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 method for concentrated photovoltaic-thermal power generation includes converting a first portion of concentrated sunlight into electrical power when the first portion of concentrated sunlight illuminates an array of photovoltaic cells; and thermally coupling heat generated by the photovoltaic cells into a heat transfer plate. The method also includes cooling the heat transfer plate by flowing heat transfer fluid through an internal path of a cooling block in direct thermal contact with the heat transfer plate; and flowing the heat transfer fluid through a helical tube to absorb thermal energy from a second portion of concentrated sunlight illuminating the helical tube.
