And, in the theft monitoring arrangement 81 of solar module, even if do not measure the time T1 from transmission first pulse signal to reception first reflected signal (the first more than judgement threshold value reflected signal), and the first reflected signal reflected by reflecting element 5d is counted, also according to count value when receiving described first reflected signal of signal intensity of more than judgement threshold value, the position (closest to the position of the solar module M of one end of ring circuit 2 in solar module M) of stolen solar module M can be judged.As an example, in the example when the theft of Fig. 9, the 4th the first reflected signal reaches the signal intensity of more than judgement threshold value, so theft module numbering P1 is 4.
About the second theft location determination portion 12 too, after sending the second pulse signal from the other end of ring circuit 2, the second reflected signal reflected by reflecting element is counted, according to count value when receiving the second reflected signal of the signal intensity larger than judgement threshold value, judge the position closest to the solar module M of the other end of ring circuit 2 in stolen solar module M.
Therefore, by the theft monitoring arrangement 81 of solar module, the first theft position table 13 or the second theft position table 14 can be omitted, theft monitoring arrangement main body 3 can be made to become simpler structure.In addition, by the theft monitoring arrangement 81 of solar module, all the time the first reflected signal is counted, can detect that solar module M is not stolen, can improve reliability thus energetically.
The present invention is not limited to above-mentioned embodiment, certainly can carry out various change without departing from the spirit and scope of the invention.
Such as, describe in the above-described embodiment and connect connecting portion 5 on solar module M, detect the stolen situation of solar module M, but according to the present invention, such as also can connect connecting portion 5 on each solar panel forming solar module M, detect the stolen of solar panel.
