Abstract
Solar panel (1) comprising an absorber element (2), a heat-insulating insulation element (3) placed between the absorber element (2) and an underlayer, and a frame structure (4) surrounding the insulation element (3) and the absorber element (2). The invention is characterized in particular in that said insulation element (3) and said frame structure (4) are integratedly formed into an essentially box-shaped, self-supporting base element (5) having a recess (7) to accommodate said absorber element (2), which base element (5) consists in the main of a foamed plastic material. The solar panel (1) preferably also comprises a transparent covering sheet (6) placed over said absorber element (2).
Claims6
Solar panel (1) comprising an absorber element (2), a heat-insulating insulation element (3) placed between the absorber element (2) and an underlayer, and a frame structure (4) surrounding the insulation element (3) and the absorber element (2), said insulation element (3) and said frame structure (4) are formed integratedly into an essentially box-shaped, self-supporting base element (5) having a recess (7) to accommodate said absorber element (2), which base element (5) consists in the main of a foamed plastic material, wherein the solar panel (1) further comprises a transparent covering sheet (6) placed over said absorber element (2), and wherein said base element (5) has fastening organs for the absorber element (2), characterized in that the recess (7) in the base element (5) accommodates the absorber element (2) in its entirety, including pipe joints (10) located on the absorber element (2) and that said fastening organs (17) are through holes (18) in the base element (5), which holes (18) are adapted to interact by press fit with pipe joints (10) located on the absorber element (2).
Solar panel (1) according to any one or more of the preceding claims, characterized in that said base element (5) is clad with a surface layer (19) of a plastic material, the density of which exceeds the density of said foamed plastic material.
Solar panel (1) according to any one or more of the preceding claims, characterized in that said base element (5) has a recess (16) to accommodate the transparent covering sheet (6), in which recess (16) upwardly facing support surfaces (14, 15) are executed for contact with the covering sheet (6).
Solar panel (1) according to any one or more of the preceding claims, characterized in that said foamed plastic material has a density within the range 20-80 kg/m3, preferably 40-60 kg/m3.
