What are the photovoltaic support columns generally used for

The tracking photovoltaic support system utilizes a slender and elongated rotating main beam to support the entire PV array, which is connected to the ground through columns. The torsional stiffness of this structure primarily relies on the characteristics of the main beam, rather than the stiffness of the panels themselves [1] .

At present, the commonly used solar photovoltaic supports are mainly composed of concrete support, steel support and aluminum alloy support. Concrete support is mainly used in large-scale photovoltaic power stations, because of its self-weight, it can only be placed in the field, and the area with a good foundation, but with high stability, it .

Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.

The solar PV MMS is supported by a single column (single pole). In this case, as per the end condition that is one end fixed and the other end free end, then the effective length should be 2L and none of the solar structures are designed for that.

Photovoltaic mounting system can be divided into fixed, tilt-adjustable and auto-tracking three categories, and their connection methods generally have two forms of welding and assembly. The fixed bracket can be divided into roof type bracket, ground type bracket and water type bracket.
