The base 1 is installed on the wooden pier 7, and the wooden pier 7 and the base 1 are installed in a detachable manner. Two wooden pier 7 are arranged under each base 1 to support the base 1. There is a certain gap between the two wooden pier 7. The distance between wooden piers 7 can be changed flexibly to realize the test of photovoltaic modules of different sizes. In addition to the above-mentioned embodiments, the base 1 may not be supported by the wooden pier 7, but may be realized by using other supporting devices or directly enlarging the size of the base 1 . Referring to Fig. 3, the edge of the photovoltaic module 3 includes an upper surface 31, a lower surface 32 opposite to the upper surface 31, and a side surface 33 connecting the upper surface 31 and the lower surface 32. When clamping, the upper surface 31 is pressed The lower surface 21 of the pressing plate 2 is pressed against the base 1 .

Please refer to Figures 2, 3, and 4, the base 1 includes a top plate 11 that clamps the edge of the photovoltaic module 3 together with the pressure plate 2, a bottom plate 13 opposite to the top plate 11, and a bottom plate 13 that is perpendicular to the top plate 11 and connects the top plate 11 and the bottom plate 13.
