[Embodiment] Please refer to the first, second and third figures, which are preferred embodiments of the solar power judging device of the present invention, comprising: a body 1 〇, a plurality of photo sensors 20 and A computing module 3〇. The base body 10 is a three-dimensional base body, and the plurality of illumination surfaces are non-coplanar, and the base body 10 receives at least one illumination surface to receive the incident sunlight when the white light has solar rays. Since each illumination surface is not the same, the ten sides, that is, there is an angle conversion relationship between the adjacent illumination surfaces, wherein the angle conversion relationship includes at least an azimuth angle and a tilt angle relationship. The body 彳〇 <tan is not limited' can be a hemispherical seat, a hemispherical polyhedron, a ceremonial cone, a round cone, a stereoscopic ladder, and the like. The seat body 10 of the present embodiment is a “! τ sentence four-sided flat-topped cone” which includes a top surface (U for up) and four side wall surfaces (R ^ 201140005 for left, B for back 'F for front), Each of the side wall faces has the aforementioned angular conversion relationship with the top surface. Each of the high-beam sensors 20 is correspondingly and fixedly disposed on the surface of the illumination surface, and the mother-photo sensor 20 receives illumination from a solar source s, and generates an electrical signal output to the operation module 30, wherein The electrical signal is related to the intensity of a solar radiation generated by the solar source S, the solar radiation comprising up to the radiation PD and a dispersion > lighter shot psky. Wherein, the direct light pD is the solar radiation directly received by each photo sensor 20 from the incident direction of the solar light source s, so the direct radiation Ρ〇 and the incident angle relationship between each photo sensor 20 and the solar light source s Related to, and related to the state of the atmospheric environment (such as climate); after correcting the angular relationship of each photosensor 20, one of the vertical components of the direct light shot can be expressed as: & cos clip. The moon/light shot P sky is the light sensor 20 receiving the solar light source s after being reflected or scattered by the atmospheric environment or surrounding buildings, and has changed the original incident direction instead of scattering and diffusing solar radiation from all directions. Diffuse radiation

The Psky is relatively independent of the angle of incidence of each of the photosensors 20 and the solar source S. The operation module 30 reads and receives the electrical signal from each photosensor 20, and then uses the angle conversion relationship of each photosensor 20 and a solar orientation information 40' to estimate a transmittance through a conversion estimation method. a ratio of the maximum available optical power to the direct radiation and the diffuse radiation. The solar orientation information 4〇 is related to the geographic location (latitude and longitude) of the measurement point and a measurement time. Therefore, the operation module 30 detects the geographical position of the detection point and the S measurement time by external or self-test, as an estimation. The parameter of the maximum available optical power. The penetration rate is the ratio of the instantaneous measurement optical power to an optical power basis, and the maximum can be used as the 201140005 optical power for any of the optical sensors 20, the solar panel or the light energy detecting device is perpendicular to the sunlight. The solar output optical power sensed by the incident direction. The 3H computing module 3 is a single-chip circuit, a programmable logic circuit or the like, and has a circuit module with independent computing capability. The computing module 30 of the embodiment includes a central processing unit 31 and a central unit respectively. The processing unit 31 is electrically connected to an analog-to-digital converter 33, a solar position calculation unit, a display unit 37', and a plurality of amplifiers 35, wherein each amplifier 35 is electrically connected to the photo sensor 2, and is amplified. Connected light sensor

The electrical signal is output to the analog-to-digital converter 33, and the analog-to-digital converter 33 digitizes the electrical signal and outputs it to the central processing #元31. The solar position calculation unit 34 reads the time and latitude and longitude data of the solar position information 4 to calculate an instantaneous solar position and sends it to the central processing unit 31. The central processing unit 31 uses the conversion estimation method to calculate the maximum available optical power and the ratio of the direct radiation to the diffuse radiation according to the read instantaneous solar position and the digitized electrical signal. The solar orientation calculation unit 34 of the embodiment obtains time, latitude and longitude from an external clock chip and a latitude and longitude input unit (which can be manually input or read from a global satellite positioning device), and is stored therein. The 10,000-year calendar formula refers to the operation to get the instantaneous sun position. In the aspect of the conversion estimation method, since the positional relationship of each of the photosensors 2 〇 with respect to the solar light source S is different, the ratios of the direct radiation and the diffuse radiation of the solar light source S respectively sensed are different; In other words, some or some of the photosensors 20 that are perpendicular to the incident direction of the solar source S or have a vertical projection component can sense a relatively large proportion of direct radiation under normal weather conditions, while facing away Sensing of the solar sensor s photo sensor 2 8 8 201140005 The result may only contain diffuse light shots. Therefore, the light sensors 20 can obtain the solar light source according to the sensing result of the light output of the solar light source S and the angle conversion relationship of each light-sensing device by coordinate conversion, algebraic operation, and database break. In the sense of the environmental environment at the time, the maximum available optical power that can be received and obtained by the device 20 (the optical power when the light is sensed to be 20 in the vertical direct path of the solar light source). therefore:

When a light-receivable solar panel device adopts the embodiment, any light sensor 20 that is theoretically consistent with the solar panel arrangement of the solar panel device can also detect the light that the solar panel should receive.
