Therefore, the technology of using solar energy instead of other energy sources is also Constantly launched. The use of solar energy in today's life is very widespread. Solar panels are usually fixedly installed outdoors, and changing climate or other environmental factors often shorten the life of solar panels, such as long-term rain or night dew. Damage to solar panels and internal parts shortens their product life. Or a situation such as dust, moisture, shaking, or vibration may cause the solar panel to malfunction. However, because when using solar energy to generate electricity, it is often used to convert more solar energy, so when a small number of solars occur (four), (four) S has to detect each solar panel conversion effect = remove the replacement of new solar panels or carry out Maintenance, in order to maintain the conversion performance of the slit recording system. 201234616 99005TW1 36519twf.doc/n [Invention] The present invention provides a solar panel conversion efficiency detecting device and a detecting method thereof, which can detect solar energy with low conversion efficiency The present invention provides a solar panel conversion performance detecting device, comprising a plurality of solar panels, at least one junction box, and a host, wherein the plurality of panels of the tera-month b are mutually connected by a plurality of wires.

The coupling sensing unit and the data base calculate a conversion threshold according to the conversion performance information of each solar panel, and determine whether there is a low conversion effect solar panel according to the conversion performance threshold value, and determine that there is a low conversion. The solar panel of the performance emits a warning signal. In an embodiment of the invention, the junction box comprises a plurality of series connectors, a first output connector, a second output connector and a network connector: The plurality of solar panels are connected in series through the plurality of series connectors. The junction box is coupled to the DC power distribution box through the first output connector and the second output connector, or connected in series or in parallel with another junction box. Conversion Effect of the Multiple Solar Panels of the Invention The present invention further provides a solar panel conversion performance measuring apparatus comprising a plurality of solar panels, a secret box, a plurality of waterproof connection nodes, and a host. Each towel has its own money-proof connection. The network is connected to the adjacent it section by the network. The waterproof connection node and the solar panel are connected by wires and solar panels. Each of the two waterproof joints is waterproof joint node.

