Problems solved by technology

[0007] However, the signal provided by this dot-matrix sun azimuth detector 2' is discontinuous, which makes the adjustment accuracy based on the output signal limited.
Moreover, when the sunlight incident position is located in the part between the central photosensitive element 11 and its peripheral photosensitive elements, the solar azimuth detector 2' has no output signal, and at this time the azimuth of the sun cannot be judged, so that the adjustment of the angle of the solar panel is insufficient precise

Embodiment Construction

[0029] The sun azimuth detector of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Fig. 3 shows a photodetection component 200a of a solar azimuth detector according to an embodiment of the present invention. The photodetection unit 200a includes two photodetection elements 201 and 202 carved on the photosensitive material of the same substrate. As shown in FIG. 4 , the substrate is rectangular, and the photodetection elements 201 and 202 are respectively two right-angled triangle parts with the same shape formed by dividing the diagonal of the rectangular area, and the inclination angle is θ. The electrical signals generated by the elements 201 and 202 are respectively I 1 and I 2 , I 1 and I 2 The value of is proportional to the area of ​​the element 201 or 202 exposed to sunlight.

[0031] The photodetection unit 200a is arranged inside a housing, which may be in the shape of a cuboid with a gap at the top, ...

Abstract

The invention discloses a sun azimuth detector including: the shell has the transmission gap on the top and the first photodetection parts. The first photodetection parts include the fist an second photodetection parts with the same shape and formed on the photosensitive material substrate, which can provide the electric signal by responding to the sunlight through the gap respectively. The output signal of the sun azimuth detector has the special numeric relation with the battery board azimuth, so it has improved the precision of battery board angle adjusting system to the battery board. Otherwise, by the invention, it can get the processing signal of the difference relative value which is less influence by the outer sunlight intensity, so it can improve the reliability if the solar battery board adjusting system.

Description

technical field [0001] The invention relates to a solar azimuth detector, in particular to a solar azimuth detector with a photoelectric detection component capable of outputting continuous signals in response to the sun azimuth. Background technique [0002] In various devices utilizing solar energy resources (for example, solar power generation equipment), photoelectric conversion solar panels are increasingly used. In order to improve the photoelectric conversion efficiency, in addition to improving the manufacturing process of silicon photovoltaic cells, another method is to adjust the angle of the solar panel. The following formula shows the illuminance E (ie, light energy) obtained by the photoelectric conversion solar panel surface: [0003] E=E 0 cosθ [0004] Among them, θ is the angle between the incident light and the normal of the illuminated surface, E 0 Indicates the illuminance obtained on the surface of the solar panel when θ is 0 (that is, the sunlight i...
