A foldable solar panel assembly is configured to support solar panels in a compact and folded, undeployed position, and in an unfolded, deployed position, and to fold and unfold between its deployed and undeployed position.

A frame enhancer may include a body, a first extension extending from the body and including a first notch, a second extension extending from the body, and a third extension extending from the body and including a second notch. The first extension and the second extension may define a first slot. The second extension and the third extension define a second slot. The first slot may be configured to receive a first side of a support arm, and the second slot may be configured to receive a second side of the support arm. The first notch may be configured to lock the first side of the support arm in the first slot, and the second notch may be configured to lock the second side of the support arm in the second slot. At least a portion of the first and third extensions may be configured to support a flange.

A system composed of a photovoltaic module, itself composed of a multilayer housed in a frame and of at least one anti-vibration device that is able to be fixed with respect to the multilayer and in which the photovoltaic module as a whole has a total mass, a modal mass, and a natural frequency of vibration; the at least one anti-vibration device has: a mass, a natural frequency equal to a natural frequency of vibration of said photovoltaic module considered on its own, to within 15%, and a level of damping of the anti-vibration device considered on its own, equal to at least twice the level of damping of said photovoltaic module considered on its own.

A solar canopy has a solar panel assembly including a first solar panel coupled to a second solar panel and oriented non-parallel with respect to the second solar panel. The solar panel assembly has an effective solar-panel-assembly wind loading less than a sum of a first-solar-panel effective wind loading and a second-solar-panel effective wind loading determined individually. An actual load applied by the solar panel assembly to a solar-panel-assembly support structure coupled thereto when the solar panel assembly is subject to a wind loading is less than a design load for the solar panel assembly subject to the wind loading based on a sum of a first-solar-panel net pressure and a second-solar-panel net pressure determined independently.

A solar generator apparatus includes: a generator module having first to fourth corner portions; a middle column mounted on a fixed structure and pivotally connected to the generator module; first and second winding devices attached to the middle column; first to fourth cables; and first to fourth elastic anchors. The first to fourth cables have first ends respectively connected to the first to fourth corner portions. The first and third cables are wound around the first winding device. The second and fourth cables are wound around the second winding device. The first to fourth elastic anchors are elastically mounted on the fixed structure. The first to fourth cables respectively pass through the first to fourth elastic anchors to form two W-shaped structures. Each elastic anchor includes an elastic member and a restricting member connected in parallel. The restricting member restricts a maximum deformation amount of the elastic member.

A folded down support (12) allows for stronger solar panels (10) and the support replaces most of the solar racking required for solar installation which further reduces the cost of the photovoltaic solar system. The solar panels (10) can be arranged so that solar panels form a solar collector solar panel array. The solar panel (10) can be set on a surface by itself or with ballast (43). It can also be attached to the surface by fastening the solar panel to the side supports. If the solar panel frame and supports are electrically conductive, the design allows for self electrical grounding between these conductive parts when the side supports are pivoted to the down position. The folded up support allows for high density storage and shipping.

In an example, the system has a mechanical isolator comprising an elastic material configured to separate the panel rail from the torque tube cause destructive interference with a natural resonant frequency of the system without the mechanical isolator to reduce a mechanical vibration of the system.

Wind screen for one or more photovoltaic arrays and method thereof. For example, a wind screen for one or more photovoltaic arrays includes a screen foundation including a concrete block, and one or more perforation blocks on the concrete block. In another example, the wind screen is configured to cover at least a first side of each array of the one or more photovoltaic arrays.

Methods of operating solar tracking apparatuses are described. For example, a method includes determining a minimum amount of energy required to move the solar tracking apparatus from a first position to a second position. An available radiance is estimated for a solar resource coupled to the solar tracking apparatus. The solar tracking apparatus is moved from the first position to the second position prior to a point in time when the energy derivable from the available radiance is less than the minimum amount of energy required to move the solar tracking apparatus from the first position to the second position.