The main _ reduction box, and the conversion performance of the panel according to the energy panel determine whether there is a domain=number of low conversion performance and issue a 201234616 99005TW1 36519 twf.doc/n when determining the solar panel with low conversion performance. In one embodiment, the above-mentioned junction box includes a network connector's sensing unit that transmits the conversion performance of the solar panel to the host through the network connector. In an embodiment of the present invention, the host computer separately counts the number of times that the conversion performance of each solar panel is lower than the conversion performance threshold value within a predetermined time period to obtain a statistical value, and the statistical value is higher than a preset number of times. The solar panel is judged to be a solar panel with low conversion efficiency. In one embodiment of the invention, the host is configured to set a conversion performance threshold based on the conversion performance of each solar panel at a plurality of points in time. The invention further provides a solar panel conversion performance detecting method, which comprises the following steps: detecting the conversion performance of the solar panel; determining whether the conversion performance of the solar panel is lower than a conversion performance threshold; and calculating the conversion performance of the solar panel at a preset The time is lower than the conversion performance threshold to obtain a statistical value; whether the statistical value is higher than a preset number of times; and when the statistical value is a high preset number, the solar panel is determined to be a low conversion performance solar panel, and is issued A warning signal. In an embodiment of the invention, the solar panel conversion performance detecting method further includes setting the conversion performance threshold according to the conversion performance of the solar panel at a plurality of time points. Based on the above, the present invention utilizes the sensing unit in the junction box to detect the conversion performance of each solar panel, and determines the solar panel with low conversion efficiency according to the conversion performance of each solar panel through the host. The above described features and advantages of the present invention will become more apparent from the description of the appended claims. 201234616 99005TW1 36519twf.doc/n Embodiments FIG. 1 is a schematic diagram of a solar panel conversion efficiency detecting device according to an embodiment of the present invention. Referring to FIG. 1, the solar panel conversion performance detecting apparatus 100 includes a plurality of solar panels 102, a junction box 104, a host 106, and a database 108', and a junction unit 110 includes a sensing unit 110. A plurality of solar panels 102 are connected to each other by a plurality of wires (not shown) to form an array of solar panels. The junction box 104 is used to collect the wires, and the sensing unit 11 in the junction box 104 is used to detect the conversion performance of each solar panel 102. The method for detecting the conversion performance of each solar panel 1 〇 2 can be, for example, detecting the magnitude of the voltage or current signal generated by converting the solar energy of each solar panel 1 〇 2 to represent the difference in conversion performance between the solar panels 1 〇 2 . . The host 106 determines whether there is a solar panel with too low conversion efficiency according to the conversion performance of each solar panel 102. For example, if the sensing unit 110 detects the conversion performance of each solar panel 102 every five minutes, the host unit 〇6 can detect the respective solar panels 1〇2 according to the sensing unit 110 at multiple time points. The conversion performance calculates a conversion performance threshold value and compares the conversion performance of each solar panel 1〇2 with the conversion performance threshold to find the solar panel 102 whose conversion performance is lower than the conversion performance threshold. Since the conversion efficiency of the solar panel is relatively sensitive to changes in the surrounding environment, it is not possible to determine that the solar panel 102 whose conversion performance is lower than the conversion performance threshold is a solar panel having a low conversion efficiency with only one sampling result. The host 106 can count the conversion performance of each solar panel 102 at different time points within a preset time (for example, within one hour), and convert the performance of each solar panel 102 at the time of each sampling 201234616 99005TW1 36519twf.doc/n. The calculated conversion performance thresholds are compared, and the number of times each solar panel 102 is below the conversion performance threshold for a preset time is counted to obtain a statistical value. If the statistical value is higher than a preset number of times (for example, 12 times), the host 1〇6 determines that the solar panel 102 is a solar panel with low conversion efficiency, and sends a warning signal to inform the user to enable the user to convert Inefficient solar panels are repaired. For example, 'green' in Figure 2 is a plot of conversion performance versus sampling time for a solar panel. It can be seen from FIG. 2 that the conversion performance of each solar panel 102 is substantially equal for most of the time, but in the portion of the elliptical region eight, the conversion efficiency of the partial solar panel 102 is low, and the host 1〇6 can be judged in the elliptical region A. Whether the sampling points are specific solar panels 1〇2, if the same solar panel is lower than the sampling value of the conversion performance threshold (that is, the statistical value is higher than the preset number (12 times)), the solar panel can be determined Conversion performance is too low. The conversion performance information of each of the solar panels 102 at different time points (for example, the conversion performance of each solar panel 1 () 2 and the number of times each solar panel 102 is lower than the conversion performance threshold) may be stored and recorded in the database 108, For the host to perform phase_calculation and judgment comparison. It is worth 2 that the sampling interval of the above sensing unit 11〇, the host 106 is the preset time for the conversion performance material to be lower than the invalid energy threshold, and the solar panel effect is judged ====:: Limit the use of two consecutive situations § and the above parameters to achieve the most accurate judgment. 201234616 99005TW1 36519twf.doc/n In addition, the manner in which the host 106 calculates the conversion performance threshold may also vary depending on the actual application. For example, half of the average value of the conversion performance of each solar panel 102 at the same sampling time point can be calculated as the conversion performance threshold value, or the average value of the highest conversion performance and the lowest conversion performance of each solar panel 102 at the same sampling time point can be calculated as Convert performance thresholds.

When the number of solar panels 102 is too large, it may be increased. The number of the junction boxes 1〇4 is used to effectively integrate the wires connecting the respective solar panels 1〇2, and the plurality of junction boxes 104 may be (iv) or connected in parallel according to the actual situation. Further construction of the junction box 104 will be described later. . FIG. 3 is a flow chart showing a method for measuring the conversion efficiency of a solar panel according to an embodiment of the present invention. Please refer to 3, summarizing the above-mentioned method of solar panel conversion performance side device, and judging whether each solar panel is η, the method may include the following steps. First, _ solar energy change performance (step coffee). Then, determine the conversion effect of the solar panel: First, the performance threshold (step outline. Among them, the conversion = 22 according to the conversion efficiency of each solar panel at multiple time points of the conversion board = point for each solar surface too + Or the number of times the performance threshold is changed at the same sampling time point to get a statistical value (step S鄕), followed by: the average value of the solar conversion performance and the lowest conversion efficiency. The performance is lower than the turn within a preset time and then 201234616 99005TW1 36519twf.doc/n determines whether the statistical value is higher than a preset number of times (step S308). If the statistical value is higher than the preset number, the solar panel is determined to have low conversion efficiency. The solar panel' sends a warning signal to inform the user (step S31〇), so that the user can perform maintenance on the solar panel with low conversion efficiency. Conversely, if the statistical value is not higher than the preset number, then return Step S302 continues to detect the conversion performance of the solar panel. As described above, the conversion performance of each solar panel is detected by the sensing unit provided in the junction box, and the host is utilized. Compared with the conversion performance of each solar panel and the conversion performance threshold calculated according to the conversion performance of each solar panel, not only can the solar panel with low conversion efficiency be correctly judged to allow the user to target the solar energy with low conversion efficiency. The panel is repaired to maintain the optimal power generation status of the entire solar power generation system, and the sensing unit disposed in the junction box is also free from direct contact with the intense outdoor climate change to reduce the life.
