar radiation is concentrated at either transducer 31 or 32 . That is, a focal area of the plurality of reflective members 41 or 42 is coincident with the respective transducers 31 or 32 .
  • angles for the reflective members 41 and 42 depend on the position of the solar radiation transducers 1 and 32 . Various angles may be chosen for the reflective members 41 and 42 and these may be determined depending on where the solar radiation transducers 31 and 32 are mounted on mounting members 30 . A person skilled in the art would not have any difficulty in experimenting with numerous angles to achieve the most optimum and desired result. Furthermore, the planar surface of each of the angled reflective members 41 or 42 provides a simpler construction than the parabolic concentrators used in prior art systems.
  • a rotation device 60 is operatively connected to the base 20 for rotating the solar radiation reflector 40 about a single axis X.
  • the rotation device 6 includes a rotatable shaft (not shown) attached to the base 20 and extends longitudinally with respect to the solar radiation reflector 40 thereby providing rotation of the solar radiation reflector and solar radiation transducer 41 and 42 about the axis X.
  • the rotation device 60 is operated by a drive mechanism (not shown) having a dc motor 150 as shown in FIG. 3.
  • FIGS. 2 and 3 there is shown a solar tracking unit 70 and the decision circuit 100 which together provide the necessary electrical input for causing the rotation of the reflector 40 .
  • the solar tracking unit 70 comprises two solar radiation converters 8 and 9 mounted on the reflector 40 .
  • the two converters 80 and 90 are electrically connected to the decision circuit 100 .
  • the radiation converters 80 and 90 are small photovoltaic cells that have been matched or linearised so that their voltage outputs are equal for the same amount of incident solar radiation. This is achieved by straight manufacturing or the outputs may be tuned or conditioned and amplified by electronic or physical means such as masking or doping.
  • the photovoltaic cells 80 and 90 are located on a central pair of angled reflective members 41 and 42 that forms an isosceles triangle with the base 20 .
  • the photovoltaic cells 80 and 90 are mounted the pair of angled reflective members that have opposing orientations. Therefore the photovoltaic cells 80 and 90 enable to determine the amount of incident radiation upon each of the angled reflective members of radiation reflector 40 at any point in time.
  • the decision circuit 100 is comprised of comparators 110 and 120 , and relays 130 and 140 that control the operation of the dc motor 150 that is used to rotate the reflector.
  • the angle of the incident radiation 160 on the photovoltaic cells 80 and 90 are equal and therefore the area and amount of solar radiation collected will be the same.
  • the voltage outputs for the photovoltaic cells 80 and 90 are therefore the same and hence, comparators 110 and 120 are inactive and no power is supplied to the dc motor 150 .
  • FIG. 4 illustrates the situation where the earth rotates and the incident solar radiation 160 on photovoltaic cells 80 and 90 are no longer equal. Consequently, the area and amount of solar radiation will be greater on photovoltaic cell 80 than on photovoltaic cell 90 . Hence, the output voltage on photovoltaic cell 8 will be greater than photovoltaic cell 90 . This will cause comparator 110 in FIG. 3 to activate relay 130 which will then activate the dc motor 150 and provide an anti clockwise motion until equilibrium is achieved as shown in FIG. 2.
  • FIG. 5 illustrates the situation before sunrise or after cloud cover where the angles of the incident solar radiation 160 are different on photovoltaic cell 80 and photovoltaic cell 90 .
  • the amount and area of incident radiation collected on photovoltaic cell 90 will be greater than on photovoltaic cell 80 , and therefore the output voltage on cell 90 will be greater than cell 80 . Consequently, this will cause comparator 120 to activate relay 140 and cause dc motor 150 to operate in a clockwise direction until equilibrium is achieved as shown in FIG. 2.
  • incident solar radiation 160 is reflected off the angled reflective members 41 toward transducers 31 whilst incident solar radiation 160 is reflected off the angled reflective members 42 toward transducers 32 .
  • the direction of the incident solar radiation relative to the reflective members 41 and 42 is maintained at a constant direction using the solar tracking unit. Therefore, the solar radiation reflector 40 provides the optimum amount of reflected solar radiation to the respective transducers 31 and 32 .
  • An advantage of the present invention is it only requires rotation of the reflector 40 in one axis to track incident solar radiation whist providing the optimum amount of reflected solar radiation. Further, the reflector 40 can be produced cost effectively and simply.
  • the solar radiation transducers may include photovoltaic cells for generating electricity connected to a power grid or alternatively they could house other means for energy conversion.
