Single-support system
The photovoltaic mounting system consists of only one support and a diagonally running strut and can be used worldwide. As with the other systems, the module type and arrangement can be freely selected. A characteristic feature of the system is the deliberate omission of further supports. The solution is particularly suitable for very hard and stony soils. Since pile-driving is not possible here without further ado, pre-drilling is required. This increases the costs. Although the supports in the single-support system have to be more massive due to the significantly higher bending moments, their number is limited, as are the costs for predrilling and ramming. The single-support system is therefore preferable to the other systems if the substrate is very difficult to pile.
