Since there is no space occupied by the guide rail, the photovoltaic module can be more closely arranged, so that the same area of the roof can install more photovoltaic modules, thereby improving the power generation efficiency per unit area and the total installed capacity of the power station, which is beneficial to increase the power output and investment return.
