A mobile panel maintenance system including a mobile panel maintenance unit having a base supported for translational motion over a surface within a panel array and a carriage movably mounted to the base to position a panel maintenance assembly in relation to a panel surface for panel maintenance.

A laminated structure assembly includes, between an upper transparent substrate and a lower transparent substrate, different combinations of a photovoltaic layer, a light-adjusting layer and a light-emitting layer that are stacked in sequence from top to bottom, and bonding layers are provided to bond adjacent layers. There is also provided a window assembly that includes the laminated structure assembly and a controller electrically connected to the laminated structure assembly. There is also provided a method for adjusting a window assembly, a computer device for control and a computer-readable medium. The laminated structure assembly provides a combination of a plurality of functions, thereby meets requirements of users.

An A-Frame solar panel array system is configured to produce a high amount of electrical power for a given amount of ground space with a plurality of solar panels on both a forward beam and a plurality of solar panels on a trailing beam in an elevated position above the ground. This elevated positioning enables more solar panels to be configured over a given amount of ground area. The solar panels are spaced along the trailing and forward beams with a vertical offset between the trailing and forward beams to enable sunlight to pass therethrough to enable exposure to sunlight, through the forward beam array of solar panels onto the trailing beam array of solar panels. A solar panel actuator is configured to rotate the solar panels for increasing solar panel exposure throughout the year. The solar panels may only be configured to rotate trailing/forward.

A pest-control structure for a photovoltaic (PV) module installation may include a support beam mounted to a support surface. The support beam may include an interface surface. A PV module may be mounted to the support beam. At least one exclusion spacer may be mounted to the support beam at the interface surface or the PV module. The at least one exclusion spacer may restrict access to an area between the PV module and the support surface.

A vehicle sun shade is provided having a sun shade, at least one solar cell, and a heat source. The sun shade has a light receiving portion configured to be carried beneath a vehicle wind shield. The at least one solar cell is provided in the light receiving portion. The heat source is provided proximate the at least one solar cell traversing the light receiving portion configured to mitigate condensate occlusion of the at least one solar cell on a vehicle wind shield. A method is also provided.

Systems and methods for self-cleaning a surface of an object where an electrodynamic shield is mounted to a surface of the object. The electrodynamic shield includes one or more sets of electrodes atop a substrate, at least one or more sets of electrodes being covered in a protective film. A coating is applied to the top surface of the protection film. A signal pulse generator is connected to the one or more sets of electrodes. The signal pulse generator generates a pulse signal that causes the one or more sets of electrodes to generate an electric field. The pulse signal comprises a plurality of different pulse signals which have phase differences between consecutive signals, and the electric field causes a particle atop the coating to experience an electrostatic force and be repelled away from the coating. These pulse signals (including shapes, amplitudes, shifts, and frequencies) can be tuned to increase efficiency of removal depending on dust type and relative humidity.
