Described laterally zygomorphic a pair of photovoltaic panel 31,32, be coupled respectively to two input ends of the second differential amplifier circuit, this the second differential amplifier circuit Single-end output is given described the second reducing motor 5, and this second reducing motor 5 drives described pedestal 1 to rotate to the place side of a higher photovoltaic panel of output voltage in described laterally zygomorphic a pair of photovoltaic panel; Principle of Process is same as the driving of the first reducing motor 4 for pedestal, repeats no more.
Above-mentioned luminous energy tracker is in when work, and by symmetrical, and a pair of photovoltaic panel 21,22 at an angle to each other, to the illumination of single direction, typical case gathers as sunshine; Due to direction of illumination and this angle difference to two photovoltaic panel 21,22 in photovoltaic panel obvious, thereby in two photovoltaic panel, produce the obvious output voltage of difference; Higher towards the voltage producing in the higher photovoltaic panel of light source degree; Therefore, make pedestal 1 turn to the place side of the photovoltaic panel that voltage is higher by described the first reducing motor 4, can dwindle the output voltage difference of this two of left and right photovoltaic panel 21,22 to photovoltaic panel, until the symmetrical plane of two of left and right photovoltaic panel 21,22 is parallel to direction of illumination; For upper and lower symmetry, and a pair of photovoltaic panel 31,32 at an angle to each other, also based on aforementioned principles, by the second reducing motor 5, pedestal 1 is rotated, finally make the symmetrical plane of upper and lower two photovoltaic panel 31,32 be parallel to direction of illumination; So far, this luminous energy tracker has been realized light source tracking location; Because the daylighting of photovoltaic panel is with respect to sensors such as photoelectric tubes, there is continuous and roomy daylighting area, therefore, labile factor is less, and the precision of sensing direction of illumination will obviously improve; In addition, because its structure is very simple, the core electronics of employing is only differential amplifier circuit, is therefore difficult to damage, and cost is lower.
Embodiment bis-:
Figure 4 shows that the side direction structural representation of the embodiment bis-of this luminous energy tracker; Be with the difference of embodiment mono-: on described pedestal 1, be also provided with the 3rd reducing motor 6, described the 3rd reducing motor 6, by a rotating shaft that is orthogonal to the driving shaft of first, second reducing motor simultaneously, connects two pairs of described photovoltaic panel simultaneously; The output terminal of two pairs of described photovoltaic panel is coupled respectively by the input end of commutator structure and described first, second differential amplifier circuit; Described commutator structure is often turning over after 180 ° any photovoltaic panel, from an input end of the differential amplifier circuit corresponding with it then be coupled to another one input end.
The outstanding advantages of this embodiment bis-is as follows: taking described symmetrical a pair of photovoltaic panel 21,22 as example, even if consider that profile is in full accord, the photovoltaic panel of distribution full symmetric, due to the otherness of manufacturing process and degree of aging, cause, under equal illumination condition, also likely having output voltage difference; Therefore, after making this to photovoltaic panel continuous rotation, two photovoltaic panel 21,22 are by continuous reversing of position, be that left photovoltaic panel becomes right photovoltaic panel, right photovoltaic panel becomes left photovoltaic panel, and continuous circulation, by described commutator structure, can make photovoltaic panel in left side all the time with one of described the first differential amplifier circuit fixing input end coupling, and photovoltaic panel in right side all the time with another fixing input end coupling of the first differential amplifier circuit; Due in left side or the photovoltaic panel on right side be no longer fixed as same photovoltaic panel, therefore, the difference of two photovoltaic panel in left and right will be cancelled.For laterally zygomorphic a pair of photovoltaic panel 31,32 and for the output characteristics of described the second differential amplifier circuit, consistent with described symmetrical photovoltaic panel 21,22, repeat no more.
Special needs to be pointed out is, described symmetrical photovoltaic panel is under the driving of described the 3rd reducing motor when half-twist, symmetrical photovoltaic panel is sayed from position, to become laterally zygomorphic photovoltaic panel, now, as tracker is not being realized alignment light source aspect upper-lower position, the output voltage of described symmetrical photovoltaic panel will play pendulum, but still there is tendentiousness feature, towards the more photovoltaic panel of light source, there is larger output voltage, because described laterally zygomorphic photovoltaic panel is also in the process of real-time adjustment position, therefore, the motion of comprehensive several directions, finally cause axis (the a-a line in Fig. 4) line of described light energy collecting parts to move closer to direction of illumination in the mode around circle, final completely parallel with direction of illumination.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
