A hybrid solar panel includes a solar photovoltaic panel configured to generate electrical energy by receiving sunlight, a solar thermal panel formed on a lower portion of the solar photovoltaic panel, and a lattice-type refrigerant flow path which is formed inside the solar thermal panel and in which a horizontal guide unit is formed, the horizontal guide unit being configured to guide at least a portion of a refrigerant for cooling the solar photovoltaic panel by absorbing heat generated as sunlight irradiates the solar photovoltaic panel to a horizontal direction.

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 particle receiver includes an inlet, an outlet and multiple tubes rotatably coupled to the inlet and the outlet. The tubes receive particles via the inlet, the particles passing along a passageway of each of the tubes to the outlet. The tubes receive a solar flux as they rotate to heat the particles passing through the tubes. A heat transfer coefficient of the particles is increased by increased mixing via air flowing in the tubes, fins used to mix the particles or via channels via which the particles pass through that increase turnover and mixing of the particles.

A method of forming a concentrated solar power system for generating electricity. The method has three steps. The first step is coupling a plurality of tower segments together onsite at a solar energy concentration field to form a solar tower in a lowered orientation. At least one solar receiver is coupled to the solar tower to form a solar tower assembly. The second step is raising the solar tower assembly to a solar energy collection orientation by pivoting the solar tower assembly about a pivot axis located at a bottom portion of the solar tower. The third step is securing the solar tower assembly in the solar energy collection orientation.

The present invention discloses a receiver for a concentrated thermal system. The thermal system includes a first heat exchange element helically coiled to receive a solar radiation from a first reflector and the second heat exchange element. Further, the first heat exchange element includes a first end and a second end to enable circulation of a heat exchange fluid in the first heat exchange element. The second heat exchange element being a helically coiled element is extending from and fluidically connected to the first end of the first heat exchange element. Further, the second heat exchange element is configured to receive absorb a part of solar radiation to preheat the heat exchange fluid flowing therein.
