Abstract: Systems and methods for dual tilt, ballasted photovoltaic module racking are provided herein. Under one aspect, a system for supporting first and second photovoltaic modules can include first and second elongated stiffeners respectively configured to be coupled to and support the first and second photovoltaic modules. The system also can include first and second feet respectively configured to be coupled to first and second grooves respectively provided within first and second ballasts. The system also can include a first stiffener hinge rotatably coupling the first and second stiffeners to one another, a first foot hinge rotatably coupling the first foot to the first stiffener, and a second foot hinge rotatably coupling the second foot to the second stiffener. At least one of the first stiffener hinge and the first and second foot hinges can include a respective mechanical stop inhibiting rotation of that hinge beyond a respective predetermined angle.

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.
