Abstract:
A method for installing a solar collector can include slip-forming a concrete track including a groove; curing the concrete track; placing a foot of a support structure of a solar collector in the groove; and applying adhesive between the foot and groove. Curing the concrete track optionally can include maintaining wetness of the concrete track for a sufficient period of time after slip-forming the concrete track. The foot optionally can include at least one of an aperture and a tab, and the adhesive flows through the aperture or around the tab. A foot of a support structure of a solar collector also is provided. The foot can be configured to be inserted into a groove and comprising a back wall, a first side wall including a first side tab, a second side wall including a second side tab, a third side wall, a fourth side wall, and a bottom wall.
Abstract:
A system for maintaining photovoltaic modules includes an elongated rail including first and second support surfaces and a first mounting surface disposed between the first and second support surfaces. An array of the photovoltaic modules is coupled to the first mounting surface and raised relative to the first and second support surfaces. A first vehicle can be disposed on the first and second support surfaces and can include a motor; a maintenance module selected from the group consisting of: a spray system configured to spray a product, and a remote inspection module; and first and second support legs suspending the maintenance module relative to the photovoltaic modules of the first array and being movably coupled to the first and second support surfaces so as to laterally and sequentially move the maintenance module in a direction parallel to the elongated rail responsive to actuation of the motor.
Abstract:
A method of locating a maintenance vehicle in a solar power field can include driving the maintenance vehicle on a track. A plurality of flags are coupled to the track at spaced locations. Each flag can include an ID tag and a contact target or a non-contact target. The maintenance vehicle can include an ID tag reader and a sensor configured to detect the contact target or the non-contact target. The method also can include driving the maintenance vehicle along the track to a position adjacent to a flag of the plurality of flags, reading by the ID tag reader the ID tag of that flag, and sensing by the sensor the contact target or the non-contact target. The method also can include, based on the reading and the sensing, identifying a unique location of the maintenance vehicle in the solar power field.

Abstract:
A system can include first and second stiffeners each coupled to a photovoltaic module, and first, second, third, and fourth legs. First and second joints rotatably couple the first and second legs to the first stiffener; and third and fourth joints rotatably couple the third and fourth legs to the second stiffener. A first crossbrace fixedly couples the first and second legs to one another; and a second crossbrace fixedly couples the third and fourth legs to one another. The first and second legs are rotatable about the first and second joints from a stowed position to an open position supporting the photovoltaic module, and the third and fourth legs are rotatable about the third and fourth joints from a stowed position to an open position supporting the photovoltaic module. At least one of the joints can include an electrical conductor coupled to the respective stiffener and leg.
Abstract:
An exemplary method for installing at an installation site a photovoltaic module including a panel and support legs includes disposing the photovoltaic module over a support surface such that the support legs are in a stowed position; lifting the photovoltaic module from a support surface while engaging a magnetic field with the support legs so as to maintain the support legs in the stowed position; disengaging the magnetic field from the support legs of the lifted photovoltaic module so as to release the support legs from the stowed position to an installation position in which the support legs are rotated downwards relative to the stowed position; and lowering the photovoltaic module to the installation site with the support legs in the installation position so as to install the photovoltaic module at the installation site, the support legs supporting the panel at the installation site.
Abstract:
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.
Abstract:
Under one aspect, a system is provided for rotating photovoltaic modules arranged in a row. The system can include an elongated structural member extending along and parallel to the row; protrusions coupled to the elongated structural member; an actuator; and drive mechanisms coupled to the photovoltaic modules. Actuation of the actuator can move the elongated structural member, the movement of the elongated structural member can move the protrusions, the movement of the protrusions can move the drive mechanisms, and the movement of the drive mechanisms can rotate the photovoltaic modules.
