Specifically, in the photovoltaic unit, the long side of the first photovoltaic module 11 is adjacent to the long side of the second photovoltaic module 12, or the narrow side of the first photovoltaic module 11 is adjacent to the narrow side of the second photovoltaic module 12. In order to reduce the obstruction of one photovoltaic module to another photovoltaic module, the long side of the first photovoltaic module 11 and the long side of the second photovoltaic module 12 may be selected to be adjacent.

The number of the photovoltaic units can be one, or more than two. If the number of the photovoltaic units is more than two, at least two photovoltaic units 1 can be selected to be sequentially distributed along the distribution direction of the first photovoltaic module 11 and the second photovoltaic module 12, and/or the distribution direction of at least two photovoltaic units 1 is perpendicular to the distribution direction of the first photovoltaic module 11 and the second photovoltaic module 12. It can be understood that there is a preset distance between two adjacent photovoltaic units 1.

The photovoltaic module can be obliquely fixed on the bracket 2, and of course, the photovoltaic module can be selected to be parallel to the bracket 2. In the practical application process, the inclination angle of the photovoltaic module is adjustable. If the photovoltaic module is obliquely arranged on the support 2, the photovoltaic module has a high end with a high height and a bottom end with a low height.

In the photovoltaic square array provided by the first embodiment, both the first photovoltaic module 11 and the second photovoltaic module 12 of the photovoltaic unit can be obliquely fixed on the support 2, the high end of the first photovoltaic module 11 is adjacent to the high end of the second photovoltaic module 12, and the high end of the first photovoltaic module 11 is higher than the high end of the second photovoltaic module 12, so that the first photovoltaic module 11 and the second photovoltaic module 12 are arranged back to back, the shielding of the shadow of the first photovoltaic module 11 on the second photovoltaic module 12 is effectively reduced, the distance between the first photovoltaic module 11 and the second photovoltaic module 12 is reduced on the basis of improving the power generation efficiency, and the water surface utilization rate is improved on the basis of improving the power generation efficiency; the unit area capacity of the photovoltaic floating power station is also improved, and the yield of an owner is improved.
