Abstract: Solar cell systems are normally made as a number of panel plates sized typically 0.5-1×1 m, with associated mounting means for holding the plates in suitably inclined positions relative to a horizontal or vertical mounting base. According to the invention, these panel plates may advantageously be changed into a lamella-shaped structure, e.g. with a width of only 10-20 cm and, in return, with a much larger length dimension, whereby strips of a solar cell sheet material can be supported by already highly developed and inexpensive carrier systems, whether or not these also serve another purpose with respect to sun shading. A number of relevant advantages is obtained in using carrier laminae made of aluminium.

Abstract: A lamella or panel element and a method of making the same wherein plate profiles are provided along joining edges with cross flanges which, when the profiles are brought together edge to edge, engage each other in an interlocking manner in a transverse direction. The flange portions are locked together by inserting a U-shaped or C-shaped profiled joining member which engages the outside of the flange portions on the side edges with a loose fit. The joining member may be inserted manually and extend over the length of the profiles and, the despite the loose fit, it is nevertheless possible to achieve a strong and tight joining since the long profiles do not extend totally rectilinearly. The joining members are arranged inside cavities of the plate profiles so that the joint members are invisible thereby resulting in advantageously obtaining an entirely smooth surface in the joining areas between the respective plate profiles.
