A sunlight reflecting assembly includes a box that has an entry and an exit. The exit is oriented at a substantially diagonal angle with the entry and the box is positionable outdoors such that sunlight passes through the entry. A first mirror is positioned within the box and the first mirror is comprised of a light reflecting material to reflect the sunlight that passes into the box. A second mirror is positioned within the box and the second mirror is comprised of a light reflecting material to reflect the sunlight that passes into the box. The second mirror is positioned on an opposite side of the box with respect to the first mirror. In this way the first mirror and the second mirror direct the sunlight that passes into the entry outwardly through the exit thereby facilitating the sunlight which passes through the exit to be directed toward a solar panel.

A system includes a containment vessel configured to receive and hold one or more pieces of personal protection equipment to be heated and decontaminated during a decontamination process. The system also includes a solar collection device configured to heat the containment vessel based on received solar energy. The solar collection device includes a body having a first portion and a second portion. The first portion includes a solar aperture configured to receive the solar energy. The second portion is configured to receive the containment vessel within the body of the solar collection device. The solar collection device also includes louvered slats across the solar aperture. The louvered slats are configured to be rotated in order to control an amount of solar energy passing through the solar aperture into the body of the solar collection device.

A solar energy harvesting assembly having a unique attachment that can be arranged, mounted, moved and attached to new or existing structures. Solar rings are mounted on any vertical structure that may benefit from solar power using an aesthetically pleasing design that is resistant to wind load. The assembly does not require the need for pitch, azimuth or bearing measurements. The assembly is also capable of energy harvesting from reflected light below with the use of bifacial photovoltaic panels. The mounting design allows the solar energy harvest device to be installed on any vertical structure, including light poles, power poles, parking structures and other minimal load bearing structures. Further, the assembly can be attached to water towers, existing radio towers (guyed, monopole, stealth, self-supporting towers) all used to create vast amounts of unshaded vertical space for solar energy harvesting.

A device is disclosed for the storage and transfer of solar thermal energy which includes a casing having a irradiation opening for the entry of incident solar radiation in a irradiation region of the casing. a bed of fluidizable solid particles received within the casing, and a plurality of reflecting and radiating surfaces arranged within the irradiation region and configured to convey the solar radiation entering through the irradiation opening, after multiple reflections, on the bed of particles.

A module clamp for coupling one or more solar panels to a racking system of a solar tracker. The module clamp includes a bolt and a clamp head.

A hydrogen production apparatus includes: a first furnace configured to heat a mixed gas of a raw material gas, which contains at least methane, and hydrogen to 1,000° C. or more and 2,000° C. or less; and a second furnace configured to accommodate a catalyst for accelerating a reaction of a first gas generated in the first furnace to a nanocarbon material, and to maintain the first gas at 500° C. or more and 1,200° C. or less.

An external concentrator is provided for use with heat collection elements (HCE's of a solar parabolic trough power plant. In one arrangement, the concentrator includes a plurality of ribs that are adapted to extend radially outward from the outside surface of an HCE and along the linear length of the HCE to help redirect stray/spilled light into the absorber tube of the HCE. In another arrangement, the concentrator includes a shield placed on or near a surface of the HCE opposite of the parabolic reflective trough. The reflective shield includes ribs or brims that are disposed adjacent to one or both lateral edges of a reflective shield applied to the outside surface of a HCE tube to increase the collection of stray light reflected by the reflective trough.

This invention relates to photovoltaic (PV) systems with solar trackers. Retractable auxiliary panels are positioned at opposite sides of a solar panel along its tilt direction. The auxiliary panels do not obstruct the direct solar irradiation onto the solar panels, but rather redirect additional solar irradiation to the solar panels, including both direct beam and diffuse sunlight. While solar panels tilt to track the sun, configurations of the auxiliary panels can be adjusted to avoid shading on adjacent solar panels. Compared to conventional PV systems on solar trackers, the proposed PV system can significantly improve overall sunlight collection and PV system output throughout a day.

A photovoltaic intensification system includes a solar array stand, further including a mounting base; a mounting column; a solar array frame, a solar array, solar array lenses or reflectors, a light sensor, an elevation actuator, and a horizontal actuator; and a solar system cart, further including: a cart enclosure, a radiant solar cooker chamber, cart reflectors, and cart wheels. Further included are a vertical tilt ring, a strong-arm rod, a mass pivot rod, an elevation actuating ring, a horizontal tilt ring, and mounting brackets. A power and control system for photovoltaic intensification further includes a battery charger, a battery, an A/C inverter, a solar control unit, a remote control, a thermo electric freezer component, and a heat exchanger. A solar control unit includes a light sensor control circuit and a temperature control circuit, or a processor, a non-transitory memory, an input/output, an actuator controller, and a temperature controller.

The present invention relates to a method for controlling land surface temperature using stratospheric airships and a reflector. In the method for controlling land surface temperature using stratospheric airships and a reflector, four corners are connected to a lower end of support lines coupled to be disposed vertically downward from a plurality of airships, and sunlight is reflected by a reflector unfolded into a tetragonal shape in the air, wherein the reflecting surface of the reflector plate is maintained at an angle to remain perpendicular to an incident angle of sunlight to shield, or redirect, the land surface from incident sunlight.
