System and method for mounting one or more photovoltaic modules includes one or more flexible rods, including a first end and a second end opposite the first end, each of the one or more flexible rods further including an inner core and a first jacket surrounding the inner core between the first end and the second end. The first end is configured to be attached to at least one photovoltaic module using one or more first adhesive materials. The second end is configured to be inserted into at least one hole of a modular rail and attached to at least the modular rail using one or more second adhesive materials. The one or more flexible rods are configured to allow at least a lateral movement in a first direction between the photovoltaic module and the modular rail and support at least the photovoltaic module in a second direction.

A system includes an elongated rail including support surfaces and a mounting surface disposed between the support surfaces. Photovoltaic modules can be coupled to the mounting surface and raised relative to the support surfaces. A first maintenance vehicle can include a cleaning head, actuator, motor, and support legs. The support legs can suspend the cleaning head over the photovoltaic modules and can be respectively movably coupled to the support surfaces so as to laterally and sequentially move the cleaning head parallel to the elongated rail and across each of the photovoltaic modules responsive to actuation of the motor. At least a portion of the cleaning head can be vertically movable between a disengaged position spaced apart from the photovoltaic modules and an engaged position in contact with at least one of the photovoltaic modules responsive to actuation of the actuator.

The present invention relates to a blade folding apparatus that may incorporate an overhead blade lifting system that reduces binding loads on blade pins induced by blade weight and pitch, and a folding mechanism that removes the necessity of personnel with external guide-poles to rotate main rotor blades. The apparatus may include flap locks, an overhead lifting system support structure attached to the flap locks, and two blade support beams to create and support a lifting point near each blades longitudinal and lateral center of gravity. The blade support beams may be fitted with an articulation mechanism that lifts and/or lowers the overhead lifting structure. The apparatus facilitates rapid folding of the main rotor blades, and, when used with blade clamping mechanisms, is capable of aiding in the removal and/or the re-installation of the main rotor blades without external lifting mechanisms.

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.
