Rotatable support systems for photovoltaic modules and methods thereof
Rotatable support system for mounting one or more photovoltaic modules and method thereof. The system includes a stiffener configured to be attached to the one or more photovoltaic modules, a column connected to the stiffener through at least a rotatable component, and a foot connected to the column. The column is configured to rotate from a folded position towards an unfolded position, and stop at the unfolded position separated from the folded position by an angle difference. The angle difference represents the maximum range of rotation for the column.
