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 transparent solar heat absorbing apparatus includes a transparent member allowing sunlight to pass through, a wavelength selective member disposed beneath the transparent member, a heating tank formed between the transparent member and the wavelength selective member. The wavelength selective member allows light in a transmission range including at least a visible wavelength range to pass through and reflects light in a reflection range including at least an infrared wavelength range. At least one of the transparent member and the wavelength selective member has a waveform structure on at least one of its upper surface and bottom surface.

A solar thermal collector adapted to be assembled from a flat pack configuration, comprising a conduit (6) configured to carry fluid and to absorb radiation, a base (1) above which the conduit (6) is mounted and a plurality of panels configured to interconnect with the base (1) to produce a housing (8) for the conduit (6).

A solar collector with reflecting surfaces according to the present invention prevents overheating of the solar collector by reflecting the radiation in a way that the light beams, by means of a first transparent surface, are corrected to the preferred angle and further directed towards channels. On a second transparent surface the beams are directed again and on a third transparent surface the light beams are reflected if in the channels is air. If the working fluid flows through the channels, on the third surface there is no reflection, so the light beams pass through the opaque part of an absorber where the solar radiation is converted into the thermal energy that is then removed by the working fluid.

A solar vapor generator includes an absorber to absorb sunlight and an emitter, in thermal communication with the absorber, to radiatively evaporate a liquid under less than 1 sun illumination and without pressurization. The emitter is physically separated from the liquid, substantially reducing fouling of the emitter. The absorber and the emitter may also be heated to temperatures higher than the boiling point of the liquid and may thus may be used to further superheat the vapor. Solar vapor generation can provide the basis for many sustainable desalination, sanitization, and process heating technologies.

Wherein the plate, the pair of side walls, the top end cap, the bottom end cap are formed of a single material and configured as a single integral component and wherein the plate, the pair of side walls, the top end cap and the bottom end cap are collectively configured to form a cavity. Wherein said top end cap includes a top header, said top header extending the length of said top end cap and said top header extending outward from said top end cap and in a direction away from said cavity.

A solar collector includes a box shaped collection space bounded by a rectangular bottom (10), a frame (12), and an outer rectangular glass pane (14). The box shaped collection space includes therein an inner rectangular glass pane (16) that is disposed in a first direction from the bottom and is separated from the outer rectangular glass pane by spacers (18). An absorber sheet (20) and at least one fluid conducting riser (22) are positioned intermediate of the bottom and the inner rectangular glass pane. At least two ventilation caps (30) extend in overlying relation of respective corners of the solar collector. Inner sides (32I) of the ventilation caps include a pattern (34P, 34Z) of air ventilation passages that provide at least one ventilation channel that extends from outside the collector space to between the inner and outer rectangular glass panes.
