A hybrid solar panel is described (1) comprising a layer of photovoltaic cells (4) cooled by a cooling system comprising one or more heat pipe devices (16) each including an evaporation side (18) and a condensation side (20) for a thermovector fluid circulating within them. More precisely, the photovoltaic cells (4) are preferably arranged only in correspondence of the evaporation side (18) of the heat pipe devices (16) in such a way that they supply heat flow to the aforesaid evaporation side (18) such that their temperature can be lowered and such as to cause evaporation of the thermovector fluid inside the heat pipe devices (16), which is then carried in the vapour phase toward the condensation side (20). A manifold member (10) is installed next to the condensation side (20), arranged to convey a fluid, particularly water, in a heat exchange relationship with the thermovector fluid within the thermal exchange layer (6). The fluid flowing in the manifold member (10) is heated by the thermovector fluid in the vapour phase which condenses inside the condensation side (20) of each heat pipe device. The layer (2) of photovoltaic cells (4) and the thermal exchange layer (6) are clamped into a back panel (2) by means of a framework preferably made of metal profiled bars. The thermal exchange layer (6) is a metal component wherein the heat pipe devices (16) are made by soldering two sheets of metallic material using roll-bond technology. |
