A solar energy collection system can include support devices made with bearings. Such bearings can include an inner partially toroidal surface for sliding contact and support of an outer surface of a torque tube. The toroidal surface can be made with a single radius of curvature or multiple radiuses of curvature and cylindrical portions. The bearings can include connectors for connecting the bearing members to a support housing. The connectors can be tool-less connectors.

A photovoltaic module mounting system is disclosed. The system includes a rail with an elongated body with opposing first and second shoulders and opposing first and second sides. A first track is defined by the first shoulder, a second track is defined by the first side, and a third track is defined by the second side. The first track has a first channel and a first slot, the second track has a second channel and a second slot, and the third track has a cavity. A connector bracket has a first flange, a second flange, and an elbow, the first flange forming a substantially right angle with the second flange, and the elbow being substantially L-shaped and extending at a substantially right angle from the second flange. In an operative configuration, the elbow of the connector bracket is engaged within the cavity of the rail.

A package integrated with a power source module may be provided. The package including a substrate having an upper surface and a lower surface, a chip on the upper surface of the substrate, a first power supply on the upper surface of the substrate, the first power supply at one side of the chip, an encapsulant encapsulating the chip and the first power supply, a second power supply on the encapsulant, the second power supply electrically connected with the substrate through a connection member, the connection member penetrating through the encapsulant may be provided.

A click-on clamping mechanism is for attaching, without tools, a clamp+tower subassembly to a slider bar (which is attached to a roof substrate with lag screws). The clamp+tower sub-assembly can have a height-adjustable, rail-less solar panel mounting assembly attached to it for mounting one or more photovoltaic solar panels thereto. The height of the solar panel mounting assembly can be easily adjusted, either before or after mounting of the solar panels. The click-on clamp+tower sub-assembly is easily removable from the slider bar. A click-on L-foot mount for attaching solar mount rails is also described. The click-on structures can be spring-loaded.

A building rooftop mounting structure including a sacrificial material that allows freedom of movement between itself and the rooftop as well as between itself and the mounting structure.

A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

A support structure for solar panels (100), comprising at least one solar panel (100) placed above a water basin and connected to a piston (1), which is fixed to the bottom at the water basin. The piston (1) is connected, on the side opposite to the bottom of the basin, to the solar panel (100) by means of a support bar or stem (10), which protrudes from the piston (1) and has first terminal elements (11) constrained to slide in respective side guides (20) of the solar panel (100). The solar panel (100) is hinged, at a lower edge (23), to a frame (9) which is integral with a hollow cylinder (3) installed about the piston (1) and slidably constrained to the piston (1) by second terminal elements (7) connected to the cylinder (3). The cylinder (3) consists of a float tank that can be filled or emptied at least partially with liquid or fluid means by pumping means (4) so that it can gradually move from a position of immersion, where the cylinder (3) is at least partially filled and rests on the bottom of the water basin, to a position of emersion, where the cylinder (3) is at least partially emptied and floats at a surface level (G) of the water basin.

Large scale exploitation of Solar energy is proposed by using floating devices which use solar energy to produce compressed hydrogen by electrolysis of deep sea water. Natural ocean currents are used to allow the devices to gather solar energy in the form of compressed hydrogen from over a large area with minimum energy transportation cost. The proposal uses a combination of well understood technologies, and a preliminary cost analysis shows that the hydrogen produced in this manner would satisfy the ultimate cost targets for hydrogen production and pave the way for carbon free energy economy.

A solar cell system and a flexible solar panel are disclosed herein. The solar cell system includes a glass housing, a set of rows of solar cells each defining a front side and a rear side and arranged within the glass housing. The solar cell system can also include a reflective element disposed in the glass housing and facing the rear side of the set of rows of solar cells and a first terminal coupled to a first end of the set of rows of solar cells, traversing through and sealed against the first end of the glass housing. The solar cell system can be configured with other solar cell systems into the flexible solar panel that is deployable in a wide range of potential applications.
