An apparatus for mounting a power electronic device to a photovoltaic (PV) module. In one embodiment, the apparatus comprises a mounting bracket that mechanically couples the power electronic device to the backsheet of the PV module such that positioning of the power electronic device can be dynamically interchanged between a retracted position in which the power electronic device is pressed flat to the backsheet, and an extended position in which the power electronic device is coupled to the backsheet with an air gap between the power electronic device and the backsheet.

An earth mount utility-scale solar photovoltaic array with modules on the ground. The site can have support regions with an elevation between −20 cm and 40 cm of the ground. Implementations may include elevations between −10 cm and 30 cm of the ground surface; more than one row of modules; connectors joining adjacent modules; modules flexibly joined in one or two dimensions; connectors joining 2-4 modules; connectors electrically bonding some modules to adjacent modules; contact points controlling a direction of a ray normal to a plane of the modules; a dc output, and a DC:AC output voltage ratio is 1.02, 1.9, 1.21.8, or 1.31.7. These or other implementations may configure the module arrangement such that the arrangement can withstanding wind speeds greater than 150 mph without containing stowing or extreme dampening functionality. Implementations of the described techniques may include solar arrays and related methods.

A portable post office contained within an intermodal container is disclosed. Such a structure may include a rack movably secured to a track mounted in the ceiling of said container via a trolley. The rack may be configured to hold a plurality of post office boxes, each box having a lockable door facing the center aisle of the container, and an open end facing the rear of the rack. The rack may be positioned against an interior side wall of the container and secured in place via a locking mechanism to prevent access to the open ends of the post office boxes. An individual may release the locking mechanism and move the rack into the center aisle along the track to access the open ends of the post office boxes. The rack member may then be moved back along the track and re-secured against the side wall.

Trailer mounted portable solar power supplies disclosed can include lights and a backup generator. A solar array with solar panels can be connected to a 360 degree rotatable turntable mounted on a trailer frame enabling the capture of sunlight from all directions. A rotatable telescoping mast with mounted lights can be mounted to the trailer frame. Solar power supply systems can be configured with or without batteries. The AC voltage output can provide electricity for vehicles, homes, buildings, electric vehicles, etc. Portable solar power systems can implement multiple solar arrays to capture more sunlight and generate more electricity. The solar arrays and solar panels are foldable allowing the power system to be retracted for transport. The solar panels can also include sensors to control the positioning of the panels and turn the lights on and off by an onboard computer or wirelessly.

A solar cell power conversion device is disposed between a solar cell and a consumer premises distribution system. A storage battery power conversion device is disposed between a storage battery and the consumer premises distribution system. When an AC effective voltage in the consumer premises distribution system deviates from a voltage range defined in accordance with dead zone information transmitted from HEMS, system voltage stabilization control for returning the AC effective voltage to fall within the voltage range is performed by control of active power and reactive power that are output from a first DC/AC conversion circuit and a second DC/AC conversion circuit.

Photoelectric window blinds, which consist of a plurality of elongated lamellas, which are arranged in parallel and connected between each other by at least two stripes, equipped with a drive for their assembling, disassembling and changing an inclination angle, on which solar panels are mounted, the panels being connected between each other and equipped with a means for transmission of an obtained electric energy to external networks or to a means for storage. According to the invention, each solar panel is formed by at least two sections of solar elements, which are arranged on a base made of an electrically insulating material and covered by a temperature and moisture stable layer, coupled to each other and by a means for electrical connection embedded therein, and it is configured to receive at least one additional section. An edge section of each solar panel is equipped with a means for transformation of an output power, the means being a DC/DC transformer or a Schotky diode embedded into the base made of the electrically insulating material from a side of the panel faced towards the lamella, and coupled to a shared bus that is connected to a DC-to-AC current transformer. Therewith, a cross-section profile of the lamellas has a C-shape with curved edges, which form guides for mounting the solar panels in a longitudinal direction, wherein a distance between edges of the sections of the solar elements of the solar panel and edges of the electrically insulating base equals to a width of the edges of the lamella guides.
