[Prior Art] With the rise of green energy, solar energy becomes a kind of energy that can be directly obtained and has its own environmental protection. However, solar panels that receive solar energy will directly affect solar energy conversion due to factors such as the material of the solar panel itself and the environment in which it is installed. The efficiency of electrical energy. How to improve the power conversion rate of solar panels becomes a problem that needs to be overcome, and the method of improvement is traditionally, in addition to the material properties of the solar panels themselves, another effective method is to rotate the solar panels in time so that the sunlight can be readily Normally incident on the solar panel to achieve the highest power conversion rate. However, the trajectory of the Earth's orbit around the Sun changes with time and season; in addition, sunlight is more likely to encounter refraction and/or scattering of dust, suspended particles and water molecules in the atmosphere as it traverses the Earth's atmosphere. The phenomenon that the solar panel cannot effectively absorb the solar energy, thereby causing the power conversion efficiency of the solar panel to decrease. In order to improve the above problems, a tracking system is generally used to track the actual illumination orientation of the sunlight, so that the solar panel can effectively obtain the maximum conversion efficiency in any setting environment. Among them, the chase system can be divided into active chasing system and passive chasing system. In general, the active tracking system will have a higher solar panel power conversion rate than the passive tracking system. However, the active active chasing system that has been developed still has 201113662 in the space that can be improved in power conversion efficiency. Therefore, the development of new methods and equipment for chasing the Japanese is an important issue for the newspaper. Set to mention

In addition, the sensing unit b surface and the sensing unit ^ The surface system respectively generates corresponding complex sensing signals Ζβ and /c.

依此類推，可如同第四圖所示，進一步導出其他方位 角角度範圍，其係分別為： θζ =^~\ic/iB) θζ Stan—1 (iD"c) + 9〇。 θζ =^(^/^) + 270° 其中，kL、匕與~係為立方體感應模組各側面B、匸、 Β 1、_E所產生之該等感測訊號，以及&係表示照射在各感 測單元表面的太陽光之方位角。 、二考第五〜七圖，係說明第一圖中正立方體感應模組用 以獲得仰角之示意圖。上述仰角係根據正立方體感應模組 之頂々面（A)之感測訊號與任兩個鄰近的正立方體感應模組 之該等側面(B、C、D與扮之該等感測訊號中獲得。於第 五圖中’正立謂感應模組1G具有複數制單雄、B、 C、D與E)，其係分別取感測單元A面_B面-C面、感測單 疋A面-C面-D面、感測單元A面〇面·£自、a面_^面七 面來計算仰角。參考第六圖，係太陽光照射在感測單元B 面與C面（於此定義在〇。〜90。）之方位角的範圍内，並於 201113662 感測單元A面獲得/sine之太陽光的垂直有效分量、於感 測單元B面獲得/cosacos<9z之太陽光的垂直有效分量、於 感測單元C面獲得/cosasin<9z之太陽光的垂直有效分量。 故對於感測單元B面與感測單元C面之兩面有效的分量組 合而言，其為/cosa(cos<9z +sin(9z)。此外，感測單元A面、 感測單元B面與感測單元C面係分別地產生對應的複數感 測訊號乙、匕與k，用以推導出以下的公式： iA /(iB + ic) = Is'ma/[/cosa(sinθζ + cosθζ)] or = tan-1 [(iA /(iB + ic)x (sin Qz + cos Θζ)] 亦或者可利用感測單元A面、感測單元B面與感測單 元C面所接收太陽光之有效面積來計算，同樣可獲得與上 述相同之公式。 依此類推，可以用同樣方式來推出在不同的方位角範 圍下的仰角公式，如同第七圖所示，其係分別為： a = tan"1 [(iA Ι{ιΒ + /c ) x (sin θζ + cos ΘΣ)] a - tan'1 [(/^ !{ic +/0)x(sin(^ -9〇e) + cos(^z -90°))] a = tan~l[(iA /(iD +/£)x(sin(^z -180〇) + cos(^-180°))] a = tan'1 [(/, l{iB + /£) x (sin(^2 - 270°) + cos(^2 - 270°))] 其中g、~與~係為正立方體感應模組所產生之 該等感測訊號、&係表示照射在各感測單元表面的太陽光 之方位角、以及《係表照射在各感測單元表面的太陽光之仰 角。 再者，由於立方體感應模組有良好的光遮蔽效應，故 可利用光行進的直線性特性，而達成精準的感應，亦即當 201113662And so on, as shown in the fourth figure, the other azimuth angle ranges are further derived, which are: θζ =^~\ic/iB) θζ Stan-1 (iD"c) + 9〇. Ζζ =^(^/^) + 270° where kL, 匕 and ~ are the sensing signals generated by the sides B, 匸, Β 1, _E of the cube sensing module, and & The azimuth of the sunlight on the surface of each sensing unit. The fifth to seventh pictures of the second test are used to illustrate the schematic diagram of the positive cube sensing module used in the first figure to obtain the elevation angle. The elevation angle is based on the sensing signal of the top surface (A) of the positive cube sensing module and the sides of any two adjacent positive cube sensing modules (B, C, D and the sensing signals) In the fifth figure, the Orthodox sensing module 1G has a complex system of single males, B, C, D and E, which respectively take the sensing unit A surface _B surface - C surface, sensing unit The A-C-D-D surface, the sensing unit A surface, the surface, and the a-surface _^ surface are used to calculate the elevation angle. Referring to the sixth figure, the sunlight is irradiated in the azimuth of the B surface and the C surface of the sensing unit (herein defined in 〇.~90.), and the sunlight of /sine is obtained on the surface of the sensing unit A at 201113662. The vertical effective component, the vertical effective component of the sunlight of /cosacos<9z is obtained on the surface of the sensing unit B, and the vertical effective component of the sunlight of /cosasin<9z is obtained on the surface of the sensing unit C. Therefore, for a combination of components effective on both sides of the sensing unit B surface and the sensing unit C surface, it is /cosa (cos < 9z + sin (9z). In addition, the sensing unit A surface, the sensing unit B surface and The sensing unit C surface respectively generates corresponding complex sensing signals B, 匕 and k to derive the following formula: iA /(iB + ic) = Is'ma/[/cosa(sinθζ + cosθζ)] Or = tan-1 [(iA /(iB + ic)x (sin Qz + cos Θζ)]) It is also possible to use the sensing unit A surface, the sensing unit B surface and the sensing unit C surface to receive the sunlight effectively. For the area calculation, the same formula as above can be obtained. By analogy, the elevation formulas under different azimuth ranges can be derived in the same way, as shown in the seventh figure, which are: a = tan" 1 [(iA Ι{ιΒ + /c ) x (sin θζ + cos ΘΣ)] a - tan'1 [(/^ !{ic +/0)x(sin(^ -9〇e) + cos(^ z -90°))] a = tan~l[(iA /(iD +/£)x(sin(^z -180〇) + cos(^-180°))] a = tan'1 [(/ , l{iB + /£) x (sin(^2 - 270°) + cos(^2 - 270°))] where g, ~, and ~ are the sensing signals generated by the positive cube sensing module &amp The system indicates the azimuth of the sunlight that illuminates the surface of each sensing unit, and the elevation angle of the sunlight that illuminates the surface of each sensing unit. Furthermore, since the cube sensing module has a good light shielding effect, The linear characteristics of light travel can be utilized to achieve precise sensing, that is, when 201113662
