How to follow the tracks of? It is the key of problem place.The tradition tracking all is to adopt initiatively solar tracking tracking, and this tracking is compared with the system that does not follow the tracks of, and has played great role, but still comes with some shortcomings.I.e. initiatively solar tracking tracking control, majority are to set a low limit value, and is excessive when the sunlight angle deviating, when magnitude of voltage is low to moderate limit value, through control circuit, starts tracking motor and go to seek new light source direction.In case trace into new light source direction, tracking loop will be out of service.After will waiting sunlight to depart from certain angle under the normal condition, when voltage was low to moderate limit value once more, tracking motor starts once more sought new light source direction.This mode is a kind of tracking mode of initiatively seeking, and it can only be when tracing into the new light sources direction, keeps an angle of 90 degrees irradiation position with sunlight, and passing in time, the deviation of this lighting angle can be increasing.Improve if lower bound is followed the tracks of the trigger voltage value, that frequent the rotation will occur and follow the tracks of.For utilization on natural energy resources, receiving weather influence is frequent thing.Like cloudy weather, the frequent discrepancy of sunlight meeting cloud layer has just gone out cloud layer sometimes and has got into cloud layer again, because lower bound is followed the tracks of the raising of trigger voltage value, the floating voltage magnitude diminishes, and tracking in time and frequently.Cloudy weather changes, and tracker does not have recognition function, will be with come in and go out cloud layer and ceaselessly following the tracks of of the sun.The illusion that this Changes in weather causes not only makes the tracker motor frequently rotate power consumption, and the stability of solar photovoltaic generation system work is had certain influence.
Also have a kind of time control tracking now, it controls the photovoltaic battery panel rotational angle according to the clock rotary principle.This time control tracking mode has been broken away from the influence of Changes in weather, no matter cloudy, cloudy or night, only otherwise with the tracker dump, it can rotate by the clock rotary principle in 24 hours.Stop operating if cut off the electricity supply night, will proofread clock every morning so, otherwise the deviation of tracking time is followed the tracks of angle and just can't be guaranteed.
Be shown in the present solar energy sampling tracking means and the deficiency of existence, this case provides a kind of solar panel sampling tracking sensing device, and it does not receive the influence of Changes in weather, only the luminous energy of effective illuminating power generating is followed the tracks of.It adopts the polylith solar panel; Revolve round the sun and rotation track principle around the sun according to the earth; Maintenance of layout on ground, the semicircle sensitive surface of the elevation angle 125 degree is accepted the mode of light source irradiation with a kind of passive type; Utilize the photovoltaic property of solar panel self to accomplish opto-electronic conversion, realize the sensing device that effective illumination luminous energy sampling is followed the tracks of.Press the script rule of nature, farthest utilize effective luminous energy, reach round-the-clock purpose from the motion tracking solar energy.
