An eco-smart panel is described comprising a a solar thermal panel, a phase change material, a metal foil layer, and a structural frame constructed of materials including wood studs, gypsum, or fiberglass-reinforced concrete. The materials may be variously configured to create modular systems for fabricating buildings or structures. Eco-smart panels may be utilized to create buildings or structure with enhanced energy efficiency, increased fire resistance, increased flood resistance, and decreased construction cost and time.

A cladding panel that collects and/or emits thermal energy, which includes: a first panel; a second panel with an extrados adhered to an intrados of the first panel, forming a leaktight seal, with a low-relief channel, the channel being attached to the intrados of the first panel to form a conduit; an inlet connector for heat-conducting fluid, connected to a first end of the channel; and an outlet connector for heat-conducting fluid, connected to a second end of the channel, wherein the first panel is made of calibrated laminated ceramic with a flat, smooth intrados and a flat, smooth extrados and has a uniform thickness of 3-6 mm, and the second panel is made of waterproof heat-insulating plastic that is stable up to 120 C.

A solar heat exchanger in which the manifolds are connected together using a threadless connection arrangement in which the end of one manifold tube carries at least two annular seals and the internal bore of the end of the adjacent manifold tube is cammed and when locked, the connection of the two manifolds is resistant to loosening when exposed to repeated thermal expansion and contraction cycles.

The present invention is in the field of solar energy collectors. In particular, the invention is directed to solar energy collectors that operate by concentrating solar radiation onto an absorber using a reflector. The invention may be embodied in the form of a unitary planar solar radiation reflector array having a plurality of upwardly facing reflective surfaces each of which is configured to reflect incident solar radiation, wherein each upwardly facing reflective surface is formed by coating a substrate with a coating material. The coating material may be a metallic coating of substantially even thickness formed by a metal deposition method such as a vapour deposition method or a thermal spray method.

A screw member, a fastening structure, and a connection structure for a solar panel float which can facilitate the fastening operation performed by a screw. A pair of screw members is provided with a male screw member and a female screw member. One of the male screw member and the female screw member has a body portion at least partly inserted into a through-hole provided in an object to be fastened, and a temporary fixing portion provided adjacent to an end of the body portion and locked in the object to be fastened so as to prevent the body portion from deviating from the through-hole during a fastening operation.

An arrangement for producing hot water from solar energy, the arrangement comprising: an elongate solar collector device extending along a longitudinal direction (X) from a first end to an opposite second end, the elongate solar collector device consisting of an elongate profile having walls that in between them define elongate cavities extending from the first end to the second end, the elongate solar collector device having at least one first opening for receiving water into the elongate cavities, and at least one second opening for tapping off water, arranged at a middle part of the elongate solar collector device; and at least one valve adapted to be arranged in a respective one of the at least one second opening, the valve being openable and closable in order to be able to tap off any water housed in the cavities.

A hybrid solar panel, comprising a photovoltaic panel coupled with transparent liquid thermal collector filled with coolant. Role of heat adsorber is coolant selectively transparent in the range of 400-1100 nm. Such panel is coupled with thermal collector by lamination.

Floating element (1) for realizing floating structures for supporting photovoltaic panels and method for producing said floating element (1). The floating element (1) comprises: a first element (2) which can be obtained by injection moulding, which configures a first coupling portion (3); a second element (4) which can be obtained by injection moulding, which configures a second coupling portion (5). The first element (2) and the second element (4) are mutually configured so that the first coupling portion (3) and the second coupling portion (5) can be seal-coupled with respect to each other so that they define a sealed chamber, when coupled.

A photovoltaic panel mounting system utilizes rubber tires to anchor and position photovoltaic panels to face the sun and resist wind forces. The shaded interior cavity of the rubber tires physically and thermally protects electronics and batteries. The tires may be filled with soil, concrete, water, or aggregate to provide further ballasting, enabling a photovoltaic mount system to withstand high velocity winds. Telescoping conduits may house wiring for the system and allow for resizing and reshaping of the mounting system. The mounting system decreases used tire waste and provides low cost components and portability.
