1. A method of producing a solar panel curved in two directions, the method comprising:
providing a multitude of solar cells, the solar cells showing a photosensitive side and connections to anode and cathode on the side opposite to the photosensitive side;
providing a curved surface, the curved surface transparent or translucent, the curved surface at least locally curved in two directions;
providing two or more flexible foils of an insulating synthetic material with a conductive pattern thereon,
the solar cells are grouped in subgroups, each subgroup associated with an area on the curved surface and one flexible foil;
a solder step comprising, for each of the subgroups, soldering the solar cells of said subgroup to the flexible foil associated with said subgroup or bonding the solar cells of said subgroup to the flexible foil associated with said subgroup with a conductive adhesive;
a positioning step comprising draping the two or more subgroups, each of the subgroups being soldered to or bonded to the flexible foil that is associated with said subgroup, on or in the curved surface; and
a final lamination step comprising laminating the subgroups to the curved surface.
