Abstract:
The invention relates to a curtain protector with cooling for thermal or photovoltaic solar panels, for mounting on at least one of said panels, forming a unit. The invention consists of a curtain or blind (5) which opens or closes on a motorized (11) axle (12). The curtain is mounted on a frame (2) comprising rails (9) along which it runs. Gears or rollers (8, 16, 17) can be arranged on the ends of the rails in order to facilitate the movement. At least one extractor (3) facilitating the cooling of the panel by ventilation is arranged between the box (4) and the panel (1). The curtain is closed by the drive of the motorized (11) axle (12) together with a traction mechanism on the other end of the curtain by means of springs, struts (10) and cords (7) or the like. The protector assembly comprises activity and weather condition sensors that activate the motor in order to move the curtain, protecting the panels in the event of over-heating or inactivity.

Systems and methods for concentrating and storing solar energy are provided. A solar energy receiver for use with the systems and methods may include a container for holding a solar absorption material, such as a phase change material, and a cooled cover disposed above the container for condensing and collecting vaporized phase change material collected along an underside of the cover.
Abstract:
Systems and methods for heating a non-combustion chemical reactor with thermal energy from a geothermal heat source are described. A working fluid is directed from the geothermal heat source to the chemical reactor to transfer heat. The working fluid can be circulated in a closed system so that it does not contact material at the geothermal heat source, or in an open system that allows the working fluid to intermix with material at the geothermal heat source. When intermixing with material at the geothermal heat source, the working fluid can transport donor substances at the geothermal heat source to the chemical reactor.
Abstract:
A solar heat collector (10) is disclosed, comprising a storage tank (12) for holding liquid to be heated using solar energy, at least one vacuum chamber (14) to at least partially enclose the storage tank (12), and a transparent heat mirror cover (18) to allow sunlight to enter the solar heat collector (10) to heat the storage tank (12) and to also contain the associated solar energy within the collector. In an example embodiment, an outer wall of the storage tank defines a heat absorber and transfer plate (16), with the transparent heat mirror cover (18) being arranged to cover the heat absorber and transfer plate (16). In an example embodiment, the transparent heat mirror cover allows incoming sunlight to pass through but reflects infrared radiation back to the heat absorber and transfer plate. Alternatively, the transparent heat mirror cover comprises a transparent clear glass cover with a reflective underside.
Abstract:
A protective cover for a solar panel. The cover provides protection for the solar panel from the elements of the weather such as snow, hail, sleet, and windblown debris, and also against overheating of the solar panel during periods of long and intense solar radiation, when the demand for hot water is insufficient to dissipate heat build-up. The cover is constructed of material having heat-insulative properties and provides a barrier layer over the top of the solar panel to reduce the amount of heat transferred to the water tubes.
Abstract:
The present invention is related to a solar panels cleaning, protection and efficiency optimization system (1), that controls the solar panel (3) radiation harvesting in a modular and phased way. The system has a set of solar tubes (5 - 12) cover equipment (2), that are enabled and disabled according with the measurements performed by a thermal sensor (4) placed at the panel (3) exit, or by other conditions defined by the electronics microcontroller (14) of the system, performing also cleaning and protection actions of the tubes (5 - 12) surface, by using a rubber connected to their surface. The present invention is useful to optimize the solar panels energy efficiency, eliminating the problems associated to the overheating, that occurs when the solar availability is high, allowing also to reduce the solar panels maintenance actions.
Abstract:
The invention relates to a thermal solar flat collector, consisting of a heat transfer medium conduction system which is sealed in a water-proof manner at the edges and provided with an inlet and an outlet and which has at least two glass panes, which face the sun and are arranged spaced apart from each other, comprising a heat insulation layer facing away from the sun and a collector bottom, wherein the collector bottom forms the lower wall of the heat transfer medium conduction system and the innermost of the glass panes facing the sun forms the upper wall of the heat transfer medium conduction system, wherein the collector bottom is designed in the form of black glass and the heat insulation layer facing away from the sun is designed in the form of foam glass having closed porosity, having thermal expansion coefficients that are adapted to each other.
Abstract:
A solar collector including a linear receiver and an array of linear mirrors positioned to concentrate sunlight onto the linear receiver, with all of the mirrors in the array tracking solar motion in a direction perpendicular to the longitudinal axis of the receiver, a fraction of the mirrors tracking solar motion in a direction parallel to the longitudinal axis of the receiver and a two- axis steering mechanism adapted to combine the linear images formed by each linear mirror into a single linear image that remains focused on the linear receiver as the mirrors rotate about the two axes, with the linear receiver incorporating a secondary concentrator, and concentrated sunlight heating an atmospheric-pressure gas-phase heat- transfer fluid.
