A solar tracker includes a sunlight-detecting unit, a control unit, a first motor and a second motor. The sunlight-detecting unit detects the position of the sun. Based on the position of the sun, the control unit instructs the first motor to rotate a solar cell array and the second motor to tilt the solar cell array.

A sun-locating apparatus includes a substrate, a mounting unit, a photo-detecting unit, an optical element and a cover. The mounting unit is provided on the substrate and formed with an upper aperture and a lower aperture in communication with the upper aperture. The photo-detecting unit is located in the lower aperture. The photo-detecting unit includes at least four photodiodes. The optical element is provided on the mounting unit for covering the upper aperture. The cover is provided on the substrate for covering the mounting unit, the photo-detecting unit and the optical element.
摘要:
A method is provided to track the sun. An omnidirectional sensor is used for acquiring sun's position. The sensor can track sun's position in an omnidirectional way. A controller is also provided to control the tracking. When the sun shines strongly, the sensor is controlled to track the sun's position. When the sun does not shine strongly, the tracking is stopped. Thus, the cost for tracking the sun's position is reduced and accuracy of the tracking is enhanced.

An adjustable device for supporting a sun-tracking unit includes a framework and first and second supporting elements. The framework includes lower and upper portions. The lower portion of the framework includes two transverse long tubes and a longitudinal long tube for interconnecting the transverse long tubes. The upper portion of the framework includes two vertical tubes each extending from a related one of the transverse long tubes, two transverse short tubes each extending from a related one of the vertical tubes, and a longitudinal short tube for interconnecting the transverse short tubes. The first supporting element is connected to the transverse short tubes. The second supporting element is adjustably connected to the first supporting element.

A solar tracker includes a sunlit-detecting unit, a control unit, a first motor and a second motor. The sunlit-detecting unit detects the position of the sun. Based on the position of the sun, the control unit instructs the first motor to rotate a solar cell array and the second motor to tilt the solar cell array.
