In practical application, in the same photovoltaic array supporting device, the number of the pile foundations in each row is generally the same, the pile foundations 1 in the corresponding position of each row are arranged in a row, and certainly, each row of pile foundations 1 and each row of pile foundations 1 can be in a mutually perpendicular relationship or form an included angle different from 90 degrees, in order to enable the inter-pile tie structure to achieve the best effect at the lowest cost, in one embodiment of the invention, the inter-pile tie structure is at least arranged between two pile foundations in the corresponding position of adjacent rows, namely, the inter-pile tie structure is arranged between the first pair, the second pair, … and the nth pair of pile foundations 1 in the adjacent rows, as shown in fig. 5, so that the distance between the pile foundations 1 in the corresponding position of the adjacent rows is the shortest, the size of the inter-pile tie structure is the smallest, mutual interference does not exist between the adjacent two inter-pile tie structures, and the installation is more convenient.
Of course, the inter-pile tie structure may be provided between the pile foundation 1 and the previous or next pile foundation 1 of the pile foundations 1 in the corresponding position of the adjacent row, so as to form an intersection of the inter-pile tie structures.
In the embodiment of the present invention, the photovoltaic array supporting device may include two, three or more rows of pile foundations 1, but considering that in order to enable the photovoltaic modules 3 to obtain more sufficient illumination, the photovoltaic modules 3 on the photovoltaic array supporting device need to be arranged in an inclined manner, generally, the height is north high and south low, which requires that the height of the pile foundations 1 needs to be sequentially increased from south to north, if the number of rows of pile foundations 1 included in the photovoltaic array supporting device is too large, the height of the north-most row of pile foundations 1 is too high, which is inconvenient for the installation and construction of the row of pile foundations 1, and the number of rows of photovoltaic modules 3 is too large, which is inconvenient for maintenance, for this reason, in the embodiment of the present invention, the photovoltaic array supporting device includes two rows of pile foundations 1, as shown in fig. 5 and 6.
